On a private lakefront acre at the highest vantage point in Broomfield's most prestigious gated enclave, 1820 Mallard Drive is a residence of rare distinction where architectural brilliance, natural grandeur and refined comfort converge in flawless harmony. With panoramic views of the Rocky Mountains and a shimmering private lake as its ever-changing backdrop, this 11,000 square foot estate is a triumph of design and lifestyle, curated for the discerning few. A tree-canopied approach winds past still waters arriving at a circular drive, sweeping archways and grand portico that rises like a timeless sculpture from the verdant landscape. Every artisan detail from the grand gallery hall and soaring timber-beamed ceilings to the hand-chiseled stone and luminous lighting has been conceived to evoke awe and inspiration. The reimagined William Ohs kitchen is a culinary celebration of form and function, wrapped in Taj Mahal quartzite and bespoke walnut cabinetry, anchored by a chef's suite of Sub-Zero and Wolf appliances. Impressing with 22-foot ceilings and a monumental stone fireplace, the great room invites both intimate gatherings and grand entertaining. Walls of glass slide away to reveal heated terraces with fireplaces and unforgettable views. The main level primary suite is a private haven of indulgence, with a lake-facing soaking tub, dual water closets, steam shower, morning bar and couture-worthy dressing rooms. Upstairs, two luxe suites enjoy their own vistas, while the third-floor Sky Loft offers a 270 panorama perfect for creativity and reflection. The walk-out lower level is a destination in itself with billiards and media lounges, a stunning bar, spa room, private gym, and guest quarters. Beyond, layered patios and terraces, a putting green and private dock invite outdoor living in all seasons. With seven garage bays, Savant smart home integration and a setting that bridges Boulder and Denver, this is not merely a residence, it's a legacy of artful living.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
