Finch 3D
Graph-based AI that generates optimized floor plans and massing from a building envelope in seconds.
About
Finch 3D is a generative design platform for the earliest phases of architecture, from first sketch through schematic design. Rather than image generation, it uses graph technology and constraint-based AI: architects define a site boundary, program, unit mix, circulation requirements, and zoning rules, and Finch populates building massing with floor plan layouts that satisfy those constraints, exploring thousands of permutations in seconds. It returns instant performance feedback on unit distribution, daylight, carbon footprint, and error detection against firm, customer, and municipal rules.
The Malmo, Sweden-based company was founded by architects Pamela Nunez Wallgren, Jesper Wallgren, and Martin Kretz, spinning out of their studio Wallgren Arkitekter after an internal Rhino plugin gained traction. Today it runs as a cloud application with two-way native integrations into Rhino, Grasshopper, and Revit, targeting multifamily residential, mixed-use, and commercial projects. It offers a free tier where exports are locked and paid plans from around 49 euros per month. Reviewers note it is a genuine constraint-satisfaction engine rather than a prompting tool, strongest on repetitive residential schemes where fast layout permutation is valuable.
What it can do
- Graph-based generative floor plan filling from building massing
- Constraint-driven layout exploration with thousands of permutations
- Instant feedback on unit mix, daylight, carbon footprint, and area distribution
- Error detection against zoning, firm, and municipal rules
- Two-way native integration with Revit, Rhino, and Grasshopper
- Browser-based interactive 3D model sharing and reusable organization libraries
Setup
Sign up at finch3d.com; define site boundaries, program, and rules in the live demo or a new project, then generate layout iterations and export geometry.
Prerequisites
A Finch account; site boundary and program requirements defined upfront for best results.
Use cases
Works with
Trust score — 7/10
Scored 7/10 (metrics tier, metrics-v1). Evidence: Malmo-based company founded by practicing architects; operates as cloud platform with two-way Revit, Rhino, and Grasshopper integrations; freemium pricing from ~49 EUR/mo with a usable free tier. Strengths: genuine constraint-satisfaction engine rather than image generation, instant performance analytics, strong fit for multifamily feasibility studies. Docked for: (1) parametric rule-based system, not natural-language prompting; (2) limited independent review footprint; (3) no offline capability and export locked behind paid tiers. License: proprietary.
