Sweet Home 3D
Free interior design application for drawing house plans in 2D and 3D.

The intelligent homebuilding platform for automated design, sales, and construction.

Higharc is a cloud-native generative design platform specifically engineered for the production homebuilding industry. By 2026, it has solidified its position as the primary operating system for homebuilders by replacing fragmented CAD/BIM workflows with a unified data-centric engine. Unlike traditional CAD software, Higharc uses a parametric logic engine that automatically generates full construction documents, 3D sales walkthroughs, and precise material takeoffs from a single source of truth. The platform addresses the critical 'options' problem in homebuilding, where every floor plan variation previously required manual drafting. Higharc automates the generation of lot-specific plans and ensures that sales-configured options are structurally sound and cost-accounted in real-time. Architecturally, it utilizes a proprietary cloud-rendering and geometry engine that enables seamless web-based collaboration without the need for high-end local workstations. In the 2026 market, Higharc is the leader in reducing cycle times for builders, directly integrating with ERP and purchasing systems to minimize waste and manual error in the pre-construction phase.
