20X20 – multifunctional student appartments

20×20 multi functional student apartments is a project that introduces the new standard of apartment blocks. Instead of using concrete this modern interpretation is made of wood that represents sustainable architecture and supports multiple possibilities of cohabitation.

To stop the climate change basic architecture must be transformed with adaptable sustainable concepts. Architecture must be taken to the next level. The multi functional student apartments uses typologies of classic buildings in the heart of New Delhi and adapts them to a modern approach. By reducing the concrete part of the building to a minimized core within the building, the amount of mineral materials needed is drastically reduced. This core is essential to make an exit during an emergency possible. The remaining 75 percent of the construction is made of a cross laminated timber (CLT) skeleton. This allows an easy assembly of the parts which can be performed without cranes or big construction machines.

20×20 multi functional student apartments adapts elements from classic Indian architecture to a modern approach. A surrounding pergola shields the apartments from solar radiation. It reduces the thermal impact onto the building and helps to keep the rooms cool. The overhanging ceiling of the pergola also shields the building from rain. This slows down the abrasion of the wood. So no chemical coating is needed to extend the lifespan of the construction wood.

The detailed CLT facade reflects traditional filigree works of Indian carpentry. It acts as a shield from solar radiation as well as a handrail. The variation of horizontal and vertical elements creates a vivid facade.

An adaptable CLT skeleton can form different kinds of apartment levels. Multiple layers of fiber plates protect the CLT skeleton from fire. The cavity in between the CLT beams is filled with loose mineral bulk or mineral wool filling. This provides a protection from noises from outside the rooms.

Walls are made up of multiple fiber plates which close the CLT skeleton. The cavities are also filled with mineral wool or bulk. The fiber plates on the outside are coated with cement plaster.
