Solid Timber Construction – First Prize, Competition – "wienwood 15" Prize for Outstanding Wooden Buildings, "gebaut 2013"

One of the few multi-story wooden residential buildings to be built in Vienna was designed by P.GOOD architects. The project, on the theme “GenerationenWohnenRodaun”, was completed at the end of June 2013. The design made it possible to orient all the apartments in the direction of the east-west green space. The apartments are accessed via a gallery, which effectively protects them from the noise of the street.

The goal was to meet all the needs of sustainable building and living in the city – in social, environmental and economic terms.

Starting Points

1) Use of wood as primary building material
2) Location of the construction site at the intersection of two busy roads with high CO2 emissions
3) Existing green space with distinctive topography and a beautiful stock of trees
4) Urban structure of the area - a mix of council housing estates and single-family homes

It was possible to arrange the two structures so that all the apartments would be oriented in an east-west direction and optimally exposed to the green space. The site is also extremely resident-friendly in terms of open public spaces.
With its strong reference to green space and natural character with mature trees, it encourages physical activity and provides an attractive meeting point and recreational area for all ages.
With the goal of orienting all the apartments toward the green space while optimizing the timber construction, the structures were designed with a gallery access as well as a consistent planning grid.
Access via a gallery effectively develops the site and protects the apartments from the noise of the street.
The planning grid allows for a flexible range of apartment types and sizes.
In addition to the support structure, the theme of wooden construction is followed on the outer surfaces in the form of wooden balconies and contrasting larch wood and white plastered facades.

Social Sustainability

1) Integration of different generations and lifestyles
2) Accommodation of important functions that were housed in the former council estate, such as the seniors' club
3) Flexibility of floor plans

Concept of Supporting Structure

1) Wall system in laminated wood planks and wood frame construction
2) Ceiling system in laminated wood planks
3) Structural bracing in combination with the mineral stairwell cores
4) Basement in mineral construction

Wooden Wall Design - For vertical load transfer and horizontal bracing

• Basic ground floor walls and first floor walls finished in laminated wood
• External attic walls made using wood frame construction
• Laminated wood installed as large-format panels with 3 to 5-layered structure
• Fire protection and sound insulation through a combination of laminated wood wall with a plasterboard panels as planking

Ceiling Support System in Laminated Wood

• To make the wooden structure appreciable for residents, ceiling soffits were rendered visible through the use of a heavy, unbound fill
• The laminated wood ceiling has spans of 3.1 to 5.2m, while 5-layer ceiling thicknesses are between 162mm and 202mm

Principle of Horizontal Bracing

• Standard system: horizontal stiffening shear walls in laminated wood
• Shear-resistant ceiling disks in laminated timber for load distribution to shear walls
• Horizontal bracing stairwell core of reinforced concrete
