Reinventing a Classic Mid-Century Home for Comfort, Health & Vitality
The Retro Rambler is a high-performance, all-electric reinvention of a 1950s classic home—set in the heart of walkable, family-friendly Kensington, Maryland. With completion slated for Summer 2025, this visionary project will showcase the future of residential living: sustainability, health, and smart design in perfect harmony.

Expanded. Electrified. Elevated.
Reimagined from the ground up, the Retro Rambler features over 3,000 square feet of thoughtfully designed living space. A new 3-level rear addition includes a gourmet kitchen, spacious second-floor primary suite, private in-law suite, and a garden gym or office in the converted shed. The generous front porch and basement living area create room to relax, work, and entertain in style.
Electrify + Fortify for the Future
Every system has been upgraded for 21st-century living. The home is fully electrified—no gas appliances—powered by high-efficiency heat pumps, solar-ready infrastructure, and an EV charger. It’s not just smart—it’s strong. With insulation and air sealing that exceed code requirements, expansive Energy Star windows, and sustainable materials throughout, this home is fortified for comfort, efficiency, and resilience.
