The housing group has started the hunt for suitable demolition contractors to do the job, which is set to be one of the biggest demolition contracts let this year.

The housing charity said renovating the six blocks would not be cost-effective and would still only provide buildings with the same energy efficiency as when they were first built.

A firm decision has yet to be taken on whether to opt for explosive demolition or tear down.

Presently it is envisaged that just Tennyson House is suitable for explosive demolition, although contractors are open to submit explosive demolition proposals for another four blocks – Albion House, Nelson House, Garibaldi House and Thesiger House.

The sixth Bevan House is too close to an existing building, meaning it will be ripped down.

Stripping and weakening of the 15-storey structures will begin in the early New Year and will take around 12 months to complete.

Structural and civil engineering consultancy Alan Wood and Partners is the client’s agent and principal designer.

Prequalification questionnaires need to be returned by 13 September and can be found on the tender website.
