Torbay has written down what it wants
Plenty of councils leave you to guess. Torbay publishes a house extension design guide, and it takes ten minutes to read. The message is that the new part should stay subordinate, so you can still see the original house.
Some of it is quite firm. Two-storey flat roof extensions "are not considered acceptable". A two-storey side addition should step down from the main ridge and back from the front wall, and the council accepts a minimum of 300mm for both. That stops a row of semis joining up into what looks like a terrace, which the guide says should be avoided. Side walls should be blank and the whole thing should sit inside your own boundary.
Behind the guide sit the local plan and the Torquay Neighbourhood Plan. The local plan's domestic extensions policy says an addition shouldn't dominate the original house or harm its character. Officers weigh light and any overbearing effect on next door's garden too. The neighbourhood plan asks for respect for local height, scale and bulk, and wants enough parking on site. Add bedrooms and the council can ask where the extra cars go.
Hills, culverts and the drainage form
Most of Torbay is a Critical Drainage Area, designated by the Environment Agency, and the council wants a flood risk assessment sent in with most planning applications. Rain off a new roof at the top of the hill can end up in a house at the bottom. For a home in Flood Zone 1 the council has a template form, so the job is usually paperwork rather than a consultant.
Lower down it's more serious. The River Fleet runs in culvert under the town centre, and the council's flood study found flooding behind Teignmouth Road, Winstone Avenue and Firlands Road. In Flood Zone 2 or 3 the Environment Agency's advice for a small extension is a floor at least 600mm above the estimated flood level (300mm where the level is well known), or flood-resistant construction to that height.
Soakaways need care on this ground. Torbay's drainage guide wants percolation tests done to BRE 365, three in a row, at the depth the soakaway will sit, and it lists slopes over 10% and unstable ground as warning signs. Many Torquay gardens qualify on the slope alone. The cliffs at Babbacombe have a record of landslip, so a proper ground investigation comes before the foundation design.
Ten ways to add room to a Torquay house
Roughly in the order they come up here. Each has a full guide.
Single-storey rear. Outside a conservation area and on a house rather than a flat, 3 metres deep (4 metres detached) needs no application, and the prior approval route allows 6 or 8 metres.
Kitchen. Where the garden looks over the bay, the glazing is the reason you're building. Facing a retaining wall in a cut-back garden, roof glass may do more than wide doors.
Two-storey. Always an application in a conservation area, and the council has ruled out flat roofs on this type. Plan a pitched roof set down at least 300mm from the main ridge, and slate if the house has slate.
Open plan. Many older Torquay houses are render over limestone rubble. Cutting a wide opening in a wall like that needs a beam designed for it, with sound bearings at each end.
Side return. Upton and Abbey Road are full of Victorian terraces, where the side passage is often the only spare ground. In those conservation areas any side addition needs permission. Expect a party wall notice too.
Wrap-around. Part side, part back, so check both sets of limits. With a semi, the gap to the boundary is the officer's first question, because of the terracing rule.
Ground-floor bedroom. Getting level access from the road is half the design on a steep plot. Remember the parking question if the extension adds a bedroom.
Home office. Terraced gardens make a separate cabin awkward to reach in the wet. An attached room off the kitchen is simpler, and easier to wire.
Planning. Three questions settle most Torquay jobs. House or flat, inside one of the sixteen conservation areas or not, listed or not. There are no Article 4 directions in Torquay itself.
Cost. No Torquay figure from us. Cutting into a slope and building the retaining walls both show up in a quote, and three builders on site will price them differently.
What the conservation areas say about the back
Inside any of Torquay's sixteen conservation areas, from Warberries and Chelston to St Marychurch and Cockington, the national rules close off side extensions, rear additions of more than one storey and new cladding without an application. Render counts as cladding.
The appraisals show where the council thinks earlier owners went wrong. Upton's notes that 1960s flat-roof additions were "quite extensive". Chelston's calls some in Rathmore Road "unsatisfactory, and visible". On Babbacombe Downs Road, rear additions have cut off sea views from the terraces behind. Up here, the back of your house is somebody else's view.
Flats are different again. A flat has no permitted development rights, so in a converted villa any addition, however small, needs planning permission and the freeholder's agreement. Applications go to Torbay Council planning, and building regulations to its building control team.

Questions people in Torquay ask
Our semi is on a slope. Can we still build 3 metres out without planning?
Usually, outside a conservation area, but the 4 metre height limit is measured from ground level next to the wall. If the garden drops away you may need to step the floor down or apply. A lawful development certificate settles it.
Why does the council want a flood form for an extension on top of Warberry Hill?
Torbay is a Critical Drainage Area, and the worry is the water leaving your plot rather than reaching it. A new roof sends more rain downhill. For Flood Zone 1 the council supplies a template.
Can I put a flat roof on a two-storey extension to keep the height down?
Not in Torbay, as a rule. The council's design guide says two-storey flat roof extensions are not acceptable. A pitched roof set below the main ridge is the usual answer.
We're adding two bedrooms. Will parking come up?
It can. The Torquay Neighbourhood Plan asks for enough parking on site, and the council looks at extra bedrooms in that light. Show where the cars go on the plans.
