Lean-to conservatories,
the simplest extra room.

It depends on the size, the roof, the walls, the frames and doors, and what goes inside. We survey for free, draw it up and give you one written price for the whole build. Try a size and see what sets the price. Finance is available at 12.9% APR representative.

Usually, yes. A lean-to’s roof slopes down from a single line on your wall, so it suits bungalows and walls where there isn’t much height under the eaves. We measure your wall at the survey and set the roof pitch to suit.

Usually not. On most houses a single-storey lean-to is permitted development if it goes no more than 3 m beyond the original back wall of the house (4 m for a detached house), stands no higher than 4 m, keeps its eaves to 3 m within 2 m of a boundary, and, with any other extensions and outbuildings, covers no more than half the land around the house. It can’t be higher than the house’s roof or eaves, or stand forward of the front wall, and a bigger one may need prior approval. Flats, listed buildings, conservation areas and some new-builds have their own rules. We check yours at the survey.

Not usually, with a glass or polycarbonate roof: a conservatory is normally exempt if it’s at ground level, under 30 m², with a roof at least three-quarters glazed and walls at least half glazed, separated from the house by external-quality walls, doors or windows, with its own heating controls, and with safety glass and electrics that meet the regulations. A tiled warm roof, or opening it up to the house, needs approval. We apply, arrange the inspections and hand you the certificate.

Yes, if there’s height for the slope it needs. SupaLite’s tiled roof needs from 10° to 12.5°, depending on the tile, and Ultraframe’s Livinroof of insulated panels and glass goes down to 5°. We measure your wall and advise on the best one for yours at the survey. Inside, you get a plastered ceiling with LED spotlights.

Glass lets in the most light, polycarbonate is the most affordable, and a tiled warm roof makes it a room you use all year. See them compared.

Yes. Choose French doors, sliding doors, or bifolds that fold right back and open the whole side to the garden.

Halo uPVC is cost-effective and low maintenance, in white, grey or woodgrain. Aluminium from Smart or Cortizo has slimmer frames for more glass, in any RAL colour.

Yes. Our frames have multi-point locks, internally beaded glazing and toughened safety glass, built to keep the room as secure as the rest of your house.

Yes. Our trusted builder, who has worked alongside us for years, does the groundworks, foundations and brickwork, matched to your house. Or we can put a new roof on the lean-to you have.

It depends on the size and the groundwork, so we’ll give you a timescale with your quote. A new roof on an existing conservatory is much quicker: a simple Ultraframe roof can go on in a day (one customer’s did), and SupaLite says its tiled roof takes 3 to 4 days on a standard conservatory, before plastering.
