AI architecture that keeps dimensions honest

Sketch rough. Render true to scale.

Sketchdown solves the biggest failure in AI-generated architecture: wrong dimensions. Turn raw site photos and fast hand-drawn ideas into high-fidelity renders with real-world precision every time.

How Sketchdown works

From messy reality to architectural clarity

Raw aerial prospect image

Step 01

Upload raw site photos

Start with real aerial or on-site images, even if they contain snow, debris, shadows, or visual noise.

Automatically cleaned prospect image ready for planning

Step 02

Auto-clean the prospect

Sketchdown removes clutter and normalizes terrain so you can design on a clean, usable base.

Step 03

Sketch in true dimensions

Draw quick footprints and volumes in real scale. Example: place a "7m x 8m" garage exactly where it belongs.

Step 04

Generate high-fidelity renders

Convert massing into polished architectural visuals while preserving geometry, proportion, and site context.

Feature spotlight

Change only what you want. Keep the rest untouched.

Lock the parts that must stay fixed, edit only the selected area, and fade between versions to verify exactly what changed.

Smart selection makes it easy to lock down

Feature spotlight

Sketch freely. See results instantly.

Draw by hand and get immediate visual feedback. Sketchdown turns rough strokes into rendered concepts in seconds, so teams can iterate quickly and explore function and form without breaking momentum.

Why teams switch

Most AI tools guess scale. Sketchdown enforces it.

Generic image models hallucinate dimensions, which breaks downstream decisions. Sketchdown ties generation to measurable space so concepts stay buildable.

  • Dimension-aware generation: constrained by your actual measurements.
  • Site-first workflow: start from real photos, not blank canvases.
  • Fast iteration: explore design options without losing scale integrity.

We went from messy site snapshots to presentation-grade renders without rechecking dimensions every round.
