Loft conversions in Nottingham

We design and build loft conversions for homes across Nottingham, where lace and hosiery money filled the inner suburbs with Victorian and Edwardian terraces and the council added estate after estate between the wars. That mix means no two lofts are quite the same. Whether it's a narrow terrace that needs a rear dormer or a semi with room for a hip to gable, we'll turn wasted roof space into a bedroom, office or bathroom that suits the house.

Converting lofts in Nottingham

Planning across the city is handled by Nottingham City Council, which lists 33 conservation areas, from the Lace Market and The Park to Sneinton, Mapperley Park and Clifton Village. In a conservation area, roof extensions such as dormers and hip-to-gable conversions aren't permitted development, so they usually need a planning application, and some properties, including on Waterloo Promenade and in Sneinton, also have Article 4 directions controlling smaller changes. When an application is needed, the council's householder design guide looks for dormers that line up with the windows below and aren't flat-roofed unless the case officer agrees. Flats don't have householder permitted development rights.

Outside those areas, many terraces and semis can be converted under permitted development, within the size and design limits. Either way, we handle the design, structural calculations and building control, so you have one team from first drawings to sign-off. We're about 7 miles from our base in Ilkeston.

How a loft conversion works

Our services

Loft conversion services in Nottingham

Every type of loft conversion, designed and built by one team, with structural calculations and building control handled for you.

  • Dormer loft conversions

    A box extension built out from the roof slope

    Built out from the slope of your roof, a dormer adds valuable headroom and floor space so the loft works as a proper room. We handle building regulations, structural engineering and every finishing touch.

  • Rear dormer extensions

    A full-width box across the rear roof slope

    A flat roof and vertical walls off the rear slope give maximum internal volume and a traditional room shape. Popular on terraced and semi-detached homes, with private building control, structural calculations and approvals all covered.

  • Mansard loft extensions

    A steep 72° rear wall with a flat roof above

    One of the most transformative options. The rear roof is rebuilt as a near-vertical wall, typically at 72 degrees, with a flat roof on top, creating room for several bedrooms or a large master suite.

  • Hip to gable conversions

    The sloping hip rebuilt as a vertical gable wall

    Made for semi-detached, end-of-terrace and some detached homes with a sloping “hipped” roof. We build the sloping side up into a vertical gable end, significantly increasing headroom and usable floor space.

  • L-shaped dormer conversions

    Two linked dormers forming an L in plan view

    Two dormers joined together, one on the main roof and one over the rear extension, forming an “L” from above. Ideal for Victorian and Edwardian terraces, using every inch of roof space.

  • Pitched dormers

    A small gabled roof over each dormer window

    A dormer with its own gabled roof that mirrors the main roof, keeping the character of period and traditional homes while bringing in extra space and plenty of natural light.

  • Velux conversions

    Roof windows set flush into the existing slope

    Roof windows fitted flush with the existing roofline fill the loft with daylight without major structural changes. They typically fall under permitted development, so they are quicker and easier to install.

  • Shell loft conversions

    Structure and weatherproofing done, fit-out left to you

    We build the weatherproof, structurally sound shell: steelwork, floor, roof alterations, dormer if required, windows, staircase and external roofing. You finish the interior at your own pace and budget.

Our process

How your loft conversion comes together

The same proven sequence on every project, from the first steel going in to the final sign-off, with you involved at the moments that matter.

  1. 01

    Steel fabrication & structure

    Work starts on day one with steel fabrication and the new structure, creating a strong framework to safely support your new living space.

  2. 02

    Stair fitting

    With the structure finished, we fit your new staircase so the loft is safe and easy to reach from the floor below.

  3. 03

    Last-minute design

    Once the stairs are in, you come up and see the space for yourself. Planning rooms and windows while standing in the loft is far easier than working from a drawing.

  4. 04

    Plumbing & electrics

    First-fix electrics and plumbing go in, and you can talk through ideas for your bathroom and main room with our electricians and plumbers.

  5. 05

    Insulation & boarding

    We insulate, plasterboard and build internal walls while our roofers and bricklayers work outside, keeping the time on site to a minimum.

  6. 06

    Completion & sign-off

    Plasterers, second-fix joiners, electricians and plumbers complete every detail on site, leaving you with a transformed home you’ll love for years to come.

    Mark and his team were brilliant from start to finish. They completed the shell loft conversion efficiently while keeping the quality of work to a very high standard. They explained every step clearly, gave helpful advice and recommendations, and dealt with any issues that came up without any hassle. We’ve been left with a fantastic loft conversion and me and my wife couldn’t be happier with the result. Thanks again!

    Mark and his team were incredible. It was unbelievable how quickly our cold dusty loft was transformed into a light and spacious luxury en-suite bedroom. Mark was always available to talk me through each stage of the conversion and help me make decisions when I had no idea what I wanted. I now have a beautiful bedroom and feel like I’m on holiday in my own house. Would highly recommend

    What can I say! Nothing but high praises for Mark and his team! We moved out and handed over the keys and came back to our vision becoming a reality! Mark and his team were 100% professional from pre-contract to completion. Not once did I feel that any question, call, concern or request was unanswered or ignored! An absolutely talented team and brilliant company who I’ve recommended and would continue to recommend over and over again! Thanks again Mark and your team!

FAQs

Loft conversions in Nottingham: your questions

Can’t see your question? Our team is always happy to talk it through.

Ask us a question

Do I need planning permission for a loft conversion in Nottingham?

Not always. Nottingham City Council decides planning applications in the city, and many loft conversions on houses fall under permitted development if they stay within the size and design limits. If your home is in one of the city's conservation areas, a dormer or hip to gable usually needs planning permission, and roof extensions to flats always need an application.

Which type of loft conversion suits homes in Nottingham?

It depends on the house. A terrace with a rear outrigger often suits an L-shaped dormer, and one without usually suits a straightforward rear dormer. A semi with a hipped roof often suits a hip to gable. In conservation areas, where planning permission is needed, a smaller pitched dormer or rooflights may be the better fit.

Do you cover Nottingham?

Yes. Nottingham city centre is about 7 miles from our base in Ilkeston, so the city is well within our area. We cover the whole of Nottingham, including suburbs such as Wollaton, and the surrounding towns, from Beeston and West Bridgford to Hucknall.

How long does a loft conversion take?

Most take between 6 and 12 weeks, depending on the size, complexity and type of conversion. Larger projects such as mansard or hip to gable conversions can take longer because of the extra structural work.

How much disruption should I expect during construction?

We keep disruption to a minimum. Most of the work is contained within the loft, and we keep the site clean and safe. In most cases you can carry on living at home during the build.

Do you offer free quotes?

Yes. Get in touch by phone, WhatsApp or the enquiry form and we’ll arrange a free quotation for your project.
