The demand for house extensions and alterations has grown significantly in the last 18 months – people have used the Covid-era to reflect on their lifestyles and their home needs to enable them to live that lifestyle.  Whether it is an extra bedroom due to a growing family, a home-gym or additional accommodation to allow for working from home.  In addition, house purchases have soared and with that the opportunity for the new home-owners to alter their new home to suit their needs.

There are some key factors to consider when contemplating an extension:

What are you trying to achieve?

be clear in your mind what you want at the end of the project.


 Consider your “must haves” and “nice to haves”.


Both to yourself and your neighbours (there may be a Party Wall Award involved)

Return on investment

It may be worth talking to an estate agent or doing your own research about what your alteration /extension may add financially to your property.

The type of property you live in

 Listed buildings, for example, will have planning restrictions on them.

What have your neighbours been permitted?

This will give you a fair indication of what the planners may approve.

Is it allowed through permitted development?

See the Government link below for details on permitted development.
