About this home
Single-level living at its best. A welcoming family room opens through French doors to a fully fenced, maturely landscaped backyard. Around the corner the home opens up: a spacious kitchen island anchoring dining and living in one bright, connected flow, two distinct living areas, room to spread out and room to host. Two-car garage plus an oversized driveway with rare additional space for a boat or RV. A SeaTac location that does the commuting: three minutes to downtown Des Moines and light rail, ten minutes to shopping in Burien and Southcenter.
