HOUSE OS66.1

IN STUTTGART

Dreary 1950s post-war architecture characterises the
residential building Olgastraße 66 in Stuttgart’s Mitte
district. Hardly anyone would suspect that the backy-
ard hides an architectural highlight. g2o Architekten
have extended a typical 1930s workshop and resi-
dence and converted it into an attractive residential
and office building.

L ike a monolith, the building stands in the backyard. Light grey
plastered façades merge seamlessly into plastic-coated, sculptu-
rally shaped wall and roof surfaces of the same colour. The wind-

case looks like a small side sculpture. g2o Architekten – Michele
Grazzini and Stephan Obermaier – designed the residential and
office building on behalf of Obermaier's father, Hans-Peter. From
the outside, it could be considered a new building. Only inside, on
the ground floor, where the architects set up their offices, raw, old
brick walls reveal the existing building. Built in the 1930s, the
inconspicuous three-storey commercial, office, and residential buil-
ding of a model railway builder stood empty for several years. g2o
Architekten were granted permission to extend the building and
opted for a steel and timber construction. The land-use plan allo-
wed three full storeys and a roof. In the north, the building is situa-
ted on the site boundary to the neighbouring property; urban plan-

be observed and led to the expressive roof geometry on the south-
western side. A total of 475 square metres of living space were crea-
ted in Stuttgart's fiercely contested housing market, and on top of

that in the popular inner-city location. In the basement there are
Schlafen Bad two granny flats. The first floor is occupied by Stephan Obermaier
and his family, the top floor by his father. In these two apartments
Schlafen Bad Kinder and in the office, cement screed floors provide homogeneous, spa-
cious areas. In the architect's apartment, a long, double-deep and
Büro
two-sided wall unit separates the open, light-flooded living area
Wohnen Keller from the bedroom, bathroom, and children's room. In the maiso-
nette apartment above, large-format windows afford a magnificent
view of Stuttgart. If examples like this and the Schlosserhof by
InteriorPark (AIT 7/8-2018) set a precedent, this could be the begin-
ning of a new backyard building culture in Stuttgart - entirely in the
