INSIGHTS SITE LINES A heritage refurb checklist
Simon Castle from Chisholm & Winch discusses the varied, but essential considerations that architects need to bear in mind when approaching listed building renovations
A
ccording to Historic England, there are estimated to be around 500,000 listed buildings on the National Heritage List for England (NHLE). A listing marks and celebrates a
building’s special architectural and historic interest, and protects it for future generations. The older a building is, and the fewer the surviving examples of its kind, the more likely it is to be listed. Heritage restoration is the process of accurately recreating the character, features, and structure of a building, as it would have been at a particular time.
This is one of the first and most important aspects to consider during heritage renovation, as these buildings are so precious to our built environment, partly as they act as a window to our history. Heritage restoration is also an economical and environmentally responsible practice. It’s a delicate process that requires careful planning and execution to preserve the historical significance and aesthetic value of a building while simultaneously making it fit for modern purposes.
The challenge is that most older properties were not constructed for 21st century tastes, or performance. If they are to be practical, sustainable, attractive buildings for the modern era, there is a delicate balance to be struck between preservation and innovation. We must maintain the character and integrity of the existing structure, while updating it for a new generation of use.
Historical significance
Before beginning any refurbishment work, it is important to understand the historical context of the building, as well as any regulations or guidelines that may apply to the renovation. In some cases, certain aspects of the building may need to be preserved or restored to maintain the integrity of the structure which can involve using traditional building techniques and materials or replicating certain features to match the original design. Chisholm & Winch worked on a project for The Crown Estate to upgrade a five-storey Regency house in west London, located between Mayfair and St James’s, and provide luxurious private rental accommodation.
Some of the rooms within the building have original Georgian timber panelling; our remit included refurbishing these, as well as matching new timber panelling to the original where replacement was required, and restoring those areas that could be preserved. One of the showpiece elements of the project was a new staircase that curls through the centre of the property. Here, new balustrades and bannisters, in keeping with the period, were installed to create a feature that is not a pastiche of the original, but immediately references the period.

Oak floors throughout the building marry traditional materials with contemporary tastes, and bespoke joinery across the luxury kitchen, custom-fitted wardrobes, spacious wine cellar and heritage doors echoes the workmanship of the original building while updating it with contemporary style.
Meticulous planning
Developing a comprehensive plan that includes realistic timelines, budgets and a detailed outline of the renovation helps to reduce risk and potential downtime throughout the project. Some construction companies have their own experienced project managers that plan every project down to the very last detail – so they know exactly what is being projected and what can be delivered. Timings and budgets need to be communicated to all stakeholders so that everyone is aware of any upcoming variations.
Materials & techniques
The materials and techniques used in a heritage renovation project are essential to preserving the historical significance and aesthetic value of the building. In some cases, it may be necessary to source specialised materials or employ traditional building techniques that are no longer commonly used. Older buildings are often made with unique
