Structural alterations in Sevenoaks, from opening up rooms to extensions, renovations and landscaping

Building Work Across Sevenoaks and Its Villages

G Willard Construction is a builder based at Bodiam in East Sussex, about 24 miles from Sevenoaks in a straight line. We carry out structural alterations, extensions, conversions, renovations, new builds and landscaping for homes in and around the town, and we run each project from start to finish.

Sevenoaks grew from a medieval market town beside Knole into a commuter town after the railway arrived in the 1860s, and many later neighbourhoods were built on the grounds of old country estates. Its homes run from listed buildings near the High Street to Victorian villas, Arts and Crafts houses and 1930s semis.

Homes in Sevenoaks

The historic centre, within the High Street conservation area, has more than 100 listed buildings, many in Kent's traditional clay tile, tile hanging, ragstone, weatherboarding and red brick, with homes beyond the shops, particularly at the southern end and in Lime Tree Walk. Hartslands, built up from the 1840s as the first suburb outside the centre, is still dominated by small Victorian terraces. Once the railway reached Bat and Ball in 1862 and Tubs Hill in 1868, Italianate semi detached villas followed on Eardley Road and Granville Road, with large ragstone and red brick houses on Vine Court Road and Avenue Road, laid out in 1885.

In the 20th century the town grew as its estates were broken up. Wildernesse, sold in 1924, was laid out from the late 1920s with large Arts and Crafts houses by Baillie Scott and others, and Kippington Road, the old drive to Kippington House, is lined with large, individually designed houses. After Bradbourne Hall was demolished in 1937, semi detached and detached houses in brown brick, hung tiles and half timber filled the grid of roads around Lambarde Road, and the Montreal estate became Montreal Park, with detached houses from the 1950s. The town's first council houses went up at Greatness, on part of the old Greatness estate.

Rapid growth ended around 1960 with the Green Belt and landscape protection, and the council notes that Sevenoaks has few of the large 1960s and 1970s estates seen on the edges of many Kent towns, with most building since on infill plots or replacing older houses at higher densities. Riverhead, Dunton Green, Bessels Green and Chipstead form part of the Sevenoaks urban area, where Packhorse Road was built up with detached houses, mainly in the 1930s, on the grounds of Chipstead Place.

Structural Alterations in Sevenoaks

Many Sevenoaks homes date from before the Second World War, from the terraces of Hartslands to the 1930s semis around Lambarde Road. Where the rooms in an older house feel closed off, our structural alterations work opens them up: we take out load bearing walls, install steel beams designed by a structural engineer, form new openings and join rooms, such as a kitchen and dining room.

Removing a load bearing wall needs building control approval and a structural engineer's calculations, and we work closely with the engineer and building control throughout. Internal alterations do not normally need planning permission, but a listed building needs listed building consent for significant works inside or out. On the larger villas of Vine Court Road, generally on three floors with the top floor often in the roof, each new opening should be agreed with the structural engineer first.

Extensions and Loft Conversions Around Sevenoaks

Extensions range from single storey additions on Victorian and 1930s semis to two storey and wraparound extensions on the detached houses of Kippington, Montreal Park and the White Hart area. The council's Residential Character Area Assessment, adopted in 2012, gives design guidance for each character area, and the neighbourhood plan encourages applicants to show how their plans respond to it. The assessment notes that in the Victorian streets, intrusive extensions and dormers visible from the road have generally been kept to a minimum. For a loft conversion in these streets, rear dormers or roof lights are usually the better fit.

In the Green Belt, the council's policy allows proportionate extensions that keep the total floorspace, with earlier extensions and outbuildings within five metres, within 50 per cent above the original house, meaning the house as it stood on 1 July 1948 or as first built if later. Roof lights alone, with no added bulk, do not count towards this, but dormers do.

Driveways, Paving and Garden Landscaping

Our landscaping work covers paving, paths and patios, retaining walls, steps, drainage, garden levelling, turfing and planting, fencing, gates and outdoor seating areas, whether to finish an extension or as a project on its own.

Sevenoaks sits on the north slope of the Greensand Ridge, and around St John's the land falls away to the north, so gardens may need retaining walls, steps or levelling before paving goes down. The council's character assessment notes that parking pressure can affect front boundaries in several Victorian streets, so we plan driveways to keep as much of the wall or hedge as possible. For a house, paving over five square metres of a front garden in a surface that does not drain needs planning permission, unless the water runs to a lawn or border.

Planning, Conservation Areas and the Green Belt

Sevenoaks District Council decides planning applications, and Sevenoaks Town Council comments on those in the town as a statutory consultee. The development plan includes the Core Strategy of 2011, the Allocations and Development Management Plan of 2015 and the Sevenoaks Town Neighbourhood Plan, made in May 2023. A new Local Plan for 2027 to 2042 was published for comment in summer 2026, with examination expected in 2027.

Sevenoaks town has eight conservation areas of its own: Sevenoaks High Street, The Vine, Vine Court, Hartslands, Granville and Eardley Road, Kippington and Oakhill Road, Wildernesse and Brittains Farm, and nearby villages such as Riverhead, Chipstead and Seal have their own. Most of the built up area is outside the Kent Downs National Landscape, which takes in Knole Park and villages such as Otford, Shoreham and Ide Hill, while its boundary runs through Kemsing, Seal and Chipstead. The High Weald National Landscape lies further south. In a conservation area or a National Landscape, side extensions, rear extensions of more than one storey, roof enlargements and external cladding fall outside householder permitted development.

The Green Belt covers 93 per cent of the district and surrounds the town. Homes in it keep their permitted development rights unless these have been removed, and in villages washed over by it, the council's 2015 guidance says there may be room for limited infilling, normally one or two homes filling a narrow gap in a frontage that is already substantially built up. We recommend checking the position with the council early.

Common Questions from Sevenoaks Homeowners

Answers to common questions about building work in Sevenoaks.

Yes. We are based at Bodiam, about 24 miles from Sevenoaks in a straight line, and we work throughout the town, including Riverhead, Dunton Green and Chipstead, and in villages such as Otford, Kemsing, Seal, Sevenoaks Weald, Ide Hill and Brasted.

Sevenoaks District Council is the local planning authority. Sevenoaks Town Council comments on applications in the town as a statutory consultee, but the decision rests with the district council, which also applies the Sevenoaks Town Neighbourhood Plan.

Yes, within limits. Green Belt homes keep their permitted development rights unless these have been removed. Where planning permission is needed, the council expects an extension to be proportionate and, with any earlier extensions, to add no more than 50 per cent to the original floorspace.

Most of the built up area is outside it, but the Kent Downs National Landscape takes in Knole Park and villages such as Otford, Shoreham and Ide Hill. Homes inside it have fewer permitted development rights, so side extensions, rear extensions of more than one storey and roof enlargements need planning permission.

Yes. We take out load bearing walls and install steel beams to a structural engineer's design, with building control approval, to open up kitchens, dining rooms and living areas. Internal changes do not normally need planning permission, but in a listed home, significant works inside or out need listed building consent first.

It may be. Sevenoaks town has eight of its own: Sevenoaks High Street, The Vine, Vine Court, Hartslands, Granville and Eardley Road, Kippington and Oakhill Road, Wildernesse and Brittains Farm. Sevenoaks District Council publishes an appraisal and boundary map for each.
