We work in five Nottinghamshire council areas, all covered from our base in Ilkeston. Each has its own conservation areas and design guidance, so here’s what to expect where you live.
Planning for a loft conversion is decided by your borough or district council, not by Nottinghamshire County Council. Outside conservation areas, the rules are national: many dormers and hip to gable conversions count as permitted development, as long as they stay within the size limits, use similar materials and don’t face the road.
Where councils differ is in the detail. Each has its own conservation areas, where roof extensions need planning permission, and some publish design guidance that shapes what they’ll approve when an application is needed. We design with your council’s guidance in mind from the start, and take care of the structural calculations and building control.
Nottingham
Nottingham City Council
Nottingham
Wollaton
The city has 33 conservation areas, from the Lace Market and The Park to Sneinton, Mapperley Park and Clifton Village, and three of them are in Wollaton: Wollaton Village, Wollaton Park and Sutton Passeys. In any of them, a dormer or hip to gable needs planning permission, and some streets, including Waterloo Promenade and parts of Sneinton, also have Article 4 directions that bring smaller changes under control.
Where an application is needed, the city’s householder design guide looks for dormers set back from the front wall and lined up with the windows below, and isn’t keen on flat roofs unless the case officer agrees. Victorian and Edwardian terraces with a rear outrigger usually suit an L-shaped dormer. In Sutton Passeys, many bungalows are metal-framed ‘Crane houses’, so a structural survey comes before any design work.
Beeston has two conservation areas: West End, around the parish church and Manor House, and St John’s Grove, the tree-lined avenues laid out from 1878. Stapleford has two more, Church Street and Nottingham Road, where several framework knitters’ houses are listed and need listed building consent as well as planning permission. Broxtowe’s three Article 4 directions are in Cossall, Kimberley and Strelley, so they don’t affect either town.
Outside those areas, many conversions go ahead as permitted development. Beeston’s 1930s semis with hipped roofs often suit a hip to gable with a rear dormer, while the older terraces in both towns usually take a rear dormer. Later estate houses tend to have trussed roofs that need more structural work, and Stapleford’s steep-roofed chalet bungalows may have space for roof windows or small dormers.
West Bridgford has no conservation area of its own, so for many houses a rear dormer or hip to gable can be built as permitted development. East Bridgford is different: most of the village has been a conservation area since 1973, with 20 listed buildings or structures including St Peter’s Church, so roof extensions there usually need planning permission.
When an application is needed anywhere in the borough, Rushcliffe’s Design Code, adopted in 2025, normally expects dormers to be set in at least 500mm from the eaves, ridge and party walls, won’t accept side dormers, and notes that some shallow-pitched roofs may not be suitable for converting at all. In practice, the extra space is usually planned at the back of the house.
Ashfield’s residential extensions guide is one of the clearest in the county on dormers. It asks for dormers kept as small as possible and related to the windows below, says a dormer should never look like a large flat-roofed box, and treats traditional pitched-roof dormers more favourably. Front dormers are unlikely to be accepted unless they’re already a feature of the street.
Hucknall Town Centre became a conservation area in 2019, and Sutton in Ashfield Church and Market Place in 2015; homes in either need planning permission for a dormer or hip to gable. Semi-detached houses are the most common homes in Hucknall, and a hip to gable with a rear dormer often suits the hipped ones. On newer estates, it’s worth checking whether permitted development rights were removed when the estate was approved.
Mansfield has seven conservation areas: Market Place, Bridge Street, West Gate, Nottingham Road, Terrace Road, The Park and Crow Hill Drive. The Park and Crow Hill Drive are mostly homes, with slate or plain clay tile roofs, where a smaller pitched dormer or roof windows usually suit best. None of the seven reaches West Mansfield, where nearly half of homes are semi-detached and many can be converted as permitted development.
In Mansfield Woodhouse, the conservation area designated in 1972 covers the medieval core along High Street and Station Street, with its stone walls and pantile roofs. Rooflights in the existing slope are often the simpler route there. The early 20th-century stone terraces on streets like Parkers Lane and Charles Street usually suit a rear dormer finished to sit well with their slate roofs.
Our base is in Ilkeston, on the Derbyshire side of the county line. From there we cover Nottinghamshire from Stapleford and the centre of Nottingham out to Mansfield and East Bridgford.

Planning a loft conversion in Nottinghamshire?
We’ll check which rules apply to your home before we design anything, and give you a free quote.
We cover the towns listed on this page and the areas around them. If you’re somewhere else in Nottinghamshire, get in touch and we’ll let you know whether we can help.
How do I find out if my home is in a conservation area?
Each council publishes maps of its conservation areas, and the links on this page go to them. We check as part of our survey, along with whether your home is listed or covered by an Article 4 direction.
What is an Article 4 direction?
It’s a council order that removes some permitted development rights in a particular area, so work that would normally go ahead without planning permission needs an application. In Nottingham, for example, some properties on Waterloo Promenade and in Sneinton are covered by one.
Can you help if my conversion needs planning permission?
Yes. We manage the whole project, including any planning permission. We prepare the drawings and design the conversion to suit your council’s guidance from the start.
