About Oakspan

The Anti-Salesman Approach to Architecture.

Most garden room companies are sales machines that happen to build sheds. Oakspan is a workshop that happens to build sanctuaries. Meet Kevin Tomlinson—the man who personally guarantees your project.


"I spent 15 years in construction watching the same cycle: A slick salesperson promises the world, takes a deposit, and then disappears. They hand the project to sub-contractors who have never met the client, using 'flat-pack' materials that aren't built for a Scottish winter.



I started Oakspan to kill that cycle.

When you hire Oakspan, you aren’t just buying a garden room; you’re hiring my 15 years of site experience. You’re getting a structure built with the same structural integrity as a residential home, overseen by the person whose name is on the guarantee."

What we do and why it works.

No Middlemen. No Chinese Whispers. In the construction world, "communication" is usually the first thing to break. I’ve eliminated that point of failure:


  • Direct Access: You have my personal mobile number.


  • Master-Grade Oversight: I don't just "manage" the project; I am on-site ensuring the vapor barriers, insulation, and finishes meet my personal standard.


  • The 'If I wouldn’t live in it, I won’t build it' Rule: If a design choice compromises the longevity of your building, I’ll tell you—even if it costs me the sale.

The 6-Point "Peace of Mind" Checklist

1. The Fixed-Price Lock: Once we agree on a quote, that is the number. No "unexpected material costs" halfway through the build.

2 All-Season Engineering: We use LG climate control and high-spec Kingspan insulation as standard. These aren't summer houses; they are 365-day living spaces.

3. The 5-14-Day Sprint: Our specialised team is trained for speed without sacrificing precision. Most rooms are ready for furniture within 5 days.

4. 10-Year Structural Integrity: Backed by my reputation and our comprehensive guarantee.

5.'The "Permitted Development" Guarantee: We design our rooms to fall strictly within UK planning laws (usually under 2.5m height). We handle the compliance so you never have a headache with the local council.

6. Zero-Maintenance Exteriors: We use premium slatted composite cladding that looks like natural wood but never requires sanding, staining, or oiling. It’s built to withstand the Scottish climate without you lifting a finger.


"I know a garden room is a significant investment. It’s a place where you’ll build a business, reach fitness goals, or house your family. It deserves more than a 'sales pitch.' It deserves a master craftsman.


Let's talk about your project—honestly."
