Few terraces, plenty of villas, a lot of flats
Bournemouth doesn't look like most English towns from the loft hatch. At the 2021 Census only about one household in ten across BCP lived in a terraced house. Semis were 17%. Detached houses were nearly 36%, and flats of one kind or another were close to 37%. So the usual terrace advice (a dormer on the back and you're done) only fits a small part of the town.
Much of the rest is resort-era building. Bournemouth had about 17,000 people in 1880 and about 60,000 by 1900, after the railway arrived in 1870. Boscombe grew fast between about 1885 and 1940, and many of its villas went up as holiday or retirement homes. Winton started as small artisans' cottages built by the Talbot sisters in the 1850s, and the Moordown avenues named after George V's coronation came after Burt's Farm was sold around 1911. Council estates such as West Howe followed from the late 1940s.
If you live in a flat, the picture changes completely. Flats have no householder permitted development rights, so any change to the roof above a flat, even a rooflight, needs a planning application.
Twenty conservation areas, mostly where the best roofs are
BCP Council lists 20 conservation areas in Bournemouth itself. Most of them are residential, from Dean Park and The Saints to Boscombe Spa and the old village at Holdenhurst. Inside any of them, a roof extension is not permitted development. You need planning permission for a dormer of any size.
Meyrick Park and Talbot Woods is the big one, around 228 hectares. Its appraisal describes big detached villas from about 1870 onwards, Edwardian roads like Bryanstone Road and Talbot Avenue built between 1903 and 1913, and roofs of clay plain tile or natural slate. Big villa roofs like these often have the height already. The planners will want new work to sit quietly on the back slope and match the tile or slate. Get that right and an application stands a fair chance.
Boscombe's older roads, such as Florence Road and Westby Road, are harder. The Civic Society describes towers, gables with bargeboards and complex hipped roofs. Plenty of loft space sits inside a roof like that, but it's broken up, and cutting a dormer through it takes more design work than on a plain 1930s hip.
Matching the conversion to the house
Here is how each type tends to work on Bournemouth's houses. Each has a full guide behind it.
Hip to gable. The natural choice for the interwar detached houses and semis in places like Moordown and the eastern side of Boscombe, where the roofs are plainer. Outside a conservation area it can go ahead without an application if it stays within 50 cubic metres.

Rear dormer. Still the most useful addition on a house with a deep back slope. On a large detached villa it often pairs with a hip to gable. In a conservation area it needs permission, so keep it set well back and clad to match.
Rooflights only. Worth a serious look on the tall Victorian and Edwardian roofs in Talbot Woods. Where the headroom is already there, leaving the roofline alone is the easiest thing to agree with a conservation officer.
Planning. Bournemouth has more planning hurdles than most towns this size. Conservation areas, flats and anything that adds a letting room all need a proper look before you pay for drawings.
Extra bedroom. The usual aim. Bear in mind who will use it. Over a fifth of BCP residents are 65 or older, so think about how easy the new stair will be to climb in twenty years.
En-suite. Where the soil pipe can run decides where the shower goes. Plan it before the steel goes in, not after.
Home office. A quiet room under the eaves. Ask for a data cable to be run up while the walls are open.

L-shaped dormer. Less common here simply because terraces are. Where a Winton or Boscombe terrace has a back addition, a second dormer over it gives you room for a shower.
Mansard. Always a planning application, and a hard sell on the villa roads, where the appraisals care about the shape of the roof. Get an architect involved early if you want one.
Cost. We don't publish a Bournemouth figure. A slate villa roof in Talbot Woods and a 1930s hip in Moordown are different jobs, and a single number would mislead you. Three site visits will.
BCP Council and the sign off
Since April 2019 planning and building control for Bournemouth have sat with BCP Council, which also covers Christchurch and Poole. All three share one online planning register. Search your road on it before you commission drawings. What the neighbours got approved, and what they had refused, tells you more than any guide.
Building control is the council's own team, based at the Civic Centre on Bourne Avenue. The council asks you to make an application before contacting them, then uses an online enquiry form. When the final inspection is done you get a completion certificate. Keep it with the deeds. The council warns that three private approvers, JHAI, Assent and Oculus, have stopped trading, so if one of them was signing off your job, check where you stand.

Questions people in Bournemouth ask
I own a flat in a converted Boscombe villa. Can I use the loft above it?
Possibly, but never without a planning application, because flats have no householder permitted development rights. If the building is in the Boscombe Spa, Boscombe Manor or Knole Road conservation area, expect the council to look closely at any change to the roof.
Can I add loft bedrooms and let them to students?
Letting to up to six unrelated people as a shared house is a change of use. A direction in force across the whole of Bournemouth since December 2011 removes the right to make that change without permission. Apply for that first, then build.
Could the loft become a separate flat?
That's a new home, not a loft conversion, so it needs full planning permission. It also brings in the Dorset heathlands rules. Within 400 metres of protected heath, new homes are strictly controlled. Between 400 metres and 5 kilometres, any net increase in housing has to pay towards heathland mitigation.
The previous owners converted our loft. How do we get the paperwork?
Ask BCP building control. Building control records aren't public, but an owner can request completion certificates and decision notices from the last 15 years, for a search fee.
