Office fit out in Clerkenwell EC1
Converted warehouse and light-industrial floors — generous, characterful, and almost always without the service infrastructure a modern fit-out assumes.
What you are fitting out in Clerkenwell
Former warehouses, workshops and printworks converted to offices and studios: deep floor plates, exposed structure, good ceiling heights, timber or concrete floors, and services retrofitted into buildings that had none. Alongside them, period terraces around the greens and a smaller amount of new build.
Design, architecture and creative practices, showrooms, and technology businesses that took the space for what it looks like. Briefs are usually open plan with a small number of closed rooms, and the recurring problem is acoustics — an exposed hard-surfaced warehouse floor is a reverberant room before anyone furnishes it.
The constraint that sets the programme
Mixed and worth establishing early. Some conversions have a retained goods lift or loading door from their industrial life; many have neither, and material goes up a single staircase. The streets are narrow, servicing is competitive, and bay suspensions are applied for in advance. Where the building is shared with residential conversions above, working hours tighten accordingly.
Who decides, and what needs consent
LB Islington is the authority, with 42 conservation areas and Article 4(2) Directions in force in conservation areas that can require permission for minor alterations. The ones that matter commercially are the Class E to C3 directions: Islington made three in November 2016 — one covering the Central Activities Zone within the borough, which takes in this district — confirmed them on 28 July 2017, added four more in August 2023 and six in July 2025. The effect is that an office floor here cannot be converted to residential under permitted development. Internal fit-out remains a matter for the licence to alter rather than for planning.
A fit-out normally answers to three separate things: your landlord’s licence to alter, building regulations where services or fire strategy change, and planning only where the outside of the building or its use changes. They run on different clocks and the licence is the one most often discovered late.
What we are usually asked for in Clerkenwell
- Cat B fit-out of a converted warehouse floor
- Acoustic strategy for a hard-surfaced open plan, specified rather than hoped for
- Bespoke joinery and reception made in our own workshop
- Seamless resin floors over existing industrial substrates
- Services retrofit coordinated with exposed structure
- Reinstatement at lease end on a converted building
Partitions, joinery and glazing come from our own companies rather than a chain of subcontractors, which is why the timing and the warranty stay in one place. The low-waste method — refinishing over what is already there — is what makes most of this workable in an occupied building.
Why is acoustics the first problem in a Clerkenwell warehouse conversion?
Because the qualities that make the space worth taking — exposed brick and concrete, high ceilings, a deep open plan, hard floors — are the same qualities that make it reverberant. Nothing in the shell absorbs anything. Partitioning alone does not fix it: sound travels over a partition that stops at a suspended ceiling and through a floor slab with no resilient layer. It is cheaper to design the absorption and the separation together with the layout than to add treatment after the first month of complaints.
A floor area cannot price a fit-out.
We walk the floor, look at what is already there and what can be kept, and tell you what the access regime does to the programme. Free, and it is the only honest way to put a number on Clerkenwell space.
