Lakewood Garden Mausoleum seeks to preserve the character of the historic landscape while creating dignified burial and commemoration space for as many as 10,000 people. With so much of the building program tucked into the hillside, considerable open space is conserved and visual impacts on the natural beauty of the surroundings were mitigated. Mature tree cover was preserved through air spading, root pruning and shoring with sheet piling. A new accessible green roof extends the open lawn of the surrounding cemetery with traditional benefits of carbon reduction, reduced cooling loads, generation of oxygen, heat-island reduction, and maximizing runoff infiltration. The building is oriented east-west to maximize solar exposure.
