A conservatory installed in Cardiff in 2006.

This superb conservatory was the dream of one of our customers.
Finally in 2001 it came true.
Due to the ground we excavated and removed over Fifty tons of soil in order to build the new base and retaining walls.
Aluminium box guttering was used to overcome design problems normally associated with bungalows.
We first installed windows in this property in October 1987.
We installed this conservatory in 2001
We are now installing more windows in 2006.
Mrs Robinson said there is no other company we will trust other than Welsh windows.
We were one of there very first customers in October 1987 and have always been extremely happy with there level of customer service and high installation standards.

This superb gable ended conservatory was designed for a qualified surveyor.
We had replaced his windows in 2000 and carried out many repairs and installations for his business over many more years.
John said there was only one company we would trust to build and design our sunlounge. After working with Welsh windows for many years we knew we would have a first class installation.
A Specialised roof glass was used that no only helps stop the sunlounge from overheating it has a special coating on the outside which means the roof cleans itself.
You also do not get the noise associated with normal poly carbonate roofs.

Planning Permission and Conservatories

A large amount of conservatories do need planning permission.

Whether you need planning permission or not for your conservatory depends on many factors. A detached / semi detached house can add up to 70 cubic metres or 15% of the un-extended house volume up to a maximum of 115 cubic metres A terraced property can add up to 50 cubic metres or 10% of the un-extended house volume up to a maximum of 115 cubic metres.

If the house already had some form of building work the size of that extension must be subtracted from the total that is available for your type of property. Do you live in a conservation area or a listed property. If so then you must seek planning permission before undertaking any conservatory extension.

Some newer properties have had there automatic planning permission rights for extensions already removed – in which case check with your local council beforebuilding your conservatory.

If the conservatory is more than 4m high in any place then it cannot come within 2m of your boundary.

The conservatory cannot cover more than 50% of the size of the garden before the conservatory was installed.

If you have a Garage which is not attached to your main building with an access door into your home, then the volume of the garage must be taken and subtracted from your 70 cubic metres. This usually means in reality you need planning permission.
If you don’t need planning then all glass used must be toughened glass.

The extension has a completely transparent or translucent roof.

At least 50% of the walls must be glazed.

75% of the roof must be of a translucent material, Polycarbonate, glass or similar.

The extension must be at ground level.

The extension is permanently separated from the remainder of the property by means of a door or doors.

Above rules can change or may not apply dependant on your local planning authority. Note Scotland has slightly different regulations.
