Reimagined 5-Bed Home + Finished ADU on 0.67 Acre, Minutes to Olde Town
This is a rare Arvada offering: a high-caliber, from-the-studs reimagining on two combined parcels totaling just over 29,000 SF — all within minutes of Olde Town Arvada. The main residence (approx. 5,173 SF) balances contemporary finishes with thoughtful livability: a waterfall-edge quartzite island anchors a chef-ready kitchen with a six-burner gas range, double ovens, KitchenAid refrigeration and integrated Avallon beverage fridge. Multiple living areas frame a tiled fireplace and open through panoramic doors to an expansive deck with sweeping city and mountain views.
The primary suite is a private wing behind a custom feature wall, complete with a fireplace, intimate seating area, private balcony and a spa-like ensuite offering dual vanities, steam shower, soaking tub and LED-lit vanity plus an ample walk-in closet. Two additional bedrooms on the main level share a well-appointed bath; the lower level expands living with a rec room and wet bar, two more bedrooms, a full bath and convenient laundry.
A fully finished ADU on the property elevates flexibility and income potential: panoramic doors, a dedicated wet bar, gym/studio space, a 3/4 bath, and a two-car garage create an attractive rental or long-term guest suite. Parking is abundant — four garage spaces reported (including ADU garage), gated driveway, tandem concrete pad and dedicated RV parking.
Outside, irrigated landscaped greenspace and a covered patio beneath a KE retractable pergola deliver low-maintenance entertaining options and year-round enjoyment. Located steps from Olde Town’s shops, restaurants and the G-Line light rail, this property blends privacy, scale and immediate access to regional trails and commuter routes. Finished to an elevated standard and sited on an unusually large lot for the area, this home is a standout opportunity for buyers seeking turnkey luxury and optional income generation.

A factual market snapshot around 8320 W 66th Ave.
Homes in the Olde Town Arvada corridor continue to outperform broader suburban averages due to walkable amenities and light-rail access. The market for premium, renovated single-family homes with detached or attached ADUs remains competitive; inventory for large-lot, high-finish homes is limited. Expect buyer interest from both local move-up buyers and Denver commuters seeking more outside space. Median sales in desirable Arvada pockets have shown modest annual appreciation (~3–6% range recently) while five-year appreciation remains healthy. For an asset of this scale, the ADU and mountain-view deck justify a premium to typical single-family comparables — verify comparable sales during offer preparation to support pricing and appraisal outcomes.
Likely single-family residential zoning (R-1 or comparable); property contains two combined parcels and an ADU—verify with city planning.
