A Covent Garden kitchen project begins by establishing where the waste can actually go. In a flat the single most consequential fact is the position of the existing soil stack or service riser, because a kitchen sink, dishwasher and washing machine all need a waste run that falls to it at a workable gradient. Move the kitchen to the other side of the flat and that run may cross the whole floor plate, eating into ceiling void or forcing a raised floor that then fights door heights and level thresholds. We survey the stack, the riser and the existing falls first, and let that geometry, rather than the ideal furniture layout, set the realistic positions a kitchen can take. In a historic building the riser is often shared with the flats above and below, so its capacity and any freeholder rules on connecting to it matter as much as the distance, and we establish both before a layout is fixed.
Extract and ventilation are the second constraint, and in a mixed-use building they are rarely simple. A relocated hob needs mechanical extract, and in a flat you cannot always duct straight out through a protected or shared elevation. The options — recirculating filtration, a ducted run to an existing louvre, or a new external termination — each carry consequences: recirculation limits the appliances you can serve, a long duct run needs void and loses performance, and an external flue may need both freeholder consent and, if it shows on the elevation, planning within a conservation setting. We resolve the extract strategy at the same time as the layout, because it frequently decides where the hob can sit. Ventilation to the room as a whole matters too: building regulations set requirements for background and purge ventilation, and a deep flat with few external windows can make a naturally ventilated open kitchen harder to achieve than the plan first suggests.
Acoustic separation is what makes a Covent Garden kitchen honest work rather than a suburban fit-out. Many of these flats sit above shops, restaurants or other flats, and a kitchen is a source of impact noise — footfall on hard floors, appliance vibration, waste flowing through the stack. The lease almost always requires that the separating floor is not made worse, and building regulations set sound-insulation standards between dwellings. We specify a floating or resilient floor build-up, isolate appliances and box the stack acoustically, and we coordinate that build-up with the drainage falls and the finished floor level so the three do not collide once construction starts. Where a commercial kitchen or plant sits below, the separating construction may also carry fire-resistance and grease-duct implications, so we confirm the existing floor make-up and the lease requirements before specifying anything that alters it.
Opening up the plan is where structure enters. Turning a closed galley into a kitchen-living space usually means removing a wall, and in a historic subdivided building it is rarely obvious which walls are load-bearing, which are later partitions and which conceal a stack or a structural pier. A structural engineer designs any beam, and where it bears into a separating wall shared with another flat the Party Wall etc. Act 1996 is engaged. We identify the load path and the notifiable neighbours early, because a beam that has to bear into a party wall changes both the programme and the consents, and neither should surface after the lease application has gone in. Head height is the other quiet limit: a downstand beam or a boxed service run reduces the ceiling locally, and in older upper-floor flats where the storey height is already modest, that can decide whether an open-plan move is comfortable or oppressive.
None of this proceeds without the freeholder. A Licence to Alter is the leaseholder's formal permission from the freeholder or management company to carry out the works, and moving wet services, altering structure and changing the separating floor are precisely the works a lease reserves. The freeholder's surveyor will want drawings, specifications and often method statements, and the licence commonly sets conditions on hours, protection of common parts and making good. We prepare the drawing set the licence application needs, coordinate with the managing agent, and sequence the lease consent alongside any building regulations and, where required, planning or listed building submissions so the approvals run in parallel rather than one after another. Leaseholders often underestimate the freeholder's timescale, which is not fixed by statute the way a planning determination is, so we allow for it in the programme and give the surveyor a complete, unambiguous set the first time to avoid the rounds of queries that stretch a licence out for months.
The route through, then, is deliberately ordered for a flat rather than a house. We survey the flat, fix the stack, riser, extract path and structure, and test where a workable kitchen can actually go; we agree the acoustic and drainage build-up; we confirm whether the address falls to Westminster or Camden and whether listing or the conservation area brings any element into planning control; and we produce the drawings that serve the Licence to Alter, the building regulations submission and any planning application together. We do not promise approval or a particular freeholder outcome — but we make the technical case defensible and the consents legible before anyone commits to a build. That order protects the client from the two most common flat-kitchen failures: a beautiful layout that cannot be drained or extracted, and a scheme that stalls because the lease consent was treated as an afterthought rather than a governing constraint. Getting both right at the drawing stage is what makes a Covent Garden kitchen buildable.
