Loft Conversion Drawings in Eastcote | From £1,225

No Article 4 Direction covers Hillingdon, which keeps the Eastcote permitted-development route open on unlisted houses. Because Eastcote is 1930s semi-detached, the officer's assessment leans on streetscape impact around Eastcote Tube as much as on the numbers. A HA5 property inside Ruislip Village loses part of its permitted development and generally goes to Hillingdon Council in full. The designation map is read street by street in Eastcote.

We map how Article 4 directions bite across HA5 before a line is drawn. What can be built on a Eastcote plot is decided by the 1930s semi-detached — the original rear wall position first, the Eastcote Tube roofline second. The borough policy layer over every HA5 address is set out on Hillingdon planning. The Eastcote survey then carries into building regulations drawings in Eastcote if the project runs on to construction.

London Borough of Hillingdon takes one to two weeks to validate a Eastcote submission. The first visit to Eastcote is a measured survey — every room, every opening, every level change recorded on site.

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.

An officer report on the HA5 case is written after the consultation closes. The set is checked against the London Borough of Hillingdon validation list before it goes in.

London Borough of Hillingdon weighs material objections only — a Eastcote neighbour disliking the design is not one. Existing structure in the 1930s semi-detached is identified at survey, not guessed later.

Budget notice time on any Eastcote job touching a shared wall. Once consent is granted, house extension drawings follows for the HA5 property.

Eastcote is characterised by 1930s semi-detached, concentrated across HA5 in the Pinner / Eastcote area. The 1930s semi-detached that dominates Eastcote behaves differently from the borough average, and the drawings follow the building rather than a house type. For a typical Eastcote house, the 1930s hipped roof here needs a hip-to-gable before a rear dormer works, which pushes the volume calculation toward the 50 m³ permitted-development ceiling. On the 1930s semi-detached in Eastcote it sets the beam run. Hillingdon Council judges massing against the established Eastcote rhythm — the eaves and ridge lines running past Eastcote Tube.

No borough-specific basement policy applies in Hillingdon, so subterranean work at a Eastcote address is judged on amenity, drainage and structural grounds. Survey once, use it for every HA5 submission that follows.

Local landmarks that shape a Eastcote application

• Rayners Lane — closet wings that change how a rear extension meets the Rayners Lane back addition.
• Eastcote House Gardens — shared flank walls, so Eastcote House Gardens party structure notices go out before work starts.
• Bletchley Park — shared flank walls, so Bletchley Park party structure notices go out before work starts.
• Eastcote Tube — the surrounding 1930s semi-detached takes its scale from it.
• Mount Vernon Hospital — proposals in its setting are drawn with the Eastcote context elevation.
• Ealing Hospital — sightlines from here are part of the Hillingdon Council character assessment.
