Building work in Bloomsbury: area guide

This is our area guide to building work in Bloomsbury (WC1, Camden): the housing, the council rules that apply (Camden Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Bloomsbury.

Two kinds of home dominate Bloomsbury and they behave nothing alike. Around the garden squares near the British Museum and Russell Square stand Georgian terraces with brick vaults under the pavement, lime mortar and floor joists spanning the full depth of the house. On VOA figures, most WC1 homes are flats, many in mansion blocks: purpose-built, held on long leases, with a communal stair and a managing agent. Know which set of rules applies before anything is drawn, because the first governs how the fabric is treated and the second governs what you may touch at all.

On the valuation list Bloomsbury counts about 14,890 homes, 97% flats and 3% houses; 49% predate 1919, 13% are interwar and 37% post-war.

How Georgian fabric wants to be treated before a wall comes out

A Georgian house was built to move moisture rather than resist it: solid walls in lime mortar, lime plaster inside, and timber that relies on drying out. Wrapping that in cement render or dense gypsum pushes damp somewhere else instead of solving it, and it is the most common cause of the problems we are called to in these houses. Repointing in lime, a breathable plaster and better ventilation usually achieve more for a WC1 lower ground floor than any injected treatment, and that comes before any finish.

Structurally the pattern is consistent. Deep joists run front to back onto the front and rear walls and a central spine, thin partitions divide the rooms, and the staircase often gives the plan its only real lateral stiffness. So taking out a wall is a structural alteration job judged in the round, not opening by opening, and the engineer we bring in looks at the whole floor plate before specifying anything. Where a house is listed, listed building consent covers internal alterations as well as external ones, and we build only what has been approved.

Mansion flats, leases and central London access put the licence before the layout

Permitted development rights do not apply to flats. Every external change needs planning permission, and internally the lease decides what is possible: almost all require the freeholder's written licence to alter before a wall moves, a bathroom relocates or floor coverings change. So a bathroom renovation that moves the room, or an open-plan conversion job, starts with that licence, which normally depends on drawings, the engineer's design, a method statement and the contractor's insurance, and the freeholder's own surveyor may review the lot. We assemble that pack, and work does not begin until consent is in hand. Planning and lease consent are separate tracks and can run at the same time.

Then there is central London itself. There is no rear access, generally nowhere to stand a skip, and loading is restricted along most of WC1. Blocks impose working hours, lift protection and rules about the common parts, while university and museum traffic decides when a vehicle can realistically reach the door. Materials arrive in timed, modest loads, waste leaves the same way, and the communal stair is sheeted before anything moves through it. All of that is agreed with the managing agent in advance, so the location limits the logistics, not what can be built.
