Open-Plan Conversions Clerkenwell

GS Renovation creates open-plan spaces across Clerkenwell, working in its post-war and new-build apartments and its loft-style warehouse conversions. We handle knock-throughs, kitchen-diners, broken-plan layouts and Crittall-style dividers, opening these homes up without compromising the structure that holds them together.

In Clerkenwell, a knock-through finished as one room typically costs £3,000 to £8,000 or more, including the steel beam (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Clerkenwell: the structural engineer we appoint designs the steel, we install it, and building control signs it off.

How the job runs

1. Free site survey at your Clerkenwell address, covering the walls, services and floor levels, and an itemised quote.
2. The engineer we appoint sizes the beam, and the work is registered with Islington Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. Props in, opening cut, beam on padstones; then floors, heating and electrics are joined up.
4. Building control inspects the steel before it is covered. We finish the room, and the completion certificate follows.

Open-plan living in Clerkenwell conversions

Clerkenwell's warehouse conversions already lean towards open volumes, so the work there is often about removing one remaining wall to link a kitchen and living area. In the post-war blocks and new-build flats that make up most of EC1, it is more often about reordering a compact layout around a fixed structure. Many of these dividers are non-structural partitions that come out easily; others are load-bearing and need a steel beam sized by an engineer, on padstones, with propping during a staged demolition.

Broken-plan is popular here because it keeps the loft feel while defining zones: a Crittall-style glazed screen between kitchen and lounge, or a half-height divider that preserves light across the whole floor. We design the layout around whatever is structural, so you get the open sightlines the space wants without hiding a beam where it looks awkward or losing the character of the conversion.

Housing in Clerkenwell

About 7,790 homes are listed for Clerkenwell, and the mix is 4% houses to 96% flats, with 65% built after 1945, 6% in 1919 to 1939 and 26% earlier. Since most homes here are flats, opening up a flat in Clerkenwell changes its fire escape route, which building control checks.

When a Clerkenwell open-plan scheme reaches the windows

Removing walls inside a Clerkenwell flat is a building control and lease matter, not a planning one. The planning question arrives when the new layout wants the outside to change as well, such as a window turned into a door onto a terrace or a new opening in the rear wall. Islington Council states that there are currently 42 conservation areas in the borough, among them the Clerkenwell Green conservation area (CA1), and it has removed permitted development rights in 40 of them with an article 4 direction to prevent some minor alterations.

In those areas you may need planning permission for changing external doors and windows. For a flat the position is firmer still, because flats have no householder permitted development rights, so a new or altered external opening in a Clerkenwell flat that changes its appearance is a planning matter wherever the building sits. We draw the internal and external work as one scheme but apply for them separately, so the knock-through can go ahead under building control while the change to the elevation is decided.

Consents for open-plan work in EC1

Since Clerkenwell flats are leasehold, an open-plan conversion that removes a structural wall needs the freeholder's licence to alter and the managing agent's approval of the engineer's scheme. Building-management rules on working hours, protection of shared parts and sound insulation between flats all shape how a knock-through is sequenced, and we settle those before starting so the job runs without hold-ups.

Any structural element, the beam and its bearings, is controlled under the Building Regulations and inspected by Islington Council's building control, not the planning department. Non-structural partitions and Crittall dividers carry no structural risk but still need doing neatly. Where the new beam bears into a wall shared with a neighbouring flat, the Party Wall Act applies and you serve the notice as building owner, using the drawings we supply.
