Extensions- 14 Nov 2019
Bogdan himself is extremely knowledgable and his years of experience in industry is clear to see, which makes choosing him great value for money. Before and during the project he offered solutions that we hadn't considered and the would in fact save us money and be of benefit to us in the future. His team is punctual, reliable, diligent, speedy and clean! They take pride in their work which has led to a highly satisfactory work in the final build. Bogdan also has great connections to third parties (e.g. to flooring and curtains/blinds providers) which is very valuable, especially when trying to coordinate different aspects and timings of a full house redecoration. His quotes and payment structures are fair, clear and concise which is also very helpful. His communication is excellent too. All in all, Bogdan's great work took away a huge amount of stress during these projects. I would highly recommend Bogdan and his team for any prospective works someone is considering.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Job was to convert WC in outbuilding into a full bathroom, do walls and ceiling in outbuilding to convert into an office space. Price was agreed with things planned, still with some issues towards later part of job, It worked out in the end. Overall I am giving 3-4 stars as quality of work is good. Just need to have things written down with him, and a thorough discussion on plan before commencing work and agree on payment plan. suggested to keep 20% to be paid at completion.

Euro Build Ltd

Extension Builder in Alfold
Hi there just a bit about me. Well I’m a time served Carpenter / Joiner by trade and have worked my way up to now owning and running my own company’s for the past 25 years. I have employed up to 20 employees at any one time and build projects from £20k up to £12m for individual clients. So i know how to run a construction company and how to get the job done, but more importantly i believe i understand the stress and pressure all clients can endure if there build is not built within budget and within an honest time line. Everything we do is insured to the highest standards and our workmanship is second to none. I have decided to now move away from the large build sector and back to the smaller more personal builds as this is where i get the most satisfaction and believe I can offer the best service to the client, a happy client is a happy builder. Our work area is anything to do within the construction of your home, even down to the design and getting engineering across the line. Best regards Rod Moran

What experience do you have with similar extensions in Alfold?
