Architecture- 13 Apr 2015
We are extremely happy we chose to use Phil for our loft and extension design. Phil is professional, extremely accommodating and a pleasure to work with. He was always contactable, punctual and happy to spend a lot of time with us to discuss designs and the planning process. His design ideas were smart and he presented us with a number of workable options. We wouldn’t hesitate recommend Phil and would certainly use again for any architectural works.

Extensions- 4 Aug 2020
On a cold November evening, Tony and his team turned up to provide a quote and within a week this was received. The quoted price came in the middle of the pile, which was a good start and aligned closely to the ballpark figure I'd received from a friend who was also in the trade. We then visited a site they were finishing off, and Tony had the confidence to ask us to speak to the client without him there and they gave us the confidence to proceed. They started in January 2020 and rapidly moved through the works and engaged closely with my architect, Structural engineer and building control and proceeded based on their recommendations strictly. We lived in the property as build progressed and the team ensured that the site was secure every evening and we were safe. As COVID-19 hit and we went into Lockdown, the team continued to come and work (we were separated from them as the house was boarded up) and the only challenge was getting supplies. Tony scoured all over London, picking up items as best as he could and work continued. Once they'd broken through into the old part of the house they continued to progress rapidly and showed utter professionalism. The team lead's attention to detail is impressive, and he gave great recommendations on what would be the right approach when we were laying out features such as window sizing and lighting. The standard of work is excellent and I would highly recommend them.

Loft Conversion- 6 Sep 2024
I recently worked with Ardit from AK Constructions and Developments on a double dormer loft conversion, which included creating two large bedrooms, a bathroom, and a utility room. I'm delighted with the results; the quality exceeded my expectations, and everyone who's visited has been impressed. Ardit's approach was professional and not pushy, unlike other builders. He provided references and even invited me to see a current project, which convinced me. Ardit was flexible, suggesting changes like moving the bathroom for better functionality, which turned out great. His team, including Edi and Vini, were polite, courteous, and always willing to help. The work finished ahead of schedule, and Ardit sourced excellent tradespeople, making the experience stress-free. I was so impressed that I also asked him to redo my kitchen, and I'm thrilled with the outcome. I highly recommend AK Constructions and Development.
