Kitchen Extension FAQs

Are all kitchens suitable for extension?

Yes, almost all terraced, end of terrace, semi-detached, and detached properties are suitable for kitchen extensions. Victorian and Edwardian properties can be extended too, as long as the materials used match the original house.

How long do kitchen extensions take?

The average project takes 8-10 weeks, but if you have a larger extension or an unusual interior it may take longer. This duration is for the building work only, so if you need to apply for planning permission the process from beginning to end can take a lot longer.

Do I need planning permission for a kitchen extension?

Not always – you may be able to build your extension as a permitted development. Take a look at our Planning Permission page to find out more or give us a call.

Can you arrange for planning permission?

Avian Construction works with a number of architectural firms throughout London who will draw up the plans for your kitchen extension and can handle the planning application on your behalf, if you prefer.

Do I need a party wall agreement?

If the work involves an adjoining or boundary wall, it’s essential that you have a party wall agreement in place with your neighbours. Even if the work does not touch these walls, it’s best to let your neighbours know about the upcoming building work to maintain good relations. We can recommend a party wall surveyor if required.

Will the kitchen extension be inspected?

Yes – a building inspector will come to assess our work at regular intervals to ensure that it complies with building regulations. You are free to attend the inspections and ask questions.
