A rough guide on timescales for house extensions

All house extensions are different and open to various external variables such as the weather or the unreliability of people or machinery. Still, house extensions follow a rough timescale from assigning an architect to choosing your builder.

Design stage

When you’ve worked out your budget and what you want, you’ll need to contact some local architects in Coventry, Kenilworth, Leamington Spa and Warwick so that they can draw up the plans for your extension. If you possess the existing drawings for your home, these will speed up the process, and depending on availability, this stage takes around 2-4 weeks.

Planning

In any local authority across Coventry, Kenilworth, Leamington Spa and Warwick, planning will typically take around 8-10 weeks. If you already have a builder in mind for the construction, you can ask for their advice and the architect on how to speed up the process.

Party wall agreement

If you’re constructing on a shared property boundary or within 3 metres of one, you will need a party wall agreement. Your neighbours will have seven days to provide written consent, or they will be contesting the extension.

Hiring a builder

Once everything is in place, you can start to look for a builder. Ideally, you want to offer the tender to at least two, if not three, builders to get a spectrum of prices and quotes, and visiting previous house extensions they’ve completed is a sensible approach. Generally, the tender process takes around 2-4 weeks.

The build

The construction of your house extension will vary on several factors. Firstly, the size: is it a single or double-storey extension and secondly the location – is it side or rear of the property. A single-storey side extension will take around 6-8 weeks, whereas a double-storey rear extension with an abundance of glass could take between 12-16 weeks.
