How much does a loft conversion cost? Loft conversions are popular right now. And this is a great way to increase your living space without a lot of work.

But, how much does a loft conversion cost? I’ve seen loft conversions costing thousands, with the bare minimum often being around £1,000. There’s no doubt that a loft conversion is a good investment. For the cost, you get a whole new home.

Cost of loft conversions

Before starting to search for a loft conversion, ask for estimates from contractors or installers.

This will help to see if it’s realistic to build out your loft space, or to remove existing walls to provide additional space for storage or a room to sleep in.

It’s a piece of wall which forms part of the existing structure of the house, but protrudes through the roof.

When a cavity wall is built, it is called an attic extension.

Other costs involved

There are other costs to think about. You’ll need to be prepared to do a lot of the work yourself if you decide to move up a few floors in the house you live in. It’s a bit of a shock if you’ve only just moved in and you realise that there’s a lot of work to do.

Then you need to be prepared to make some changes to your home. Most new homes have to comply with various building regulations, such as obtaining planning permission, paying a stamp duty charge, and planning permission fee.

How does planning permission work? You may need to get planning permission for a loft conversion from your local council. You can’t just go straight to an architect, as you’d expect.

You need to do lots of research, and consult with a planning officer. A professional contractor can advise you further about acquiring these permissions.

Types of loft conversions

And you have to remember that you will need to have a loft conversion completed – unless you’re going to convert your loft into a loft house (where you do nothing!).

Most loft conversions are either full or half-lofts.

Half-lofts are usually semi-detached or detached. A detached half-loft, for example, will have a ground floor entrance and a basement with space for a kitchen, dining room and bathroom.

Semi-detached lofts are semi-detached homes with two floors.

Half-lofts cost more than full lofts, and you’ll find that these will have a kitchen and bathroom on the ground floor. A half-loft also has a living room or kitchen on the first floor, and then


It’s understandable that some people will be hesitant to invest their hard-earned cash into loft conversions. This is understandable, as you don’t know what you’re letting yourself in for. But the money is well worth it, as this will give you a beautifully converted loft, without the need for a shed or a loft conversion company.
