Are you looking to add some additional space to your property? Whether you have your heart set on a home gym, a bespoke granny annexe or an office for you to work from home, we’ll be able to help. With almost 20 years of experience in building with SIP panels and timber frames buildings using your ideas and adding our professional advice we can transform imagination into reality.

The installing of an TRJ Construction Ltd garden room is fast - simply choose your preferred design and finishes, and your extra living space can be complete and ready for use in as little as 3-6 weeks depending on the size and complexity of the project.
Using only the highest-quality materials, our products are built to last, and constructed for UK weather conditions. Our outdoor rooms are UK-made, fully insulated and come with a 10 year structural guarantee.

All of our bespoke garden rooms are made from Structural Insulated Panels – or SIP for short. What is SIP? Well, they are wooden panels with a foam core, which provide incredible insulation. They are so much warmer than brick walls, allowing you to enjoy your new studio all year round. SIP panels are also stronger and more durable than any other kind of wall or panel.
