Higharc

Higharc is a Durham, North Carolina–based software company that builds an AI platform covering the homebuilding lifecycle from design through construction. The platform, marketed as the Homebuilding Cloud, lets builders draft plans with generative design, manage plan portfolios and options across communities, produce automatic material takeoffs, present buyers with configurable 3D sales experiences and output construction documents. Higharc states that changes to a plan or a buyer selection automatically propagate into lot-specific estimates, construction documents and marketing assets, keeping design, sales and construction teams working from the same data.

Technically, Higharc represents each home as a 3D spatial database that encodes geometry along with code requirements and construction standards, which the company says provides the structured data foundation needed for production-grade AI and addresses the spatial-reasoning failures it attributes to general AI systems. In 2026 the company extended the platform beyond builders to the building materials supply chain with an AI Estimating product for lumber and building materials distributors, built around an "AutoTranslate AI" capability that converts a 2D floorplan image into a 3D spatial data model and pairs proprietary vision models with deterministic construction logic to produce quantity takeoffs mapped to purchasable materials.

The company positions the product as a replacement for AutoCAD and assorted point solutions, and operates a 100% web-based platform hosted on AWS with a dedicated customer success organization. It is remote-first with 100+ employees and reports more than $170 million raised in total.
