"Following the initial consultation, I asked Mark to take on the build because he understood exactly my vision for the project. I was unfamiliar with building codes and procedures but he explained everything. Mark was detail orientated at each stage, promoting the highest quality products to use during the build. I would highly recommend Mark for his professionalism, knowledge, skill in cost control and project management capabilities when overseeing construction works. He delivered exactly what I envisaged and to the highest quality. I cannot recommend Mark of Katlan highly enough."

"Having worked closely with Mark on various developments in the London area we found him to be a very conscientious developer who builds high quality apartments in a timescale not matched by any of his rivals. We would have no hesitation in working with Mark and his team again in the future and hope to do so."

Highfield acquire and dispose on average around 50 development sites per year and Mark has always been extremely accurate on his market appraisal and one of the first parties to respond with detailed and qualified offers. In his new role at Katlan Construction Cost Consultancy, I would highly recommend his services.  He engages on projects in a professional and considered manner and due to his extensive knowledge of planning and construction he will be able to provide a high level of service. We wish him all the best in his new venture and will be recommending his services."
