Architectural Drawings in Hayes | Fixed-Fee Plans

No Article 4 Direction covers Hillingdon, which keeps the Hayes permitted-development route open on unlisted houses. Hayes reads as 1930s semi-detached, post-war, and that character is precisely what a Hillingdon Council case officer tests a proposal against. A UB3 property inside Ruislip Village loses part of its permitted development and generally goes to Hillingdon Council in full. Designation status for the UB3 address is established first.

Before drawing anything for Hayes, we check Article 4 directions against the UB3 boundary. On Hayes stock the constraint is physical before it is planning: the 1930s semi-detached fixes the rear wall line and the Hayes & Harlington roofline caps the ridge. The borough policy layer over every UB3, UB4 address is set out on Hillingdon planning. The Hayes survey then carries into building regulations drawings in Hayes if the project runs on to construction.

Hillingdon Council will not register a Hayes application until validation completes. A surveyor measures the Hayes property before any UB3 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.

Expect a site visit to the Hayes property during the consultation period. Drawings for Hayes are supplied print-ready and in the format London Borough of Hillingdon accepts.

Neighbour comment is what shapes most Hayes decisions; policy rarely decides alone. The Hayes survey records every opening, level change and structural wall.

Because Hayes houses generally share walls, budget time for party wall notices alongside the UB3, UB4 application. Once consent is granted, loft conversion drawings follows for the UB3 property.

Hayes is characterised by 1930s semi-detached, post-war estates, concentrated across UB3, UB4 in the Hayes / Harlington area. On Hayes plots, structure follows the 1930s semi-detached that is already there. Reading that across to Hayes stock: 1930s semis here are dimensionally consistent, so the survey is quick and the drawings come back inside the shorter end of the window. On Hayes plots that shows up in the section drawings. Height on a Hayes proposal is measured against its neighbours, not against a policy number; the Hayes & Harlington terraces set that datum.

Lower-ground schemes in Hayes answer to neighbours and groundwater. A Hayes survey done once feeds house extension drawings for UB3 properties and planning permission later.
