Best 3D Floor Plan & Interactive Floor Plan Companies in St. Louis (2026)

Quick answer: For 3D floor plans in St. Louis, in-house teams use software like Cedreo, while developers who want done-for-you marketing and interactive floor plans hire a studio. Rendimension is a top pick, alongside providers serving St. Louis like STL 3D Tours, The 2D3D Floor Plan Company, The Render Cafe, RealSpace3D and 3DPlans.

For a St. Louis high-rise, loft or multifamily launch, the floor plan is a sales tool: buyers compare units, understand layouts and skyline or historic-district character, and choose a home, often before the building exists. A flat 2D plan does not sell the way a marketing-grade 3D floor plan or an interactive, clickable unit selector does, with section-view layouts produced for offering plans and broker sites. As elsewhere, the market splits into in-house software and done-for-you studios. This guide ranks the options for developer sales specifically.

How we ranked these

• Marketing fit. Sales-grade 3D and interactive plans, not just technical drawings.
• Interactivity. Clickable unit selection and floor-specific views for a sales site.
• Coverage. Residential, commercial and site or master plans.
• Campaign consistency. Plans modeled from the same files as renders and VR.
• Bilingual delivery. English and Spanish for the region's buyers.

How to choose for your St. Louis launch
