Frequently Asked Questions
Do I need planning permission for a house extension in Coventry?
Many single-storey rear extensions fall under permitted development rights and don't require a planning application. Key limits include a maximum rear projection of 3m for terraced/semi-detached or 4m for detached homes (or up to 6m/8m under the Neighbour Consultation Scheme). Properties in conservation areas or those that have used up permitted development rights will need formal planning permission. A local builder in Coventry can advise.
How much does a house extension cost?
A single-storey rear extension in Coventry typically costs £1,500–£2,500 per m², so a 20m² extension might cost £30,000–£50,000 fully finished. Double-storey extensions cost more per m² due to additional structural requirements. Getting multiple quotes through Quote2 helps you understand the local market.
How long does a house extension take to build?
A standard single-storey extension takes around 12–16 weeks from breaking ground to completion. Planning (if required) adds several months to the programme. Double-storey or more complex projects take longer. Your builder will provide a detailed programme at the outset.
Do I need an architect for a house extension?
Not always — for straightforward extensions, an experienced builder can often handle design and building regulations drawings directly. For more complex projects or planning applications, an architect or architectural designer is worth the investment. Some builders on Quote2 work with architects or can recommend one in Coventry.
