The honest starting point for a Lancaster Gate refurbishment is that you are almost certainly refurbishing a leasehold flat inside a period building, not a house. That single fact reorganises the whole project. The controlling document is the lease, and the first task is to read it against the demise plan to see exactly what you own: the internal surfaces and partitions usually, but rarely the structure, the roof, the external walls or the shared risers and stacks. A scheme that assumes house-style freedom to alter anything will collide with the reserved parts, so we map what is inside your demise and what belongs to the freeholder before a layout is committed, because that boundary decides which walls can move and which services you may touch.
The approval that matters most is the Licence to Alter. The freeholder or managing agent grants it, and they will expect a technical package rather than a set of mood images: drawings of the proposed works, a method statement, structural information where anything load-bearing is affected, acoustic and fire evidence, and insurance and consultant details. Managing agents on stucco-fronted Lancaster Gate buildings can require method notes, insurance information and consultant letters before they release consent, and they can withhold it until the evidence satisfies them. The licence is a legal document that is negotiated and, in many buildings, engrossed by the freeholder's solicitor and surveyor at the leaseholder's cost, so the quality of the drawings you submit directly affects both how long it takes and how many conditions come back attached. We assemble that package deliberately so the licence application is a document the agent can approve, not a negotiation that stalls the programme for months.
Acoustic performance over the flat below is often the defining technical constraint. Replacing floor finishes, and especially moving a kitchen or bathroom, changes the impact and airborne sound reaching the apartment beneath, and most leases and managing agents set a required standard of resilient build-up. The catch is height: a resilient layer, screed or acoustic mat, and the new finish all consume floor-to-ceiling height that a period flat may not have to spare, and a raised floor has knock-on effects at thresholds, doors and the tops of windows. We resolve the floor build-up early, in section, so the acoustic requirement is met without an unworkable step at every doorway.
Relocating a kitchen or bathroom is really a drainage and riser problem before it is an interior one. Soil and waste have to reach the building's existing stack at a workable fall, and in a converted period building that stack is usually in a fixed position that belongs to the freeholder. Moving a wet room across the flat can mean long waste runs, boxed-in drops through the floor zone, or a pumped solution, each with acoustic and access consequences. Extraction and ventilation raise the same difficulty: routing a kitchen or bathroom vent to a shared riser, or finding a discreet termination that does not put a visible external outlet onto a stucco frontage, is often what limits where the wet rooms can sit. We coordinate the new sanitaryware and kitchen against the real position of the stack and the shared risers, and where a new connection is needed we treat the freeholder's consent to alter drainage as a gating item, not an afterthought.
Fire separation is the requirement that quietly reshapes a flat refurbishment. Each apartment is a compartment, and the walls and floor separating it from neighbours and from the common parts have to maintain their fire resistance; the flat entrance door is a fire door with a defined performance, and any opening formed in a compartment wall or floor has to be reinstated to the same standard. Building regulations require this, and in a stacked period building it is often the hidden cost of an open-plan aspiration. We identify the compartment lines at survey and detail every penetration, service riser and new opening so the compartmentation is maintained rather than compromised by the new layout.
Finally, the works have to be delivered through a building that other people live in. Access is through shared halls, stairs and often a single lift, and the managing agent will expect the common parts protected, deliveries and waste controlled, and working hours respected. Party-wall considerations can apply between flats where an opening is cut into a shared structure or new loads bear onto it, so notifiable neighbours are identified before work starts, and a schedule of condition to the adjoining flats protects both sides if a dispute arises later. We build these constraints — common-part protection, restricted access, party-structure notices, and the managing agent's method requirements — into the drawings and the specification from the outset, so the refurbishment is buildable within the realities of a shared, occupied period building rather than fighting them.
