What Clarum Homes does

Clarum Homes is a privately held, founder-owned design-build and general contracting firm founded in 1994 and headquartered at 550 College Avenue, Palo Alto, California. The company constructs and extensively renovates custom luxury homes for high-net-worth homeowners and a recurring set of architectural partner firms (including CKA Architects, Zaharias Design, EID Architects, Feldman Architecture, DAHLIN, and DeWitt Design Studio) across the California Peninsula — Palo Alto, Los Altos, Menlo Park, Atherton, and Woodside. Its portfolio spans architectural styles such as Modern Farmhouse, Mid-Century Modern, Warm Modern, and Spanish Revival Mission.

The company's core technical differentiator is high-performance sustainable construction. Homes are built to Passive House (PHIUS) standards with LEED Gold/Platinum and EnergyStar credentials, using structural insulated panels (7-inch SIPs with 2 inches of exterior XPS), heat recovery ventilation on every floor, advanced thermal envelopes that exceed California code, and all-electric systems (induction, electric HVAC, solar) aligned with California's all-electric building direction. Construction processes are managed through a cloud-based client portal (Procore) that delivers real-time schedules, daily progress updates, photos, and documentation directly to homeowners.

Business model is project-based, quote-based, and one-time per engagement: revenue is generated through design-build and general contracting fees tied to the construction or renovation of individual luxury custom homes. Customer acquisition is relationship-driven, with Marek Loder (Director of Business Development) handling direct engagement with prospective homeowners, supplemented by a project-showcase website and referral flow through architectural partners. No external funding, institutional investors, parent company, or distribution/reseller network is disclosed; the company operates as an 11-50 employee independent contractor serving an exclusively regional, high-end residential niche.
