Proposal where main aim was to design a house which is surrounded by streets and neighbour . Concept was a concrete block which is monolith but here transformed with small concrete cubes with round holes which provides a intimacy for a residents. The main aim was to keep strong monolith appearance from outside where there is not on first look visible doors and windows and inside to provide maximum usable space with great amount of natural lights. Using almost all space as living it is also provided small green areas in form of patios where house is merged with nature. All inside work is hidden beneath cubes structure which can be applied on any kind of facades or fences. The dimension of one cube is 15x15x15cm and stacking them can be made any kind structure. House is made entirely of concrete which can be sustainable building material: resource efficiency, durability, thermal mass, reflectivity, ability to retain stormwater, minimal waste.
