One Studio. One Contract. One Team.
Most Gerrards Cross flats are in purpose-built blocks or over the shops of the centre. Refurbishing one is a matter of reading the lease, respecting the structure you share with neighbours and keeping to the fire strategy of the common parts.
At the 2021 Census the Gerrards Cross ward had 620 households in purpose-built blocks of flats, 18.2% of the total. A further 40 lived in converted or shared houses, including bedsits, 21 in other converted buildings such as former schools or churches, and 67 in commercial buildings, over a shop or an office for example.
Many of the blocks are recent. The conservation area appraisal records flats replacing large houses, particularly along Packhorse Road, and the neighbourhood plan notes a run of developments providing one- and two-bedroom flats. The 2017 Townscape Character Study maps an apartments character type in the town, one it ties to town centre locations, with simple forms and brick the dominant material.

Blocks, parades and conversions in Gerrards Cross
Above the shops, the flats are older. The appraisal finds flats and offices on the upper floors of the shopping parades, three-storey parades on Packhorse Road with flats over the shops, and Marsham Chambers on Station Road, built in 1933 as a mixed-use building and now shops below with flats above, three storeys in all.
Those parades belong to the commercial centre of the Centenary conservation area, designated on 28 April 2009, where the original doors to offices and flats over the shops were recessed. The 2017 study notes that tightly formed centres such as this one may go up to 4 storeys.
The study describes its apartment type as 3-5 storey blocks served by on-street parking or parking courts, some older blocks with a few individual garages, and landscaped strips of grass or planting between building and road. Those shared spaces are where skips, deliveries and the protection of planting have to be agreed before a refurbishment starts.
Some flats are carved from older buildings. On the Common, the former vicarage has been divided into houses and apartments and sensitively restored. In the two areas of exceptional character, by contrast, saved policy H10 normally resists the conversion of single dwellings into flats.
The neighbourhood plan's consultation found over 70% of the community saw no need for more flats in Gerrards Cross, which puts the emphasis on improving the ones the town already has.

The lease, the freeholder and planning for a flat
Most flats are leasehold, held from a landlord often called the freeholder, and it is the lease rather than the council that decides whether alterations need permission and whether you or the landlord answer for repairs and noisy neighbours. Ignore its conditions and you can be taken to court and made to pay for damage.
Householder permitted development stops at the door of a block: the planning meaning of a dwellinghouse leaves out any building containing flats and any single flat inside a building. Work kept inside the flat is still not development, but a change that materially alters the outside of the building, such as windows of a different design, needs planning permission.
On the parades, the appraisal singles out surviving original details such as the recessed doors to the flats above, so a replacement entrance door or window there is drawn to the original pattern.

Entrance doors, common parts and sound between flats
Approved Document B has separate guidance for flats, covering escape within the flat and on through the common parts to a place of safety. It is built on keeping a fire inside the flat where it starts while the shared escape routes stay relatively clear of smoke and heat, which is why the entrance door matters: where it opens onto a space in common use it should reach E 30 S, and every such fire doorset needs a self-closing device.
If a flat has a storey more than 4.5m above ground, the guidance offers a protected entrance hall of at least REI 30 that serves every habitable room, or a layout in which the travel distance from the entrance door to any point in any habitable room stays within 9m. Removing hall partitions to open up the plan is tested against both.
Under Approved Document E, a flat has to give reasonable resistance to sound from the rest of the building and from adjoining buildings, and a building that comes to contain a flat for the first time has undergone a material change of use. Where floors are relaid, the guidance credits a soft covering with cutting impact sound at source and warns against hard, non-resilient finishes bonded rigidly to the floor base.
A floor or other structure separating parts of a building with different owners, as between flats, may count as a party structure, and work on it can then require notice to the owner on the other side.
Higher-risk buildings, which need approval from the Building Safety Regulator before work begins, are at least 7 storeys or 18 metres high. A block of the 3-5 storey kind the study describes falls below that line, so ordinary building control applies, though we confirm the height of yours.

Refurbishing a Gerrards Cross flat
Flat refurbishments in Gerrards Cross are taken on by our London team: in-house architects and designers, structural engineers wherever a wall or floor is altered, and Hampstead Chartered Surveyors & Building Consultancy for the survey and the papers a freeholder will want to see. Building regulations work goes to Buckinghamshire Council's building control service or a private registered building control approver, and anything needing planning permission is decided by Buckinghamshire Council.
We read the lease before we draw, list the alterations that need the freeholder's or managing agent's consent, and prepare the drawings and method statement they ask for.
Access times, deliveries, protection of the stairs and lift, and the noisiest tasks are agreed with the building's management before work starts, and the neighbours above, below and beside are told what to expect.
The job is run from our Finchley Road studio in Hampstead, NW3; there are no premises of ours in Buckinghamshire, and one project manager is the contact for you and for the building's management.
Outside Gerrards Cross, and in London rather than Buckinghamshire: Project example: Hampstead, NW3. That project of ours was a full renovation of a three-bedroom, two-bathroom flat in Hampstead, as its case study records.

Flat Refurbishment in Gerrards Cross: Questions
Do I need my freeholder's consent to refurbish a flat in Gerrards Cross?
Often you do. Most flats are leasehold, and the lease says whether alterations need permission and who answers for repairs. We read it before drawing anything, because breaking its conditions can mean court and an order to pay for any damage.
Which flat works in Gerrards Cross need building regulations approval?
Building regulations approval is separate from planning permission and can be needed for alterations such as replacing windows and doors, installing a bathroom with plumbing and changing electrics near a bath or shower. An installer registered under a competent person scheme signs off its own work; the rest is checked by Buckinghamshire Council's building control service, or by a private registered building control approver you appoint.
What sound insulation rules apply when a flat's floors are changed?
Approved Document E requires a flat to give reasonable resistance to sound from the rest of the building and from adjoining buildings. When floors are relaid, its guidance favours a soft covering, which cuts impact noise at source, and warns against non-resilient finishes rigidly bonded to the floor base. The lease may set its own conditions, so we check both.
Do window changes to a flat in one of Gerrards Cross's conservation areas need permission?
Usually, if the outside changes. A flat has no householder permitted development rights, so new windows that materially alter the building's appearance need planning permission whether or not the block stands in a conservation area, while repair that leaves the appearance unchanged does not. Replacement windows also fall under the building regulations unless the installer is registered under a competent person scheme.
How do you scope and quote a flat refurbishment in Gerrards Cross?
From a survey of the flat, a reading of the lease and the building's requirements for contractors. The written scope lists each room's work, the services, fire doors and floor build-ups, the consents and approvals and the access arrangements, and the quote prices every item.
Are there many flats in Gerrards Cross?
Enough to matter. The 2021 Census counted 620 households in purpose-built blocks of flats in the Gerrards Cross ward, 18.2% of the total, and 67 in commercial buildings, over shops among them. The appraisal places flats above the centre's parades and in newer blocks that replaced large houses along Packhorse Road.
