OWNERSHIP 

Promoter: AL2Bolig
Allotment rule: Danish Social Housing regulations
Reduction cost percentage compared to the market value:
– assignement % not sure
– rent % Depends on subsidization

ECONOMIC SUSTAINABILITY

Cost of construction max: The project cost of 11.000 DKK/m2 is very low compared to average building costs, especially for a demonstration project where a new structural system is tested and with the long term economic and environmental benefits in mind.
Rental/sale cost compared to market price: The costs of the project is regulated by national standards for non-profit housing (Danish Social Housing).

SOCIAL SUSTAINABILITY

Rules of allocation: Waiting lists. And special allocations as regulated by national standards for non-profit housing (Danish Social Housing)
Protection of fragile categories: With 27 different housing types and unit sizes ranging between 50-115m2 the project is intented for everybody.
Involvement of inhabitants in the building process: Yes, greatly. Resident representatives of the housing organization were the actual building client and many meetings were helt.
Community accompaniment in the life of the building: Lisbjerg Bakke has extensive resident democracy about most aspects of the building – economy, maintenance, social activities, rules of conduct etc

ENVIRONMENTAL SUSTAINABILITY

Functional mixitè: There is a communal room for social gathering and private events and communal laundry facilities, and storage.
Common spaces and shared living: The architecture is designed to promote social life – it is designed with wide access galleries, threshold spaces between private and public. Most cars parked outside the cluster to promote informal gathering between the buildings
Techniques and strategies for environmental saving: The project has DGNB Gold. Built in wood in a flexible system and designed for disassembly. Structural system is flexible for alterations over time. All façade walls can be exchanged. Untreated wood needs no treatment. Built using high levels of prefabrication

Description of the project: 

Lisbjerg Bakke / The future of wood construction is hybrid
‘Sustainable Non-profit Housing of the Future’ was the ambitious headline of the open competition for a series of demonstration housing schemes launched in 2014 by the Ministry of Cities, Housing and Rural Areas, the city of Aarhus, and the non-profit housing administrator AL2bolig.

Designed with a new hybrid wood-based construction system, the 40 units finished in 2018 is Vandkunsten’s idea of contemporary Danish wood architecture.

The 2-4 storey housing scheme is located in the hilly suburb Lisbjerg just 10 km from Aarhus. It has been designed as a small village with two dense housing clusters, each with a little ‘square’, and connected with a narrow street.

Hybrid system uses materials at their best
Vandkunsten Architects and the engineers at MOE have designed the wood-based beam and post system called Wood Stock. Laminated wood is used for posts, beams, the longspanning decks, and for the roof, and façade elements. Concrete and steel is used as well where it makes structural and practical sense. Concrete is excellent to fulfill strict demands for sound proofing in multi-storey housing. Hence concrete has been used in the access stairwells, elevator shafts, and as part of the decks. Steel beams replace wood certain places where additional support is necessary, and to keep the proportions of the building system. In this way the future of wood construction is in fact hybrid. Especially the beam and post system and long-spanning deck elements offer an immense flexibility freedom for floor plans as well as redesign to adapt for changing living needs in the future. The solid wood elements can all be disassembled and reused.

Wood defines the architecture
The architecture of Lisbjerg Bakke is defined by the use of materials and of the benefits of prefabrication.
Large, slender roof overhangs and over dimensioned drip edges across the facades adds structural protection of the untreated wood façade. Also, since the façade is not load-bearing which has offered full freedom to place window openings in the prefabricated wall elements.
