Cullinan Studio: a new name AND a new office

  • Comment

Edward Cullinan Architects rebrands as Cullinan Studio with new BREEAM Excellent offices

Cullinan Studio is not just a renovated name for the practice. Founded as a cooperative under the banner of Edward Cullinan Architects in 1965, the name change is a symbol of a new era. However, the studio stresses that Ted is still heavily involved in the running and work of the practice. The practice’s new name also reflects the changing role of architectural services. Cullinan Studio said: ‘Ted’s philosophy and design approach has infused the practice’s work, methodology and cooperative structure - the name ‘Cullinan’ has come to represent a way of doing things - a culture. ‘Cullinan Studio’ reflects this.’

With the new name also come new offices, located next door to their former Baldwin Terrace studios in Islington, north London. The building, originally a foundry and later a greetings card warehouse, incorporates environmental features and has BREEAM Excellent certification. Following the completion of the foundry building, the construction of 12 residential units will begin on the site of the practice’s former office.

Footprint was invited to Cullinan Studios’ launch party and took the opportunity to have a look around their new studios. The building features highly insulated walls, natural ventilation and on-site renewable technologies.

Cullinan Studio architect Kristina Roszynski explained that although new foundations had to be made to support the south wall, the fabric was retained, reusing almost 80 per cent of the existing building.

A steel frame has been inserted into the existing Victorian masonry building to support the listed south wall and to provide a double height mezzanine within the office space.

Since the building is located in a conservation area, the practice decided to insulate internally incorporating a 300mm layer of recycled newspaper onto the inner face of the south wall. Double glazing was installed on the north elevation only.

The studio is naturally ventilated; a stack effect is produced as hot air accumulated in the south area of the building is released upwards through the central atrium. Cross ventilation is provided in the ground floor where the hot air is released through small openings in the north wall.

Kristina emphasised that the project is a demonstration of team work since it symbolises ‘collaboration and working together’.
