Working with any proposed designs you might have, a structural engineer will put together the technical drawings your home will need to withstand the stresses of everyday use. These calculations can cover foundations, beams, rafters, lintel, concrete slabs, etc.
A structural engineer typically costs £950-2500.
It’s worthwhile getting a structural engineer in early so they can assess whether the supporting walls of your house will need extra support to carry the extra weight of the mezzanine. This will be vital information when it comes to building regulations.
While you might not necessarily require planning permission, obtaining building control approval will be a must.
In order to get the green light for construction, you’ll need to prove your mezzanine will be in compliance with UK building regulations. These regulations have been put in place by the government to ensure you create a safe and healthy environment for both your family and any affected neighbours.
For these types of projects, your main considerations will be…
- Fire safety
- Structural calculations
- Stairwell safety
- Plus showing proper guarding is in place to stop people (especially children) from falling.
You’ll also need to demonstrate party wall laws have been adhered to.
You may need a party wall agreement
If you live in a semi-detached or terraced house, you’ll need to see if your mezzanine will be attached to a shared wall. If so, then you’ll need to get a party wall surveyor on board.
This professional will first help put together a party wall notice. Once served, your neighbour will have 14 days to give written consent to the proposed works, otherwise, a long legal process will be triggered and you’ll need to get a party wall agreement in place. This can take up to two months to arrange.

Never underestimate the value of an architect
Lastly, it’s worthwhile considering an architect to help put your designs together.
We don’t just say this as an architecture practice, but because there’s a lot of fine details to consider that architects are experts in. Namely, they’ll be able to advise on whether or not you have sufficient head height, and how best to lay your mezzanine out to get the most space and to cause no damaging effects to floor below - such as obscuring any valuable light sources.
Don’t forget, any work you undertake with your home is an investment, one you want paying off when it comes to selling. An architect will make sure you get both the most space and style for your budget, making sure your money is tied to a project that will really pay off in the long run.
