The verdict in three sentences
For a Singapore developer launching 2 to 4 new projects a year, a serious website costs SGD 80,000 to 200,000, plus a synced unit-availability module of SGD 8,000 to 18,000. The real profitability metric is cost per buyer lead, which should fall to SGD 60 to 120 when property portals and agency co-broking often cost SGD 200 to 450 per qualified lead. A reusable project-page template brings each new launch from 8 weeks down to about 2 weeks of build time.
What a developer website that sells units must include
A developer website is not a brochure. It must answer three buyer questions within seconds: which unit is still available, at what price, and how to register interest. In Singapore, where new private condominium prices commonly exceed SGD 2,200 to 3,000 psf outside the core central region, buyers compare everything before booking a showflat visit.
| Component | Commercial role | 2026 range (SGD) |
|---|---|---|
| Design and project-page template | Launch each project in about 2 weeks | 20,000 to 45,000 |
| Filterable unit chart (type, floor, facing, price) | Qualify the lead before the call | 12,000 to 28,000 |
| 2D/3D floor plans and virtual showflat | Reduce unproductive showflat visits | 8,000 to 20,000 (excl. 3D production) |
| Expression of Interest and balloting registration | Capture hot intent around launch weekend | 8,000 to 18,000 |
| Affordability calculator (TDSR, ABSD, stamp duty) | Reassure investors and upgraders | 5,000 to 12,000 |
| SEO and district pages (D15, D19, Tengah) | Organic traffic outside portals | 10,000 to 25,000 |
| Conversion tracking and CRM connection | Measure cost per lead | 5,000 to 12,000 |
3D production (renders, navigable model) usually sits in the architect's or a specialist studio's budget, typically SGD 15,000 to 60,000 per project. The website simply needs to display it without slowing pages down on mobile.
The synced unit module: the line item that changes everything
The main frustration for buyers is asking about a 3-bedroom unit already sold. A chart updated manually by the sales team quickly falls 48 hours to a week behind. Syncing with the sales or CRM system fixes this, especially during launch weekends when hundreds of units can move in two days.
| Option | Unit updates | Initial cost (SGD) | Estimated annual cost (SGD) |
|---|---|---|---|
| Manual entry in the CMS | Depends on team availability | 0 | 6,000 to 12,000 in staff time |
| Scheduled nightly CSV import | Next day | 5,000 to 8,000 | 1,000 to 2,000 |
| API connector to the sales system | Real time or every 15 min | 8,000 to 18,000 | 2,000 to 4,000 |
| Vendor widget (iframe) | Real time | 0 to 3,000 | Included in licence, weak SEO |
The iframe widget looks cheap, but its units are not indexed by Google and it often breaks the mobile experience. For a developer targeting 30% of leads from organic search, the API connector is the rational choice.
Overall budget by developer profile
| Profile | Projects/year | Initial website (SGD) | Maintenance and changes (SGD/year) | Timeline |
|---|---|---|---|---|
| Boutique developer, 30 to 80 units per project | 1 | 60,000 to 90,000 | 10,000 to 18,000 | 10 weeks |
| Mid-size developer | 2 to 4 | 90,000 to 150,000 | 18,000 to 30,000 | 12 to 14 weeks |
| Listed group with a strong brand | 5 to 10 | 150,000 to 200,000+ | 30,000 to 60,000 | 16 to 20 weeks |
| Adding a project on an existing template | 1 | 6,000 to 14,000 | included | 2 weeks |
These are 2026 estimates for a specialist agency. A generalist agency may quote SGD 40,000, then bill every unit chart as custom development.

Kolonell builds websites that attract clients, optimized for the Sénégalese market. Free quote in 2 minutes.
Rachel, head of marketing at a Singapore developer launching 3 projects a year (about 900 units), buys leads from portals and co-broking: 1,200 leads a year at an average SGD 300, or SGD 360,000. She invests SGD 130,000 in a website with a unit connector, plus SGD 25,000 a year in maintenance and SGD 90,000 in targeted search campaigns. The site generates 1,500 leads in year one: cost per lead = (130,000 + 25,000 + 90,000) / 1,500 = SGD 163 in year one, then (25,000 + 90,000) / 1,500 = SGD 77 from year two. At a 3% conversion rate, that is 45 additional sales a year with less dependence on portals.
FAQ
How much does an additional project page cost once the site is live?
On a well-built template, budget SGD 6,000 to 14,000 per project, including units, 3D visuals and copy. Going live takes about 2 weeks once the architect's assets arrive.
One website per project or a single corporate site?
A single site with one page per project concentrates SEO authority and costs 30 to 50% less to maintain. Dedicated microsites only make sense for flagship projects above 500 units with their own brand.
Can we collect an option fee online?
You can take an online deposit for registration, but the Option to Purchase and the 5% booking fee remain governed by the Housing Developers rules and handled by the sales team. Online payment mainly secures the balloting slot.
What timeline for a full website?
Allow 12 to 14 weeks for a mid-size developer, including 2 to 3 weeks for the sales-system connector. A fixed launch date means starting at least 4 months before the preview weekend.
What cost per lead should we target?
SGD 60 to 120 from year two, against SGD 200 to 450 through portals and co-broking. Per-project conversion tracking lets you cut campaigns that exceed SGD 150.
Let's scope your project. Share your upcoming launches, your sales system and your calendar, and we will price a website between SGD 80,000 and 200,000 deliverable in 12 to 16 weeks. Detailed quote within 48 h. WhatsApp +221 77 596 93 33.
