“K&S Design were fast, highly skilled and efficient in the work for us in post extension snagging, decorating and tiling.

Also importantly, they were very accommodating, flexible, and friendly.

I am extremely satisfied with the finished product. Very pleasant builders and a competitive price too.”

“We contracted K&S for a full renovation on our house. The renovation involved gutting the house, installing a new toilet under the stairs as well as installing a new main bathroom and kitchen.

The guys did a fantastic job and really went the extra mile to ensure the finish was fantastic and treated the house as if they were doing the work on their own home.”

You can create new space or reconfigure existing spaces to breathe new life where there are currently small under-used rooms and closets. New kitchens, bathrooms and bedrooms are all popular choices.

Whether you have just purchased a property, or need to completely freshen up your main residence, we are able to completely refit your living space. We can also undertake any conversion or extension to your property, to provide increased capacity.

Before After

"Some people look for a beautiful place, others make a place beautiful."

K & S Design is skilled at structurally adapting and changing your property, but also at implementing the refinements needed to create an impactful finish. A Building Inspector will make visits during the project, to ensure that we abide by all the latest Building Regulations. On completion of all building works, the Building Inspector will issue a Completion Certificate.
