How we scored. 12 things HDB buyers expect on a renovation site in 2026: visible phone, WhatsApp button, budget calculator, real prices on package pages, an ideas blog, a Mandarin version, schema code (so Google reads you correctly), HTTPS done right, Qanvast presence, project pages with proper SEO, a clear booking form, named team. Casa wins three: visible phone, HTTPS, named team. Aphyx model
Quick summary
Casa is one of Singapore's most trusted HDB renovators. The website only shows half of that 19-year reputation.
5,972 organic Google visits a month — worth about $19,956 in equivalent ad spend.SemrushAlready ranking #1 for "casa interior design," "casaid," and "hdb resale renovation." 19 years of word-of-mouth has built real SEO equity. The foundation is here.
92% of that traffic is stuck on 2 pages. The other 23 indexed pages get almost nothing.The homepage absorbs 47%. Another 45% lands on a duplicate http://www.casaid.com.sg/ mirror Google still has indexed. Google sees them as two sites and splits 19 years of authority in half.
No WhatsApp button. No budget calculator. No Mandarin pages. No blog.The four things every HDB buyer in 2026 expects, and your site catches none of them. Swiss Interior already owns 2,141 keywords by writing one blog. Casa hasn't published one article.
One weekend to fix the foundations. One quarter to launch the Mandarin site, the calculator, and a blog. About 14 new enquiries a month.Aphyx Professional Plan + 4 add-ons. Same 19-year brand, finally visible to the visitors who already arrive every day.

12-thing checklist Aphyx model
01 · The site, today
The 19-year brand still works — but the site is missing seven things buyers check first.
A new HDB owner who just collected their keys lands on casaid.com.sg and decides in about 8 seconds whether to stay. These seven things decide that 8 seconds — and right now, none of them are working.
Show me the 7 problems on the homepage 7 items
1
No WhatsApp button anywherePhone 6291 4846 is in the footer, but in 2026 nobody phones a renovation company. Without WhatsApp, half of every enquiry never starts.
2
"100% Transparent Pricing" — but no actual prices on the pageThe package pages list 3-room, 4-room, 5-room, EA — but every "From $XX,XXX" slot is empty. A buyer cannot compare you to anyone.
3
No budget calculator"4 room bto renovation cost" gets 90 searches a month Semrush. Whoever ships a calculator first wins those buyers.
4
No Mandarin version"装修公司" gets 210 monthly searches at very low competition Semrush. The Mandarin-speaking heartland HDB segment is your core market — and there's not one Chinese word on the site.
5
No blog or HDB renovation guidesSwiss Interior built a /blog/ and now ranks for 2,141 keywords (5.6× Casa). They captured "hdb kitchen design ideas," "scandinavian interior design," "bto toilet" — content that was free to write.
6
http://www.casaid.com.sg/ is still live and indexed — that splits your SEO authority in halfGoogle indexes both http and https as separate sites. Every backlink and every search ranking is divided. You're competing with yourself.
7
No schema markup (JSON-LD)That's the structured "introduction" that AI tools and Google read. Without it, ChatGPT will not list Casa when someone asks "best HDB renovation in Singapore" — and that's where 30% of buyers search now.
What's working
Strong SEO equity already in place #1 for "casa interior design," "casaid," "hdb resale renovation." 19 years of word-of-mouth.
Package page is doing the work /hdb-renovation-package/ alone wins 56 keywords and 415 visits a month.
Real awards on the page Top 20 / Top 100 SME / Asia Leading Brand / Preferred Brand. Genuine trust anchors.
5-year warranty Swiss, 9 Creation and Renozone offer 1–3 years. Casa offers 5. This belongs above the fold.
A real Tampines showroom 1 Tampines North Drive 1 #01-24/25, T-Space. Online-only competitors can't match this.
Keyword growth trajectory is up From 173 keywords (April 2025) to 409 (April 2026) Semrush. The brand is gaining altitude on its own.
What's broken or missing
http vs https duplicate Authority split nearly 50/50. One .htaccess rule fixes it.
No WhatsApp · no calculator · no Mandarin · no blog The four basics every HDB buyer expects in 2026.
Not on Qanvast Swiss, 9 Creation, Mr Shopper all listed. Casa is invisible on the platform buyers check first.
"From $XX,XXX" placeholders, no actual prices "100% Transparent Pricing" reads as a hollow claim.
Zero schema markup 19 years of facts about you, told in a language Google can't parse.
Ranking #5 for "interior design singapore" (4,400 searches/mo) but only 0.5% click-through showing in results, getting ignored — the title and snippet need rewriting.
02 · Vs. competitors
Five renovation peers. Each one is one step ahead on one specific thing.
Why they win. Qanvast is not a renovation firm — it's the default platform HDB buyers visit before choosing one. Swiss, 9 Creation, Mr Shopper are all listed. Casa is not. Get on it, gather 5-star reviews, and every "casa interior design qanvast" search comes home to you.
Swiss Interior
Blog leader
2,141 keywords (5.6× Casa) · 5,824 monthly visits · almost all of it from /blog/ Semrush
Why they win. Swiss used 30+ blog articles to capture "4 room hdb renovation ideas," "hdb kitchen design," "bto toilet" and 2,000+ other terms. Casa's monthly visits are similar — but yours all come from brand searches. Open a blog and you double everything.
Why they win. 9 Creation casts the widest net — but each page's traffic is shallow. The lesson: every project case page has full SEO. Casa's project pages (/projects/513c-yishun-street-51/, etc.) currently bring only single-digit visits each — that's headroom.
Renonation
Content + ads
3,330 keywords · 7,932 monthly visits · 44 paid keywords on Google Semrush
Why they win. Renonation is one of the few that combines content + Google Ads. They get 536 paid clicks plus 7,932 organic. Casa runs zero ads — that's a missed lever, not a mark against you.
Carpenters / Renozone
Big-name laggards
Carpenters 971 monthly visits · Renozone 908 · both household names with weak digital Semrush
Why they don't win. Both have far bigger brands than Casa, but their websites are weaker. With a calculator and a blog, Casa overtakes them on Google in one quarter.
The good news
Casa already has 5,972 organic visits and 383 keywords — second only to the platform Qanvast among the names in this brief. 19 years of brand + a wall of awards has done the hard part: trust. What's left is mechanical work — fix the http redirect, ship a Mandarin version, install the calculator, write the blog. The position competitors paid for, your brand earned for free.

Wedge 4
"hdb renovation contractor"
590/mo · CPC $2.79 · schema fix lifts you from #12 to top 5 Semrush
These four wedges add up to about 970 monthly searches Semrush. If Casa lands top 1–3 on each (achievable with 19 years of brand authority + Aphyx schema work), that's around 200 new precision visits a month and roughly 14 new enquiries.
Tell me more — Mandarin "装修公司"
Who's searching. A 50-year-old auntie in Ang Mo Kio, Tampines or Bedok who has just collected the keys to a resale HDB. After dinner she opens her phone and types "装修公司新加坡" hoping for "a fair-priced firm that won't overcharge me." She speaks Mandarin and skips English ads.
Why no competitor owns it. Swiss, 9 Creation, Carpenters, Renozone — all English-only. Renonation has a few Chinese pieces but isn't a renovation firm. In 2026 there is no Singapore HDB renovation company doing serious Mandarin content.
Why Casa is the natural winner. "Casa" is Spanish, but in 19 years your Mandarin-speaking customers have called you "卡萨." A /zh subdirectory with "19 年组屋装修老字号," the 5-year warranty, and the Top 100 SME award in Mandarin — and you become #1 for Chinese renovation searches in Singapore overnight.
"装修公司" monthly searches 210
"hdb 装修" + "bto 装修" ~20
Total Mandarin search volume ~230/mo
CTR at #1 ~30%
New Mandarin visits ~70/mo
Mandarin enquiry rate ~12% (vs ~8% English)
New enquiries ~8/mo
Avg renovation contract ~$35,000
One conservative monthly close = $35,000
The catch. You need a real Mandarin writer, not Google Translate. The voice has to be one a heartland Chinese family will trust on first read: "做了 19 年组屋装修，做过 BTO 也做过转售。Jason 和 Ben 都讲华语。" That's the tone — not a translated brochure.
Tell me more — Renovation budget calculator
Who's searching. A young couple who just won a 4-room BTO ballot. He's 28, an engineer; she's an admin officer. Tight budget. At lunch he Googles "4 room bto renovation cost" because he wants a number before he books showrooms.
Where competitors stand. Qanvast has a calculator, but it's gated behind a sign-up. 9 Creation has price tables but no interactive tool. No local renovator publishes a "input room type + style + scope → see price" widget on the open web.
What the calculator wins for Casa. The visitor enters their inputs, sees an estimate, then taps "WhatsApp Casa for a precise quote." Casa's team receives a WhatsApp message that already says "3-room BTO + Scandinavian + full reno." Reply time drops from ~2 hours to about 5 minutes.
How it ships. Four dropdowns (room type, scope, style, urgency) and one estimate range ("$28,000–$45,000"). A single CTA underneath: "This estimate is built from Casa's 19 years of HDB project data. Tap WhatsApp for a precise quote."
Tell me more — HDB how-to blog cluster
What Swiss Interior already proved. Swiss runs a /blog/ — 30+ articles ranking on the front page for "hdb kitchen design," "4 room hdb renovation ideas," "bto toilet" and 2,000+ other terms. Their blog brings about 4,000 monthly visits. They started 18 months ago. In the same 18 months Casa published zero articles.
Casa's unfair advantage. Casa has 19 years of real project data — Swiss does not. Every article can use Casa's actual project photos, real client questions, real budget numbers. "19-year HDB renovation veteran" beats every other renovation blog in Singapore on credibility.
The 12 articles, in order, all from Semrush-validated keywords:
"HDB hacking rules — what you can and cannot remove"
"4-room BTO renovation budgets: $30K vs $45K vs $60K"
"Resale HDB renovation vs BTO full renovation — 10 real comparisons"
"HDB renovation timeline: from contract to handover, week by week"
"Casa's 19 years: 5 mistakes new HDB owners always make"
"HDB toilet renovation — staying within MCST and BCA rules"
"Can a 5-room HDB get a master ensuite? What's allowed, what's not"
"Should BTO renovation start before key collection?"
"Renovation instalment vs renovation loan — which fits an HDB owner"
"Why Casa offers 5-year warranty — and what it covers"
Each article ships in English and Mandarin. ~1,200–1,500 words. 4–6 real Casa project photos per piece. Bylined by a real team member.
Tell me more — Lifting "hdb renovation contractor" to top 5
The keyword's value. "hdb renovation contractor" — 590 searches/mo, $2.79 CPC. One of the highest-value transactional terms in this category. Casa currently sits around position 12, off the first page entirely.
How to lift it. (1) Rewrite the homepage H1 from "SG's No.1 HDB Renovation" to "HDB Renovation Contractor in Singapore — 19 Years, 5-Year Warranty." That hits the search intent directly. (2) Add LocalBusiness + ContractorService schema. (3) Use structured data to tell Google about the awards, the 5-year warranty, and the 19-year track record.
Realistic projection. With Casa's existing brand authority (rank 8,051) and 19 years of incumbency, this combination should lift the keyword into the top 5 within 6–8 weeks, with top 3 likely. From #12 to #3 takes monthly visits from near-zero to ~100 (CTR ~17%), with ~8% becoming enquiries — about 8 new enquiries per month from this single keyword.

What we recommend for Casa Interior Design
Your Aphyx stack
Professional PlanA bilingual site (English + Mandarin) with home, packages, projects and contact pages · integrated budget calculator · WhatsApp chat widget · 2 helpful articles posted each month · monthly performance report · Aphyx OS dashboard so you can see who's visiting and where they came from.
+ Mandarin site (GEO Optimisation module)casaid.com.sg/zh as a parallel Chinese version. Hreflang language tags so Google understands they're the same brand. A real local Mandarin writer reframes Jason / Ben / Alex as "卡萨 19 年的团队," and the 5-year warranty as "做坏免费重做" — the words a Chinese-speaking family actually trusts.
+ Renovation budget calculator (Custom AI Feature)Four dropdowns: room type, scope, style, urgency. The visitor sees an estimate range (e.g. "$28K–$45K") and a single button: "WhatsApp Casa for the precise quote." Their inputs are pre-filled in the message — your team knows what they want before they reply.
+ SEO + GEO content (2 bilingual posts a month)12 articles over 6 months, English + Mandarin. Targets validated by Semrush (the list is in the Tell-me-more under "HDB how-to blog cluster"). 6–9 months in, expected to add 4,000–6,000 monthly visits — roughly doubling current traffic.
+ CRM ModuleEvery enquiry from WhatsApp / calculator / form gets tagged and tracked. Monthly report on which channel converts best. Auto follow-ups: 30-day satisfaction check, 6-month maintenance offer, 5-year warranty renewal nudge. 19 years of customer history becomes a sellable asset.
What this saves you. Stitching this yourself means 5–6 SaaS subscriptions (Gallabox WhatsApp ~$25/mo, Calendly, Birdeye, Webflow, Airtable CRM, Claude API) — about $580/mo recurring, plus a one-off ~$7,500 to a freelancer to tie them together, with nobody to call when something breaks. With Aphyx it's one bill, one team, one dashboard.

New enquiries ~14/mo
Close rate ~8.5% (industry midpoint 5–10%)
New closes ~1.2/mo
Avg contract $35,000
New revenue ~$42,000/mo
Why this is conservative. 3.5% enquiry conversion is on the low end for renovation sites with WhatsApp + a calculator (peers do 5–7%). 8.5% close rate is the industry midpoint — Casa's 19-year reputation should beat that. We've kept the numbers cautious; actual returns are more likely to be higher.
What we did not count. (1) Repeat customer revenue from the CRM (5-year warranty servicing, kitchen refresh after 8 years); (2) Mandarin site spillover into 小红书 word-of-mouth — Chinese-speaking Singapore loves peer reviews; (3) AI-answer visibility once schema is live (ChatGPT and Perplexity start naming Casa for HDB renovation queries — invisible traffic that compounds).
One important note
The WhatsApp widget and AI helper's job is to greet, ask 4 qualifying questions (room type / budget / scope / move-in), and forward the lead to Jason / Ben / Alex — never to make design or pricing decisions. Those judgments belong to your 19-year-experienced team. The AI saves time on intake; the senior designers still close the deal.
05 · 9 things to fix, in order
Three groups: this week, this quarter, and later.
Do this week
Stop the leak
3 fixes · one weekend
Redirect http://www.casaid.com.sg/ to https
One .htaccess rule. Immediately re-merges the 45% of authority Google has been splitting in two.
1 hour · Aphyx does itWhy this single fix is worth so much
Today. Semrush sees two distinct "homepage URLs" for Casa: https://casaid.com.sg/ (193 keywords, 2,816 visits) and http://www.casaid.com.sg/ (72 keywords, 2,669 visits). Google treats them as separate sites. 19 years of backlinks, brand mentions, and reviews are split across two domains.
After. All http traffic 301-redirects to https. The two URLs collapse into one. 4–6 weeks after Google re-crawls, Casa's authority rank should lift from 8,051 to roughly 5,000–5,500 — almost-free movement.
How. One redirect rule on the WordPress server. Confirm "preferred domain" in Google Search Console. Done in an hour.
Add a WhatsApp button on every page
A floating green button bottom-right, on every page. Tap once → opens WhatsApp with a context-pre-filled message.
4 hours · Aphyx does itWhat the WhatsApp widget actually does
Customer view. A visitor is on a 4-room BTO Scandinavian project page. They love it and want to ask "can you do this in a 5-room?" Today they have to find your phone number, dial, give their name, explain the project ID — five obstacles. With WhatsApp, they tap once and the message is pre-filled with the project name and the question.
Team view. Jason / Ben / Alex receive a WhatsApp that already says where the customer was and what they wanted. Reply time drops from "5 minutes of figuring out who they are" to "here's a quote range." They reach more enquiries with the same staffing.
The after-hours bonus. Most HDB buyers Google renovations between 8 pm and 10 am (after work, after kids' bedtime). The widget catches that traffic — the AI helper collects info, and your team replies the next day.
Rewrite homepage H1 + put 5-year warranty above the fold
"SG's No.1 HDB Renovation" → "HDB Renovation Contractor — 19 Years, 5-Year Warranty." "5-Year Warranty" + "Top 100 SME 2024" go above the fold in large type.
2 hours · Aphyx does itWhy these two changes matter so much
Problem with "SG's No.1 HDB Renovation." Google deprioritises unverifiable superlatives, and CCCS may flag them. Replace with verifiable facts — "19 Years" + "5-Year Warranty" — and you keep both Google and the regulator happy.
The 5-year warranty fight. Swiss Interior offers 1 year. 9 Creation offers 2. Renozone offers 3. Casa offers 5 — the longest in the category. Today this fact is buried in small footer text. Above the fold, it's the single biggest reason a comparison-shopping HDB buyer picks Casa.
SEO win. Putting "HDB Renovation Contractor" in H1, paired with schema markup, should lift the keyword "hdb renovation contractor" (590/mo, $2.79 CPC) from rank ~12 to top 5 within 3 months.
Do this quarter
Turn traffic into enquiries
3 builds · 4–6 weeks
Renovation budget calculator
Four dropdowns: room type, scope, style, urgency. Submit → estimate range $28K–$45K + WhatsApp button.
Without the calculator. Visitor lands → looks at packages → sees empty "From $XX,XXX" → has no idea if they can afford it → fears a sales pitch on the contact form → closes the tab. Roughly 99% drop off here.
With it. Visitor fills four simple inputs → sees "3-room BTO Scandinavian full reno ≈ $32,000–$48,000" → knows their $40K budget fits → taps WhatsApp. Your team has the entire context up front and can quote within 20 minutes.
SEO bonus. The calculator page (/renovation-calculator) starts ranking for "4 room bto renovation cost," "hdb resale renovation cost," and the rest of the budget cluster. None of these terms have a Singapore renovator who exposes prices openly — Casa would be first.
Mandarin parallel site (/zh)
Full Chinese version of the entire site. Real Mandarin writer (not Google Translate). Jason / Ben / Alex re-introduced in language a Chinese-speaking family actually uses.
3 weeks · Aphyx writes + buildsThe single biggest open opportunity in this brief
Why nobody owns it. Swiss, 9 Creation, Carpenters, Renozone — all English-only. There is no Singapore HDB renovation firm with a serious Mandarin site in 2026. The first to ship locks in 6–12 months of effective monopoly on Mandarin renovation searches.
Who lands on the Mandarin pages. (1) 50–60-year-old retirees buying a resale flat for renovation; (2) 30-year-olds helping Mandarin-only parents compare firms; (3) returning Singaporeans wanting "a designer who speaks our language"; (4) Foodpanda / Grab earners who default to Mandarin search; (5) AI assistants (Baidu, ChatGPT in Mandarin mode) that will start surfacing Casa because no other firm is there.
What ships in v1. Mandarin homepage (with 19-year story + 5-year warranty + Top 100 SME), Mandarin package pages, 5–8 Mandarin project case studies, Mandarin contact page, header language toggle. Written by a real local Mandarin writer with renovation industry context. Aphyx hires the writer; one of Casa's Mandarin-speaking staff signs off.
List on Qanvast + activate review pipeline
Submit firm profile, 12 project case studies, 5-year warranty proof. Activate a 50-customer outreach to seed reviews.
Qanvast's grip on the category. 54,237 monthly visits, 17,479 keywords Semrush. HDB buyers visit Qanvast before choosing a renovator — this is the default behaviour, not an option. Swiss, 9 Creation, Mr Shopper are listed. Casa missing here is like a Singapore restaurant missing from the local listings everyone checks.
How. (1) Submit profile (free); (2) Upload 12 real project case studies — your 19-year archive is an unfair advantage; (3) Email the last 50 happy customers asking for a Qanvast review; first week typically yields 8–12 5-star reviews; (4) Embed Qanvast badge on casaid.com.sg homepage so the rating displays automatically.
3 months later. ~30 5-star reviews on Qanvast. Casa has its own Qanvast brand page. Visitors searching "hdb renovation" on Qanvast see Casa surface — at 54K monthly visits, that's an estimated 200–400 referrals back to the Casa site each month.
Do later
Long-term assets
From month 3 onward
Two bilingual blog posts a month
12 deep articles over 6 months, English + Mandarin. The exact list is in the Wedge 3 deep-dive.
Swiss Interior's proof. 2,141 keywords (5.6× Casa) — and 80% of those are blog URLs. Swiss took ~18 months to write 30+ articles, ~1.5–2 a month. Casa wrote zero in those same 18 months.
Casa's edge. 19 years of project archive — Swiss has nothing of the sort. Every article uses Casa's real project photos, real client questions, real budget data. "19-year HDB veteran" beats every other renovation blog on credibility.
Trajectory. Article 1: ranks for "hdb hacking rules" within 4–6 weeks. Article 6: blog brings ~1,000–1,500 visits/mo total. Article 12: blog traffic exceeds the current homepage traffic (5,972) — Casa's site doubles, all of it free SEO.
Xiaohongshu / TikTok content engine
1–2 60-second videos a week: real project reveals, Jason answering Mandarin Q&A, "what 5-year warranty actually covers" walkthroughs.
1–2 videos/week · 6 monthsWhy Xiaohongshu is the Mandarin word-of-mouth battleground
How Mandarin-speaking Singapore picks a renovator now. In 2026, Mandarin-speaking 30–55-year-olds use Xiaohongshu and Douyin/TikTok as their top renovation reference. Pinterest is niche, Qanvast is English. None of Swiss / 9 Creation / Carpenters has any Xiaohongshu presence — they're all on English Instagram.
Weekly content menu. (1) 60-second "before / after" reels with three photos and overlay text; (2) Jason or Ben answering one Mandarin renovation question on camera (e.g. "3-room BTO Scandinavian budget"); (3) "Does the 5-year warranty actually pay out?" — a real example; (4) Customer interview vignettes; (5) "Common HDB renovation mistakes" series.
Trajectory. Month 3: 800–1,500 followers. Month 6: 3,000–5,000. Month 12: ~8–15 enquiries a month coming directly from Xiaohongshu, with above-average close rates (the audience is high-trust and pre-qualified). Aphyx sets up the account, designs the content, edits, posts, and tracks performance.
Schema markup + AI-answer optimisation
Add LocalBusiness, Service, Review and Project schema across the site. Make Casa visible in ChatGPT, Perplexity, Google AI answers.
2 weeks · Aphyx implementsWhat schema is and why 2026 is the year it matters
What schema does. Schema is structured "self-introduction" code that's invisible to humans but read by Google and AI. It tells ChatGPT "this is a Tampines-based HDB renovation firm, 19 years old, 5-year warranty, phone 6291 4846, hours 9–6." Without it, the AI guesses — and right now ChatGPT does not surface Casa for "best HDB renovation in Singapore."
The 2026 search shift. A growing share of HDB buyers ask ChatGPT or Perplexity directly: "I just got a 4-room BTO, my budget is $40K, recommend three renovators." The answers come from sites with schema. Swiss has it. Casa does not.
What ships. (1) LocalBusiness schema on the homepage (address, phone, hours); (2) Service schema on package pages (price ranges, warranty); (3) Project schema on case study pages (room type, style, completion date); (4) Award schema on the homepage awards block. All live within one week.
06 · A buyer's day
Meet "Ah Qiang," 35, just collected his 4-room BTO keys. 4 of the 6 steps are broken.
Ah Qiang is an engineer. His wife Lihua is an accountant. Two young kids. Renovation + furniture budget about $40K. Lihua mostly speaks Mandarin and watches Chinese short-video content more than English search results. One Sunday evening they pick up their phones to compare renovators.
Step 1
Find Casa
Half OK
Ah Qiang Googles "4 room bto renovation cost" — Casa isn't on the first page. Only the brand search "casa interior design" finds you.
Step 2
Browse
Broken
Homepage H1 is in English. Lihua, who reads in Mandarin, can't follow "transparent pricing." She closes the tab.
Step 3
Check budget
Broken
Package page says "From $XX,XXX" — empty. No calculator. Ah Qiang can't tell if $40K is enough.
Step 4

After completion there's no auto-review request. Casa has no Qanvast page. Great word-of-mouth never becomes a digital asset.
Steps 1–4 all happen before Ah Qiang ever meets Jason — these are the "find you" stages. Step 5 he wins as soon as he walks in, but with the first four broken he probably never shows up. Step 6 the actual reno is brilliant, but it doesn't compound. This 90-day plan fixes Steps 1–4 first. Excellent in-person service can't save a visitor who never opens the door.
Singapore's HDB renovation, the 19-year Casa. English and Mandarin, 5-year warranty, designers who speak both heartland Chinese families and young BTO owners.Our recommendation
Qanvast owns "the platform." Swiss owns "blog content." 9 Creation owns "broad reach." Renonation owns "content + ads." Casa's open lane: the most experienced, longest-warrantied, first-bilingual local HDB specialist in Singapore — 19-year track record + 5-year warranty + a real bilingual team. This isn't "another renovation firm." This is "the Casa for HDB families" — the one that has been renovating two generations of homes. Nobody else can occupy this position because nobody else has all three: 19 years of in-house project data, a real bilingual team, and the longest warranty in the category.
