We had a garden room built by CG Garden Room in May. Very happy with how it turned out. Arrived exactly when they said they would and built it to our exact requirements. The whole job was finished in 4 days. Very professional and nice people to deal with.

We recently had a garden room built, and I can honestly say the whole experience was a pleasure from start to finish. The team were friendly and easy to have around from day one - polite , respectful, they turned up when they said they would each day, got straight on with the job, and worked efficiently until completed. The finish was precise, tidy and solid, it was clear they do things properly and don't cut corners. We are absolutely delighted with the result and wouldn't hesitate to recommend Conaill and his team to anyone looking for a room built by reliable, hardworking guys who know their trade and take pride in their work.

From start to finish the lads at CG Joinery were excellent to deal with! They were really helpful in discussing options, sizes, plans and models of the garden room over the phone and via Teams calls. They responded quickly to queries and made it an easy decision to travel from Galway to Newry to visit the showroom before the final design was agreed. The garden room was installed last week, after a long but very worthwhile wait - no delays, we were told when ordering it would be December, just in time for Christmas. The install team were amazing. Professional, tidy, courteous and trojan workers! Our 35m2 room was up and finished within 28hrs - built, floored, plastered with lights and heat working! They arrived at 7.30am one day and had completed the build and cleaned up by 10.30am the following day. We are more than happy with the result and feel the quality, workmanship and speed in completing the build was worth every penny. We would highly recommend CG Joinery if you're considering them.

I was lucky enough to win a competition on Instagram for a garden room with CG Joinery. It was honestly the most emotional experience I’ve ever had as this was something I have dreamt of putting in my back garden since we bought and renovated our house in March ‘23. We put a lot of money towards the win to extend our garden room and I worried this would cause hassle. Instead, it was the smoothest process ever! Conaill was always a phone call away over the months or back and fourth planning. Sarah was always at the end of every email and responded instantly. The men that came to built our dream garden room were so lovely, so easy to host and so lovely to chat about to. Every single person on the team takes their roll very seriously and you could see and hear that while they worked. They were at our door at 7:15 am and did not finish up until 7pm that night. The following day they had a 7:30 start time and the job was complete by 9:30am. I could not get over how quick they had it complete. It went to show that experience from highly skilled workers pays off. I will continue to recommend CG Joinery as in today’s world, it is very easy to get people who are looking for the money but don’t want to do the job. It makes it very hard to trust anyone anymore. But CG Joinery are whole heartedly involved and encouraging to do every job right and to the best standard! HIGHLY HIGHLY RECOMMEND! Hollie Dunlea.

Great service. There's a wait time but the room was built very quickly and to high quality. Way more economical when compared to an extension. The design your own room tool is also fab.
