From start to finish A1 developments have provided the highest standard of services you could expect. They were accommodating to our timeframes and really did put our needs as the customer first. The workmanship has been exceptional, so much so we are now having A1 carry out the rest of the work on our renovation project.

Demolition- 18 Apr 2024
Kav was a pleasure to work with throughout. He started off the project so well, we decided to add a more broader garden renovation having made space from the original job. He was happy to make allowances for little details which help in the long run. Will return to him for work in the future and recommend based on both quality and competitive quotes in todays market.

Landscaping- 20 May 2026
Very disappointed with the work done on my garden. The flower bed is not straight, the grass is uneven and not level, and the slab is already coming loose. The overall finish looks poor and unprofessional. I expected a much better standard for the money paid and would not recommend this company.

Asap plastering home improvements and property maintenance
Rating: 5 out of 5
Extension Builder in Plymouth
We have been platerering since leaving school roughly 30 years, during this time we have moved on to other trades which in short covers all aspects of the building trade. We have covered many jobs of our own but mostly working for other company's running the job as our own but without earning the better money.. So now would like to run and work our own jobs as I believe having good relations with the clients as a boss and a worker will give us that professional and personal touch

Extensions- 31 Jul 2019
it all started off great and Brian came across very nice and full of knowledge. However his work was very slow and was charging me day rate, even though i asked for a quote. As he said it was an estimate the price would just keep going up. After 6 days day of working on my porch, one day longer then "estimated" he had still not finished the work. He also hadn't ordered my windows which i paid him for 2 weeks before he started work. I did talk to him about the cost of the work and how i didn't have any more money to keep paying him. I don't believe he listen to what i was saying,as 5 mins later his telling me it will be a days labour to fit to windows when he gets them. I did also email him twice which he was not happy about and also did not answer them. The work he has done is so shocking to the point we are now having to take it down and rebuild it ourselves. I have put all this in an email to him but as i said he was happy with me emailing him my issues, i did get my money back for my windows but he has not offered to put the work right.

Couldn't fault MDC construction at all. Great workmanship, always arrived when stated, communicated and asked questions throughout the job and discussed ways of completing the job to my satisfaction. At the end of the working day the area was cleaned to a high standard. The final price was actually cheaper than quoted so honesty is also a quality they have. Really good son and father team, would definitely use them again.

What to ask a Plymouth extension builder before hiring?

Before hiring an extension builder in Plymouth or extension building company in Plymouth, 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 Plymouth?

An extension builder in Plymouth 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 Plymouth 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 Plymouth?

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 Plymouth 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 Plymouth 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.
