Dutch studio BaksvanWengerden has added a splayed concrete extension to a triangular brick house in north Holland (+ slideshow).
The single-storey extension projects from the rear of the 1930s house and is slightly more tapered on one side to create a subtly asymmetric shape.
Describing their decision to use concrete for the extension, architect Gijs Baks explained that its "robust and solid appearance" made it "a good match" for the brickwork of the existing house.
The architects also removed partition walls inside the building, creating an open-plan ground floor that opens out to the garden.
A new wooden staircase is boxed into the centre of the living room and leads to two more floors.

Here's some more information from BaksvanWengerden:
In the dune landscape of Bentveld, a villa park village between Haarlem and the North Sea coast, BaksvanWengerden Architecten is commissioned to renovate and enlarge a single-family house.
Ground floor plan
The house, built in 1932, was one of the first in the area. In the Zeitgeist of its era, the internal organisation was derived from the concept of separation of functions. This made the house feel small. The house appears as a prototype, with its long rooflines, overhanging roof eaves and solid materialization.
First floor plan
BaksvanWengerden developed a design which maximises the sense of generosity throughout the house. The open plan ground floor extends into the lush garden. Like a backbone, the new staircase binds all the functions within the house. The extension manifests itself simultaneously as a connecting as well as a contrasting entity. Its abstract, concrete materialisation and detailing emphasizes this ambiguity.
