Extensions- 3 Jun 2020
Mohit and his team at Shivay Developments completed extensive improvement work in my house (rear extension, internal structural work, kitchen, toilet, boiler installation, plumbing and electricals, flooring & finishing). The end result exceeded all my expectations in terms of cost, time and quality making me a very happy man. Sharing some pictures would have done proper justice but unfortunately there doesn’t seem to be a way to upload pictures with the feedback. In spite of living inside the property whilst the works were ongoing, we hardly felt any impact owing to how well Mohit had planned the whole thing and the advance notices he used to give us from time to time. All the guys too were very considerate when it came to minimizing the inconvenience all the dust and noise could cause to us and also the neighbours. I also liked the fact that nothing was rushed and a great deal was given to attention for details and the result was just splendid. I guess at the end of the day, it’s what you see that matters most. However amongst everything that hit the right notes for me during the entire process, it was the confidence that I can trust this team to do the job right stood out. It was a bunch of warm and friendly people who had direction and knew what they were doing. A special mention and a big thank you to Kash and Pala to lead the work from the ground up and Mohit for taking up and managing the job and of course for the celebratory rounds of beers :) Do keep in touch

Fletcher and his team did a 5 metre extension on my kitchen, installed a new kitchen, new doors and new floorboards throughout the downstairs. All members of his team were absolutely outstanding. The workmanship looked extremely professional and it turned out so much better than I expected. If there was ever a problem, it was never a case of ‘we can’t do that’ there was always a solution and I never felt stressed as I knew that whatever cropped up, they dealt with it. They were all so friendly and I felt at ease with them all the time. When I went to work, I left them to their own devices and they always locked up perfectly for me. I can’t recommend them enough and I will certainly have them back when I need more work completing.

What to ask a The City extension builder before hiring?

Before hiring an extension builder in The City or extension building company in The City, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in The City?

An extension builder in The City should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your The City extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in The City?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the The City extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most The City extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
