Mixed housing in Cross Laminated Timber
Niels Pettersson Sandmark
Trekvart is a timber building in the truest sense: its skin is in untreated and dark-painted wood and its structure is made up of CNC-cut panels of massive timber, so called CLT. Thus, build time and CO2 emmissions can be kept to a minimum.
The task was to build on to Västervik's long tradition of building and working with wood while giving the city a modern landmark and much needed housing. Trekvart is "three quarters" of a block, where a closed and sober exterior contrasts with a light, bright and lively courtyard that opens up toward a beautiful grove of oaks and birches.
The three houses facing the courtyard are designed to build a sense of community among the inhabitants. In addition to their private apartments and balconies, all residents have access to shared terraces and interior spaces, such as a communal green house.
As we truly believe that a succesful community is a diverse one, Trekvart holds a great mix of apartment sizes - from simple studios to luxurious five room apartments. This encourages bonds and friendships to form outside of socio-economical or generational boundaries.
1. Conditions: The development rights are maximized in extent and height, forming an L-shaped volume with its corner facing the oak and birch grove.
2. Courtyard: To create distance to the grove
and free up space for a central and clear
defined courtyard, a block is subtracted from the L-shape.
3. Divide and connect: The remaining volume is divided into three parts. Narrow alleys connect the central courtyard to Stora Trädgårdsgatan and a new
4. Place-making: The volumes along Stora
Trädgårdsgatan are pushed and rotated to create new public spaces along the street.
5. Internal communication: Larger apartments are reached directly from stairwells, centrally located in each building. Small apartments are accessed via connecting entrance-balconies. Main entrances are placed towards the street and are complemented by courtyard entrances.
6. Sun and terraces: Some of the apartments in
the upper planes are removed to create good sun and
lighting conditions for the yard and apartments. 3 shared and and 5 private roof terraces take their place.
7. Community: All residents have access to
a bookable room and roof-top terrace on the top floor of their building. The residents also share a greenhouse as well as a generous laundry room with adjoining re-use and recycling room.
8. Trekvart: An open block is created - three corners framing a courtyard. The green and active courtyard embraces the fourth and most important corner: the grove! Hence the name Trekvart (three-quarters).
