Appraisal adopted April 2011Read the Bloomsbury appraisal with its date in mind
Camden adopted the Bloomsbury Conservation Area Appraisal and Management Strategy in April 2011, replacing a 1998 statement, and Local Plan policy D2 says the council will take such appraisals into account. The area was first designated in 1968, has been extended many times and covers about 160 hectares, divided into sub areas such as Bedford Square and Gower Street, and Bloomsbury, Russell and Tavistock Squares. Several policies the document cites have since been superseded.

The strategy expects original joinery, sash windows, porches and front doors to be kept and repaired, and replaced only when beyond repair, and warns that insensitive re-pointing, painting or render harms historic brickwork. Fundamental roofline changes, intrusive dormers and poor materials will not be acceptable, with butterfly roofs, parapets, chimneystacks and expressed party walls of particular interest, and rear extensions are unacceptable where they would compromise the historic pattern of rear elevations.

Heritage index checked 4 October 2026No heritage Article 4 here, but two borough-wide directions
Camden’s index of heritage Article 4 directions, checked on 4 October 2026, contains none for the Bloomsbury conservation area. The appraisal gives the reason: with a high proportion of listed buildings and a limited number of properties holding permitted development rights, a direction was not considered appropriate. Its absence does not make an alteration acceptable; listing, the conservation-area guidance and the ordinary limits on householder rights still govern the work.

Two borough-wide controls do apply. Under the basement direction, adopted on 1 June 2017 according to Camden’s index, any basement excavation needs planning permission. Camden’s Class MA directions took effect on 29 July 2022 and, as modified by the Secretary of State, have from 23 February 2023 withdrawn the right to turn commercial premises into homes in the modified areas, mapped for the Central Activities Zone and Knowledge Quarter. They concern change of use, not work to an existing home; check the map for the building.

Plan of 3 July 2017; OSDC from 10 August 2026Know which plan applies and who decides
Planning decisions in Camden still rest on the Local Plan adopted on 3 July 2017. Hearings on a replacement plan, submitted on 3 October 2025, took place in May and June 2026, and in letter ED102 of 12 August 2026 the Inspector judged it unsound as submitted yet likely capable of being made sound through main modifications, which must go out to consultation for at least six weeks. With no consultation dates published as at 4 October 2026, treat the draft as emerging rather than adopted policy.

Camden Planning Guidance on home improvements, basements and design, each dated January 2021, is adopted but carries less weight than the Local Plan, and none of Camden’s adopted neighbourhood plans covers Bloomsbury. Since 10 August 2026, the Oxford Street Development Corporation has been the planning authority for part of the area near Tottenham Court Road station, so check its boundary map for the address before preparing an application.

Policy A5; Basements guidance January 2021Refitting a lower ground floor is not digging one
Bloomsbury townhouses generally have basements already, and refitting those rooms is a different brief from lowering a floor or extending underground. For a new or extended basement, Camden asks for a Basement Impact Assessment specific to the site, dealing with drainage, flooding, groundwater and structural stability. Local Plan policy A5 limits a basement to one storey, rules out building beneath an existing basement and restricts how far it may reach under the garden, and Camden Planning Guidance: Basements (January 2021) gives further guidance.

The appraisal adds that the council will resist infilling basement lightwells, and that where shops have infilled their basements and the pavement runs up to the building, excavating the basement would not normally be acceptable. A replacement basements policy, D6, sits in the draft plan under examination and is not adopted.

Find out which consents the exact Bloomsbury address needs before sashes are ordered, roof work is booked or excavation is promised. Each regime stands on its own: planning permission, listed building consent, conservation-area guidance, Article 4 controls, Building Regulations, landlord or estate consent under the lease and the Party Wall Act are decided separately, and clearing one leaves every other still to be settled.
