How much would a Kitchen Extension Cost?

There are no two extensions that are the same. There are also variations in materials and design ideas. Some customers want UPVC and others want Aluminium. Some want Lanterns and others want Velux windows. This is why the price can vary so much. If you have building plans, we can provide a quotation for free. We can also provide planning drawings at an additional cost if required.
