Advice on Unauthorised Works to Historic Buildings

We provide expert advice on unauthorised works to historic buildings, helping clients navigate complex planning and conservation issues where alterations have been carried out without the necessary consents. Such situations can carry significant legal and technical implications, particularly for listed buildings or those within conservation areas. Our approach is to assess the extent and impact of the works, identifying where they may conflict with heritage protections and advising on the most appropriate path to regularisation or remediation.

Our guidance typically includes liaising with local planning authorities, preparing retrospective applications where feasible, and recommending remedial works that bring a building back into compliance while minimising further disruption. By combining a strong understanding of planning legislation with practical conservation expertise, we support clients in resolving unauthorised works in a way that respects both the building’s historic significance and regulatory requirements. This ensures that any necessary corrections are handled sensitively, reducing risk and helping to safeguard the long-term future of the property.

FAQ

Our Specialist Historic Building Consultancy provides expert advice on assessing unauthorised works and identifying the most appropriate route to regularisation or remediation.

What should I do if unauthorised works have been carried out to a listed building?

If works have been undertaken without the necessary consent, it is important to seek professional advice before carrying out further alterations. We can assess the work, consider its impact on the building’s historic significance and advise on retrospective applications, remedial works and liaison with the local planning authority.
