Planning and building regulation drawings in Bloomsbury (WC1E)

Bloomsbury is a formal Georgian townscape. Terraces of brown and yellow stock brick frame the garden squares, and Bedford Square, Montague Street, Store Street and Great Russell Street are among its streets. Many of the buildings are in university, institutional or office use, with homes on the upper floors, and a high proportion are statutorily listed as well as lying within a conservation area. For a homeowner, that combination shapes nearly every decision: the first question is what may be altered at all, before how much can be added.

Projects here therefore tend to be careful. Work to the rear and the roof is controlled because the setting of the square and the visible skyline are protected, and anything visible from the square is scrutinised closely. Work here can include refurbishing an upper-floor flat, reconfiguring an interior, repairing or replacing windows, or converting a floor between office and residential use. Where a building is listed, listed building consent is needed alongside any planning permission for works affecting its character, and it can reach internal works as well as external ones. Like-for-like repair is not development, which helps with maintenance, but the difference between repair and alteration should be settled before work starts.

Change of use is a sensitive subject where university, museum and institutional uses are so concentrated. The Bloomsbury conservation area is the main designation, and Fitzroy Square and Charlotte Street are also Camden conservation areas to the west. Flats have no householder permitted development rights, and the practical limit on what a leaseholder can do often comes from the lease and the freeholder, even though a planning application itself needs only the correct ownership certificate or notice. Camden also asks for a Basement Impact Assessment for below-ground works. We check the listing and the designations first.

Planning in Bloomsbury: what to know before you apply

Conservation designations reach across most of Camden and listed buildings are numerous, so a homeowner here should not assume permitted development applies. Bloomsbury adds the formal garden-square setting, which tightens control of rear and roof additions and of anything visible from the square. Camden also operates a demanding basement policy: a scheme that creates or extends a basement or lower-ground floor generally needs a Basement Impact Assessment covering structural stability, drainage and groundwater. Listed building consent is a separate permission from planning. Residential conversion of institutional or office floors is treated as a sensitive change of use. We confirm the exact constraints on your address before drawing.

Applications are decided by London Borough of Camden — its planning pages.

A single-storey rear extension up to 4 m deep on a detached house, or 3 m on any other house, is Class A permitted development subject to the height and materials conditions.
An Article 4 direction applies here and may withdraw this freedom — the schedule must be checked before relying on it.

Where permitted development applies, a lawful development certificate proves it for lenders and buyers.

FAQ

Bloomsbury (WC1E) — FAQs

Do I need consent to change a window in a Bloomsbury flat?+

Possibly more than one. A flat has no householder permitted development rights, and if the building is listed, listed building consent is needed for works that affect its character. A like-for-like repair is not development, but a change of design or material may be.

Can I dig out a basement under a Bloomsbury house?+

It is possible in principle, but Camden's basement policy sets a demanding test. A Basement Impact Assessment is generally required, and the listing, the conservation area and the neighbouring structures all need to be examined first.
