Listed buildings
Working with, not against, the character of a protected building
Why Listed Work Is Different
Every detail matters
The UK has over 400,000 listed buildings. Each one is a conversation with history, and every alteration, however small, requires Listed Building Consent before work can begin.
Listed buildings are a particular interest of the studio: the meeting of old fabric and new design. This guide explains the consent process in plain English.
The Consent Process
Listed Building Consent, step by step
Listed Building Consent runs in parallel with planning permission. Both are needed for most external work; LBC alone for internal alterations.
Every application needs a written statement assessing the building's significance and explaining how proposals respect it. We write this in-house.
Discuss proposals with the conservation officer before submission. Identifies concerns early and shapes the design. We always recommend this for listed work.
Drawings, heritage statement, photographs, justification. Submitted alongside planning if both are needed. No fee for LBC itself; planning fees apply separately.
Historic England consulted on Grade I and II* applications. Local conservation societies and Historic Buildings Officer give views. 21-day public period.
Typically 8–13 weeks. Approved, approved with conditions, or refused. Conditions usually relate to materials, sample panels, and supervision during work.
Many consents condition that work is supervised by the architect or a heritage specialist. We attend site fortnightly throughout to ensure consent terms are met.
Design Principles
Five principles that guide every listed project
Listed Building Consent isn't a hurdle to clear: it's a framework for good design. These five principles shape everything we do on heritage work.
Wherever possible, new interventions should be reversible: capable of being removed in 50 years without damaging what was there. This usually means contemporary additions in contemporary materials, distinct from the original.
New work should read as new. Pastiche, pretending new additions are old, is generally discouraged. Honest contemporary work that respects the original is preferred.
Don't change what doesn't need changing. Existing fabric is presumed to be of value until proven otherwise. Every removal must be justified.
Where original materials are used (lime mortars, traditional renders, hand-made tiles, sash windows) they should be specified by an expert, sourced from a known supplier, and laid by a specialist.
Before drawing, understand. What is this building's significance? When was it built? What's been altered before? Why? Good design comes from this understanding, not from imposing a style.
A good relationship with the conservation officer is invaluable. We engage early, listen carefully, and treat their input as collaboration not obstacle.
Common Mistakes
Five things to avoid
Most listed building refusals come back to one of these five errors. All are avoidable with the right process.
Unauthorised work on a listed building is a criminal offence carrying unlimited fines. Even removing a cornice or replacing a window without LBC is illegal. Always consent first, work later.
Extensions designed to "match" the original in a fake-historical style usually fail. Better: a clearly contemporary addition that respects the original's scale and materials.
Cement mortar on a lime-built wall causes accelerated decay. UPVC windows in a sash-window opening spoil the elevation. Specifying the wrong material is one of the fastest refusals.
Submitting a heritage statement that just lists what's there, rather than analysing significance and explaining the design rationale, gets refused. A good statement is the application's strongest document.
A general builder who's never worked on a listed building will damage what they touch. Specialist contractors cost 20-30% more, and save many times that in not destroying the asset.
Refusing pre-app advice "because we know what we want" usually backfires. The conservation officer is the consent's gatekeeper: work with them, not around them.
Our Approach
Three stages of listed work
How we structure a listed building commission, from first conversation to handover.
Site visit, measured survey, archive research, conversations with conservation officer. Before drawing, we build a deep understanding of what we're working with.
Pre-application meetings, heritage statement, design refinement. The consent stage: much of which happens before formal submission.
Tender to known specialist contractors, regular site inspection, conservation officer site visits, sign-off. Quality control through completion.
