Listed Building Extensions and Alterations

Extensions and alterations can maximise space, enhance a property’s appearance, and provide other practical improvements. There are regulations in place for extending or altering older properties, such as listed buildings. Before any work begins you’ll need to have good quality plans in place and the correct paperwork.

At Validus Construction we’re experts in heritage building work. We can draw up or assess your existing building extension and alteration plans and advise on appropriate steps. Our team of specialists can then undertake any extension and alteration building work with great levels of care to preserve the historical value of such buildings.

Our building extension and alteration services

We can help with every stage of building an extension or making alterations, from the planning phase to putting in the last brick.

When it comes to extending a listed building, we combine modern building methods and innovative equipment with traditional craftsmanship techniques. This helps retain the original design elements and character, ensuring all work is completed within the relevant regulations.

Within our building extension and alteration services we can construct, adapt, and convert many areas of your property, including: 


Consent for extensions and alterations

Adding an extension to a building of any type, age, and size often requires planning permission (and sometimes building regulations approval). You can sometimes make alterations without needing special permission, but it’s advisable to have an expert check your plans first. This avoids damaging the structural integrity of the property.

With older, historic, and listed buildings you must have listed building consent before making any alterations or adding extensions. This is required when any work could impact the character or appearance of a listed building (such as a building of special architectural or historic interest).

You can apply for listed building consent through your local planning authority before any work starts. We can help you through the process and offer a consultation on your plans to improve their chances of approval. Extensions and alterations to a listed building without consent is a criminal offence and individuals can face prosecution.
