What CustomSmart Homes does

CustomSmart Homes & Solar is a privately held, family-owned custom home builder founded in 2008 by Bill Lizzio Sr. (President) and Bill Lizzio Jr. (Vice President), headquartered in Piney Flats, Tennessee, and serving residential customers across seven Tennessee counties (Washington, Sullivan, Hawkins, Carter, Unicoi, Johnson, Greene) and three Virginia counties (Washington, Scott, Smyth). The company constructs custom modular homes in a climate-controlled factory at approximately 75% completion for on-site assembly via crane, alongside traditional stick-built custom homes, with floor plans ranging from 840 sq ft cabins to 10,000+ sq ft designs. Modular modules use 30% more lumber than site-built equivalents and pass 300 quality inspections.

The firm operates an integrated business model built around three pillars: (1) custom home construction priced at $150–$200 per sq ft with a five-step process from design through set day and on-site finishing; (2) a dedicated Solar & Energy Division established in 2011 that designs and installs residential and commercial solar arrays, battery storage with hybrid inverter technology, and Briggs & Stratton standby generators (13kW–26kW), with Bill Lizzio Sr. holding the NABCEP Certified PV Installation Professional credential earned in 2017; and (3) ancillary services including design services ($0–$2,000 fees), home improvements and remodeling, land sales across two subdivisions, spec homes in White Top Meadows, and a wholesale program distributing modules to builders and owner-builders. The company also brokers a network of five regional construction lenders plus Nelnet Bank consumer financing delivered through the Buildertrend platform.

Customer acquisition is direct-to-consumer and sales-led, driven by website inquiries, phone leads, model-home appointments, Google Reviews, and referrals; the company has completed over 200 custom homes since founding. Distribution is purely regional — no public API, no third-party resellers, and no software platform beyond the Buildertrend project management integration. The firm is privately held with no disclosed institutional investors, parent company, or external funding rounds, and revenue is not publicly disclosed.

• D.R. Horton: Largest U.S. homebuilder by volume, with for-sale single-family and townhome construction across most metros. Comparable at the new residential construction category, though serving a much broader and lower-price-point segment than CustomSmart.

Emerging players
