The town houses are a part of a large urban development project to transform a former industrial area on the harbour of Stockholm into the city's new high-profile environmental area called Norra Djurgaardsstaden.The houses, 18 in total, will be neighbouring a former gasworks, which will be turned into a cultural centre, as well as Husarviken, which flows into the archipelago, and the Stockholm National City Park. The architecture is inspired by the gasworks’ red bricks and simple geometry as well as by the area's green qualities. The aim of the housing district is to adapt to global climate changes, so that in 2030 the district will no longer make use of fossil fuels. The requirement in the building program is that energy consumption of the living units must not exceed 55 kWh/m²/year, including a maximum of 15 kWh/ m²/year used for electricity.The energy consumption will be minimized by means of the massing of the buildings, for example, the town houses are staggered in order to maximize views and daylight and have dense constructions. Also contributing are solutions such as intelligent lighting, solar panels for heating, and heat recovery.Characteristic for the town houses will also be green roofs with e.g. wild honeysuckle and herbs, which - along with a landscaped pond in the common yard - will collect rainwater, convert CO2, and provide a fertile ground for biodiversity. The sustainable approach is continuous throughout the building life cycle - from construction phase to operational phase and a possible later decomposition phase, i.e. Cradle to Cradle Design.
