Types of Loft Conversions we build


When the planning regulations for London were simplified for home owners, loft conversions increased in popularity.  Some homes no longer require permissions, making the process even easier.

We can help you plan the right loft conversion for your property, to give you the extra space you need.  Our expert teams offer the highest quality and professionalism to help you through the process as stress free as possible.

When planning a loft conversion there is a lot of things to consider and decide upon, like what type of conversion do you want.

What is a Dormer Loft Conversion?

First up is the most popular type, the Dormer loft conversion, which has a simple flat roof.  The loft doesn’t need any major changes and creates a box shape at the top of the house.

What is a Sky Light Loft Conversion?

A sky light loft conversion (also known as Velux loft conversion )require a lot less construction work than other forms of conversions. This type will reinforce the floors and walls of the interior of the attic/loft and add windows for to provide natural light into the newly created room – without any structural changes to the outside.

The bonus is as the structure of the roof is not altered and only windows are added you most likely will not need to get planning permission.

By using the Velux (or similar style) windows in the roof you’ll add in natural light and ventilation.

What is a Hip to Gable Loft Conversion?

Hip to gable types are Ideal for a semi-detached loft conversion or detached properties (or for an end terrace house) with a hipped roof, hip to gable loft conversions are a great way to add more space in to your property – whether it be for another bathroom, office or another use.

Typically, most hip-to-gable loft conversions do not require full planning permission – but always double check this at planning stage.

It is not usually necessary to get planning permission for a typical hip-to-gable loft conversion as this falls under ‘permitted developments’ allowed by homeowners.

What is a Mansard Loft Conversion?

A Mansard loft conversion is created by raising the shared wall – with a flat roof with one outer wall sloping slightly inwards.  These are typically found at the back of the house.    This type is most popular terraced house loft conversion

Windows are fitted into the new roof, similar to the dormer style, and the conversion is usually added to the rear of the property – but can be added to both rear or front (double mansard) – if permit allows.

This conversion the most of space, effectively adding another floor to your home and is becoming one of the most popular types – appealing to homeowners who want more space without the hassle of moving.

Loft Conversion Cost


How much does a loft conversion cost?  On average a loft conversion can cost between £30,000 and £50,000 (and up).  The cost of your loft conversion depends on a few factors including the existing space, structural requirements, type of conversion and the use of the completed space afterwards.

Space can be a precious commodity for London home owners, a home extension or loft conversion I one of the best ways to achieve that coveted extra space!

If you’re on a budget and looking for a basic loft conversion cost, than the sky light loft conversion (Velux loft conversion) could be for you.  With an average cost of around £30,000, this type converts your existing space with no external structural changes for the fastest and less disruptive option.

On the upper scale, a full double Mansard or Dormer loft conversion gives you your more space in the loft/attic – of course being a much larger scale project, requiring structural changes and a new roof will cost between £35,000-£50,000.

During planning, you’ll need to also have to factor in the loft conversion stairs cost to ensure the space is accessible safely.

Loft Conversion Uses


The options are endless when deciding what to use your new space for, this is best decided upon before you get a quote and work begins -so you can factor in the relevant facilities and outlets.

Most home owners use a loft conversion space for extra living/bedroom spaces.  Depending on the size and type of conversion you can potentially work in a 2 or 3 bedroom loft conversion – on average typically we see one or two bedrooms and a bathroom.

Other homeowners have created a new space for an office, a kids playroom, or for those with tech savvy teenagers – how about a gaming room?

Some homeowners have used the space as a walk in closet and more – perfect for a low ceiling loft conversion or a sky light loft conversion.
