Hampstead Chartered Surveyors & Building ConsultancyEarl's Court houses sit on narrow plots with small yards or back gardens, so an extension here is planned around a tight rear building line.
Earl's Court is a place where the Article 4 map matters more than any permitted-development shortcut. RBKC directions withdraw the right to make small external changes — windows, front doors, boundary walls and roof coverings — on streets that include Earls Court Square, Eardley Crescent, Nevern Square and Philbeach Gardens. The council has also adopted conservation-area appraisals for Earl's Court Square, Earl's Court Village, Nevern Square and Philbeach, and an extension is judged against whichever appraisal covers the address.
The setting is monumental. Built around its great garden squares, Earl's Court sets sweeping stuccoed Italianate terraces along Nevern Square and Philbeach Gardens, while Penywern Road and Earl's Court Square carry tall white-fronted houses, most now flats. With one of the highest concentrations of period conversions in the borough, many projects combine reconfiguration inside a leasehold envelope with careful repair of stucco and joinery outside.
Cost reflects that constraint rather than plan area alone. An Earl's Court rear extension or side return is priced before VAT, and we size the scheme once the consent route is clear.
Extending a house in Earl's Court's dense terraces
Most Earl's Court Square houses have small rear gardens or yards that separate the different house types, and the Nevern Square terraces are built on narrow plots with small back gardens.
In Earl's Court Village the appraisal treats even high-level gaps as important in so dense a townscape, such as those above garages or over single-storey rear additions, so a second storey over an existing addition is weighed against the view it closes.
The largest green space there, Providence Patch, is a private communal garden behind Kenway Road, Wallgrave Road and Redfield Lane; houses that back onto it are extended with that shared garden in mind.
Policy CD13 is the borough's measure: no extension beyond the general rear building line of neighbouring extensions, and no higher than their general height.
A rear extension is Category 2 under the Construction Code, which still means a checklist and site construction management plan approved before work begins.
Nevern Square's terraces back onto small yards and gardens, and in Earl's Court Square the gardens to the rear give each group of houses its separation, so the space left behind an extension matters as much as the room it adds.
Not every Earl's Court terrace has the paired closet wings an extension usually works around. On Nevern Road the appraisal records no closet wings at all, so the backs are flat; numbers 2 to 24 Nevern Place have flat backs too, with shallow stuccoed canted bays at ground floor that the council calls unusual and attractive; and some houses in Nevern Place and Trebovir Road have single or very small closet wings.
Not in Earl's Court, but the same kind of work: Holland Avenue, Wimbledon, where we completed a rear extension.
On a street with flat backs we draw the neighbouring rears on either side, so the new extension reads as part of the terrace.
We map the neighbouring extensions on the survey before drawing anything, because the rear building line in Earl's Court varies from terrace to terrace.

House Extensions in Earl's Court: Questions
Has RBKC removed permitted-development rights on Earl's Court streets?
On many of them, yes. RBKC Article 4 directions take away permitted-development rights for small external changes — windows, front doors, boundary walls and roof coverings — on Earl's Court streets that include Earls Court Square, Eardley Crescent, Nevern Square and Philbeach Gardens. At those addresses, work permitted elsewhere requires a planning application.
Which conservation-area appraisals apply in Earl's Court?
Several adopted appraisals cover the area: Earl's Court Square (6 June 2016), Earl's Court Village (16 February 2017), Nevern Square (4 October 2018) and Philbeach (4 October 2018). Earl's Court lies within these conservation areas across its grand stuccoed garden squares, and the relevant appraisal frames how an extension is assessed.
What does a house extension cost in Earl's Court?
An Earl's Court rear extension, a side return and a wraparound are each priced before VAT after a survey and design. Since so much of the area is stuccoed and long divided into flats, consent and coordination weigh on the figure as heavily as the build.
What is the housing like in Earl's Court?
The area is laid out around great garden squares. Sweeping stuccoed Italianate terraces define Nevern Square and Philbeach Gardens; Penywern Road and Earl's Court Square add tall white-fronted houses, most long since divided into flats; and the district holds one of the borough's highest concentrations of period conversions.
Does the stucco frontage limit what I can do to an Earl's Court house?
It shapes it firmly. The typical Earl's Court stock is stucco Italianate terraces, garden-square houses and mansion flats, and the RBKC Article 4 controls reach roof coverings, windows and boundary walls on named streets. So even modest external work on a frontage is designed to keep the authentic stucco and joinery of the run intact.
