Edwardian + Victorian riverside. Planning authority: Elmbridge Borough Council.
We prepare architectural drawings across Walton-on-Thames and the surrounding area — Walton-on-Thames, Hersham border, Ashley Park and the riverside and the streets between them. The stock here is largely Edwardian and Victorian riverside houses, 1930s semis and later suburban estates, and we draw for every one of those types for submission to Elmbridge Borough Council.
Walton sits along the Thames with parts of the town in Flood Zones 2 and 3, so riverside plots need flood-risk sequential and finished-floor-level checks, while the Ashley Park conservation area adds character controls handled by Elmbridge Borough Council. Whichever route your address falls under, we confirm it free at the measured survey and design to match the local Surrey streetscape — from period rear and side-return extensions to rear-dormer and mansard loft conversions.

We research the council's Local Plan and recent decisions before drawing, and we hold a 98% first-time approval rate across our work.

It depends on your exact address. Many single-storey rear and side-return extensions on unlisted houses fall under Permitted Development, but Walton sits along the Thames with parts of the town in Flood Zones 2 and 3, so riverside plots need flood-risk sequential and finished-floor-level checks, while the Ashley Park conservation area adds character controls handled by Elmbridge Borough Council. Listed buildings, flats and conservation-area properties always need full planning, decided by Elmbridge Borough Council. We confirm exactly which route applies to your home, free, at the survey.
