  • Architect

    Darren was absolutely brilliant from start to finish. Knowledgeable and a consummate professional. Flexible and totally approachable. Recommend him to other developers and will be using him again on the next project myself. Oh and price was more than reasonable. Overall rating triple A.

  • Extension planning

    Darren has been fantastic. He's very professional yet friendly which is why we liked him from the start. He is very good at his job, and he responded to the huge amount of emails I sent him very quickly. We would highly recommend Darren and will use him again for any future plans.
