Introduction to JML

JML SIPs, JML Garden Rooms, JML Contracts and JML Gabions make up the JML group of companies. The four businesses whilst operating in slightly different markets and with different customers, all ensure a high quality service and project delivery with the same values and goals.

The JML Story

Founded by husband-and-wife team, John and Katie Langley, JML is more than just a business it’s a shared dream, shaped by family values, hard work and a belief for success.

John developed a passion for the construction industry from learning the ropes in his father’s business and studying Construction Management at Heriot- Watt University. He had a vision to build a business that was sustainable, forward thinking and run by talented and dedicated people, with the same passion and core values.

Katie’s background is in marketing, bringing creative thinking and problem-solving skills along with a strong work ethic from growing up on the family farm, with the same vision for success and shared core values. 

Starting the business was not easy with many long days and late nights at the outset. Now nearly 20 years later the company is thriving and has grown to support 60 employees over 4 divisions – JML SIPs, JML Garden Rooms, JML Contracts and JML Gabions. The business has stayed to true to its values, created opportunities for others and shown testament to what’s possible when hard work, ambition and drive come together.

With big plans for the future, John and Katie want to create an inspiring local workspace to bring together like-minded, interconnected businesses, all sharing a creative and collaborative environment.
