Nineteenth century house overlook a beautifull garden in a courtyard of a city block in diplomatic district of Bratislava. By replacing the existing roof with a new, minimalistic addition we create space for a new flat. The existing internal vertical core is replaced by a new staircase with elevator. It allowesus to “clear” the disposition of the “old house”. The new vertical core is made by concretre and it is also becaming the new entrance. The dominant feature of the house will remain the reconstructed wooden winter garden on the south facade.
