Started on time and completed the decking extension & renovation to a high standard. Ensured that small details like cuts around poles etc, were finished properly and not left with gaps. Next time I would confirm that clearing rubbish is part of the quote, but highly recommend Przemek for quality finish.

Architecture- 4 Jun 2026
I recently worked with this structural calculation engineer for a project that required precise drawings, and I couldn’t be happier with the outcome. The calculations were spot-on, and the drawings were clear and detailed, making the process seamless with my builders. Not only was the quality top-notch, but the pricing was fair and transparent. Communication was excellent throughout, and they delivered on time. Highly recommended!

I recently had extensive work completed in my flat by Vas, and I couldn’t be happier with the result. The service was excellent from start to finish. Not only was the quality of the work consistently high, but the whole experience was smooth and stress-free. What really stood out was Vas’s level of skill and versatility. Every aspect of the project was handled with care and professionalism — from plumbing and new water heating pipes, to new electrics, installing a new kitchen, laying a beautiful wooden floor, renovating the bathroom, and even replacing doors with a sliding door system. Each element was completed to a very high standard. On top of that, Vas was friendly, proactive, and easy to communicate with throughout. Nothing ever felt like too much trouble, and it was clear he takes real pride in delivering great results. It was genuinely a pleasure to deal with Vas, and I would highly recommend his services to anyone looking for reliable, high-quality work. Thank you again!
