Covering Windsor
Windsor sits 16 miles east of Reading, with Slough 2 miles to the north and Egham 4 miles to the south-east.
Homes in the South East
The South East has a lot of 1930s and post-war semi-detached housing, well suited to rear extensions and hip-to-gable loft conversions, alongside period properties in conservation areas that need a more careful design.
