Outstanding building firm!

5
We engaged Roundhouse to undertake a challenging conversion which they were more than happy to take on.

We have a 400 year old farmhouse with an attached stone barn. We wanted to convert this to a large single room with vaulted ceiling and large bifold doors opening on the garden. It was important for us to respect the history of the building by featuring the original stonework.

Mike and the team at Roundhouse along with Martyn the architect, sensitively approached the conversion by staying true to the character of the building. They used reclaimed materials from a local reclamation yard where possible and re-pointed the original stonework, which is truly stunning.

Not only was the quality of their work impeccable, they were genuinely a pleasure to work with. The team were punctual, efficient and were extremely respectful of the impact the work had on our family and our neighbours. We hardly noticed them (in a good way!). I would recommend them for all manner of building work.

House internal renovation and new extension

5
A fantastic internal renovation and extension build by Mike and his team. They turned our house around to deliver exactly what we wanted. Thanks to Mike for his advice and experience in guiding us as to what would work/look good.
A lovely polite team who were on site every day despite it being through a horrendous winter (very cold and wet!)
Thoroughly recommend and we’ll use them in the future (though maybe during the summer next time!)

Exceptional work by a fantastic team!

5
If we could give more than 5 starts we definitely would! We chose Roundhouse builders to complete a rear single story extension & patio area and we are so pleased we did. Mike and the team were fantastic from the very first day. From quote, to planning, to final build the process has been excellent. The team worked through all weathers to maintain the given timescales and managed all aspects of the build meticulously.

A very professional team providing an outstanding quality of work and exceptional attention to detail. We would highly recommend Roundhouse builders to anyone looking for a very reliable building company. We are so pleased with the final project, it has far exceeded our expectations. Thank you Mike & team Roundhouse, we will miss having you around! There is always tea & cake on offer if you are passing :)

Pontypridd kitchen/diner extension with Patio

5
Mike and his team are exceptional. They have been brilliant at building our dream kitchen/dinner extension keeping to the quotes and time scales cited while working relentlessly shaking off the worst of the 2022/23 bitter Welsh winter. They were very careful in minimising any mess and disruption especially over the Christmas period.

During the build the team uncovered multiple pre-existing problems and were able to solve these unforeseen problems within the original budget using the necessary specialists, ensuring no corners were cut. RCT building control also commended on how it was good to see such professional team at work ensuring that all modern standards were upheld.

I will miss having the team around as it is great to see people who enjoy their work and take pride putting in that extra effort and quality.

Quality is the key word with Roundhouse Builders. So, if you have a project that needs doing, even if you must wait a bit, choose Roundhouse Builders!

First class

5
We’re delighted we chose Roundhouse Builders for our house extension. From the outset, Mike listened to what we had in mind and came back with a well thought-out plan. As the project progressed, his experience and proactive suggestions were invaluable to us as we navigated our first building project of this kind.

The whole team was a pleasure to have around. Everyone was polite & helpful (and great with kids and dogs!). They were reliable and worked very hard to high professional standards. It was reassuring to us to see them taking pride in delivering quality results.

The project was completed on time and on budget. Huge thanks to everyone on the team for your skill and dedication, which have meant that the final result has comfortably exceeded our expectations. We wouldn’t hesitate to recommend Roundhouse Builders.
