Plans have been submitted for major maintenance works to improve the thermal performance of two high-rise buildings on Wearside.

Housing association Gentoo Group has applied for planning permission for works to the Church Street North and Dock Street tower blocks in Roker.

An accompanying design and access statement confirms the project aims to “replace the windows to resolve thermal performance issues”.

Current windows at the tower blocks are double glazed, were refurbished in 1996 and were not scheduled for “lifecycle repairs” until 2036.

Plans have been submitted to replace windows at Gentoo's Church Street North and Dock Street tower blocks in Roker.

However, there have been increasing complaints and repair issues with the windows, suggesting they have deteriorated faster than expected.

Gentoo bosses said the improvement work at the tower blocks was part of the firm’s “ongoing commitment to providing warm, safe and decent homes for our customers”.

This includes the “replacement of windows and external panels, roof improvements and external decoration and render repairs, helping to improve the energy efficiency and overall performance of the buildings”.

Sam Granger, assistant director of asset strategy and data at Gentoo, said: “These improvements would help make homes warmer, more comfortable and more affordable to heat, while also extending the lifespan of the buildings.

“Residents have been informed of the proposals. Subject to planning approval, the outcome of the tender process and approval from the Building Safety Regulator, we will continue to assess the viability of the project and determine next steps.

“All work we carry out on our high-rise buildings must meet strict building safety requirements.

“This includes detailed design checks, safety reviews and formal approvals at several stages, and we will keep customers informed throughout the process.”

She added: “We know that customers want homes that are comfortable, energy efficient and fit for the future.

“If approved and progressed, this project would support our ambition to improve the energy performance of our homes while ensuring our high-rise buildings remain safe and desirable places to live.”

A decision on the plan is expected following a consultation.
