Architect in Duvall, WA — Piper Cole Architects

Duvall is a small city on the Snoqualmie River northeast of Redmond, occupying the transition zone between the Eastside’s suburban density and the rural Cascade foothills. With a charming historic downtown on Main Street, significant equestrian and agricultural heritage in the surrounding valley, and growing residential development attracted by its schools and rural character, Duvall draws homeowners who want more land, more privacy, and more connection to the natural landscape than the inner Eastside allows. Piper Cole Architects serves Duvall clients with custom home and renovation architecture services.

Duvall Architecture Services

Rural and Estate Homes

The Snoqualmie Valley around Duvall offers agricultural parcels, horse properties, and rural residential lots ranging from 2 to 20+ acres — a scale of site that simply does not exist in Kirkland or Bellevue. Estate homes on these properties can be designed with the generosity of siting that large parcels allow: positioning for Cascade views, locating accessory structures to create functional farm compounds, and integrating architecture with landscape at a scale that only rural properties support.

Custom Homes in Duvall

Duvall’s residential growth has brought newer subdivisions to the hills above the valley with custom home lots and view opportunities. We design custom homes appropriate to both the valley setting and the hillside neighborhoods — homes that are connected to the agricultural landscape and the mountain backdrop rather than importing a generic suburban design to a remarkable site.

Barn, Shop, and Accessory Structures

Agricultural properties around Duvall commonly have programs that extend well beyond the primary residence: horse barns, equipment shops, hay storage, guest houses, and caretaker quarters. We design accessory structures as parts of a coherent architectural whole — not afterthoughts — using materials and forms that are consistent with the primary home and appropriate to the rural agricultural setting.

Historic Downtown Duvall

Main Street Duvall has a small but active commercial core with historic buildings that benefit from thoughtful renovation. Commercial renovation projects in downtown Duvall are subject to City of Duvall design standards. We design commercial renovations that preserve the historic character of Main Street while meeting modern code and functional requirements.
