CIRCLE HOUSE

 

 

The stated objective is for 90% of the project’s

housing materials to be reusable

without loss of value.

CIRCLE HOUSE WILL MAKE THE WAY FOR CIRCULAR BUILDING

The Circle House project aims to develop and disseminate knowledge about circular construction across the industry and across silos. That’s why the project brings together 30 different companies across the entire value chain of the building. The goal is a scalable circular lighthouse building that is offered and marketed.

BACKGROUND

The Circle House project consists of 60 social housing units in Lisbjerg outside Aarhus, which is expected to be completed by 2020. In addition to serving as housing, Circle House is a scalable demonstration project that can give the construction industry new knowledge about the experience of circular building.

The project is supported by the Danish Environmental Protection Agency’s Environmental Technology Development and Demonstration Program (MUDP) and Realdania’s Innovation Program in Construction.

The building is sketched by the a Collaboration Studio between 3XN Architects, Lendager Group and Vandkunsten. The project is expected to be offered in 2018, construction start in 2019 and completed in 2020.

TYPOLOGIES

2 FLOOR TARRACE HOUSE

The terraced housing units with 2 floors are laid out with an entrance, bathroom, dining area, kitchen and living room on the ground floor. The 1st floor has one large and one small bedroom and a small living room/study. The interiors can also be laid out differently, e.g. as two small bedrooms and one large living room or two large bedrooms.

1-FLOOR TARRACED HOUSE

The one-floor terraced units have a similar layout for the entrance, bathroom, dining area, kitchen and living room. For the bedrooms, there is the freedom of making one large and one small room, two medium-sized rooms or four small ones.

THE TOWER BLOCK

The tower blocks will incorporate all the alternative style flats and common facilities. All units will have access to a shared staircase.

CIRCLE HOUSE DEMONSTRATOR

The Circle House Demonstrator is a 1:1 mock up and exhibition space, where all the building’s layers, materials and products are exposed, displayed and described.

SUPERSTRUCTURE

The superstructure was erected very quickly onsite and the contractor was very pleased with the process. It took the one hour in total to erect the walls before they would have been ready to mount the next floor.

LAYERING SYSTEM

Circle House consists of several building systems that will be reusable for other buildings and thus retain their value. The concrete element of the demonstrator will be demounted and reused in the final Circle House project. In that way the circle will be closed already in this project.

STEEL FACADE HANGERS

The circular superstructure is based on already existing solutions from the Circle House partners: Precast concrete elements from Spæncom, mechanical joints from Peikko and connections is cast with lime mortar from Kalk.

SHINGLES FROM UPCYCLED PLASTIC WASTE

Because the system is what counts, there is an architectural freedom in the choice of materials when it comes to circularity in the building concept. 

TILE AND WOOD SHINGLES

In the design proposals, the formats are either kept as large (full sheets) or as small (shingles or boards) as possible in order to maximise their potential reusability value.

EXPANDED CORK BOARDS

The facade material is fitted using screws or mountings in order to preserve its value for subsequent reuse.

OPENING DAY

The demonstrator is placed by the client Lejerbo’s headquarter in Valby, Copenhagen. Here it is being used as a meeting and event space to inspire collaborators, business partners and curious passers by.

INTERIOR DESIGN

The interior of the demonstrator is a curated of exhibition of circular materials, products and solutions. Everything features descriptions, contact informations and links to websites so it’s easy to go from inspiration to implementation.

SAMPLES OF CIRCLE MATERIALS

Demonstrator shows a catalogue of available circular solutions for the industry and promotes the companies circular products to a larger audience.
