The covered terrace spans thirty-one feet without a single column in the middle. It opens entirely onto the pool and the pines.

01 — What makes a project different
The difference between a good house and an expensive one comes down to decisions made before anyone breaks ground: where the sun comes in, how the breeze moves through, what you see from the bed when you wake up. Finishes can't fix any of that later.

Aerial pass · descent
The pool has a glass wall — from the lounge below you see the water from inside it. The land sloped, and instead of filling it in, we used it.
03 — From render to house
Drag the handle. On the left, the image the client saw before signing. On the right, the house built from that same point.

04 — Before and after
Mansiones Real, Ponce. The camera never moves — the only thing that changes is the house.
Sheet 02 · San Juan · PR
Aerial pass · out to sea
The whole living floor faces the sea. The roof projects far enough that summer sun never reaches the living room.
05 — How I work
Before a single line gets drawn, you have to stand on the land. The slope, where the sun rises and what you see from each spot decide where everything goes.
In the first meeting you know whether the land supports what you want and what budget range you're in. Not on the third set of drawings.
How you live, how many of you there are, whether you entertain, whether you work from home. The plan comes from that, not from a catalog.
3D images of every important space, from the angles where you'll actually be standing. Changes happen on screen, which is where they're cheap.
Architecture, structure, plumbing and electrical. The contractor bids on something complete, so the price you get back is a real price.
I'm on site for the moments that decide the quality of the house. A structural mistake can't be fixed later — it stays there for forty years.
What was built, drawn the way it ended up. The day you want to expand or sell, that document is worth something.

06 — Ozono Pieces
Concrete planters, benches and pedestals, hand-cast in single-use molds. The same material as the houses, at terrace scale. No two come out alike.
07 — The studio
I've been designing houses in Puerto Rico for ten years. I work directly with the client: the person you sit down with to decide the floor plan is the same one standing on site the day the concrete is poured.
There's no sales team and no middleman. Decisions happen fast, and nobody tells you one thing in the office and something else on site.
08 — Contact
The first conversation is free, and it answers two questions: whether the land supports what you have in mind, and what budget range the project sits in.
