Interior Design Website Design in Singapore

Short answer: a homeowner spends S$50,000 to S$81,600 on a 4-room HDB renovation, per Qanvast's 2026 estimates, and checks an interior design firm's website for proof before sending an enquiry. The site has to show projects like theirs, a budget range, HDB and CaseTrust standing, and a form that qualifies the job. The sections below cover each part and what the site costs.

What do homeowners check on an interior design site?

Renovation is the second-largest purchase most Singapore households make, and the website is where the shortlist is built. Qanvast's 2026 renovation cost estimates, published 12 February 2026 from 2025 medians across 341 BTO and 449 resale projects, put a 4-room BTO at S$50,000 to S$60,000 and a 4-room resale at S$70,000 to S$81,600.

At that price, visitors check specific things:

• Projects like theirs. A 4-room resale owner wants to see 4-room resale projects, not a landed house.
• Budget range. A price band per flat type, or a starting figure per project. Firms that publish none lose the visitor to a portal that does.
• HDB listing. For works that need HDB approval, homeowners must engage a contractor on HDB's Directory of Renovation Contractors. State the listing on the site.
• CaseTrust accreditation. CaseTrust-accredited renovation businesses must hold a deposit performance bond, use the CaseTrust standard renovation contract and cap the initial deposit at 20% of the contract. If you hold it, show it with the logo and a sentence on what it protects.
• Reviews. Google reviews with replies, and reviews on the portals you list on.
• Timeline. How many weeks a typical 4-room takes, and when the firm can start.
• Who does the work. Designers by name, and whether carpentry and wet works are in-house or subcontracted.

Put these on the home page in that order. Style photos come after the facts, not instead of them.

How should portfolios be structured?

A portfolio is a filter, not a gallery. The visitor wants to find the one project that matches their flat, then read everything about it.

Structure in two levels.

Level 1, the index. Filters by property type (BTO, resale HDB, condo, landed, commercial), flat type (3-, 4-, 5-room, executive), budget band and style. Each card shows one photo, flat type, budget band and estate.

Level 2, one page per project. Each project is its own URL with:

• Flat type, floor area in square metres, estate or district
• Budget band and what it covered (carpentry, wet works, electrical, flooring)
• Duration in weeks, from start to handover
• Scope: full or partial, which rooms
• 8 to 15 photos, with before photos where the client allows
• Materials and brands used, since homeowners search those terms
• The designer's name and a link to enquire about a similar project

One page per project matters for search. A search such as "4-room resale renovation Tampines" can land on a project page that states those words in text. A single long gallery page cannot rank for any of them.

Two rules on photos: compress for mobile, since Statcounter puts mobile at 56.86% of Singapore web traffic, and get written permission from the homeowner before publishing the estate name or the interior.

How do enquiry forms qualify budget and scope?

An interior firm's time goes into site visits and quotes. The form's job is to make sure each visit is worth it.

Six or seven fields, on one screen, with a WhatsApp button next to it for people who would rather talk. Each submission should land in a database the firm owns, with the budget band and property type as columns, so the sales lead can sort by fit each morning. A form tool that emails a PDF cannot do that.

Reply time decides conversion. The homeowner has usually sent the same enquiry to three firms. Send a WhatsApp acknowledgment within minutes with two or three matching project links, then book the visit. Our note on WhatsApp versus contact forms covers the record-keeping side.

Collect only what you need and state why. The PDPA's data protection obligations include purpose limitation and retention limitation, so floor plans and photos from enquiries that did not proceed should be deleted on a schedule.

How do interior firms rank for local searches?

Interior design searches are local by nature: the homeowner wants a firm that will come to their flat. Google states that local results rank on relevance, distance and prominence, that complete and accurate profiles appear more often, and that reviews and ratings help.

• Google Business Profile. Showroom or office address, the Interior designer category, hours, photos of completed projects, and a link to the portfolio index. Collect reviews after each handover and reply to all of them.
• Project pages that name places. Estate, town and flat type in the page title and first paragraph. Twenty project pages across ten estates cover more searches than one services page.
• Consistent facts. Name, address and phone identical on the site, the profile and every portal listing.
• Structured data. LocalBusiness markup with address, geo, opening hours and the same phone number, per Google's local business guidance.
• Portals as a channel, not a home. Listing on Qanvast or similar brings enquiries, but the firm's own site is the page a homeowner opens to verify the firm, and the only page where the firm controls the facts.
• Plain-text answers. State price bands, duration and HDB listing in sentences. AI answers and Google's AI features draw on text they can quote.

Avoid one thing: a page per town with the same text and the town name swapped. Google treats these as thin pages. Project pages carry the location naturally.

What does an interior design website cost?

An interior design site is a portfolio with a database behind it: an index with filters, a page template for projects, an enquiry form that stores structured leads, and a Business Profile that points at it.

cense quotes a website, or a website with infrastructure, in full before work starts. The full price is quoted before work starts. The first draft arrives 14 days after one call, with up to 20 rounds of edits. There is S$0 monthly maintenance, and the firm owns the domain, code, hosting and lead data.

What an interior design website quote should list:

• Portfolio index with filters by property type, flat type and budget band
• Project page template the firm can add to without a developer
• Enquiry form with budget and scope fields, stored in the firm's own database, with WhatsApp handoff
• Photo compression and mobile layout
• Google Business Profile set-up and LocalBusiness structured data
• Credentials section for HDB listing and CaseTrust accreditation
• A redirect map if a previous site exists

See web design Singapore for the build, and the website design cost guide for how the ranges compare with published agency prices.

What cense does

cense builds portfolio websites for Singapore and Hong Kong firms, with the enquiry form built in-house so every lead, with its budget band and property type, lands in the firm's own database. Pricing is quoted in full before work starts. See web design Singapore.
