This Victory Heights rambler sits well back from the street, on a flat, private lot where a wooded ravine forms the back edge and mature trees filter the light all day. Sunny corners for morning coffee, shaded ones for late afternoon, and a quiet you notice the moment you step outside. Nearly a decade of thoughtful, documented work shows in every room. Bamboo floors run throughout. The primary suite carries a vaulted ceiling, heated floors underfoot, and a calm, bright spa bath with a rain shower, soaking tub, and tile work done right. Windows and doors replaced, attic and crawl spaces insulated, new furnace with enhanced filtration, on demand hot water, whole house generator wired in. Nothing here was deferred. Outside is where it opens up. A covered patio extends the season for grilling and gathering, with separate zones for working and for sitting still. Raised garden beds, pavers, pea gravel paths, and turf mean weekends are spent enjoying the yard instead of fighting it. An insulated, powered greenhouse waits for the gardener. The detached cottage out back has its own entrance, kitchenette, full bath, and loft, a private second space that works as a guest suite, a home office, a studio, or a place for extended family close by but on their own. Meadowbrook Community Center with its pool and tennis courts sits minutes away, along with schools, bus lines, shops, restaurants, and the Lake City Farmers Market. Close to everything and quiet enough to hear the trees.

Please see Virtual Tour #1***THIS IS A PROPERTY BEING SOLD TO APARTMENT/CONDO DEVELOPERS***In Seattle’s zoning code, for Lowrise 2 (LR2) with an M designation, there is a Mandatory Housing Affordability (MHA) overlay. This MHA program allows developers to achieve extra floor area (which can translate to more units) if they either provide affordable housing on-site or pay into the city’s affordable housing fund. Thus, by complying with the MHA requirements, a developer can gain added capacity (height, floor area) and potentially increase the number of units. Specific limits depend on lot size and other code factors. In Seattle's LR2-M zone, the exact height and floor area increase from the M designation depending on the city’s specific MHA tables. Typically, the M designation grants an extra 10 feet of height (e.g., from 40 feet to 50 feet). Floor area ratio (FAR) also increases—often by around 0.5 FAR. On a 4,500 sq ft lot, if the base FAR was, say, 1.2 (allowing 5,400 sq ft of building), an M increase to 1.7 FAR could allow about 7,650 sq ft total. Always confirm with the current city tables, as specifics can vary. This is a guestimate from the Broker and everything needs to be verified Property built before 1978 thus we are warning of Lead Paint (see disclosure phamplet in supplements) IF YOU ARE PLANNING TO DEVELOPE THIS SITE YOU WILL RENTAL INCOME WITH A LITTLE WORK TO SUPPLEMENT THE DEVELOPEMENT COSTS.
