Metro Denver Luxury Homes For Sale

Property Description

A stunning modern estate where elevated design and breathtaking views meet on 4.58 acres that’s extremely private yet convenient for everything! Hidden in a small pocket of upscale custom homes and bordering open space on two sides, the property offers unprecedented privacy that’s truly hard to come by! Framed with jaw-dropping views of mountains, European and handcrafted cabinets and an astonishing large lagoon scene island, the chef’s kitchen brings function and ambience of a star restaurant right to the home! Patio and deck on East & West, ample space awaits outdoor dining, bird watching & splendid sunsets! The 800+ SF primary is a luxury private retreat with unobstructed mountain & lake views, sitting room, curb-less shower and spa bath. Views in every room, nature inspired design – floating vanity top crafted from old tree, delightful wine room, custom lighting – illuminates the space with an organic, modern and playful vibe. The home is built of insulated concrete form (ICF) which is rare but increasingly sought after in custom builds where comfort, energy efficiency, disaster resistance, and long-term value matter. The property is living proof of superior fire resistance surviving the Marshall Fire which destroyed 1,000+ homes. Expanded and redesigned, almost everything has been updated including HVAC and septic. Dreaming of a homestead? It’s done for you: asparagus, fruit trees & pollinator gardens meander through the land. Agricultural zoning, horses/animals are permitted by right. 600+ SF bonus space not included in the listing size – with great Southern exposure and used as a studio and storage currently – ready for your touch to next level luxury: conceptual digital rendering of a wellness spa is available. Biking path at doorstep, hiking, shopping and downtown Boulder and Louisville are just 3-10 mins away. Welcome home, city dwellers and nature lovers!
