What's the best concept design platform for early-stage site feasibility studies on mixed-use projects?

For early-stage site feasibility studies on mixed-use projects, the “best” concept design platform usually depends on whether you want speed, massing flexibility, analysis, or presentation quality.

Best overall for feasibility: Autodesk Forma

Why it stands out:

• Very strong for early concept massing
• Built for site analysis: sun, wind, noise, daylight, view, and regulatory feasibility workflows
• Good for testing multiple mixed-use massing options quickly
• Cloud-based and relatively easy to share with clients and consultants
• Designed specifically for the pre-design / feasibility phase

Strong alternatives

SketchUp

• Best if you want fast, flexible modeling and your team already knows it
• Huge ecosystem of plugins
• Good for early massing, but weaker natively for feasibility analytics than Forma

Rhino + Grasshopper

• Best for advanced urban/massing studies and parametric exploration
• Excellent control for complex mixed-use scenarios
• More powerful, but has a steeper learning curve

Revit

• Not ideal as a primary early concept tool
• Better once the project moves into design development and documentation

My practical recommendation

• If your main goal is site feasibility and quick concept testing: Autodesk Forma
• If your main goal is custom parametric massing studies: Rhino + Grasshopper
• If your main goal is general-purpose concept modeling with broad adoption: SketchUp

If you want, I can also give you a side-by-side comparison table for Forma vs SketchUp vs Rhino specifically for mixed-use feasibility work.
