Glevum Bespoke Workshops

A Secure, Contemporary Workshop with a 10 Year Structural Guarantee

The Glevum Workshop is built using the SIPs system that we manufacture at our workshop using the highest quality materials. This cost-effective, sustainable method of construction delivers strength, versatility and longevity, ensuring a workshop that’s built to last.

Panel weight and size have been carefully designed to make manual handling and assembly easy, even in areas where the access is tight. The prefabricated panels are manufactured using FSC certified and graded timber and high quality grey EPS insulation to exacting standards.

As with all of our workshops, it has high levels of air tightness and thermal performance, requires minimal assembly time on site, achieves reduced waste and ensures a high-quality finish that will continue to look eye-catching year after year.

Luxury Garden Building Payment Terms

Payment Terms

We offer structured terms to support you with the purchase of your garden room, with a four stage payment plan as follows:

Stage 1: £1,000 deposit to secure your order, built slot and installation date.

Stage 2: 35% of the total room cost due 4 weeks before your agreed installation date (this amount includes the £1,000 deposit already paid).

Stage 3: 55% of the total room cost will be due for payment once the room is on site and being installed, usually on Day 3 of the installation.

Stage 4: 10% of the total room cost is payable when the room has been fully completed. This is usually 4 weeks following completion of the installation, giving time to allow your room to settle and any post-installation issues to be addressed. When the final payment has been received, we will issue all the relevant certification and guarantees.

Ground Screws For Garden Room


Typically, we would expect you to need one of the three types of foundation for your garden room: pad, ground screws or existing/new concrete base.

Ground Screws

Galvanised pins that screw into the ground create a strong level platform for your garden room, offering a number of benefits:

  • Speed: ready to use, so same day installation
  • Strength: create a strong, solid base
  • Levelling: ideal for use on uneven ground
  • Unintrusive: causing less impact to tree roots and ground
  • Cost: less having to be spent on materials, time and labour

Pad Foundation:

Pad foundations are used where rocky conditions are found. We remove the topsoil, dig a hole out of the hard ground and back fill with a quick dry concrete to form a pad foundation. Our adjustable feet are then used to level off the base of the room.

Existing Hard Standing:

When a room is installed onto existing hard standing, our adjustable pads are used to level the base of the room.

Everyone, from the crew who did the initial build to the plasterer, electrician and painting team, were absolutely amazing

I wanted to take the opportunity to thank you and all the team who installed our garden office at the end of November. I was delighted that EVERYONE from the crew who did the initial build (in just two days!), to the plasterer (a true "old school " artisan!) and the electrician and painting team were absolutely amazing, VERY professional, cheerful, quick and left the site very tidy indeed! I really appreciated their flexibility and attention to detail too.
