Extending a Georgian house in Bath
Listed buildings ask more of an architect. Here is what to expect, and why it is worth it.
Bath is a World Heritage city. Most of its Georgian houses are listed, and many sit within a conservation area. That does not mean you cannot extend. It means you must extend well.
Start with significance
Before drawing anything, we prepare a heritage assessment. It records what is special about the house and what is not. Later additions, poor repairs and lost features all matter. The assessment shapes the design and supports the application.
Subordinate, not invisible
Conservation officers in Bath and North East Somerset generally favour additions that are clearly modern but deferential. Lower than the main house. Lighter in material. Honest about their age.
Timescales
Allow eight to thirteen weeks for listed building consent after validation. Pre-application advice adds time at the start but often saves months later.
If you are considering an extension to a period home in Bath, we are glad to visit and talk it through.
