House Extension Drawings in Tolworth |

No Article 4 Direction covers Kingston upon Thames, which keeps the Tolworth permitted-development route open on unlisted houses. In Tolworth the streetscape argument usually decides the case before the numbers do, because the area is 1930s semi-detached, post-war flats. Conservation status changes the Tolworth route entirely — Kingston Old Town being the usual case among the 22 designations in Kingston upon Thames. We plot the Tolworth site against the designation before quoting.

Article 4 directions are checked street by street in Tolworth; the borough-wide answer is rarely the whole answer. The 1930s semi-detached governs the numbers on a Tolworth site: rear wall, eaves, and how far a ridge can rise beside Tolworth Tower. The borough policy layer over every KT5, KT6 address is set out on Kingston upon Thames planning. The Tolworth survey then carries into loft conversion drawings in Tolworth if the project runs on to construction.

Most Tolworth delay happens before the clock starts: Royal Borough of Kingston upon Thames takes one to two weeks to validate, and an incomplete pack goes to the back of the queue. No Tolworth design work starts until the measured survey is complete.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

A Tolworth case only reaches committee if it draws significant objection. The KT5 pack is issued at 1:100 and 1:50 with a 1:1250 location plan.

Neighbour comment is what shapes most Tolworth decisions; policy rarely decides alone. Levels between front and rear of a Tolworth house are recorded, not assumed.

Shared walls are the norm in Tolworth; the notice period is not optional. Once consent is granted, architectural drawings follows for the KT5 property.

Tolworth is characterised by 1930s semi-detached, post-war flats, concentrated across KT5, KT6 in the Surbiton / Tolworth area. Tolworth is not uniform, but the 1930s semi-detached recurs often enough across KT5, KT6 that the structural pattern is predictable once measured. For a typical Tolworth house, 1930s semis here have the deepest rear gardens in the area, which is why the 6 m and 8 m larger-home prior approval route gets used so often. That is the Tolworth constraint Kingston Council will look for. Kingston Council judges massing against the established Tolworth rhythm — the eaves and ridge lines running past Tolworth Tower.

Going down in Tolworth is assessed on ordinary grounds — KT5 ground conditions and drainage do more to shape the scheme than policy does. One visit to the Tolworth address covers planning permission for KT5 properties and building regulations drawings too.

What the Tolworth drawing pack contains

For a KT5, KT6 address the deliverables are fixed, not open-ended.

• existing and proposed ground-floor plans for the Tolworth property
• proposed rear elevation
• long section through the extension
• site and block plans
• party wall position drawing

Streets and landmarks we survey around Tolworth

• Horton Country Park — terraced rear elevations — the Horton Country Park party wall position is drawn first.
• Bushy Park — shared flank walls, so Bushy Park party structure notices go out before work starts.
• Morden Hall Park — side returns where the 45-degree amenity test decides how far a Morden Hall Park extension goes.
• Worcester Park — side returns where the 45-degree amenity test decides how far a Worcester Park extension goes.
• Richmond Park — terraced rear elevations — the Richmond Park party wall position is drawn first.
• Sandown Park — front-to-back level changes that drive the Sandown Park section drawings.
• Tolworth Tower — massing on adjoining KT5 plots is tested against it.
• Roman Catholic Church — proposals within its setting are drawn with the context elevation included.
• Hollyfield School — a Tolworth roof extension is judged against the datum it sets.
• Glyn Grammar School — massing on adjoining KT5 plots is tested against it.
• Tolworth Girls' School — schemes in view of it attract closer officer scrutiny.
