Planning Permission in Biggin Hill | Fixed-Fee Plans

No Article 4 Direction covers Bromley, which keeps the Biggin Hill permitted-development route open on unlisted houses. Biggin Hill is 1930s semi-detached, rural fringe; near Biggin Hill Airport that context does most of the work in an officer report. A Biggin Hill address in Bromley Town or Chislehurst loses part of its permitted development, so we usually take the TN16 scheme to Bromley Council as a full application from the outset. Designation status for the TN16 address is established first.

The Biggin Hill Article 4 position is established at survey, before design. What the Biggin Hill building allows is established first; what Bromley Council allows, second. The borough policy layer over every TN16 address is set out on Bromley planning. The Biggin Hill survey then carries into architectural drawings in Biggin Hill if the project runs on to construction.

London Borough of Bromley takes one to two weeks to validate a Biggin Hill submission. Survey first: we measure the Biggin Hill property in person, then draw the existing plans, sections and elevations from that data.

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.

Most Biggin Hill householder cases are decided under delegated powers, not committee. Drawings for Biggin Hill are supplied print-ready and in the format London Borough of Bromley accepts.

Speaking to TN16 neighbours before submission avoids most of it. A Biggin Hill measured survey captures the roof structure as well as the plan.

Party wall procedure runs alongside the Biggin Hill application, not after it. Once consent is granted, building regulations drawings follows for the TN16 property.

Biggin Hill is characterised by 1930s semi-detached, concentrated across TN16 in the Biggin Hill / Downe area. A Biggin Hill scheme is designed around what the 1930s semi-detached can actually carry. On the Biggin Hill stock specifically: on these 1930s semis the prior approval route often replaces a full application, and the drawing set is smaller as a result. It is the first thing checked at the Biggin Hill survey. The prevailing Biggin Hill eaves line is the reference Bromley Council uses, which is why the proposed elevation is drawn with the neighbours on it.

Bromley Council assesses Biggin Hill basements on standard grounds. One visit to the Biggin Hill address covers loft conversion drawings for TN16 properties and house extension drawings too.
