Hip-to-gable loft conversion drawings in Kensington and Chelsea

Where a Kensington house might still qualify

Some houses sit outside every designation, and some Article 4 directions cover other matters than roofs. Each direction names what it withdraws, so we read the one that touches your address. Where Class B survives, the volume cap is 40 m³ (terrace house) / 50 m³ (any other house) additional roof volume, and Eaves-retention and 0.2 m set-back conditions do not apply to a hip-to-gable enlargement.

The front still counts: No enlargement beyond the plane of a roof slope that forms the principal elevation and fronts a highway. And the walls: No part of the enlargement may extend beyond the outside face of any external wall of the original house (except where joining a rear or side extension roof). A Lawful Development Certificate in Kensington and Chelsea then proves the position, and the more usual route is planning drawings in Kensington and Chelsea.

The cost of getting it wrong in this borough

Property values explain the care. A semi-detached house in the borough averages £3,051,816 and a detached one £4,525,386. A refused application or an unlawful roof can undo a great deal of value, so a measured survey and a clear route come before the design.

Only 17 per cent of households live in houses, so most of the stock is flats, and flats cannot use householder rights at all.

Householder decisions in the borough

The council decided 664 householder applications in its latest year, granting 93.7 per cent, with 91.9 per cent on time. The grant rate is high, though it reflects every type of householder scheme.

It is not a licence for any roof. It says nothing specific about gables.

Stair and fire safety on narrow plots

On a narrow plot the stair is the limiting factor. If the full height cannot be reached the rule is Loft conversions where 2.0 m cannot be achieved: 1.9 m at the centre of the stair, 1.8 m at the side (half width). And New storey above 4.5 m by loft conversion: protect the full escape route with fire-resisting doors (min E 20) and partitions (min REI 30).

Those requirements, together with the structure, are drawn up for the Building Regulations stage; see building regulations drawings in Kensington and Chelsea.

What a planning-grade set looks like here

Because most Kensington and Chelsea addresses fall inside a designation, we assume the application route from the start and draw to its standard. That includes a street elevation, a roof plan, existing and proposed floor plans and sections, plus a short design statement for the roof that explains how the new form relates to its neighbours.

Rear views matter as much as front views in a borough of closely built terraces and mews. A new gable flank is visible from gardens on both sides, and often from the upper windows of the houses behind. We draw the rear elevation with the neighbouring buildings in outline so the officer can judge visibility directly.

The survey underneath is the same as anywhere: eaves, ridge, hips, stacks and party walls on one datum. The difference is the level of documentation. A second chartered technologist checks the set before it leaves us, and you pay one fixed quote, VAT included, after the free constraints check. Council fees, if an application is needed, are paid to the council separately.

If an application is needed, we also prepare the roof plan and street elevation in a form the council can validate without queries, to keep validation queries to a minimum.
