I originally contacted Joe from Orama to fit a new kitchen for me. When he came to give me a quote, I hadn't yet chosen what I wanted. He really took the time to make several recommendations and so I decided to go ahead with him to design my kitchen fully and fit it. The team were so easy to work with and most importantly respectful in my home! Their attention to detail is second to none. He really understood the style I liked in one conversation. The finish is flawless. I highly recommend them!!

I am very pleased with the work Josh and his team did in building my rear extension. They were a friendly and hard working bunch and very respectful of my space. Josh did a great job in project managing the work and making sure things were progressing as planned. Any snagging items were dealt with promptly. I would hire them again if required and recommend them to anyone who wanted to have building work done.

Extensions- 22 May 2019
Jacob was very accommodating and flexible. His team were great and he completed the work nicely. There was some splatter from the cementing on to my neighbour's wall. He tried to clean it off but it wouldn't all come off. Therefore, he went out and bought some paint and repainted their wall. I would get him back for more work without hesitation. When looking for a builder - they have to be honest, work hard and to an excellent quality without cutting corners. They should be responsible to ensure neighbours property isn't damaged and provide consultancy as what we want and want is realistic can differ significantly! - and if any issues rectify them once the job is complete and of course provide good after sales. I have used several builders over the years - very few tick all of the above boxes. Jacob certainly does.

I asked Daniel to check and price some pebble dashing job. Daniel was fair in his pricing. He was on time in commencing the work as we had agreed. He never left the site until the job was completed within a few days, hence causing least interruptions. I do recommend him and I intend to ask him to carry out works in future.
