Patios & Decking in Old Windsor, Berkshire
What changes here.
Patios in Old Windsor tend to follow the same divide as the driveways. Gardens within the village envelope, off Straight Road and around the church, generally sit on ground that drains in a fairly ordinary way. Gardens nearer the Thames, or backing onto the water meadows and the edge of Windsor Great Park, sit on ground with a winter water table high enough that a thin bedding layer will trap moisture under the slabs and push it back up through the joints within a season or two. We ask where a garden sits relative to the river before recommending a build-up, rather than specifying the same patio for both.
Patios & Decking ground conditions in Old Windsor
On the drier ground further from the river, a conventional full-bed system on a compacted sub-base performs well with standard falls. Closer to the Thames, we grade the falls more aggressively and build in proper drainage so water moves away from the house rather than sitting against the paving through a normal Berkshire winter. Decking on the wetter plots gets the same treatment — posts and joists founded for ground that stays damp for months, not just for an occasional wet weekend, with timber and fixings specified accordingly.
Planning and permissions in Old Windsor
Ground-level patios are permitted development for the great majority of Old Windsor gardens, since the village's Green Belt designation applies to the land surrounding the settlement rather than to ordinary hard landscaping inside a garden boundary. The exceptions worth checking at survey are plots that back directly onto Windsor Great Park, where the boundary itself is Crown Estate land with habitat designations along parts of its edge, and any protected trees on the older, more established gardens near the village centre. We confirm both before design work starts rather than after materials are ordered.

Patios & Decking in Old Windsor FAQs
In Old Windsor, specifically.
A full-bed system with real falls rather than a thin bedding layer, graded to move water away from the house. On gardens closer to the river, where the water table stays high through winter, that fall is more generous than a standard patio spec would call for, because the paving cannot rely on the ground underneath to take the water away on its own.
Yes, with the boundary treated as its own question first. The Park is Crown Estate land, and parts of its edge carry habitat designations, so we confirm ownership and any constraint on the boundary itself before the patio or deck design is finalised, and keep the build well clear of the edge while work is under way.
It can be, provided the substructure accounts for it. We found posts and joists on foundations sized for ground that stays wet for a good part of the year on the plots nearer the river, rather than the drier-ground assumption a standard deck spec is built around, and specify timber and fixings rated for sustained moisture rather than occasional rain.
Only if the existing base is unsound. We check the existing surface for level, drainage and any settlement at survey. A sound, well-drained base can often be extended or built onto directly; one that already ponds or has moved, particularly on the wetter ground nearer the river, is not worth building onto, and we say so rather than lay new paving over an old problem.
