Halifax High School (Clare Hall)

The existing masonry school building, was converted into 50 luxury, one, two and three bedroom apartments. The existing large floor to ceiling heights allowed JNP to use part mezzanine floors to create additional floor space, without restricting natural light. The top floor school gym was divided into loft style apartments with exposed timber trusses and part mezzanine floors.

JNP Group  provided structural engineering and architectural services on the project.

Structural work involved, strengthening of the existing structure, including filler joist and timber floors, steelwork framing, timber roof trusses, walls and foundations.

Timber trusses in the top floor gym were strengthened to take the additional load from the mezzanine floors and repaired due to previous modifications carried out by the school.

A new passenger lift was installed and restrictions on space required the underpinning of the existing walls by piling.

These works enabled JNP Group to accurately define flood levels at the site, demonstrating that the majority of the site lay outside of the floodplain and guiding development layout and levels, ensuring no flood risk to the development.

Architectural services for the project included the preparation and submission of a Building Regulations application to the Local Authority and JNP Group also assisted and advised the developer/contractor throughout the works on issues relating to obtaining approval.

The conversion won the LABC award for ‘Major restoration and conversion’ for the Yorkshire area.
