Presale platforms for property developers

Selling an unbuilt building is a strange kind of selling. There's nothing to walk through and nothing to photograph. The buyer has to believe in something that doesn't exist yet.

We build what makes them believe: a digital sales gallery. It's one URL where a buyer orbits the tower, slices to a floor, taps a residence, sees the actual view from that elevation, and reserves it.

Explore Solmara → (our concept build). Ninety-two residences, 41 floors, live inventory, launch-day simulation. Solmara is a fictional development, self-initiated by this studio. It's a demonstration, and nothing in it is for sale.

What a presale platform includes

Cinematic arrival. A scroll-driven Three.js sequence: you approach over the water, the tower resolves out of a blueprint into golden hour, and the windows light up at dusk. It's real-time 3D instead of video, so it runs on a phone, and the estimates we've seen put 70% of your buyers on one.

3D unit explorer. This is what drives the purchase. Buyers orbit the building, slice it by floor, and tap any residence. Availability is colour-coded by status. Filters for beds, price band, and exposure dim the model in sync, and a view-from-this-floor simulation lets a buyer on 26 see what 26 actually sees.

Live inventory. Available / reserved / sold, updated in real time. The demo runs on deterministic seed data with a Supabase-shaped adapter behind it, so going live takes a configuration change and no rebuild.

Launch-day simulation. Units flip to reserved on screen while buyer-city notifications pop up and a counter runs. These are the most persuasive sixty seconds in a developer pitch, because they make sales velocity visible before it happens.

Reserve flow. Unit summary, date and time selection, contact step, confirmation. It's modelled on the patterns buyers already know from Zillow, with copy that explains the refundable hold and a reservation agreement that arrives for e-signature.

Sales-centre kiosk. The same build, installed as a PWA on the iPads in your physical sales gallery. Works offline. No app store.

Bilingual, natively. Pre-construction buyers in South Florida and Texas are heavily Spanish-speaking, and LatAm investors are a large share of the market. We write the Spanish ourselves instead of translating it (details here).

The part that frees up financing

Banks funding pre-construction want demonstrable presale evidence before they release a construction loan.

A digital sales gallery records exactly that: which units drew interest, how long buyers spent on them, which price bands moved, and where demand clustered by floor and exposure. That's market-demand data a lender can actually evaluate, which is more than you can say for a spreadsheet of hopes.

Most developers commission the 3D as marketing. The reporting layer underneath it is worth more.

Who this is for

Founder-led developers with a 40–120 unit project in coastal Florida, on the Texas Gulf, or in any market where pre-construction sells on velocity. It's typically a first or second project. There's no procurement department, and the developer needs bank-ready presale evidence urgently.

If you have a 600-unit portfolio and an in-house marketing team, you already have vendors. We're built for the developer who needs one studio to deliver the whole presale stack instead of stitching together a CGI house, a web agency, and a CRM consultant.

What it costs

Across this industry, the quotes we've seen put the full presale digital stack (brand, launch site, 3D sales gallery, portals) at $40,000–$120,000 per launch. Interactive 3D condo-finders show up in those quotes as an accepted line item, and they aren't treated as an upsell. The premium WebGL builds we've seen run $50,000–$200,000 across sectors.

We scope in that same range. Every build starts with a paid discovery sprint, and we credit it against the build. See pricing for how we structure it.

Common questions

Do you do the CGI renders too? We produce the real-time 3D, which is the interactive part. For photoreal still renders and film, we direct and coordinate specialists and quote them separately, so you can see how the cost splits.

Can it connect to our CRM? Yes. Leads flow out to whatever you use. The demo saves data locally, while a production build writes to your database and pushes to your CRM.

What if the building design changes mid-presale? It will, and that's normal. The unit model is data-driven, so a floor-plan revision or a repricing means editing data. Nothing has to be re-rendered.

How long does it take? A full presale platform is a 3–5 month build. A focused launch site with a 3D explorer is faster. We phase the work so you have something sellable before the whole thing is finished.

Is Solmara a real development? No. Solmara is fictional and self-initiated, and it says so on every page. We built it because selling an unbuilt building means the deliverable is always synthetic at launch, so a concept build is the same kind of work as a real one. We will never publicly redesign a real developer's project to pitch them.

Can you do this for a hotel or resort instead? Yes. The same stack (3D property, live availability, concierge, portals) re-skins onto boutique hospitality, the closest neighbouring category.
