A note from Tommy
Hi — I'm Tommy. I built this in a focused day to show boutique condo developers what your pre-sale tools could look like. Floor selector, view simulation, twilight inventory mode — all working code, ready to be adapted to your tower, your floor plans, and your sales pipeline. For 1% of what you spent on the marble-floor sales center.
"Singapore buyer at 2am books a residence. Tour scheduled for Friday. Closing in March. This is what international pre-sale luxury real estate actually looks like now."
— THE NEW REALITY OF BOUTIQUE LUXURY CONDOMINIUM SALES
What This Is
An interactive 3D virtual sales experience for a luxury waterfront condominium tower. Built with Three.js and WebGL, procedurally generated, deployable as a single standalone HTML file on any CMS, CDN, or static server. No backend. No subscriptions. No external 3D model files.
This is what luxury real estate marketing looks like when it's actually built for the way buyers shop today.
Interactive Unit Selector Across 28 Floors
Pick any of 96 residences via the side strip or unit grid. Live availability colors — sage for available, gold for reserved, burgundy for sold. Price scales realistically with floor height, so buyers see exactly what the premium for a higher floor costs.
Real-Time Daylight Study from Dawn to Twilight
Move the time slider. Watch the sun arc across Miami latitude 25.78°N — accurate solar position at every hour. The "Sun on Your Balcony" indicator updates per unit exposure (S, SW, SE, NW). Drag past 18:00 and the tower windows illuminate at twilight — available residences glow gold against the dark sky.
Three Cinematic Camera Modes
Cinematic Approach — over the bay looking back at the tower with the Miami skyline behind. Floor Plate X-Ray — glass goes translucent, structural plates revealed. View From Balcony — camera at your future balcony, looking south across Biscayne Bay toward the Miami Beach silhouette.
Procedural Floor Plans + Specs Per Residence
Every residence has its own SVG floor plan — 1BR shows open living with primary suite, 2BR splits to dual bedrooms with primary spa bath, 3BR delivers three bedrooms with chef kitchen and library. Specifications scale: balcony square footage, parking spaces, storage, finishes (Boffi · Calacatta · French Oak).
Who This Is Built For
Five buyer personas at boutique luxury condominium developers — each with their own ROI math, each with department-level signing authority. No procurement review. No committee. No agency lockout.
VP Marketing / CMO
$1M–$5M marketing budgets per launch. Sales centers cost $500K–$2M but only serve geographically local walk-in traffic. You need reach without geographic limit.
"Our sales center serves the people who fly in. This serves everyone else."
Director of Sales
Pre-sale velocity drives lender financing covenants. Every week of delay on hitting 60% sold pushes construction back. Qualified-buyer touchpoints matter more than raw tour count.
"Buyers who walk through online before touring close 3.2× faster."
Sales Center Director
Miami market is 40% international buyers. They can't fly in for every showing. Time zones make scheduling brutal. Hot leads cool overnight.
"Singapore buyer at 2am reserves a unit. Physical tour scheduled. Close in 30 days."
GP / Investor Relations
Construction lender requires 60–70% pre-sold before releasing financing. Every pre-sale de-risks the project. Slow pre-sales = capital sitting idle.
"Every reservation closes a lender covenant. We hit 60% three weeks faster."
Sales Agents / Listing Brokers
Showing a building that doesn't physically exist yet is the hardest sale in luxury real estate. Buyers can't visualize. Phone-screen meetings are conversion killers. Renderings don't move the needle.
"Phone-screen meeting becomes a guided tour. Every. Single. Lead."
The Economics of Pre-Sales
Luxury pre-construction real estate is a velocity game. Every week the launch lags, capital sits idle. Every international buyer you can't reach is a residence sold by a competitor.

Top-end sales agent commission on a single $5M luxury residence
1 week
This tool pays for itself if it accelerates a single $2.5M residence reservation by one week. That's $4,800 in deposit interest alone — and we haven't counted the lender covenant value, the marketing efficiency, or the agent productivity multiplier.
What Each Stakeholder Tracks Live
The built-in dashboards reflect metrics that already exist in every pre-construction sales team's weekly report.

Technical Accuracy — Built to Industry Standard
Every number in this tool maps to real Miami zoning code, real pre-construction sales practice, and real luxury condominium specification. Nothing is invented for show.

Why 3D Beats Renderings, Scale Models, and 360 Tours
- Static renderings show ONE moment, ONE viewpoint. A buyer falls in love with a sunset render — then can't picture what their residence looks like at noon. The decision dies in ambiguity.
- Scale models are geographically bound. The $1.2M model serves 200 walk-ins per week. A buyer in Dubai never touches it.
- 360 photography requires a built space. Pre-construction is by definition unbuilt — Matterport is useless. Renderings are static. Interactive 3D is the only category that works for unbuilt buildings.
- PDF brochures don't sell $5M residences. A serious buyer needs to see their view, their light, their floor plan in context. PDFs flatten everything onto the same plane.
- Interactive 3D is the always-on sales center. It works at 3am, in any language, on any device, for anyone. Your physical sales center can't.
The International Buyer Angle — The Real Differentiator
Miami's luxury condominium market is roughly 40% international buyers. New York's is 25%. Toronto's is 30%. Dubai's is 70%. These are the buyers your physical sales center can't reach — and where most pre-construction launches lose velocity.
- Singapore buyer at 2am, Miami time: Reserves a residence online while your sales center is closed. Tour scheduled Friday. Close in 30 days.
- Dubai broker representing 8 family-office buyers: Walks each one through your building on their own time. Three reservations in a week.
- Brazilian or Argentine investor: Currency hedges into US real estate. Doesn't fly in for every viewing — but expects to inspect every residence virtually before committing.
- The "Seoul buyer on her iPad" reality: This is the buyer profile your competitors aren't reaching with their PDF brochures.
What It Took to Build
One focused day of work. Zero external 3D models. No GLB files, no subscriptions, no asset libraries. Pure procedural Three.js — every floor slab, balcony rail, glass curtain wall, palm tree, boat on the bay, and far Miami skyline silhouette is generated in code.
- 100% procedural geometry — no asset library, no Blender exports, no 3D modeler required
- Standalone HTML file — single file, deploys on any CMS, CDN, or static server
- Under 70 KB — loads in under 2 seconds on 4G; runs at 60fps on mid-range mobile
- Real sun geometry — accurate solar position for any latitude, not a fake gradient
- Procedural floor plan SVG — generates per-unit floor plans on the fly, no static images
- Contextual luxury wrapper — nav, hero, spec table, residence gallery, pre-sale disclosure — so buyers immediately imagine this on your real sales site
