Building Regulations Drawings in West Drayton |

No Article 4 Direction covers Hillingdon, which keeps the West Drayton permitted-development route open on unlisted houses. In West Drayton the streetscape argument usually decides the case before the numbers do, because the area is 1930s semi-detached. Check Ickenham before assuming permitted development on a West Drayton house; Hillingdon designates 29 such areas. That check comes before anything else on a West Drayton job.

That check — Article 4 directions against the West Drayton property — happens on day one. Everything on a West Drayton scheme is measured from the 1930s semi-detached outward. The borough policy layer over every UB7 address is set out on Hillingdon planning. The West Drayton survey then carries into planning permission in West Drayton if the project runs on to construction.

Validation alone costs London Borough of Hillingdon one to two weeks even when the West Drayton pack is complete, and that queue — not the determination — is where most UB7 delay starts. A surveyor measures the West Drayton property before any UB7 design begins.

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.

Consultation responses on a West Drayton scheme are public and readable before the decision. West Drayton clients receive existing and proposed sheets in one indexed set.

The West Drayton consultation period is where a weak scheme is exposed. A West Drayton measured survey captures the roof structure as well as the plan.

Party wall procedure catches most UB7 owners late; on West Drayton stock assume it applies and serve in good time. Once consent is granted, loft conversion drawings follows for the UB7 property.

West Drayton is characterised by 1930s semi-detached, post-war, concentrated across UB7 in the West Drayton / Sipson / Harmondsworth area. Every West Drayton scheme starts from what is actually there: 1930s semi-detached, post-war, surveyed to the millimetre before a proposal is drawn. Applied to UB7 property: 1930s cavity walls here take standard full-fill or partial-fill detailing, which keeps the Part L calculation straightforward. That is the West Drayton constraint Hillingdon Council will look for. A West Drayton proposal that breaks the prevailing eaves line invites a refusal.

A UB7 dig turns on engineering more than on policy. house extension drawings for UB7 properties and architectural drawings build on the existing West Drayton survey data.

Streets and landmarks we survey around West Drayton

• Stockley Park — front-to-back level changes that drive the Stockley Park section drawings.
• Hans Place — closet wings that change how a rear extension meets the Hans Place back addition.
• Sir Allen Lane — gardens deep enough for the 8 weeks householder route on a Sir Allen Lane plot.
• Colne Valley Regional Park — shared flank walls, so Colne Valley Regional Park party structure notices go out before work starts.
• West Drayton station — sightlines from here are part of the Hillingdon Council character assessment.
