Abstract [en]

Developers and architects have limited possibilities to design and offer customized apartments. The use of conventional construction systems, with load-bearing walls in concrete and vertical HVAC shafts, tends to lead to standardized floor layouts, which are difficult to modify over time.

In this thesis, a timber structural system that promotes flexible housing is developed. The structural system allows free positioning of apartment dividing walls, independent plan layouts on each floor and free window positioning in the facades. The structural system is also designed so that renovation and remodeling of the building can be performed in an easy and efficient way, so that flexibility is maintained during the lifetime of the building.

The study focuses on the structural aspects of the building, but also includes assessments with regard to fire safety, acoustic properties and production.

Omniplan AB's project BoLag has been used as a case study. The project is a part of the building exhibition LinköpingsBo2017, and omniplan has high ambitions for this project to be at the forefront of innovation. Two main concepts are applied to the building: Flexibility and the use of a timber structural system. The shape of the building plot, regulations in the zoning plan and omniplans visions were used as preconditions in the work.

Modern timber structures normally use some level of prefabrication. Many suppliers of timber structural systems have developed their own building systems, more or less open. None of these standardized systems provides the flexibility that omniplans project demands. Therefore, a high level of planning is required.

The result shows that it is possible to apply a flexibility concept on residential buildings with a timber structural system. The objectives are reaches by utilizing a concept that is commonly used in office buildings, where flexibility often is crucial. A beam and post system of laminated timber eliminates the need for load-bearing walls, allowing for a plan layout that varies from floor to floor. A HVAC space in the floor slabs, instead of vertical shafts, facilitates free placement of bathrooms and kitchens.

Timber building technology is developing rapidly, and hopefully the specific properties of timber can be used to develop the housing industry in general. This study shows that the use of timber has potential for innovative construction.
