A bungalow in a terrace
No other town has quite the same house. The Sunderland cottage is a single-storey terraced home, built mainly between 1860 and 1910 for skilled shipyard workers, and it carried on into the 1920s and 1930s. You know one by the front door opening into a narrow passage, the "Sunderland doorcase", with rooms either side and a kitchen and bedroom behind. Whole streets survive in Millfield, Pallion and Hendon, and in Fulwell's "Scottish streets" built in the 1920s.
A council housing survey put cottages at a little over 4% of the city's occupied homes. Owners have been putting bedrooms in their attics for generations, and some box dormers fill the whole roof.
For a loft, the cottage is an odd case. There's no upstairs to borrow a staircase from. The whole house sits under one slate roof, so the new stair has to find room somewhere in a narrow ground-floor plan, and the new floor goes in over ceiling joists that were only ever meant to hold up a ceiling. Sort out the stair before you talk about dormers.
The front dormer question
Walk along a cottage street and you'll see some fronts with dormers and some without. Under national permitted development rules, a dormer on the roof slope facing the road always needs a planning application. On a cottage street that puts every new front dormer in front of the council.
Sunderland's Development Management guidance, adopted in 2021, is blunt here. It says front dormers on Sunderland cottages "will not normally be considered appropriate". It then sets a test. A front dormer is only in the running where at least half the cottages in that terraced block already have one, and it can still be refused then. Count the houses in your block before you pay for drawings. If fewer than half have front dormers, the council says it will refuse, even if the count falls only just short.
The back is a different matter. On a cottage outside a conservation area, a rear dormer within the 40 cubic metre limit for terraced houses is normally permitted development, with no application needed. Get a lawful development certificate anyway.
Which conversion suits which Sunderland house
Rear dormer. The usual way to get standing room over a cottage, and the only dormer most cottage owners can build without an application.
Rooflights only. Fine where the pitch already gives headroom, as on many of the taller Ashbrooke and Roker terraces. Over a cottage the roof is often too low for rooflights alone, so ask the surveyor to measure before you get attached to the idea.
Extra bedroom. Turning a two-bed cottage into a three-bed is what most local loft work is for. Settle the stair and the fire escape route at the design stage.
L-shaped dormer. Cottages and older terraces here usually have a rear offshoot that once held the washhouse. A dormer that runs over it as well can find room for a shower, but it pushes you closer to the 40 cubic metre cap.
Hip to gable. Semis are the biggest single group of houses in the city, close to two in five in the council's survey. Where one has a hipped end, squaring it off usually makes the loft usable. Local guidance is silent on it, so national rules decide.

En-suite. Work out the soil pipe route first. In a cottage it has to drop through a single storey into a long, narrow plan, and where it lands decides where the shower can go.
Home office. Suits a cottage attic too tight for a proper bedroom. Run data cable up while the ceilings are open.

Mansard. Rare here, and it always needs permission. The council's guidance wants extensions to stay subordinate to the house, which a mansard rarely does.
Planning. Front dormers always need an application. So does any dormer or hip to gable in the city's conservation areas, and the two listed cottage terraces on James Armitage Street and Ridley Terrace need listed building consent too.
Cost. We don't publish a Sunderland price. A cottage needing a new stair and a semi needing a hip to gable are different jobs. Three site visits will tell you more than a figure on a web page.
Slate roofs, Article 4 and sign-off
Sunderland has 14 conservation areas. Ashbrooke, designated in 1969, is the largest. The others include Roker Park, Bishopwearmouth and Sunniside in the city, and old village centres such as Ryhope and Washington. Inside any of them a dormer needs planning permission, front or back, and so does a hip to gable.
Roker Park and parts of Ashbrooke go further. Article 4 directions on the park-facing terraces at Roker, including Park Parade and Roker Terrace, and on Azalea Terrace North, Belle Vue Park and The Elms West in Ashbrooke, take away the right to change a roof's shape or materials without permission. Both appraisals want Welsh slate kept or matched, so price natural slate for the dormer and any patching.
Building control is run by Sunderland City Council from City Hall on Plater Way. Give them two days' notice before work starts, and a completion notice within five days of finishing. No notices, no completion certificate.

Questions people in Sunderland ask
Half the cottages in my block have front dormers. Will the council approve mine?
It's possible. The council's guidance treats 50% of the terraced block as the minimum before it will consider a front dormer on a Sunderland cottage, and says it can still refuse above that. Matching the existing dormers gives you the best chance. Check the neighbours' approvals on Planning Online first.
I live on James Armitage Street or Ridley Terrace. Can I convert the loft?
Both are Grade II listed terraces of single-storey cottages, among the few Sunderland cottages with that protection. Any alteration affecting their character, rooflights included, needs listed building consent on top of building regulations. Talk to the council's conservation team first.
Can I use concrete tiles on a dormer in Roker Park or Ashbrooke?
Not on the terraces covered by Article 4 directions without permission, and you're unlikely to get it. Both conservation area appraisals ask for Welsh slate, or a natural slate that matches in size and colour. Roker's appraisal says synthetic slate is always refused.
My cottage's attic was turned into a bedroom decades ago. Does that count as a loft conversion?
Only if it was done with approval. Cottage attics have often been made into bedrooms over the years. If yours has no paperwork, Sunderland's building control does offer a regularisation application for unapproved work. Ring them before you apply.
