Lean-To Conservatories

Lean-to conservatories are a popular choice for their affordability and range of customisations. Ideal where space is at a premium, they suit both modern and period homes. Create a unique lean to with your choice of doors, windows and decorative finishes.

The reinforced, durable uPVC in our lean to conservatories make them strong and long-lasting. Opt for a glass roof to maximise light, or browse solid roof options for increased insulation. We also offer replacement roofs for your existing lean to conservatory.

Lean-to conservatories are the easiest and most affordable way to add space to your home. They have a flat, slanted roof that sits at an angle between the roofline and your exterior wall. They offer great style flexibility and are a great way to make use of more awkward spaces.

Benefits of a Lean-To Conservatory

  1. Affordable and Value for Money

    The construction and smaller size of lean-to conservatories make them an affordable way of increasing space and light in your home. A well-planned stylish lean-to helps increase home value, and combined with their affordability they make a great value-for-money investment.

  2. Slanted Roof

    The slanted roof on a lean to conservatory means more effective water run-off. This makes them easier to clean and maintain than traditional hipped conservatory roofs. This saves you money and hassle over time and potentially means the roof lasts longer.

  3. Flexible Space

    A modern lean-to conservatory is a versatile addition that can fit into even awkward spaces. Create a bright new space that connects the dining room and kitchen of your terraced home. Or add a sunny new playroom or home office off your main living room.

  4. Year-round Use

    A lean-to conservatory tends to be smaller, sometimes incorporating two of your external walls, making them better insulated for year-round use. Our solaroof glass keeps your lean to cooler in summer, while solid roof options help keep a lean-to at a comfortable temperature all year.

Our solaroof glass blocks more heat from the sun than conventional glass, helping keep your room cooler in hotter months. It also blocks UV rays to a minimum, protecting your furniture from fading and warping. Solaroof technology reduces glare, so you can sit and read in comfort, even in full sun.

Your Questions Answered by Us

Can a lean-to conservatory have a tiled roof?

Yes, a lean-to conservatory can have a tiled roof. With an Anglian lean-to conservatory, you can choose a solid tiled roof, whether for a new conservatory or a replacement roof. Our solid tiled roofs feature replica slate-effect tiles. They are available in three different shades: Carbon Grey, Rich Harvest Brown and Deep Red Terra Brick.

How big can a lean-to conservatory be?

Anglian lean-to conservatories are always bespoke to fit the size you want them. That said, they tend to have a maximum width of 10m and maximum projection from your home of 4m.

Do I need planning permission for a lean-to conservatory?

Most of the time a lean-to will not need planning permission, because it is a smaller construction. A lean-to built at the side of a property must be narrower than the width of your home to be classed as a permitted development. You might need planning permission if it covers more than 50% of the area your home covers. You will also need permission if it is more than three metres high, extends more than 6 meters out from your home. Take a look at our full guide to conservatory planning permission for more information.
