About Oakspan

Founder-led. Purpose-built. No sales pitch.

At Oakspan, we design and build custom garden rooms that truly fit your life—from insulated garden offices to full-scale annexes and everything in between.


But what really sets us apart? You don’t talk to a sales team. You talk to me, Kevin—the founder, builder, and hands-on lead behind every project.


With over 15 years of experience in construction and design, I started Oakspan because I saw a better way to do things. Too often, people were being sold quick-fix buildings that didn’t suit their space, didn’t last, or didn’t work for how they actually lived. I wanted to change that.


So I built a business around doing things properly—with real materials, real craftsmanship, and a real person guiding every step.

What we do and why it works.

We create insulated, climate-controlled garden buildings that look good, feel good, and work year-round. Whether you're building a quiet workspace, a family hangout, or a self-contained annexe, every project starts the same way: with a conversation—not a pitch.


We’ll talk about:


  • Your lifestyle and layout needs

  • Your site, space, and budget

  • What makes sense (and what doesn’t)

  • How to get the most value long-term

There are no templates. No pressure. Just honest advice and a plan that actually fits.

My Approach

“If I wouldn’t build it for myself, I won’t build it for you.”


That’s the simple rule I live by. When you work with Oakspan, you get my full attention. I’ll personally scope, quote, and oversee your build—start to finish.


I don’t believe in cutting corners. I believe in:


  • Clear communication

  • Smart design choices

  • Comfort that lasts all year

  • And being someone you can actually get on the phone
