DIY Lean To - Star Rating 4/5

Lean tos are a great way to build your new conservatory and obvisouly dont require a conservatory installer. Witht basic DIY knowledge and installation guides, you should be capabale of doing it yourself and some of the other features such as double glazing. Whilst some people may just not want the hassle of the build and employ someone to build their lean to conservatory roof, many people choose this type of conservatory due to its relatively easy assembly. There are various glazing options available but most people go for fully glazed for insulation purposes.

Self-build lean to sunrooms are a popular option for those wishing to add extra space to their home. A DIY conservatory can save you a considerable amount of money with self build prices being considerably cheaper than supply and fit conservatories.

lean to conservatory kits

There are a range of DIY conservatories that come supplied with easy to follow instructions. You may wish to hire a professional to build a dwarf wall or lay foundations if you are not confident in those aspects, then continue the rest of the build yourself. Compared to Edwardian, Victorian or DIY orangeries, the lean-to is the most simple design for a home extension.

The Roof - Star Rating 5/5

Unlike lantern roofs, the roof of a lean to sunroom slopes away from the building. This allows rain to run off whilst also being adaptable to suit the building it is to be attached to. The degree of the slope can suit your personal needs, with a shallow pitch being ideal for bungalows, whilst a steeper lean is ideal for terraced or detached houses.

The roof of your lean to can be constructed of either glass or polycarbonate, or occasionally it can be tiled.

Polycarbonate Vs Glass Roof

Polycarbonate roofs are cheaper than glass conservatory roofs, although they have the drawback of being less soundproof and less thermally efficient. Glass roofs are more aesthetically pleasing whilst having the added benefit of allowing more light into the conservatory. Tiled roofs have the drawback of letting less light into the conservatory, however, they are more soundproof than polycarbonate. Whilst you do not need planning permission for a glass or polycarbonate roof, a tiled roof may require permission. Its important that you browse the conservatory roofs as you do not want to pick the wrong one.

The cost of Edwardian conservatories tend to be more expensive than a lean to conservatory. They can take on different shapes and sizes compared to the rectangular lean to. A lean to is ideal when space is limited, particularly if you live in a bungalow. Edwardian conservatories have apex roofs, which if you live in a bungalow, means it would not meet building regulations if the apex is higher than the bungalow roof.

Lean to conservatories are easier to install than an Edwardian conservatory and are more suited to a self-build project. Double glazed is always recommended to keep the heat in during the colder months.
