Extension Builder in Gillingham

If you're expanding your home in Gillingham, you need an extension builder who understands the town's unique housing stock and the local planning landscape. Gillingham's mix of Victorian terraces in the town centre, sprawling 1960s semis across Rainham and Gillingham's residential fringe, and newer developments around the docklands means extension work here demands versatility. Whether you're adding a kitchen extension to a mid-terrace on Woodlands Road or planning a loft conversion on a post-war property, a local builder knows the Building Control requirements of Medway Council, the conservation sensitivities of older properties, and the practical challenges of working in a densely built area. The demand for quality extensions is strong — space is at a premium in north Kent, and extensions offer homeowners far better value than moving.

Running a Extension Builder Business in Gillingham

Gillingham's Victorian and Edwardian terraced housing stock creates steady demand for rear extensions and kitchen conversions. The town sits between the Medway waterfront and commuter-belt suburbs stretching towards Sittingbourne and Faversham. Many properties date from the 1920s–1950s, with older housing concentrated around the town centre. Modern estate homes in the surrounding villages offer younger families the chance to add value through thoughtful extensions. Local planners are typically receptive to residential extension applications, providing consistent work for experienced builders.

Frequently Asked Questions

How much does an extension cost in Gillingham?

Do I need planning permission for an extension in Gillingham?

Single-storey rear extensions and some side extensions may fall under permitted development, avoiding full planning permission. However, Gillingham's planning authority reviews each case individually. Building regulations approval is always required. Consult your local council before starting work.

How long does an extension take to build?

A single-storey rear extension typically takes 8–12 weeks from foundation to completion. Two-storey extensions take 12–18 weeks. Weather, building regulations inspections, and material delays can extend timescales. Your builder should provide a realistic schedule upfront.

Is my extension builder VAT registered?

Most established extension builders in Gillingham are VAT-registered if their annual turnover exceeds the threshold. Ask your builder for their VAT number before commissioning work. Confirm whether quoted prices include VAT or are net of VAT.
