The built heritage has come to us throughout history enduring wars, social and political unrest, the injury of time, and threats of demolition. It is our duty to protect it and pass it down to the future generations.

At Buro Happold we strongly believe that the best preservation is through reuse: a lived-in / worked-in / visited building is a building that is maintained and taken care of as it generates revenue.  The return is not only economical per se: the significance of a preserved landmark for a local community can sprout the regeneration of an entire area with increase property value and investment returns. That is why we have engaged in the conservation and refurbishment of historic and listed buildings for a long time, putting our multi disciplinary capabilities, our respectful and sensitive approach combined with our modern computational skills at the service of owners, design teams, local planning authorities.

Refurbishment and reuse of existing buildings also help fighting climate change by cutting the embodied carbon quota of the development thus reducing the carbon footprint of the building industry as a whole.

Warmington House

London, UK

Warmington House is a fine Grade II listed building and one of the best kept examples of Georgian architecture in London. Our facade conservation experts were appointed to provide advice for integrating the building into a new ‘Experience Centre’ as part of the Tottenham Hotspur Stadium Redevelopment, including a club museum and shop.

Through targeted structural investigation the condition of the timber structure, roof and masonry facade were assessed. Improvements to the overall thermal and acoustic performance of the facade were devised. This included sympathetic replacement of the front facade glazing with double glazed units fitted in the original frame rebates. Which was accepted by planning authorities due to evidence and explainable provided by our conservation specialists.

Additional advice was provided to deliver suitable reconstruction of the roof and abutment of the new, to the historic structure, without creating thermal bridges or condensation risk.
