Why convert your loft

Loft Conversions For All Houses

With house prices continuing to rise and the cost of moving home often running into thousands of pounds, it is no wonder that more people are choosing to improve and extend the home they already have.

If you don’t have the land around your home for a traditional extension, a loft conversion is well worth considering. Conversions make use of the structure that already exists above your home and, in most cases, this means less building work, so a conversion is often cheaper than an extension. If you need more space than the existing roof allows, our in-house design and construction team also builds loft extensions.

Loft Conversion Specialists

Here at Unique Lofts, we understand there are many different reasons for wanting a conversion, from an extra bedroom to a dedicated office. During the survey and quotation process, we discuss your needs and requirements so that you are left with your ideal space.

We work across a wide range of areas, from Barnet and Enfield to St Albans. Speak to our friendly team by filling in our quick contact form or call us on 020 8088 0329.

A Wide Variety of Loft Conversion Options

There are many different styles of conversion to choose from, and the right one for you depends on the floor space in your loft, the shape of your roof and how you want to use the room. Here is a summary of the loft conversions we build. Tap any type to jump straight to it.

Rear dormer

Hip-to-gable

Rooflight (Velux)

L-shaped

Mansard

01 / Rear dormer

Rear Dormer Loft Conversions

Dormer loft conversions are one of the most popular choices because they add so much usable space. A rear dormer extends the rear roof slope outwards, creating extra headroom and a more generous floor area, which makes the room far more practical. Dormer lofts are a particularly good option for bedrooms, and there is often room for an ensuite too.

One of our recent rear dormers runs across the full width of the rear roof, finished in grey horizontal cladding with dark window frames and three groups of windows, giving the bedroom inside plenty of natural light.

02 / Hip-to-gable

Hip-to-Gable Loft Conversions

In a semi-detached or detached house with a hipped roof, a hip-to-gable (or gable-end) conversion can create a large bedroom suite or even two bedrooms, making it a great option for a growing family. The sloping side of the roof is built up into a vertical gable wall, so the loft gains a lot more usable space.

Hip-to-gable conversions are often combined with a rear dormer. On one recent project, the extended roofline has two rooflights in the front slope and a tile-clad dormer to the rear, with the finish matched to the existing roof.

Good to know

Mark and his team completed our hip to gable loft conversion in September. The pricing was good and they came in on budget. The extra space is fantastic and we are delighted with the outcome.

03 / Rooflight (Velux)

Rooflight (Velux) Loft Conversions

Velux or rooflight conversions are typically the simplest type of loft conversion. Rather than changing the shape of the roof, we install rooflights to open the space up and let the light in. There are several types of Velux window to choose from, and some even open out to form a small balcony.

Rooflights work best where there is already enough headroom. On recent projects we have fitted windows into both roof slopes for light from either side, and a full-length rooflight that opens into a balcony with side railings.

04 / L-shaped

L-Shaped Loft Conversions

An L-shaped conversion combines a rear dormer on the main roof with a second dormer over an existing rear extension, joining the two to form an L. Where the roof layout allows, this can make room for extra bedrooms, a bathroom or a dressing area.

Two of our recent L-shaped conversions have glazed Juliet balconies that fill the bedrooms with daylight. One is clad in natural slate and the other in clay tiles, each chosen to suit the brickwork of the house.

Good to know

We used Mark and Unique Lofts for an L-shaped dormer. The team were facilitative of a two-stage planning process to maximise the amount of space we could add. The team were great on-site, and build quality was high.

05 / Mansard

Mansard Loft Conversions

Mansard conversions are much larger and can add space to the front and rear of your property. They are a great option for mid-terrace houses, as they can add almost an entire floor. A mansard needs more construction, because the roof is rebuilt with a steep, almost vertical face and a much flatter top, giving you a far bigger space to live in.

A recent mansard of ours is clad in slate with traditional lead flashing around the projecting windows, so it sits comfortably with the rest of the street.

Loft extensions

Loft Extension or Loft Conversion?

You will hear both terms, and people often use them for the same thing. Strictly speaking, a loft conversion uses the space inside your existing roof, while a loft extension changes the shape of the roof to add headroom and floor area. We design and build both, so whichever you call it, our in-house architect and structural engineer will help you choose the right option for your home.

Need more room on the ground floor instead? Take a look at our house extensions.

Loft conversion

Uses the space inside your existing roof. A rooflight (Velux) conversion keeps the roof shape as it is and adds windows, so it works best where there is already enough headroom.

Loft extension

Changes the shape of the roof to add volume, with a rear dormer, hip-to-gable, L-shaped or mansard extension. This creates more headroom and floor area, so you can fit in bigger rooms, a staircase that meets building regulations and often a bathroom. An L-shaped design can also take the new space over an existing rear extension.

Inside your loft

Bedrooms, Ensuites & Storage Built Around You

A loft conversion is more than a new roof. Our onsite team finishes the rooms inside too, so the space works for the way you live.

Bespoke wardrobes & storage

Built-in wardrobes and drawers are designed and built on site by our project team, made to measure to fit under the slope of the roof. They can turn the front of the loft into a dressing area for a main bedroom suite.

Ensuites & bathrooms

Many of our conversions include a new ensuite or family bathroom. From compact shower rooms to a freestanding bath with a walk-in shower, we plan the layout to make the most of the space.

Skylights & natural light

A well-placed skylight over a landing, stairwell or bathroom brings daylight into the darkest parts of a loft and makes the whole floor feel bigger.

 Trustindex verifies that the original source of the review is Google. We recently had our loft conversion completed by Unique lofts Ltd. We couldn’t be happier with the experience we had from start to finish.
From day one, Ben and his team set the tone; punctual, professional, and genuinely respectful to our home. The site was kept clean and tidy throughout, which made a huge difference to daily life, during the conversion. They were organised, communicated well, and delivered the project on time in just six weeks.
The quality of work was always of a high standard. The care and professionalism of the team really stood out during and after the conversion. We could see that they took real pride in their work.
We would highly recommend Unique lofts and the team to anyone considering a loft conversion.

 Trustindex verifies that the original source of the review is Google. Engaged Mark and his team on our loft conversion. Mark handled all the paper processes and Ben (together with Martin)  was the onsite manager organising all the deliveries and timings of other contractors. They were a pleasure to have working on site. Tidying each evening and very careful as were the tradesmen on the team. All in all a credit to the industry.

The team were facilitative of a two-stage planning process to maximise the amount of space we could add. The team were great on-site, and build quality was high. They suggested alternative approaches to e.g. skylights and windows to save money. We'd use UL again for future extensions.

 Trustindex verifies that the original source of the review is Google. We recently had a loft conversion with Unique Lofts and I would highly recommend. Very professional and courteous team, communication was great, on time and work completed on schedule even with additional work being carried out. We’re very happy with the end result, rooms more spacious than we expected (head height in particular) and all completed to a very high standard. The project did come in above our budget, but this is due to additional work we requested and some unforeseen work, all of which was explained fully by the team and options were provided before agreeing on the best way forward. Overall we’re very satisfied and I would highly recommend.

 Trustindex verifies that the original source of the review is Google. Had a very positive experience with Mark and the Unique Lofts team for our loft conversion. I would highly recommend them.

Michael and Brad (our team) were friendly, dedicated and hardworking. Our neighbours, who had the skip chute cross their garden, also shared how considerate and friendly they were.

Michael kept me in the loop, followed up on my enquiries and gave some really helpful advice in moving airing cupboards and opening up the loft space for more natural light.

All in all, highly recommended.

 Trustindex verifies that the original source of the review is Google. I would highly recommend Unique Lofts and was lucky to find them after another firm let us down. Our team were Ben, Martin and Connor who have been considerate, incredibly skilled and hard working. Even our neighbours commented on what nice guys they were. Ben was our main contact and kept me updated, followed up on my enquiries and turned up when they said they would. Every trades person Unique used turned up on time, cleaned up after themselves, were professional and very good at their jobs. Unique invoiced exactly as quoted and were a pleasure to work with. Thank you Unique Lofts!

Questions

Loft conversion FAQs

Can’t see your question here? Call us on 020 8088 0329 or send us a message on WhatsApp.

Which type of loft conversion is right for my house?

It depends on your roof shape, the headroom you have now and how you want to use the space. Rear dormers suit many houses, hip-to-gable conversions suit semi-detached and detached homes with hipped roofs, and mansards suit many terraces. We will look at your roof and talk you through the options.

What is the difference between a loft extension and a loft conversion?

A loft conversion uses the space inside your existing roof, often with rooflights. A loft extension changes the shape of the roof, with a dormer, hip-to-gable, L-shaped or mansard extension, to add headroom and floor area. We build both.

Can you extend over my existing rear extension?

Often, yes. An L-shaped loft conversion joins a dormer on the main roof with a second dormer over a rear extension, where the roof layout allows.

Do I need planning permission for a loft conversion?

Many rooflight, rear dormer and hip-to-gable conversions can go ahead under permitted development. Mansards usually need planning permission, and so can any conversion in a conservation area or where permitted development rights have been removed. We check this for your home and make any application to the council on your behalf.

Is my loft suitable for a conversion?

Headroom is the first thing we check, along with the roof structure and where the new staircase can go. If the headroom is tight, a dormer, hip-to-gable or mansard can create the height you need. We will assess this when we visit.

How long does a loft conversion take?

Every project is different, so we agree the programme with you before work starts. As an example, one recent loft conversion was finished on time in six weeks.

Do you handle building regulations?

Yes. We manage building regulations throughout the project, and when the work is finished we put together all the paperwork and send it to you for your records.

Can you add an ensuite or bathroom?

Yes. Many of our loft conversions include an ensuite or family bathroom, from compact shower rooms to larger bathrooms with a freestanding bath.

Do you build wardrobes and storage?

Yes. Our onsite team designs and builds bespoke wardrobes and drawers made to measure to fit under the roof slope.

How much does a loft conversion cost?

The type, size, structure and finish all affect the cost, so every quote is based on your home. Get in touch and we will arrange your free quote.
