The Lean to Conservatory - Prices & Planning Permission

inside a lean to conservatory

If you’re looking for lean to extension ideas then a conservatory is the ideal choice for a bright and airy addition to your home and is one of the most cost effective conservatories on the market. With its simple shape and lack of ornate detailing, a lean to conservatory is perfect if you want a modern option that provides plenty of space.

This is a popular model of conservatory in the Mediterranean as it makes the best use of the sunlight available.

Characteristics of lean to conservatories

Lean to conservatories are either square or rectangular, with a flat roof that slopes downwards. This shape gives it the appearance that it is leaning against the wall of a house, hence the name lean to. They can be made up of a number of combinations of walls and panes – with some featuring a dwarf wall and others being fully glazed on 3 sides.

In many cases the sloping roof will also be glazed, however it is not uncommon to see tiled roofs on a lean to conservatory.

Benefits of lean to conservatories

The biggest benefit of the lean to conservatory is the amount of space it can provide. Due to its straight edges and lack of ornate detail it can be one of the brightest and most airy conservatory styles – especially when you opt for a glazed roof.

Due to its simplicity the lean to conservatory can be very affordable and is a great alternative to building a full extension onto your home. Plus there are some great decorating for lean to conservatory ideas on Pinterest that are worth a look to really make your new room shine.

Do I need planning permission for a lean to conservatory?

To avoid the need for planning permission for your new lean to conservatory, you need to follow the guidelines below:

  • No extension forward of the principal elevation or side elevation fronting a highway. This means that any conservatory on the front or side of a house that will be closer to a public highway than the original house will need planning permission. A highway is any public right of way including footpaths.
  • On designated land no permitted development for rear extensions of more than one storey; no cladding of the exterior; no side extensions.
  • Maximum height of a single-storey rear extension of four metres.
  • No more than half the area of land around the “original house” would be covered by additions or other buildings.
  • Maximum depth of a single-storey rear extension of three metres for an attached house and four metres for a detached house. The width of a conservatory running along the back length of a house is not constrained at all unless it projects beyond the house which is constrained by rule 3. A house is only detached if there is no solid structure connecting it to a neighbour. A “link” house is therefore not detached nor are two houses with a common garage. The rules on what counts as being detached have not changed from the previous ones.
  • No verandas, balconies or raised platforms.
  • Side extensions to be single storey with maximum height of four metres and width no more than half that of the original house.
  • Maximum eaves height of an extension within two metres of the boundary of three metres from the lowest point on the ground.

Lean to conservatory prices

Orangeries UK estimates the cost of a lean to conservatory to start from £5,000 for an uPVC version or £8,000 for hardwood. Another choice that could impact the cost of a conservatory is the kind of window used, with choices including single, double or triple glazed as well as polycarbonate options.

Materials are not the only factors affecting cost – you should also consider the size of conservatory you want, as well as if it will feature a dwarf wall or full height glass.
