What can I say really, just an absolutely outstanding job in every aspect! David help us with the design, gave us great ideas and was really flexible to really make it exactly as we wanted. He is professional through and through and a lovely guy to deal with. The work is incredibly precise and even better than I could have imagined. Top quality materials and all round workmanship. I cannot recommend him highly enough. Job was done in under a week and the place was left spotless.
Cheers David!

David has just completed his third job for us. He modified our dog pen, built a new decking area and today has just finished a fantastic fence on our boundary line. David's workmanship is second to none, he pays great attention to detail and is hardworking. He didn't even mind our dogs stealing stuff from him!! Have no hesitation in recommending David.

David done an absolutely fantastic job on both. A very hard working and honest fella that knows exactly how to make a sturdy deck. From the moment he starts he gets stuck in ,he does the job in professional way taking care that it's done right. The transformation it has made in our garden is unbelievable. 
I would have no hesitation in recommending him to friends family or even strangers for that matter.
Thanks again David , 1st class.

David has blown us away with the design and quality of our deck - a really awkward sloping back garden has become a fantastic space for us to entertain and relax. I cannot recommend this guy highly enough - a pleasure to work with, so professional and left the area spotless.

David built my split level decking a few weeks ago. The deck is absolutely stunning, David is very meticulous and the attention to detail was fantastic. The deck was build to cover a steep sloping back garden which we have never been able to use as a garden. I'm delighted now to have it finished and my outdoor furniture and outdoor bar all built and I am looking forward to some good weather to make good use of our new space. Thank you David, you done a fantastic job and I am extremely happy with the results.

David did a fantastic job creating a deck at the back of my townhouse.  There wasn't much space to work with  but he came up with an innovative design and the finished result is far better than I could have  imagined.  I can now enjoy the back of my house and the spectacular views I have over the city. Highly recommend David to anyone.
