Planning permission in Richmond borough is, by almost any measure, more complicated than anywhere else in London.
This is not opinion, it is the professional consensus of architects and planning consultants who work across the capital. The London Borough of Richmond upon Thames has 85 conservation areas, thousands of Buildings of Townscape Merit, a borough-wide Article 4 direction for basements and 14 separate Village Plans that sit on top of its Local Plan and the national planning policy framework.
If you own a property in Twickenham, Richmond, Kew, Barnes, Ham or anywhere across the borough, understanding how this layered system works is essential.
Why Planning Permission in Richmond Borough Is Different
Most London homeowners approach planning with a reasonable working knowledge of the rules: permitted development rights allow certain extensions without formal permission, a householder application covers larger works and conservation area consent adds an extra layer where relevant.
In Richmond, that model breaks down almost immediately.
The borough has more conservation areas than virtually any other London authority. Each one comes with its own character appraisal, its own restrictions and its own interpretation of what constitutes acceptable development. There is no single rule for what is or is not permitted within a Richmond conservation area. The policy is applied area by area and building by building based on the character and architectural vernacular of each specific location.
This means that a rear extension that passed planning in the Castelnau Conservation Area last year tells you very little about whether a similar proposal will pass in Strawberry Hill or Ham. That’s why local knowledge is the difference between a successful application and an avoidable refusal.
The Village Plans Layer
This is where Richmond’s planning environment becomes genuinely unusual and where most homeowners and many architects get caught out.
The borough is divided into 14 village areas, each of which has its own Village Plan. These Village Plans apply on top of Richmond’s Local Plan, which itself applies on top of national policy. The result is a three-tier system in which a proposal can comply with national permitted development rules, satisfy the borough’s Local Plan policies and still fall foul of a village-level plan that has not yet been published online.
Planning officers in Richmond are known to work to policies that are in development but not yet publicly available. The practical consequence of this is that applications which appear to satisfy all published criteria can be refused on grounds that applicants could not have known about without direct pre-application engagement with the council.
This is a documented pattern that experienced Richmond architects navigate by maintaining direct contact with planning officers before submitting formal applications.
Buildings of Townscape Merit
Alongside its listed buildings and conservation areas, Richmond has thousands of properties designated as Buildings of Townscape Merit, sometimes called locally listed buildings or non-designated heritage assets. These are buildings considered important to local heritage but not formally listed under national legislation.
In theory, Buildings of Townscape Merit carry fewer formal restrictions than listed buildings. In practice, Richmond’s planning officers treat them with comparable seriousness. Applications involving material changes to these properties are scrutinised carefully and the design quality of any proposed works is expected to demonstrate a genuine understanding of the building’s character and local context.
If your property is a Building of Townscape Merit, your architect needs to know it and needs to address it explicitly in the application.
When Do You Actually Need Planning Permission?
Not every project in Richmond requires a formal planning application. The starting point is always whether the proposed works fall within permitted development rights.
For houses, not flats or maisonettes, permitted development allows certain extensions, loft conversions and other works without formal permission, subject to specific conditions around size, materials and proximity to boundaries. However, in Richmond, several factors can remove or restrict those rights:
Conservation area location
Certain works that would be permitted development elsewhere require a planning application within a conservation area. This applies particularly to changes visible from the street, such as front extensions, roof alterations and some external cladding.
Article 4 directions
Richmond has Article 4 directions in place across significant parts of the borough. These are formal directions that remove specified permitted development rights, requiring a planning application where one would not otherwise be needed. The borough has a specific Article 4 direction for basement works across the entire borough, meaning any basement conversion or excavation requires full planning permission regardless of where in Richmond you are located.
Flat and maisonette exemption
Permitted development rights apply to houses, not flats or maisonettes. Given that a substantial proportion of London’s housing stock sits in converted properties, this catches a large number of Richmond homeowners by surprise.
The Pre-Application Process
For any project in Richmond that involves design-sensitive elements – conservation area works, Buildings of Townscape Merit, heritage assets or complex site constraints – pre-application advice from the council is strongly recommended and, in many cases, should be treated as essential rather than optional.
Richmond offers a paid pre-application advice service. The cost varies depending on the scale and nature of the proposed works. What it provides is an early-stage steer from planning officers on whether a proposal is likely to be supported, what design issues they foresee and what additional information or modifications might strengthen the application.
The investment is invariably worthwhile. A refused planning application wastes months of time, costs money in professional fees and, in Richmond’s planning environment, can set a precedent that complicates future applications on the same property.
Working With an Architect Who Knows Richmond
Planning permission in Richmond borough is not something to approach with a generic set of drawings and a hope that it meets the criteria. The borough’s planning environment rewards preparation, local knowledge and a design approach that engages directly with the character of the area.
