Our Services

We undertake historic appraisals, condition assessments and the preparation of schedules of significance, morphological plans and repair schedules, which provide detailed maintenance regimes and a serve to inform potential change. We believe that the fabric of a building must be understood, both as a whole and as a collection of constituent parts to be treated and preserved individually. We are always interested in formulating new methods and approaches for preserving original materials which may have hitherto never been consciously conserved.

Our built heritage consultancy services deal with the conservation of listed buildings; complex legal and planning matters; urban design and regeneration in conservation areas; and the appraisal of tall buildings having impacts on city form and townscape. The assessment of impact likely to result from particular developments as well as the appraisal of alternative developments form a major part of our workload, and as a result, we thrive on challenging problems.

Listed building Enforcement Notices are served under the PLANNING (LISTED BUILDINGS AND CONSERVATION AREAS) Act 1990.

Unlike other parts of the Planning Acts it is a criminal offence to carry out any works to a listed without consent. Unauthorised works to a listed building which effect its character as a building of special architectural or historic interest is an offence under Section 9 of the Planning (Listed Buildings & Conservation Areas) Act 1990.

Such an offence is liable for a fine up to £20,000 and/or up to 6 months’ imprisonment if found guilty in the Magistrates’ Court, and an unlimited fine and/or up to 2 years’ imprisonment if convicted by the Crown Court.
Demolition of an unlisted building in a conservation area without planning permission is also a criminal offence, the penalties are the same as for listed buildings.

An Enforcement Notice can be served to rectify any works done without planning permission or work done in breach of a condition on such a consent. Breach or failure to comply with the enforcement notice is also an offence.

Liability “runs with the land” and there is no limitation of time; so that even if a previous owner carried out unauthorised works, the present owner can be served an Enforcement Notice to rectify, but only the perpetrator can be prosecuted. Prosecutions can be brought against all those responsible and usually include: the owner, the architect and the contractor. Ignorance of the law is no excuse, and even if the fines may be relatively low, those convicted will have a criminal record.

Heritage Architecture Ltd specialise in complex listed building enforcement issues, unauthorised works, listed building enforcement notices, retrospective consent applications and appeals. We also offer pre-purchase inspections to advise if any unauthorised works have been carried out as this is never apparent from usual legal searches.
