Bespoke Projects

Bespoke Loft Conversions

Some properties and briefs call for more than a standardised loft design. Nuloft specialises in larger, technically demanding and design-led conversions where structural requirements, architecture and the intended use of the space require careful coordination.

Built for Complex Projects

Complex roof structures, unusual property configurations and substantial alterations can require input from several specialists. We coordinate the structural, architectural and construction requirements so the different elements work together as one project.

Our experience includes large dormers, mansards, hip-to-gable alterations and bespoke combinations of conversion types. We can also manage projects involving restricted access, challenging roof layouts and complex relationships with the existing property.

Bespoke Design and Architecture

We work with best-in-class architects and specialist consultants where required to develop layouts around the individual property and client brief.

Custom staircases, larger areas of glazing, roof terraces, architectural features and high-specification interiors can be considered where suitable and included within the agreed project scope. The aim is to create a distinctive new space that feels integrated with the wider home.

Loft Conversion Types

Types of Loft Conversions

The most appropriate conversion depends on the existing roof, property and amount of space required. Nuloft delivers substantial conversion types suited to ambitious projects.

Dormer Loft Conversions

A dormer loft conversion can increase usable headroom and floor space by extending part of the existing roof. Dormers can be designed around a wide range of London properties, including larger layouts and more bespoke architectural designs.

Mansard Loft Conversions

A mansard loft conversion substantially alters the roof form and can create generous additional space. It can be particularly relevant to suitable London terraces and period properties, including high-specification and architect-led projects.

Hip-to-Gable Loft Conversions

A hip-to-gable loft conversion extends a suitable hipped roof to increase its internal volume. It is commonly considered for semi-detached and detached homes and may be combined with a rear dormer for a larger conversion.

Bespoke and Combined Loft Conversions

More complex properties may benefit from combining conversion styles or developing a bespoke structural and architectural solution.

This was my first every building project so a very daunting experience however Guy and his team were amazing. They were not only supportive and reassuring, but they were flexible with the change and development of my loft conversion project as it evolved. I had several companies quote for the job, but it was Guy’s honest and realistic approach to the plan of work and budget that made my decision to use them which paid off because my daughter now has her dream room. The team that completed the physical build were nothing short of amazing lead by the most wonderful man Kosta who took such pride in the work and was ridiculously accommodating. Having a bunch of strangers in your home for 6x weeks could have been very disruptive especially with young kids at home however they were respectful, friendly and other than a few particularly dusty days it was very non-intrusive. The work was finished to a high standard and completed in record time. I was shocked at how quick and efficient the whole build was. It has completely changed the dynamics of our home and we could not be more grateful to Guy, Kosta and the team for making this happen.

5 stars Nuloft renovated our house about three years ago, including a rear extension and loft conversion, and we’re still really happy with the result. They were easy to work with, good at keeping in touch, and stuck to the budget and timelines, which made a big project feel much more manageable. Like with any renovation, there were a few hiccups along the way, but they were always quick to sort things out and put things right. Even now, three years later, they’re still really helpful whenever we need advice or have a question about the house. We love our home and would definitely recommend them to anyone thinking about doing a similar project

Recently had a loft conversion done by Nuloft and was pleasantly surprised at how smoothly it went. Having heard some horror stories about conversions from other companies, I was a little worried about the whole process. However the team were excellent, finished bang on schedule (which was nice) and the results were exactly as planned and costed. Not even a penny over budget. It's nice to come across some old fashioned customer care when most companies just want to grab the money and run.

We worked with Steve and Tani from Nuloft on the full renovation of our Victorian house. From our initial meeting up to project completion they were a dream to work with - professional, courteous, proactive, punctual and with excellent communication and attention to detail throughout. The project was finished on time and within budget and we couldn't be happier with the result. Highly recommend.

We met with 5 different companies before we decided on nuloft and couldn't be happier with our decision! They were extremely professional throughout and provided great advice on how to make most use of the space. We're so grateful and love the end result.

Nuloft completed a beautiful loft conversion on our property in Sidcup. They were really personable and courteous and it was far less stressful than we anticipated. Roy - Sidcup
