Architects in Maidenhead — chartered,

Who decides a Maidenhead planning application?

The Royal Borough of Windsor and Maidenhead, a unitary authority. There is no second tier — Berkshire County Council was abolished in 1998 — so the borough is the sole planning authority, the building control authority and the highway authority for the town.

Statutory fees are national: £548 for a householder application, £274 for a Lawful Development Certificate, £610 for a new dwellinghouse, £249 for larger home extension prior approval, and no fee for listed building consent. Determination is eight weeks from validation for householder work.

What constrains building in Maidenhead?

The town is tightly bounded by Metropolitan Green Belt on almost every side, which is why Maidenhead grows by intensification rather than sprawl. Inside the Green Belt an extension is judged against whether it is a disproportionate addition over and above the original dwelling, and extensions built by previous owners count against that allowance. Replacement dwellings are tested against whether the new house is materially larger than the one it replaces.

The Thames runs along the eastern edge through Boulter’s Lock, Bray and Cookham, and Flood Zone 2 and 3 designations follow it inland further than most owners expect. Where they apply you will need a flood risk assessment, minimum finished floor levels and often flood-resilient construction; basements are frequently ruled out entirely.

Heritage is concentrated rather than blanket. Cookham village, Bray village and the older river frontages carry conservation-area status, and there is a scatter of listed buildings through the town centre and the surrounding villages. Much of the interwar and post-war residential stock north and west of the centre is undesignated, which is where permitted development still does real work.

What kind of work do we do in Maidenhead?

• Rear and wrap-around extensions on the post-war estates north of the town centre, where detached plots make the 4 metre permitted development depth and the 8 metre prior approval depth genuinely usable.
• Loft conversions and hip-to-gable schemes on the interwar semis, generally permitted development confirmed by a £274 certificate.
• Green Belt extensions and replacement dwellings in Cookham, Bray and the village fringes, where the volume comparison against the original house governs the scheme.
• Flood-zone design along the Thames corridor, where finished floor levels shape the section from the first sketch.
• Conservation-area alterations in Cookham and Bray, assessed on materials, window proportions and the village streetscene.
