How much value does a loft conversion add?

Undergoing a loft conversion can increase your home’s value by as much as 20% but this can change according to your property type, the style of conversion you have and the amount of floor space you create.

This will depend on the style of loft conversion you choose and how invasive it is. Hip-to-gable and mansard conversions will almost always require planning permission, whereas dormer and roof light projects usually will not. However, if you want to extend the roof beyond a certain limit, make significant changes to the slant of the roof or add a balcony, you will definitely need planning permission.

Do I need a party wall agreement for a loft conversion?

Yes, you will need a party wall agreement for your loft conversion if you will be making changes to walls that are shared with another party, such as if you live in a terraced house.

How long does a loft conversion take?

As loft conversions are fairly major projects, they take around 7 weeks to complete. Expect to spend no less than 4 weeks on more straightforward renovations but as much as 10 weeks on more complex projects. such as a mansard conversion.

How disruptive is a loft conversion?

Loft conversions can be fairly invasive procedures, especially as they take a while to complete. The worst disruption will come during the early stages of the project when parts of your ceiling will need to be cut away to allow access. You will also need to anticipate having scaffolding on your house and people working inside your home. However, your construction team should be very professional and will do their best to minimise noise and disruption.

Can every house have a loft conversion?

Not every house will be able to have a loft conversion. Some loft spaces will not be large enough or may have too many load-bearing beams inside that would be hard to replace. Alternatively, your house might not have a suitable point where stairs can be installed to access the converted loft. There might also be barriers to your conversion if you live in a listed building, or cannot reach a wall party agreement with your neighbours.

Can you do a loft conversion in a new build?

In most cases, you will be able to convert the loft of your new build. However, the lofts of newer houses are built slightly differently from those of older properties so it may be a more complex project.

What is a dormer loft conversion?

Dormer loft conversions are a way of creating more headspace in your loft, where small extensions are created on a slanted roof. The extensions tend to have a box-like shape and often have windows, too.
