Fyrtornet consists of four-storey buildings with two-storey penthouses recessed from the southern and eastern façades. The façades, finished in shades of white and grey, are complemented by darker details that give the buildings a distinct graphic character.
The property includes 65 rental apartments ranging from 1–4 rooms and kitchen, designed for space efficiency with open layouts and seamless transitions between indoor and outdoor areas. All apartments have a balcony or patio, and most enjoy lake views over Mälaren. The balconies feature clear glass and aluminium railings.
The ground floor houses a garage and storage units, easily accessible by lift. Facing the street are glazed stairwells, bike rooms, garage windows, and spaces for waste sorting and technical installations.
The green courtyard, located one level above street level, can be reached via lifts or stairs and provides areas for play, relaxation, and socialising. Small trees, raised planting areas, and hedged patios create a pleasant and child-friendly environment.
Fyrtornet was built as an Egenvärmehus, meaning it has extremely low energy consumption, partly achieved by recycling heat from ventilation air.
