Heritage Architecture is the continuation of a specialist practice originally founded in 1948, we carry out selective conservation projects to the highest standards.


We work in planning/urban design and in practical project construction exclusively within the historic cultural environment and on a wide range of historic buildings and conservation areas. Our surveys, appraisals and inspections are renowned for an intricate and holistic approach. We strive to promote quality with imagination and flair, where solutions for modern buildings in sensitive areas are always dictated by context.

The practice philosophy is based upon the SPAB principles of conservation and repair rather than replacement and renewal. The art of conservation is dependant upon knowledge and experience of historic methods of construction, decoration and furnishing and a discerning eye for detail. This historical accuracy is fundamental to all our heritage projects.



Stephen Levrant


How many architects know the difference between a metope and a guilloche? Precious few.

Stephen has spent his entire professional career in conservation and historic buildings, in both the public and private sectors of the profession. He worked for the precursor of English Heritage prior to joining the Frizzell Partnership, which he took over in the 90s. Known as a pragmatic and tenacious problem solver, he has dealt with many complex and sensitive issues in conservation from delicate and highly specialised repairs, through new build additions on sensitive sites, conservation area appraisals, legislation and planning matters, to major regeneration and development.

Unusual building types, imaginative re-use are of particular interest and many difficult problems have been solved through application of knowledge, experience and verve.  The lottery applications and conservation plans carried out by the practice are comprehensive and to exceptional standards. Stephen is a member of numerous conservation bodies, a past committee member of ASCHB and the Wallpaper History Society and served on two conservation area advisory committees.
