Introducing Sierra, a luxury lakefront retreat by Custom Nest. Set along the calm waters of desirable Emerald Bay, this Lake Arrowhead home has been taken down to the studs, expanded with a new level, and thoughtfully rebuilt. Four ensuite bedrooms plus a bunk room, inviting gathering spaces, and an included single-slip dock create a home designed for time together at the lake. All-new windows, doors, plumbing, and HVAC complement a renovation defined by Custom Nest’s creative vision and attention to detail. Cathedral ceilings and expansive windows fill the open living spaces with natural light, framing views of the water and surrounding trees. A fireplace flanked by built-in niches of stacked firewood anchors the living room, while Roman clay, Concretta finishes, and a considered palette bring depth and warmth throughout. Designer lighting, including Palecek and custom pieces, gives each space its own character. The kitchen pairs premium Lilac marble with custom cabinetry, Blum hardware, a La Cornue French range, and JennAir appliances. A custom chandelier crafted in California hangs above, while a generous butler’s pantry with its own sink offers ample storage, preparation space, and a dedicated home for countertop appliances. A pass-through window with a granite counter connects the kitchen to the outdoors for easy summer entertaining. Large sliding doors open onto a new deck finished in premium TimberTech decking, extending the living and dining spaces into the trees above the bay. From morning coffee to dinner overlooking the water, the lake remains part of everyday life. The main-level primary suite offers a quiet retreat, with a marble bath featuring a freestanding soaking tub and glass-enclosed shower. A separate powder room serves the main living spaces. Throughout the home, richly veined marble and quartzite, along with tile from Mission Tile West, Zia, and WOW, reflect the care given to each bathroom. One level below, a family room with a wet bar creates a gathering place after a day on the water, accompanied by an additional full bath and an ensuite guest bedroom. The lowest level offers another ensuite bedroom and a charming bunk room, providing inviting accommodations for guests. A two-car garage with interior stairs into the home adds everyday convenience, while new concrete stairs lead to the lake trail and access to the single-slip dock. Beautifully designed and deeply connected to its setting, Sierra offers a life shaped by the lake.
