Turnstone Custom Homes

What Turnstone Custom Homes does

Turnstone Custom Homes is a coastal Delaware design/build firm founded in 2004 by Harvey Ryan that constructs luxury custom homes and large-scale renovations for affluent homeowners and retirees in Sussex County beach communities including Rehoboth Beach, Lewes, Dewey Beach, Bethany Beach, and Fenwick Island. The company operates under the legal entity Turnstone Holdings LLC, with 15 full-time employees plus over 100 subcontract workers, completing 15-20 custom homes and renovations per year and more than 150 total since inception. Revenue is generated through project-based contracts, predominantly structured as Guaranteed Maximum Price (GMP) agreements, with typical custom homes in the $600K-$700K+ range and a separate kitchen and bath renovation offering launched in 2019.

The firm differentiates via a proprietary 500-step construction schedule template that embeds lessons learned from every prior project into a standardized process applied to each new build, supported by 180 years of collective project management experience across the team. An in-house design team produces stampable construction plans that, combined with the design/build model, eliminate the need for separate architects on most projects. An online construction management portal delivers 24/7 transparency to clients — particularly remote, out-of-state homeowners — integrating schedule updates, selections, photos, change orders, and budget tracking. Specialized coastal capabilities include Insulated Concrete Forms (ICF) construction, hurricane-rated framing, flood-zone compliance, and aging-in-place design features.

The go-to-market is high-touch enterprise field sales beginning with a free on-site feasibility assessment frequently conducted personally by founder Harvey Ryan, supported by a formal Realtor Referral Program described as the "lifeblood" of the pipeline. Marketing combines organic SEO/content (an extensive blog), paid acquisition (Google Ads targeting Lewes kitchen/bath keywords, Facebook), platform presence (Houzz, 59+ reviews; Google, 56+ reviews), and earned media (Delaware Today, Cape Gazette, Home Builder Digest). Pricing is project-specific with a summer 2025 promotion of 10% off custom cabinets for kitchen and bath renovations. Awards include Delaware Custom Home Builder of the Year (2022) and Best of Houzz Service nine times, with consecutive recognition from 2022 through 2026.
