Common Questions
Frequently Asked Questions
Get answers to common questions about our high-end extensions services in Kent
1How much does an extension cost in Kent?
Extension costs in Kent typically range from £1,500-£2,500 per square metre, depending on the specification and complexity. A single-storey extension of 20 square metres would typically cost £30,000-£50,000, whilst a two-storey extension could range from £60,000-£100,000+. We provide detailed, transparent quotes tailored to your specific project requirements.
2Do I need planning permission for an extension in Kent?
Many extensions can be built under Permitted Development Rights without planning permission, provided they meet specific size and height criteria. Generally, single-storey rear extensions up to 6 metres (8 metres for detached houses) and within 4 metres of height may not need permission. However, local regulations and conservation areas have different rules. We recommend a pre-application consultation, which we can arrange.
3How long does it take to build an extension?
A typical single-storey extension takes 3-4 months from start to finish, whilst a two-storey extension usually takes 4-6 months. The timeline includes groundworks, structural work, first fix, second fix, and finishing. Factors affecting duration include size, complexity, weather, and material availability. We provide a detailed project timeline during the quotation stage.
4Will I need to move out during the extension work?
Most clients remain in their homes during extension work. We maintain clean separation between the construction area and your living space, using dust barriers and temporary external access where possible. For larger projects involving significant structural work or when the existing kitchen/bathroom is affected, you may need alternative arrangements for short periods. We discuss this during planning.
5What's included in your extension service?
Our extension service covers everything: initial design consultation, structural calculations, planning application assistance (if required), building regulations compliance, groundworks, brickwork, roofing, carpentry, plastering, electrics, plumbing, and final finishes. We project manage the entire process and coordinate all specialist trades to ensure a seamless build.
