Garage Conversions in Addlestone.
A garage conversion adds a room inside the existing building, which helps on the small and average plots of Runnymede's older suburbs, where garden space is worth keeping. If your house in Addlestone, New Haw or Woodham has an attached or integral garage, it can become a study, playroom, utility or ground-floor bedroom. On site, a single garage conversion takes 3 to 5 weeks, and a double garage or one needing structural alterations takes 5 to 8. The work normally includes an insulated floor, an infill wall with a window where the garage door was, and new heating, lighting and power, with the foundations checked under the new wall.

Our focus in Addlestone.
Converting a garage often needs no planning permission, but a newer development may have a condition that keeps garages for parking or removes permitted development rights, so the planning history comes first. In a conservation area, the infilled front should match the house, as cladding or render there needs permission. Every conversion needs building regulations approval, through the council's in-house team or a Registered Building Control Approver, and we manage it as part of the project. If the house sits in a higher flood zone near the Addlestone Bourne or the Wey, the floor level and finishes of the new room are worth settling early.
As a design-and-build company we take on a limited number of projects at a time, so that every one gets the attention it deserves. If you are planning work on your Addlestone home, we would like to hear about it.

“Very helpful, proactive and competitive design/build quote. The initial video consultation was very useful, and Conor was very proactive in following up on my questions. The detailed cost breakdown was very helpful in understanding where I could perhaps reduce costs. If you are looking for a design and build company to discuss your project, I have no hesitation in recommending Conor and the Grand Innovations team.”
