Loft Conversion Enfield

Our team will first sit down with you to discuss your requirements in detail, gaining an understanding of what you need the space for. We will also carry out a survey of your loft space at this time, which enables us to advise you as to what type of conversion would be best suited.

You can trust that our team will take care of everything from start to finish. If your conversion requires planning permission, we can apply for it on your behalf. We can also handle the architectural planning and structural calculations, continuing into the build phase and final sign off. We are a London loft conversion company that can do it all.

As your loft conversion company in London, we can generally complete the conversion within 6-7 weeks if we don’t require planning permission first.


Many homeowners find themselves running out of liveable space, but simply don’t have the outside space to undergo home extensions as their home improvement option. Rather than spending a large amount of money moving to a larger property, you can invest in your current home by converting the loft space. Most property owners don’t utilise their loft space to its full potential, and that is where we come in to help.

There are many benefits to investing in a loft conversion from our London loft conversion company. For starters, it is a great way to invest in your property; while the original cost of the conversion can be between £30,000 to £40,000, it will actually increase the value of your home. Should you choose to move in the future, your loft conversion will have paid for itself.

Additionally, you gain lots of extra living space, all without sacrificing any needed space as you do with extensions. Since your loft is largely unused, you are simply maximising its potential by having it converted. This can then create spaces such as extra bedrooms, a family bathroom, a playroom for the kids, or even a home office.

Better yet, in most cases, you won’t need planning permission to convert your loft, so you can have the project completed much quicker than you would an extension.


Here at Firtree Building Services, we will be able to advise you as to which type of loft conversion would best suit your property. There are a few different types available, and which one works best depends on factors such as the type of roof you have, what you wish to use the space for, and your budget.

The three types of loft conversion we offer include:

  • Internal Loft Conversions
  • Dormer Loft Conversions
  • Roof Off Loft Conversions


These are the simplest option and the cheapest as far as budgets go as they require very little work to be carried out. Your existing loft space will require minimal alternations along with some small additions, such as roof windows and insulation to stronger flooring.


This loft conversion involves adding dormer windows to the loft space, which will increase the height of the room. Dormer windows are usually added to the back of the property but, if you have the needed planning permission, they can also be added to the front or side too.

We can build single, full-width, side, and L-shape dormer conversions as well as hip to gable conversions, all depending on which would best suit your property.


This type of loft conversion will require that we take the roof off your property and replace it with a brand new structure. If head room is lacking in your loft space, this will be the best type of conversion for you as the new roof structure will create additional headroom and more space.
