Loft conversion in Surbiton

Test the roof space before settling on a layout.

Start with the loft conversion brief

A measured roof survey should establish headroom, structural spans and where a staircase could meet the floor below. Plan the stair, escape route, insulation and building services together before treating the loft as another room.

Compare the proposed roof shape with the address-specific design guidance below. Record chimneys, shared walls and neighbouring rooflines, then ask the appointed designers to identify the structural work and consents the proposal needs.

The local building context

Thomas Pooley conceived Surbiton’s New Town, and building began in 1838 around the landscaped Claremont Crescent Gardens. The Claremont Road area keeps stuccoed Regency-style semi-detached villas and terraces, with original examples on the north side of Victoria Road and the east sides of Claremont Road and St Philip’s Road, while Claremont Gardens has red-brick houses of 1890. St Andrew’s Square, a later phase, has three-storey Gothic brick terraces of 1876 to 1884, and the Cadogan Road area runs from short terraces in Cleveland Road to large Italianate villas on Cadogan Road and Grove Road.

The Victoria Avenue area, farmland until the early 1890s, has cohesive groups of two-storey red-brick houses built between 1893 and 1904. Surbiton Hill Park was built from 1864 to 1887 as a middle-class estate, its earliest houses Italianate. Oakhill follows the old turnpike of Ewell Road, with stock-brick terraces and villas with stucco dressings, and since 2009 has included 15–25 Langley Road, large houses of three storeys and semi-basement moved out of Southborough. Christchurch, in Berrylands, has houses of the 1860s to the 1880s around the Grade II Christ Church.

A KT6 or KT5 postcode, or the name Surbiton on an address, does not tell you which council decides, whether a conservation boundary or listing applies, or which consent route to take. KT6 is also used in Tolworth, a Christ Church Road address in Berrylands is KT5, and Southborough runs west to the boundary with Elmbridge, a separate council with its own Long Ditton conservation area. Southborough’s boundary changed in 2009, so check the exact address on the council’s map, then the list entry, the Article 4 pages, the lease or title and the property’s planning history.

Local design and consent context

The council’s pages date the areas as follows: St Andrew’s Square, March 1971, extended October 1987 and June 1991; Southborough, January 1979, extended January 1989 and September 1991; Claremont Road, October 1987, extended July 1991; Surbiton Hill Park, January 1988; Oakhill, April 1988, extended September 2009; Victoria Avenue, July 1988, extended June 1991; Christchurch, September 1988; Cadogan Road, May 1989; Surbiton Town Centre, June 1991; Riverside South, February 2003; and Fishponds Park, November 2004. Southborough’s boundary also changed in 2009, when the Executive adopted the boundary its appraisal recommended and 15–25 Langley Road passed to Oakhill.

An Article 4 direction, as Kingston puts it, does not prevent development but requires planning permission to be sought for that type of work. The borough lists three. The Seething Wells Filter Beds direction, confirmed on 14 April 2021, protects the site’s biodiversity by removing the right to put up fences, gates and other enclosures on that site only. The commercial-to-residential direction, as modified by the Secretary of State on 14 June 2023, includes Surbiton District Centre and concerns turning commercial premises into homes. The third covers North Lodge and South Lodge.

Each Surbiton conservation area page, Southborough’s included, records no Article 4 direction. The 2009 Southborough appraisal listed Article 4(2) directions as a tool that could be applied where specific control is needed, but none has been made, so ask the council whether that has changed before planning work to the front of a house.

Access and site planning

Settle the street arrangements before a start date is fixed. Skips on the public highway are licensed only to skip companies; on private land no licence is needed, and a licensed skip has to be kept at least 15 metres from any junction, bend or road hazard. Only scaffold companies holding the public liability insurance the council requires can apply for a highway scaffold licence, and the scaffold must leave a 1.2-metre route for pedestrians. Hoardings need a licence even on private property, as do materials stored on the highway. Bay suspensions are charged by the day for each five-metre space, and the suspended spaces can lie up to 75 metres from the address; red routes are managed by TfL.
