In a nutshell, Marius and his team are great. They're kind, respectful and Marius is always available to answer every question you have - he def is the most knowledgeable builder I've spoken to. You get a very transparent estimate and sign a contract, for both parties' peace of mind. If extras come up, Marius openly discuss them with you before taking any action - my job required quite a few and Marius was also great to stay competitive price-wise whilst keeping the quality of the work sky-high.

Norbert and Raymond delivered a very prompt quotation which was sufficiently detailed for me to make a decision on the work. They were keen and diligent throughout the project, working hard for a very fair price. Their attention to detail was excellent, they didn't skimp on quality and worked tirelessly for 7 continuous days to deliver as promised. I'm very pleased with the end result - a paved terraced garden engineered with drainage channels, brickwork and timbers. I can definitely recommend them for similar work.
