What our clients say

"We liked the openness and proactive suggestions from Kris for enhancements to our plans. Provision of a detailed break-down of costs upfront really eased the process. We liked the constant and relevant communication. Consider them your first choice if he’s available!"

Chris Low, Battersea SW11

“We’ve worked with Kris over the past 13 years. His commitment to quality and client satisfaction is total. Our best recommendation is that we recently asked Kris to help renovate a dilapidated house and without Kris being available, we wouldn’t have undertaken such a project.”

Barbara & Peter Stones, Kingston upon Thames KT1

“Kris is great to work with, knows his trade and was always on hand if we needed to talk. His team is exceptional, too. Our project was delivered on time and within the budget. We’re happy with the outstanding work they’ve done and we’ll use them again. We cannot recommend them highly enough.”

Tom Binet, City of London EC1

“There is no one that I can rely on more than Kris and his team to work on my properties. Kris remembers every detail and takes personal responsibility for making sure that the client is completely satisfied with the work. I have worked with lots of building companies and Kris and his team is probably the best”

Anthony Robinson, Clapham SW4
