Energy-efficient refurbishment and extension

Munich-Schwabing

2017 - 2022

The residential house with a hipped roof, built in 1953 near the English Garden in Munich, was extended while occupied, energetically renovated, and given a new roof. At the request of the owner, the appearance of the existing building should be preserved.
Extension: The new cubical, single-story extension with basement naturally complements the residential house and generously expands the small-scale living space. Large glass surfaces to the east and west offer new views of the terrace and garden areas in front, and strengthen the connection between inside and outside. On top of the extension is a large, south-facing terrace, which is accessed through a newly created winter garden.
Roof expansion: In order to maintain as much living space as possible in the attic, the old, dilapidated hipped roof was completely removed. A concrete knee wall serves as a ring anchor for the new wooden roof structure. The visible, horizontal roof truss with softly shaped beams allows a single, pillar-free room. This room is divided by a small roof terrace in the west and a wide dormer as an opposite counterpart. The living area, sleeping niche, and an open kitchen are thus naturally zoned. Several roof windows additionally illuminate the open roof truss. Above the house entrance, a steel balcony serves as a protective roof and offers the possibility of creating a second access to the attic, which can be separated from the ground floor, via a future staircase.
Energy renovation: The existing facade of 30 cm pumice hollow blocks was energetically renovated and covered with a 14 cm thick mineral foam insulation. The smooth plaster surface appears lively due to a handmade plaster application. All windows were replaced with triple-glazed wooden windows with an aluminum shell. A thermal flat collector is installed on the new, highly insulated hipped roof.
Materials: High-quality materials were used: oak, copper, and Kirchheim shell limestone.
Both in the finishing trades and in the house technical installations, the owners contributed a high proportion of their own work.
