The Moholt 50|50 project in Trondheim, Norway, aims to improve student housing by introducing new collective-oriented units, support services, and public programs. It creates an active central area that connects the student village with the surrounding area. The project includes tower constructions where each floor is a student collective with shared spaces. Additionally, it features a kindergarten, library, and public spaces. All buildings are constructed using cross-laminated timber (CLT) and have an ambitious energy concept, including geothermal heating. The use of CLT reduces CO2 emissions and the project is the largest CLT project in Europe. The towers have a 9-storey height, with CLT elements used from the first to the 9th floor. The project utilizes the aesthetic qualities of CLT and conducted fire tests. The façade cladding system accommodates shrinkage and is clad with Kebony treated pine wood panels.

Student housing often plumb the depths of mediocrity, with simple units stacked on top of each other in the cheapest way possible and left to themselves without support programs. The Moholt 50|50 project is a reaction to this. By injecting new collective oriented housing units, support services for students and public programs into an existing student village built in the sixties, a new active central area is created, erasing the psychological border between the student village and the surrounding area.

The project is located in Trondheim, Norway. The title Moholt 50|50 represents a turning point in the history of the student village. 50 years after the inauguration of the first student units at Moholt student village a competition for young architects was arranged looking for a vision for the coming 50 years. True to the ideals of the student organization – offering both private space for individual needs and collective space promoting collaboration, social responsibility and tolerance, the winning project proposed tower constructions where every floor is a student collective. Every collective consists of 15 units with individual bathrooms. The habitants of the units share a kitchen, dining/ living room, entrance hall and a guest toilet. The ground floors of all towers offer spaces for more publicly oriented services of the student organization and commercial spaces. In addition to the student housing towers the masterplan consists of a kindergarten and a library with spaces for student activities. All buildings are constructed in crosslaminated timber (CLT) and have an ambitious energy concept. Moholt 50|50 is the largest CLT project in Europe. The guiding idea was to lay out a “street” through the student village, a coherent and active public space. Moholt allmenningen (Moholt commons), as it is now officially called, brings together existing small paths and roads to a larger public space and connects them to the larger road system. All new buildings are connected to this street which brings together movement and activity connected to the buildings. The Moholt Commons is a “shared space” area, also available to emergency vehicles, deliveries and handicap vehicles. It is designed as a public space with benches, stages, bicycle parking and planting – a place where people can meet. In the original competition proposal the towers were planned with conventional construction methods; a steel and concrete structure with a brick cladding, the latter in order to harmonize with the existing low-rise student housing with redbrick facades. To meet the project’s energy and climate goals the project team researched the possibility of turning the structures into CLT constructions. The towers, with their relatively short spans and Y-shape volumes, were statically optimal for CLT-construction. The choice of CLT in load-bearing structures, the reduced energy need in accordance with the “passive house standard” and geothermal heating are the main elements of the environmental concept for the project. The local heating plant consists of 23 geothermal wells, heat recovery from ventilation air, heat recovery from waste-water, and solar thermal collectors, all of which provide for an integrated energy system.

The use of CLT has reduced the CO2 in building materials by 57 % and the CO2 emissions associated with energy use are reduced by approximately 70% compared to standard Norwegian requirements. db77d1a7fbc36aa2769d9d623707981f2eb6d65f e7059104b8f3c628405c8bc8408ffaf6f0b22661

The five towers are 9-storeys high with a height of 28-metres. The basement and ground floor levels are made in cast reinforced concrete. From the first floor to the 9th floor the structure consists of prefabricated CLT-elements.

The approach to building with CLT was to take advantage of the finished surface of the CLT elements and expose as much as possible of the wood in the interiors. By utilizing the technical and aesthetic qualities of the CLT system a robust and honest expression was achieved.

A full scale fire test was conducted to establish a better information basis for fire sizing, burn rate and sprinkler capacity.

Like regular wood structures, CLT wood structures have the characteristics of shrinkage in tangential and radial direction. The façade cladding system of the student towers is designed to give it a telescopic characteristic, which can absorb the shrinkage of the floor elements without creating tensions in the cladding.

The façades are clad with Kebony treated pine wood panels. The cladding on the ground floor is treated with a fire protecting wood stain, whereas the rest of the Kebony façade is left untreated and will weather naturally.

In Trondheim, Norway, the project aims to provide ample light and views for residents in the Svartlamoen neighborhood. Originally an industrial zone, it was rezoned for residential use as part of an ecological urban development initiative. A competition was held for an innovative wood-based residential building, resulting in a sustainable design with shared facilities, compact solutions, and flexible spaces. The project comprises two buildings: a five-story block with commercial space on the ground floor and shared flats above, and a smaller volume with single-room flats. The structures feature untreated timber components, providing column-free spaces.

How to give the greatest amount of light and the best view to the largest number of residents. Located in Trondheim, Norway’s third largest city, the site for the project is a rather run-down area called Svartlamoen that was established in the 18th century as an outlying working-class neighbourhood. Although it was rezoned for industrial use in 1947, all plans for such development were scrapped in 2001 when it was rezoned once again, this time for residential use. All city-owned property in Svartlamoen was transferred to a new foundation. The aim is to develop the area as an example of ecological urban development, with low-cost housing.

During this period, an initiative by the residents led to an open competition for a new residential building that would full this objective. Moreover, the competition called for innovative solutions for the use of wood in an urban context.

Consequently, the design strategy was based on shared facilities; compact solutions; simple detailing as well as a high level of flexibility with respect to possible future changes in the programme resulting in a sustainable project with an economical total build price.
The project consists of two buildings with a total of 1030 m². The largest volume is a five-storey block with commercial space on the ground floor and shared flats for five to six people on the other four floors. While the bedrooms are compact and oriented toward the north, the communal spaces face the backyard on the south side which is characterised by large windows and an external staircase. On the top floor, the bedrooms are even more compact, thereby increasing the size of the communal space. The smaller volume contains small single-room flats.

All the structural members are untreated massive timber pieces that are factory produced and assembled on site. Only the exterior wall elements are load bearing, providing a column-free space on each storey.
