Define the boundary of the work
Bring the lease information and any managing-agent requirements you already have. We need to understand which elements belong to the flat, which are managed collectively and where access depends on another party. This is particularly relevant when the design touches a shared service, an entrance door, a structural element or external equipment. The renovation scope should show those interfaces clearly, rather than making them somebody else's problem after the interior design has been agreed.
Council jurisdiction also needs an address check. Southwark's Kennington Park Road conservation area meets Lambeth at Kennington Park Place. A Kennington or SE11 description therefore does not establish the planning authority for every flat.
Work within a converted house without assuming a blank plan
Where your Kennington flat occupies part of a house, start with the rooms and openings inherited from that arrangement. Record any internal route or cupboard shared with another dwelling and clarify the boundaries before considering removal. We test how you enter, cook, store belongings and reach the bathroom within those limits. A useful design can work with existing divisions, rather than start from an open rectangle that would only exist after uncertain alterations.
A proposed layout is tested with actual furniture sizes. A room labelled as a bedroom on a plan still needs to hold the intended bed, storage and circulation. A dining area needs space when its chairs are occupied. We draw these uses together with the position of windows, radiators and service access. When options compete, the choice can then be discussed in terms of how the flat will function, rather than how empty it looks in a rendering.
Investigate changes that reach beyond one room
Moving a kitchen or bathroom can affect the entire refurbishment. Before pursuing that arrangement, identify the connection routes, the spaces that would need opening up and any shared systems involved. The useful decision is whether the change can be supported by a complete design and the necessary permissions. If that cannot be established, retaining the existing service locations can become a positive design constraint, with improvements focused on storage, circulation and fit-out.
We also review floor and ceiling changes across room boundaries. The chosen build-up influences thresholds, door clearances and the relationship with fixed furniture. Any acoustic or fire-related requirement is assessed by the appropriate designer for the actual assembly; a product label is not treated as proof that the finished construction will meet the project's requirements. Installation details and inspection points should be understood before covering up the work.
Check the route for external alterations
Southwark distinguishes applications for alterations to a flat from the householder route used for single houses. Government householder permitted-development guidance also excludes flats. Where your proposal involves external changes, establish the correct planning route instead of borrowing assumptions from a neighbouring house project.
Windows, ventilation terminals and other visible elements are marked separately on the design. That makes it possible to discuss their appearance and approval requirements without confusing them with internal decoration. Where an existing detail is to remain, record that too. We keep the documents for landlord or management consent distinct from planning and other approvals, so that acceptance by one party is not mistaken for permission from everyone involved.

Organise deliveries and shared access
A flat's access route can determine how an installation is assembled. Measure stairs, landings and doors against the largest proposed components before ordering them. We identify where materials may be received and how common spaces are protected, with particular care at corners and entrance thresholds. The same route needs to work for removing existing fittings. A practical plan considers both directions of travel and keeps neighbours' access visible throughout the discussion.
Communication is most useful when it is specific. Agree who is contacted about building access, what arrangements need advance notice and where questions should be recorded. Within the flat, distinguish rooms available for use from work areas and storage areas. If occupation during the refurbishment is being considered, the decision should follow the proposed scope and access plan. It should not depend on treating a kitchenless or bathroomless arrangement as automatically manageable.
Complete the flat as a connected home
Finishes should be reviewed across the whole plan. Flooring transitions, door hardware and lighting controls can make adjacent rooms feel coherent without requiring every surface to match. We use samples to test those relationships in the available light. Storage is designed around what belongs in each room, with access to services preserved. The result should be convenient at the entrance, in the utility corners and behind cupboard doors, not only in the main living space.
At handover, walk through the flat in the same sequence as an ordinary day. Check entrance storage, appliance clearances, bathroom operation, lighting and access to equipment. Record outstanding details by room and keep the approved drawings alongside relevant completion information. If future work is contemplated, mark what was left outside this scope. That gives the next project an accurate account of what changed and what remains, instead of relying on recollection.
Before work begins
Flat refurbishment in Kennington: questions
Why check the authority before altering a Kennington Park Road flat?
Southwark's Kennington Park Road conservation area adjoins Lambeth, so the location must be checked before selecting a planning route. For your flat, identify the exact building and proposed external changes first. Relevant correspondence and existing approval records can then be assembled for the correct authority rather than inferred from an SE11 label.
Does owning a share of the freehold remove all approval questions?
The ownership arrangement needs to be read with the documents governing the building and the proposed work. We do not infer an alteration right from that description alone. Establish who can authorise changes and what evidence they require, then keep those decisions with the project information.
Can a Kennington flat rely on householder permitted-development rights?
Government guidance excludes flats from householder permitted-development rights. If your refurbishment includes external alterations, establish the applicable route for the flat itself. We separate that question from the interior fit-out and from any landlord consent, so a cabinet or finish decision does not conceal an unresolved external element.
Will the refurbishment include common parts?
Only if that work is explicitly agreed and authorised by the relevant parties. We identify any necessary interfaces with shared entrances, services or structure, but they do not automatically become part of an interior flat refurbishment. The distinction should be clear in the scope and access arrangements.
How do we avoid redesigning the flat during installation?
Resolve the important dependencies first: layout, service routes, floor levels and the dimensions of fixed equipment. Record your product choices and design revisions in one place. If investigation reveals a material difference, review it openly before proceeding; a controlled change is more useful than an unrecorded adjustment on site.
