In 2013 we were given the task to develop an investment plan for a ten unit apartment building in the fifteenth district of Vienna. Making it not only more energy efficient, but also increasing livability for its renters were goals of our client. Given that the north of this building faces a street with few trees and relatively high vehicular traffic, we initially explored various ways by which to green its facade. The rear of the building has a beautiful southern exposure for which we proposed adding large (approx. 75 - 100 sf) balconies to each of the apartments, which both shade the apartments from direct heat-gain in the ever hotter summers in Vienna, and increase the living space for the units. The balconies are constructed of exposed pre-cast concrete panels, with galvanized steel railings. New triple-glazed windows with black frames as well as the painting of original building details and a contrasting white facade gave the building a new, fresh look, highlighting its 1930's flair, whilst upgrading its energy efficiency along with added insulation on both exposed facades and a new roof. We developed a new color-palette for the public hallways and re-conceived both the interior and exterior public lighting. We worked with local architects AAP Architekten who assisted us with the securing of permits as well as construction administration on site.
The addition and renovation were completed in December 2015.
