A loft conversion adds space and value to your home.

An average loft conversion creates more than 70% of the equivalent floor space to the floor below it. This means an existing single-story house increases by approximately 40% in total footprint size. An existing two-story house increases by around 28-30% in overall footprint.


The additional space also adds significant value to your home, increasing an average of over 30%.

What is a loft conversion?

What is a loft or attic conversion really? Well, it’s all about making much better use of your existing roof space. You are probably only using your loft as storage for your Christmas decorations. Am I right? Well, why not convert that loft space into a stunning living space for you and your family.


Traditionally, a loft conversion would consist of making the existing space beneath your roof into a small room. Often used as storage space or a small home office, or perhaps a place to build your train set. Whatever it was used for, it was rarely done safely, was difficult to get in and out of, and probably didn’t comply with building regulations. This means it added no extra value to the sale price of your home.


A loft conversion today can mean something very different. A conversion can mean a truly amazing living space you’ll want to be in, with a custom-built staircase, lots of natural light, and plenty of extra floor space and head height. Your attic is now something to be proud of.

Type of loft conversions

You might have only one roof, but you have a lot of options:

Traditional – Convert within the existing roof space

Dormer – Place multiple or single extension to your existing roof space to increase usable floor space

Mansard – Very similar to a dormer, but more used on older style buildings.

Hip To Gable – This is where we convert an existing hipped roof, replace that section of the roof, and plus a gable end in creating space just like a dormer

Roof Lift – Where you need more space and your existing roof is not suitable for conversion we replace the entire roof structure

DIY or Partial – This could be any of the above, but where you want to complete part of the work. With this we complete the structural work and any additional tasks you do not want to tackle.

Questions and Answers

Whats included with a loft conversion by Milestone Homes

Do I need planning permission to convert my loft?

We offer a full range of loft conversions services, but a complete project includes everything needed through to being ready for decorating and laying finishing flooring, e.g. carpeting.

We also offer shell only projects. More information on that here.

Do I need to get get my loft conversion done to a set of regulations?

The vast majority of loft conversions do not require planning permission, as they fall under Permitted Development (PD) rights. This implies that your loft can be converted within the set rules without any additional planning requirements.

How long does it take to complete a loft conversion?

Simply put, yes. Without this sign-off, you will struggle to resell the home, and your house insurance may be null and void. These regulations are there to ensure the projects meet a minimum criteria on a number of key areas, including insulation levels, structural integrity, fire safety, and many more.

This will vary depending on how much structural elements need to be changed, the size of the loft, access, the type of conversion being done, and much more. However, a 10 to 12 week lapse time is what we aim for, from scaffolding being erected to the project being signed off.

Planning Permission and Building Regulation

What is the difference and what does it mean for your loft conversion?

It is generally assumed that a form of permission is required for building work or alterations of properties. However, it may not always be clear how the planning and building regulations approval regimes differ.


Building regulations set standards for the design and construction of buildings to ensure the safety and health of people in or about those buildings. They also include requirements to ensure that fuel and power are conserved and facilities are provided for people, including those with disabilities, to access and move around inside buildings.


Planning permission seeks to guide the way our towns, cities, and countryside develop. This includes the use of land and buildings, the appearance of buildings, landscaping considerations, highway access, and the impact that the development will have on the general environment.


For many types of building work, separate permission under both regimes (separate processes) will be required. For other building work, such as internal alterations, building regulations approval will probably be needed, but planning permission may not be.
