HDB interior design in Singapore
for BTOs, resales & executive maisonettes.

Full HDB renovations in Singapore typically cost between $28,000 and $80,000 for BTO and resale flats of 3-room to 5-room size. Cosmetic refreshes (paint, lighting, soft furnishing only) start lower. Executive Maisonettes and 3Gen flats with custom carpentry can reach $90,000+.

The biggest cost drivers are carpentry (35–45% of total — kitchen cabinets, wardrobes, TV console, shoe cabinet, storage benches), flooring and tiling (15–20%), and electrical + lighting works (10–15%). Resale flats cost 20–40% more than BTOs because of additional hacking, wet works, and full electrical rewiring.

Every MET Interior quote is fully itemised so you can see exactly where every dollar goes — no inflated markups, no surprise add-ons.

HDB flats are governed by HDB's Renovation Permit (RP) framework. Most renovation works — hacking, electrical rewiring, water-proofing, built-in carpentry near gas or wet areas — require a Renovation Permit submitted by an HDB-registered contractor. The Works by Renovation Contractor Scheme (WRCS) covers notifiable structural and wet works.

MET Interior is HDB-registered, which means we can submit permits directly without relying on a third-party contractor. This matters because unauthorised works can trigger fines, rectification orders, and forfeiture of your 10-year HDB building warranty (BTO) or resale flat fitness certification.

Our team handles RP applications, HDB liaison, contractor insurance, and post-works inspection end-to-end.

A typical HDB renovation in Singapore runs 6 to 12 weeks on-site. BTO renovations sit at the shorter end (6–8 weeks) because there is no existing demolition or wet-works rework. Resale renovations run longer (9–12 weeks) because hacking, waterproofing, and rewiring add 2–4 weeks.

Design development — briefing, 3D renders, material confirmation, costing — adds another 3 to 5 weeks before construction begins. Total BTO project length is usually 10–14 weeks from key collection to move-in; resale is usually 13–18 weeks.

We give every client a dated project timeline with weekly photo updates, so you always know where you stand.
