SOLIS is currently the largest Passive House multifamily building in Washington. It achieves dramatic reductions in energy use – 50% below the US multi-family median – at a mere 5% cost premium. This was done through the use of conventional materials in innovative ways including pairing an enhanced building enclosure with a top-notch mechanical system for exceptionally comfortable and healthy units. Lush landscaping, gorgeous materials, elegant details and the cleanest indoor air possible make SOLIS the pinnacle of eco-luxury living.

Designed by Weber Thompson, the sophisticated design is based on Passive House principles which reduce energy use, reduce operational costs, and prioritize resident health and wellness. Lush landscaping extends into an open-air residential lobby and exterior feature stair, creating an indoor/outdoor experience and reducing heating/cooling loads. On the roof is an extensively landscaped deck with panoramic views of the Seattle skyline and Mt. Rainier. Continuous filtered fresh air, healthy materials, zero air transfer between units, and individual unit heat pumps make SOLIS one of the healthiest urban living option on the market alongside Pax Futura.

Connecting to Capitol Hill’s culture and identity was paramount. A patterned screened “jewelbox” strikingly marks the building’s open-air entry court, creating a welcoming indoor/outdoor restaurant space. Additional boutique retail spaces are shielded by canopies with integrated solar panels that offer weather protection and dappled sidewalk shade. An iconic mural – “Amaterasu” by the UK muralist Fin DAC – celebrates the neighborhood’s artistic roots.

The project was developed by Solterra.
