Flat refurbishment near Parliament Hill and the Vale of Health
Architects, Engineers & Builders Under One Roof.
One Studio. One Contract. One Team.
Hampstead Chartered Surveyors & Building ConsultancyFlat renovation in converted houses, late Victorian terraces and post-war blocks around Parliament Hill and the Vale of Health, starting from the lease and the parts of the building you share.
Many flats near the Heath are in houses that were divided later, and Camden's South Hill Park statement links those conversions to pressure for basements, roof extensions, rear additions and lost garden space.
So a flat brief here starts with two documents: the lease, and the conservation area guidance for the building.

What the Lease Allows
Planning permission and building regulations approval do not settle the lease: LEASE explains that, under many leases, the landlord must also agree to the alterations.
Other clauses matter as well. LEASE points to leases that insist on carpet throughout, which would stop a new wooden or laminate floor.
LEASE adds that a landlord is not allowed to charge a premium for consent to non-structural alterations, whatever the lease says.
We read the alterations, flooring and nuisance clauses with you before any layout is drawn.

Changes to the Outside of a Converted House
Householder permitted development does not cover a building divided into flats, or a flat within it, according to the government's technical guidance.
On land within Camden's Hampstead Article 4 direction, a flue or soil pipe that passers-by can see from the street is no longer permitted development.
Camden's Home Improvements guidance prefers new pipework on the side or back of the building, gathered together in a discreet run.

Party Walls, Floors and the Flats Around You
Before working on a party wall or party structure, or building at the boundary, the owner must notify the neighbours, GOV.UK says.
If they cannot agree, a surveyor is appointed, jointly or one each, to settle the work, its timing and who pays; no owner may be their own surveyor.
Party wall agreements are a different thing from planning permission and from building regulations approval.
LEASE asks leaseholders carrying out work to consider other occupiers, avoiding excessive noise and keeping corridors, stairs and shared areas clean and clear.

Surveying the Flat Before the Layout
We lift sample floorboards to see the joists and the pipes beneath them, test the walls for damp at garden level, and look at the wiring, the boiler and its flue before a new layout is drawn.
In a converted house we also trace which pipes and cables serve other flats, so the design does not cut a neighbour's supply, and we note where the floor build-up will meet the common stair.
Where the work needs building regulations approval, it can come from Camden's building control department or a registered private approver, and GOV.UK notes that compliance certificates may be needed when the flat is sold.

Flats in Listed Buildings
Ten buildings on the west side of South End Road and a row of early 19th-century cottages in the Vale of Health are listed, according to Camden's Hampstead statement.
Inside a listed building, Camden protects every part, interiors and later additions included, and consent is applied for separately from planning.
Expect Camden to resist changes that strip out historic fabric or hide how the rooms were first laid out; the council also holds the owner responsible for keeping a listed building in repair.
For a flat in a listed building, cornices, doors and fireplaces are photographed before the layout is discussed, so the consent drawings can show what is kept.

Deliveries and Working Hours
Camden lets noisy work go ahead without authorisation on weekdays between eight in the morning and six in the evening, and on Saturday mornings until one.
A skip on the road needs a Camden licence requested by the skip firm itself, five working days ahead at the least, while a bay suspension has to be booked online 17 days or more in advance.
In a shared building we agree with the managing agent where materials are stored and how the stair is protected, and we keep the common parts clear at the end of each day.

Questions about renovating a flat near the Heath
Do I need my landlord's permission as well as planning permission?
Quite possibly. The two are separate, and LEASE notes that a lease can make the landlord's agreement a condition of any alteration.
Can my landlord charge for consent to alter my flat?
Not a premium where the alterations are non-structural, LEASE says; the law forbids it regardless of the lease.
Can I put a new flue or soil pipe on the front of the building?
On land covered by Camden's Hampstead Article 4 direction, one visible from a road or public space now needs planning permission, and Camden prefers pipes at the side or rear.
Will my neighbours need party wall notices?
Yes, where the job affects a shared wall or floor that counts as a party structure: GOV.UK requires notice before work starts.
Is my building listed?
Check the National Heritage List. Camden's statement records listed houses on South End Road and listed cottages in the Vale of Health, and listing reaches inside the building.

Flats in converted houses and post-war blocks near Parliament Hill and the Vale of Health
Camden's South Hill Park statement records that converting former houses to flats and maisonettes has brought development pressures, among them basement excavation, roof extensions and changes to roof profiles, rear extensions, the loss of garden space and the loss of elevational detail. It names Oliver Court as a post-war development of flats with recessed balconies.
In the Vale of Health, Camden's Hampstead statement describes Atheneum Hall, at the end of a curving terrace of late 19th-century houses, as a 1950s four-storey block of flats with a semi-basement and a set-back fifth floor.
For a flat in any of these buildings, we read the alterations clauses of the lease with you and check which conservation area applies to the address before the layout is drawn.
