How much is a gull wing conservatory in Teesside?

£12,000 to £20,000 fully fitted. It sits between a lean-to and an Edwardian in price because of the shaped roof structure.

My bungalow eaves are very low. Will a conservatory fit at all?

Almost always. The gull wing exists precisely for this: the shallow first pitch tucks under the eaves, then the roof rises. Very occasionally a soil pipe or window needs moving first, which a measured survey flags before you commit.

Is a gull wing better than a lean-to?

For interior feel, yes: the rising roof gives a vaulted ceiling and a taller glazed front, so the room feels bigger than the same footprint as a lean-to. A lean-to wins on simplicity and price. On most bungalows the gull wing is worth the difference.

Does the shallow roof section leak?

Not when designed properly. Modern roof systems are rated for low pitches with the right glazing bars and flashing. Leaks come from poor wall plate fixing and flashing, which is why the quote should describe both.

How long does a gull wing take to build?

Typically 2 to 4 weeks on site, much the same as a standard conservatory. The roof structure adds a day or two over a plain lean-to.

What a gull wing actually is

A gull wing solves the most common conservatory problem on Teesside: not enough wall height. A standard conservatory roof needs fixing height on the house wall that bungalows and many dormers simply do not have. The gull wing roof starts at a shallow pitch under the low eaves, then sweeps up to a steeper pitch away from the house, so the room still gets a proper vaulted ceiling and the glazed front gets its height back.

Teesside has more of this housing than almost anywhere: the post-war bungalows of Thorntree, Netherfields, Ormesby and the older parts of Guisborough, Redcar and Hartlepool. For all of them, the choice is usually gull wing or lean-to, and the gull wing gives the more generous interior.

What they cost on Teesside

Expect £12,000 to £20,000 fully fitted. The shaped roof structure costs more than a plain lean-to roof but less than a full Edwardian or Victorian build. The main variables are the width of the span, the roof glazing specification, and whether the shallow section needs structural support at the house wall.

What a proper gull wing quote specifies

The roof design: the two pitches stated, the structural support for the transition, and confirmation in writing that the design clears your eaves, soil pipes and first-floor windows, worked out from a measured survey.
The base: foundations and floor build-up matched to the bungalow's slab levels, so there is no awkward step into the room.
Roof glazing: glass specification with U-values, solar control where the aspect needs it, and ventilation, because the lower ceiling at the house end needs airflow designed in.
Frames and doors: the frame system, door type and position, and how the shallow roof section is flashed against the house.
Certification: frame and glazing guarantees in writing, with FENSA or equivalent paperwork for the glazing.

Planning permission, usually not needed

A gull wing to the rear of a bungalow, single storey and within permitted development limits, normally needs no planning application. Bungalows in conservation areas are the main exception. The planning guide explains the limits.

Gull wing vs the alternatives

Choose a gull wing when low eaves rule out a standard pitched roof but you still want height and light inside. Choose a lean-to for the simplest low-eaves solution at the lowest price, or an orangery with a flat perimeter roof and lantern if you want the room to feel more like an extension. The styles guide compares all six styles.
