Our expert and dedicated team is proud to offer innovative, sustainable and energy-efficient solutions to private and commercial clients across the UK.
With our own in-house SIPs designers, engineers, groundworks team, installation team and SIP processing factory we are committed to quality and the delivery of excellent customer service – every time.

We have been fortunate to be involved in some exciting SIPs projects over the years, including hosting Kevin McCloud and the Grand Design TV crew at our factory in Perthshire in 2017, and supplying and erecting the SIPs kit for the RIAS House of the Year in 2018.
"We are delighted with our JML Joro house kit. The entire process of arranging the build has been easy, and there has been clarity at every stage. Everyone who has been involved in the build has been professional, friendly and very prompt in offering advice and support. The kit delivery and erection was handled quickly and efficiently. The quality of the product is excellent, and we love the fresh, contemporary design. We highly recommend this company."
Thompson, Nairn
"JML had their own in-house Architect and this got the project moving and on budget. JML built and erected the SIPs frame of a large extension to the rear of our property. They also did the roofing and a front porch, together with the cladding. Once involved, the project went very smoothly and I wish we had involved them right from the start. The guys on site were very good, and I can't fault the service in any way. I can't recommend this company enough and would not hesitate to recommend them or use them again. They are not the cheapest, but you do get very high quality at a reasonable price, and the project represented great value compared to other quotes we had. The work was also all done to the correct timescale, which is rare in this industry".
Logan, St Andrews
"A good team that hold many years of experience in the construction of new tech construction methods. Project was on time and the team that came down from Scotland were polite and hard working".
Ian Dilks, Norwich
"First class service from Commercial Manager, Derek McIntyre, at all stages of the project. Once on site, Gavin Brock and his installation team were skilled and highly efficient. JML SIPs are a great team and know their product."
G. Smith, Strathaven
"For you and your team to hit your estimated build costs at every turn and to do it before deadline was a real credit to your organisation and efficiency and a massive relief to ourselves. We could not have asked for better building contractors. John was so patient and tolerant of my crazy plans and last minute alterations to the house."
Mr & Mrs Wilson, Tree Cottage, Killearn
"We are extremely pleased with the professional service provided by JML SIPs. Not only is the work to a high standard but also the positive and client specific approach was exceptional throughout."

Ian Reynolds, Killikrankie
"JML SIPs were very professional and conscientious throughout all the stages of the construction of this high specification property. Their attention to detail, responsiveness and service provision were first class."
Douglas Sheasby, Dunblane
"We are delighted with the high standard of renovation and extension work recently carried out by JML SIPs. John and Robin proved invaluable with help and advice as the project progressed and all the direct tradesmen employed by them were helpful, courteous and efficient. No problem was too big or small and they were very flexible with all arrangements."
Bob Lindsay, Dunkeld
"The team were courteous and hard working, arriving promptly on site every day. The site was also kept very tidy with cut blocks and slates stacked for use before any new materials were cut. Every comment from the local community about the build has been positive and I am happy to pass on the recommendation to anyone considering building a house."
Gordon Motion, Stirlingshire
"JML SIPs provided a first class service in building our four-bedroom house in Moray. We were highly impressed with the design consultant who listened to our requests and with us decided on the house that would meet all our needs. We were supported through the whole building process and felt that we were listened to. It is not too much to say that we enjoyed the journey. During the build the workmen were well mannered and hard working. They were clearly skilled craftsmen and confident and efficient in their work. The manager and designer were attentive to our request for change and creative in managing any problems that arose. When we contacted the office manager and reception staff they were friendly and very helpful. We had an excellent experience with JML SIPs and would certainly use them again."
