    Hello Robin,

    I spoke with you over the phone and you advised your business partner would call to discuss? I didn't recieve a call and have tried to call you back again since.

    I have responded to your message regarding the query.

  • Single storey Kitchen Extension circa 20sqm

    Not having a clue where to start, Paul took us through the steps needed for our kitchen extension. The package we chose from Bricks and Pieces was perfect for our needs. Paul’s team presented a design that gave us more functional space and maximised our budget. I was optimistic about hiring a company to take on the project as a whole (I’m a bit of a control freak) However, the cost to hire Paul to take on the entire project is almost given back through savings made by simply handing the project over to Bricks and Pieces. Looking forward to the build to be completed, and while it’s all happening, I’m just going to kick back, with a brew and watch. Cheers Paul.

  • Extension

    I spoke to Paul regarding drawings and a quote for a single storey extension replacing my original conservatory.
    Paul advised me on keeping the original conservatory putting a new insulated roof on and building back a couple of new walls making it a perfect spare room to use all year round
    Paul came out within the hour and talked me through the new improvements to the conservatory, he was very helpful and his 40 years in the building game shone through. Paul has saved me a considerable amount of money 💰 and time, the contractor is calling on Saturday for a final walk through and plan of action and official quote .
    It was nice to meet such a professional, honest, genuine and helpful man who clearly knows what he is talking about.
    We are looking forward to working together and i will certainly be leaving another review once the work has been completed.
