The seven-story frame-constructed building offers 132 condominium homes. Penthouse level homes include a mezzanine level that opens to roof top decks. There are four separate roof-top viewing decks. Situated along a SR-99 exit ramp in downtown Seattle, the landscape for the Marselle Condominiums included streetscape planting for street improvements, residential scale planting for ground floor units and a signature landscape design for the main building entry and roof top courtyards. HBB integrated intensive and extensive green roof elements based on three microclimate zones due to sun and wind exposure and defined volumes of space with raised planters that delineate the the outdoor gathering areas and terraces.
