Describe a building. Get drawings and a budget.
One prompt. A million outcomes.
Terraza is an AI engine for buildings. Describe what you want in plain language and it drafts the floor plans, the sections, the budget, even the renders. The engine does the drawing. You tailor the result.
The product
AI engineThree commands do the work you dread.
The whole app is three words. Pick one, answer a few plain questions, and the engine generates the drawing or the budget. No flags, no config screens, no CAD wrestling. You just tailor the result.
Floor plans from a sentence.
Tell it the building type, the area, the floors, and the rooms you need. It returns a labelled floor plan you can open and refine in the CAD editor.
Sections and elevations.
Pick longitudinal, cross, or both. It projects the section, draws the slabs and roof, and annotates the heights.
Prefer cortes? Type that and it still works.
A construction budget, costed by m².
Give it the built area, the finish quality, and the region. It splits the trades, adds contingency, and totals the estimate.
Everything in one place
Everything in one place
Plans, cuts, design, and renders live in one architecture engine.
The studio
AI engineOne model. Plan, section, render — the same building.
This is the Alcántara building, reverse-engineered from its render into a real model. Rotate it, drop to the plan, cut the section, then press render — all in one window. No exporting between four programs.
3D model
Massing
3 storeys · drag to orbit
Every view here is the same building. The render is reverse-engineered back into a model and its drawing set, so the plan, section, and elevation stay true to it.

Geometry from the project's own plan and section. The DeepSeek engine drives this end-to-end as access opens.
The budget
AI engineDescribe the building. Get a costed budget.
Give the engine the built area, the finish quality, and the region, and it returns a full construction estimate — every trade priced, contingency and VAT added, the total broken down to the cost per square metre. Export it to a branded PDF or a live Excel sheet.

Real chapters and unit rates for a premium new-build, structured as a bill of quantities. The DeepSeek engine drives this end-to-end as access opens.
Made by the engine
AI engineRenders straight from the brief.
One prompt. A million outcomes.
Same engine, three different aesthetics. A Lisbon facade, a seafood restaurant interior, and a sculptural villa study come from the same brief loop. The image has to prove light, reflection, landscape, material, and architecture at once.
How it works
AI engineOne prompt in. A drawing set out.
Describe the building in plain words. The engine drafts, you tailor. No flags, no config screens.
FIG 01
Describe it.
Type a command and answer a few plain questions: building type, area, floors. The things you already know.
FIG 02
The engine drafts.
Plans, sections, the budget, and renders generate and stream into the terminal and the editor.
FIG 03
You tailor.
Open the result, adjust anything, then print or export. The engine does the heavy lifting.
Who it's for
AI engineFor studios, engineers, and developers. Anywhere.
Terraza is built for everyone who puts up buildings: architecture studios, engineering offices, and house developers, anywhere in the world. The engine does the drafting; the judgement stays yours.
Studios & engineers
Draft plans, sections, and details to a professional standard, in a fraction of the time.
Developers
Go from a brief to drawings, a costed budget, and renders before the first meeting.
A lite version, soon
A guided, plain-language mode so anyone can describe a home and watch it get drawn.
Honest status
Hover a word.
Terraza is in early access.
The drawings and budgets you see today are generated from a fast structured mock, so the full workflow already runs end to end. DeepSeek Pro v4 wiring is next.
