Tate House is the former Tate Cars Headquarters in Leeds. The project entailed adding a two storey penthouse apartment extension on top of the existing building.

Avie worked with U-Roof Ltd, Beckwith Design and main contractor JM Construction to achieve a practical, speedy working solution to meet the program.

The proposed design for the project was a light gauge steel frame with a composite warm roof and rendered insulated panels externally. Because of the trapezoidal shape of the sub structure, a significant number of adjustable light gauge steel panels were necessary to avoid site installation issues.
The original structure required strengthening to the existing reinforced concrete columns and was fitted with a hot rolled transfer deck fixed to the original flat concrete roof.
There was an issue with overall height of the building hence the need to design a roof structure with minimal roof pitch and shallow diminishing purlins to achieve practical head room within the available space.

Restricted access was an issue and suitable storage and crane location areas were at a premium. Care was therefore taken to design floor cassettes and wall panels which could be installed without crane overload or reach issues.

Avie were able to provide valuable design input throughout the design and installation process including where unforeseen issues arose.
