Best Implemented Project of Residential Estate

About the project
B73 is a residential building located in Sofia, Bulgaria. It stands out in the dense urban context with its innovative and impactful look. The building itself achieves a balance between design and functionality that work simultaneously, while having high-end material usage and exceptional quality in execution.
Each residential floor of B73 comprises of just a single apartment. Optimal spaces and light inflow are anchor points when designing the apartments, where the top floor one has a 6,4m high living room. Inside the double height lobby is set up a unique light installation 44.12 by Bocci.
B73 is one of the very few buildings in Bulgaria, that uses solid surface material and thermoforming technology for achieving complex 3D shapes. The concept of the façade starts from a simple white surface that has several strategically placed cuts and it’s stretched along the Z-axis. A discontinuation occurs between the floor slab and the stair’s landing, creating the shape of a swallow bird.
