The project is one of the biggest housing developments in Ljubljana, consisting of 4 housing blocks with 640 apartments and underground garage with 1200 parking spaces. The urban plane required 4 block-long strips of apartments (app.140 m long each) each with 4 floors and penthouse apartments on the top floor (42 units). The apartments are sold under government subsidy so the cost of the construction had to be under 700 EUR per apartment. Each features an open balcony and 'winter loggia' enclosed with glass. The building is also energy efficient and uses passive solar in the stairwells.
