The Kopaszi Gát project is Budapest’s largest residential and office building development in the late 2010’s and 20’s. We won the first two residential buildings’ (BRA and BRC buildings – 260 apartments in total) design in 2016 on a competition. The installation plan of the site was prepared according to a unique and of a high standard concept, which was made by Adept, a Danish architectural firm. The eventual outcome of the mass was established according to the best solar access factors, the appropriate airspace ratios and optimizing the best views. The inner court is on an increased level in the BRA building and is surrounded by the building mass frame. This frame was cut in three, disengaging the mass and optimizing the court’s airspace ratio lead to maximum visibility in all directions and valorized the apartments positioned towards the inner court. The BRC building mass is made up of two, F+6 and F+14 floor towers and the F+3 floor intersection of the two. Considering that the BRC building is seated by the bay it is somewhat constructed in a higher demand in terms of the apartments and material usage as opposed to the BRA building. While the BRA building is made up of mostly 1-1 1/2 room apartments, the BRC building has 2-4 room apartments with penthouses designed on the emphasized top floors. When composing the facades of the building, it was important to connect and separate each mass with the planned materials and colour tone differences. The applied surfaces, materials and technical details were revised by the client and the constructor -due to market conditions- in many aspects during the construction process, as opposed to the construction plans. Hopefully all in all, the building will appropriately preserve the quality and character of our architectural intention.
