Porches are typically small extensions to the front of a house, although they can be much larger and can be built to the side or to the rear. They are generally simple structures of only brick dwarf walls and columns, windows and a door.



Fairly simple structures are usually made of UPVC, although they can be timber or aluminium. Some conservatories require planning permission and some do not.



An orangery, or sunroom, is essentially a conservatory with a solid roof and walls – albeit with plenty of glazing as well. They have the advantage of being sturdy and warm, while also bringing in a lot of sunlight.

Extension - single storey

Single storey extensions are simply an extension built onto a part of the house whereby one side (or more) of the extension adjoins the property and there is only the ground floor plus any basement built to it.


Extension - two storey

A multi-storey extension can, like a single storey extension, also be built to any part of the existing building.


Extension - over-structure

An over-structure extension is, as it sounds, where you are extending over the top of an existing structure such as a garage, a kitchen, a living or dining room.

Extensions in Twickenham & surrounding areas

Green Group Construction specialise in extensions, they are a great way to create extra space. Whether it's to accommodate your growing family, or simply to help you spread out a little. Extending your home is becoming an increasingly popular choice with homeowners who are looking for more space, experiencing a change of circumstance or even just wanting to ‘spruce up’ a tired property.

Extensions normally make the original room longer. This means that natural daylight has further to penetrate into the house as the vertical windows are moved further away. All too often, the original room becomes dark and gloomy and even on the brightest days could mean electric lights have to be switched on.


Green Group Construction use roof windows, you can bring daylight deep into living space, which makes the whole room feel brighter, larger and more welcoming.
