Ascot

If you’re planning an extension, renovation or new house in Ascot, understanding the site and local planning context early on makes a significant difference.

​

I work on residential projects across Ascot, including Sunninghill and Sunningdale, helping homeowners improve and extend their properties or develop new homes. In this part of Berkshire, the best results usually come from a careful reading of the site — particularly plot size, landscape setting and neighbouring context — rather than simply maximising built form.

​

Ascot falls within the Royal Borough of Windsor and Maidenhead, alongside parts of nearby Bracknell Forest. Planning decisions are shaped by the Borough Local Plan, the Ascot, Sunninghill and Sunningdale Neighbourhood Plan, and more recent guidance such as the Ascot Placemaking SPD. Together, these place strong emphasis on character, landscape and the quality of residential environments.

Residential projects in Ascot

Ascot and its surrounding areas are known for larger plots, mature landscaping and a more spacious suburban character. Typical projects include:

​

  • Extensions and full house refurbishments

  • Replacement dwellings

  • New build houses on generous plots

  • Alterations to improve layout, light and connection to the garden

​​

In many cases, there is significant potential within a site, but proposals need to be carefully balanced to sit comfortably within their surroundings

Planning permission in Ascot

Planning in Ascot is often more sensitive than it first appears, shaped by the character of the area and the nature of larger, landscaped plots.

​

The Ascot, Sunninghill and Sunningdale Neighbourhood Plan and Placemaking SPD place strong emphasis on design quality, spacing and the retention of landscape character, which can limit how much development is appropriate, even on generous sites.

​

Trees are a key factor, with mature planting and Tree Preservation Orders often influencing layout and construction. Proposals are also expected to respect the wider landscape setting and avoid overdevelopment.

Green Belt or countryside designations may apply on the edges of Ascot and Sunningdale, while ecology and biodiversity can become relevant on greener sites.

​

Depending on the site, supporting information such as tree surveys, drainage or ecological input may be required.

A Practical, Local Approach

Every project is different, but the aim is the same — a well-considered design that works and stands a good chance of approval.

​

Working in and around Ascot means understanding how to balance design ambition with planning sensitivity, particularly in relation to trees, landscape and the character of the area.

​

If you’re considering a project in Ascot, Sunninghill or Sunningdale, I’m happy to talk things through and give you a clear idea of what’s possible.
