After considering various shed suppliers in the area I am so pleased that I decided upon Gillies & Mackay. From my initial discussion with Kieran to installation I was very impressed. The advice given, even before I committed to buy, was streets ahead of that from other competitors and the willingness to conduct a site visit was hugely appreciated, particularly as I wanted the shed jnstalled in a relatively narrow space. Ross was very helpful at the site visit and he and his colleague installed my 12×5 shed on time and with minimal fuss. The end product is a sturdy, well built shed that I am sure will last for many years. The price was highly competitive in view of the build quality including a metal roof, guttering, shelving and thicker more durable wood as standard.

We would like to share our great experience of now being a Sheddie. From the planning to completion of our new shed we can only compliment all involved with the build. The quality of the materials used and workmanship is clearly visible. We would definitely recommend G & M for anyone requiring a quality product and friendly service.

We are very pleased with our summerhouse. We found Gillies and Mackay good to work with. Their staff were pleasant and helpful and carried out the job efficiently.

We purchased our bespoke garden room in June 2024. The quality and finish is just superb. Communication and service from start to finish from the G&M team was second to none.

The process of choosing our summerhouse, through to it being delivered and assembled could not have been smoother – and this was during/between the lockdowns of 2020/21.

2 years after it was finished we started having issues with the doors opening & closing. We hadn’t got round to painting the inside of the doors as advised, so it was our own fault. I emailed for some advice and got passed to Nicola in the aftercare team. Within 2 weeks Grant had been down and fixed our problems. We live in Edinburgh so probably a whole day out of Grants work schedule.

Following the horrendous rain this spring we found that we could not open our doors at all (to our shame we still had not got round to painting them!) Even at that John scheduled a visit to fix them again. Fortunately they shrunk just before the visit. Suffice to say that they will be getting painted during this dry weather!

We’ve had a similar level of service from another independent company who fitted windows & bi fold doors for us 6 years after purchase. It really pays in the long run to use “local” independent companies where possible in our experience.

Excellent quality built sheds (I bought two a couple of years apart) one for gardening tools, push bike etc while the other a slightly larger one to use as a hobby workshop. I prepared the ground bases my self (all part of the fun of delivering the project, hard work though), and upon arrival the shed builders refined the finished level to ensure accurate setting. The sheds came with a coat of paint already on them but I gave them both a second coat as recommended by G&M to ensure warranty conditions were met and longevity. I an more than pleased with the build and quality of my sheds and I am pretty sure they are both going to out live me. The very presence of my sheds (hobby shed in particular) incite me to get out of the house and involve myself in my gardening and carpentry hobby. Could not be happier with my purchases and service I received from G&M. I am now toying with idea of creating a canopy between them so as to enable the space between them to also be used during inclement weather.

We are so happy with our garden room, we bought in April this year, it is our little sanctuary where we can relax and chill out in peace. Gillies & Mackay have been brilliant the build work is professionally done, the electrical people they put you in touch with where also great. I would encourage everyone who were thinking of having a summerhouse to have a chat with Gillies & Mackay you won’t regret it, also the garden room is very versatile it can also be an office or spare room whatever you need it for, money well spent we feel. Thank you Gillies & Mackay!

It is over 10 years since I purchased a shed from G&M Ltd. Since then I have been involved in helping friends and relatives in their choice of sheds and shelters with mixed results. Everything has simply confirmed that I made the best choice in buying from G&M. It has moved house with me, been adapted internally and at every point the quality of workmanship has shone through. Although I live a fair distance from G&M, it is still the place I look to for quality and sheer workmanship.

We have had a very positive experience with Gillies and Mackay. The salesmen were very knowledgeable and friendly. They took time to listen and address any questions we had without pressing us into a sale. We have one of the new radiata garden rooms and the team took care to build it to a high standard without, as far as we can tell, without cutting any corners. We are pleased with the professionalism of the Gillies and Mackay team and our finished garden room.
