Marin rarely builds new.
Legacy is the exception.
Most buyers looking for a home in Marin are choosing between an older resale, a full remodel, or a custom build that takes years. Legacy at Lucas Valley offers something the market almost never does: a modern, move-in ready home, built new, in a quiet valley setting, ready for the life you want to live in it.
Twenty-eight new homes sit along Erin Drive and Erin Court, surrounded by the open hills of Lucas Valley. Each one is designed for space, privacy, and livability, with four to six bedroom options, generous indoor-outdoor living, and a separate-entry ADU included in every plan.
This is new construction made straightforward and easy - guided from homesite selection through move-in by a homebuilder who has done it many times before.
Designed for space, built for flexibility.
Legacy homes range from approximately 3,081 to 3,769 square feet across five distinct floor plans. Every home includes four to six bedrooms with a two-car garage, private outdoor living, and a first-floor ADU with its own separate entrance.
Inside, the homes are open and light, with chef-inspired kitchens, spa-like primary suites, and finishes you can personalize through Haven's design studio partners. Select plans include lofts, offices, flex rooms, optional bedrooms and baths, and an optional elevator, so the home can shift as your life does.
Two floors, a second-floor terrace, and a first-floor ADU. The optional elevator makes this plan a strong fit for single-level living.

Legacy interiors are open, light, and built around the way people actually live. Kitchens are the center of the home, with Thermador appliances, quartz countertops, soft-close Shaker cabinetry, and Kohler fixtures. Primary suites are calm and spacious, with freestanding tubs, frameless glass showers, quartz vanities, and designer Daltile tile along with spacious walk-in-closets.
Through Haven's partnership with HomeSite Services Design Studio, you can personalize the details that make a house feel like yours: cabinetry, countertops, hardwood flooring, tile, backsplash, and appliance packages, guided by a team that does this every day.*

The amenity is the setting.
Legacy’s community sits among the rolling hills and open space of Lucas Valley, with trails, parks, and panoramic valley views close at hand. A peaceful and calm setting within minutes of all the conveniences of Marin County.
A morning might start with coffee on the deck and a walk through the nearby Lucas Valley Nature Preserve. Weekends fill with hikes on Big Rock Trail, bike rides through open space, farmers markets, and easy drives to San Rafael, Larkspur, Sausalito, Sonoma, and San Francisco. At home, open kitchens, wide living spaces, and private decks and patios make it simple to host, gather, or give guests room of their own.
Quiet, connected, and unmistakably Marin.
Lucas Valley is one of Marin's calmer corners: residential, private, and surrounded by open space, yet still close to everything that makes the Bay Area work. Rolling hills and the Lucas Valley Nature Preserve sit at the doorstep. Highway 101 and downtown San Rafael are a short drive. San Francisco is about twenty miles south.
It is a place known for its trails, its top-rated schools, and a pace that feels a step removed from the rush, without giving up access to it.
Built by Haven Development.
