North Bay Residence by Prentiss Architects is a 2,800-square-foot home on San Juan Island designed around its challenging natural setting. Rather than removing three mature trees, the architects shaped the compact plan around them, using a continuous stone wall to provide privacy from the road and organize the interior. A contrasting glass pavilion opens the main living spaces toward Griffin Bay, combining timber, steel, stone, and slate to create a balance between protection, durability, natural light, and strong visual connections to the surrounding landscape.

Set on a restricted site overlooking Griffin Bay on San Juan Island,
North Bay Residence was shaped by the challenge of preserving its natural surroundings.
Three mature, old-growth trees occupied the most practical building area,
so the architects chose to keep them, compressing the house and positioning
it tightly within the site's setbacks. The nearby county road also influenced the design,
requiring a careful balance between privacy, views, and connection to the landscape.
The house is organized around a continuous stone wall that begins at the parking area,
guides visitors to the entrance, passes through the interior, and extends beyond the house.
It creates a strong boundary from the road while organizing the spaces around it.
Living areas and the master suite face Griffin Bay while more enclosed rooms are placed toward
the hillside, creating a clear transition between protected and open spaces within the 2,800
square foot plan. A lighter glass pavilion contrasts with the stone wall and becomes
the main living zone. Glazed surfaces capture views and daylight from multiple directions,
while steel framing and heavy timber elements support the transparent volume.
Sliding and large glass openings strengthen the connection between the interior and the
surrounding landscape, creating a balance between solid, protective spaces and open
areas facing the bay. The material palette reinforces this contrast with glass, steel,
heavy timber, stone, and slate flooring, complemented by concrete panel chimneys
that anchor the pavilion. Durable steel frame windows and powder-coated exterior sheathing
respond to the island's exposed climate. Ultimately, the design shows how site restrictions
can become architectural opportunities, preserving trees, controlling privacy,
framing views, and creating a strong relationship between the house and its landscape.
