Home extensions in Caversham built by Stephen Anthony Developments. Single storey, two storey and wrap around extensions, from the foundations up to the final decoration, with one team on site throughout.
A single storey extension is the usual way to open up a kitchen or add a family room. A two storey extension gives you a bedroom above as well, and often costs less per square metre because you are only paying for one roof and one set of foundations.

More Information
Before any walls go up we dig and pour the foundations. How deep depends on the soil, nearby trees and any drains running under the plot. Building control inspects the trench before concrete goes in. Getting this stage right is what stops movement and cracking later.
A good extension does not shout. We match brick, mortar colour, roof tiles and window styles to what is already there so it reads as part of the house. On older properties the mortar mix matters as much as the brick, and we will bring samples before ordering.
Home extensions have been the backbone of our work for most of our 34 years. We have built onto every kind of house around Caversham, from small terraces to large detached properties. The same team handles the dig, the brickwork, the roof and the fit out, so nothing stalls waiting for the next trade.

Written quotes before any work is agreed
Often not. Many single storey rear extensions fall under permitted development if they stay within size and height limits. Two storey work and anything on a listed property or in a conservation area usually does need an application. We will tell you which category yours falls into.
Yes, in most cases. The extension is built as a separate box alongside your house, and the wall between only comes down near the end. That last part is the disruptive week. We plan it with you so you are not without a kitchen at a bad time.
It varies by property and area, but extra floor space and a better layout are usually the two things buyers pay for. A well built extension that matches the house adds more than a cheap one that does not. Speak to a local agent before you finalise the size.
