10 Kitchen Renovation
Posted 01 April
Job location: SG8We used Blackstone Developments for our new kitchen space and are so happy we did! They supplied & installed our kitchen aswell as carrying out the renovation of the kitchen area. Joe was great in helping us design the kitchen and went out of his way to keep us up to speed throughout the whole process. We are over the moon with our new kitchen & would happily recommend Joe & the team to anyone wanting work done!8 New kitchen works in barn conversion
Posted 31 March
Job location: SG8Joe and his team carried out works to our house by stripping out the original kitchen and adapting the facade to include a new window. New acoustic boarding and insulation was added to the double height party wall and plastering and decs were carried out throughout the kitchen area along with plumbing and electrics for the kitchen. Our house is a barn conversion with lots of exposed timber so it was not a straight forward job. All of their works were done well and at a good price.
