Hampstead Chartered Surveyors & Building ConsultancyMost Maida Vale flats are in red-brick mansion blocks of around 1900 or in Victorian pairs divided long ago, and the lease shapes the job as much as the plan does.
Early mansion blocks of flats stand around Elgin Avenue, in the red-brick northern part of the district, Westminster's leaflet records.
Whether the flat is in a purpose-built block or a converted house, the lease and the managing agent are treated as part of the design from our first visit.

Where the mansion blocks came from
Open fields still left in 1900 are now covered almost entirely by mansion blocks, the conservation area directory notes.
Morshead and Grantully Roads, beside the recreation ground, were laid out for flats in 1898 and 1899, followed by Widley and Wymering Roads in 1901.
After 1900 most new building was mansion blocks, which also replaced many of the villas on Edgware Road.
They were built in the Queen Anne Revival manner: red brick, panels of moulded brick and wrought iron railings.
Before choosing a floor finish in a block, we measure how much sound already passes between storeys and check whether the floor inside the flat is timber or solid.

Flats in divided Victorian houses
Splitting houses is an old habit here. Westminster's 1966 schedule lists 1840s pairs of brick and stucco on the west side of Warwick Avenue as converted into flats even then.
Several flats sit in listed buildings, since the leaflet's count of listed buildings takes in flats as well as houses and villas.
Recombining two flats into one home brings Westminster's housing quality policy to bear.
A converted house usually means one roof, one entrance and one soil stack shared between several owners, so we map which pieces belong to your flat before suggesting a single change.

Reading the lease before the layout
A lease should mark out the demised premises, which are yours, from the retained premises, which stay with the landlord; LEASE is clear the second kind cannot be altered without permission.
So a knock-through in a structural wall the landlord owns, or an extension into outside space the landlord owns, needs that permission first.
Where alterations are allowed with consent, a landlord may not refuse without a reasonable ground, yet that safeguard falls away for work to the landlord's own parts.
A licence can carry conditions: approving who does the work, proof that it meets building standards, and an entry on the lease recording it.
Fresh written permission may be needed for each alteration, and work done without it can put you in breach even if a former owner did it.
We assemble the pack a managing agent usually wants, with drawings, a method statement and a sequence of works, and the start date waits until the licence is signed.

Windows, the entrance door and the outside of the block
New windows in a flat need planning permission when they alter the building's look, through a new frame size, opening method or material, the Environment SPD explains.
When the landlord owns those windows, or the external doors, the landlord's permission is needed to replace them too.
The door into the flat itself is normally a fire door, and LEASE calls changing it safety-critical.
Westminster's Policy 45 resists changes that would upset the regular rhythm and grouping of a terrace or block.
If a window cannot be saved, the replacement copies the pattern of its neighbours in the block, and the drawing goes to the managing agent with the request for consent.

Heating, hot water and floors
Some leases restrict changing the boiler system, drilling the external wall for a flue, or fixing a heat pump to the outside.
Westminster's SPD notes that leaseholders have less room for retrofit than freeholders and must get the landlord's consent.
A lease that requires carpet can stop a timber or laminate floor going down.
Where hard floors are permitted, we float them on a resilient layer with a gap at the skirting, so the flat below hears as little as possible.

Sound, smell and the flats around you
To keep noise and cooking smells inside the flat, we put acoustic mineral wool in any wall or floor we open, and specify a ducted or recirculating hood to suit what the lease allows.
Doors between rooms are hung with smoke and acoustic seals where the layout puts a bedroom beside a living room or a neighbour's hallway.
Working inside a shared building
LEASE reminds leaseholders to keep noise reasonable and leave corridors, stairs and shared areas clean and unobstructed.
Under Westminster's Code of Construction Practice every contractor should respect working hours, limit impact and tell neighbours what is happening.
Common stairs and lift cars are lined before work begins, materials go up at agreed times, and the entrance hall is cleaned at the end of each day.

Questions about refurbishing a Maida Vale flat
Can my landlord say no to my alterations?
Only on reasonable grounds where the lease allows alterations with consent, and not even that limit applies to work on the landlord's own parts.
Will replacement windows need planning permission?
Yes, if they change how the building looks, for instance through a new frame size, opening or material.
Am I allowed timber floors?
Read the lease: a carpet clause can rule them out.
Do I own the windows and the roof above me?
The lease decides; whatever the landlord retains cannot be changed without permission.
Can two flats be joined into one?
Westminster's housing quality policy applies when flats are merged, so the council needs to be part of it from the start.
