Additional floating space beside a narrowboat
The big idea

Keep the Boat. Add the Room You're Missing.

Your boat may still be exactly where you want to live, work or spend your free time. It just might not have enough room anymore.

Instead of replacing it with something bigger, Rosethorn can create a separate floating space designed around what you need more room for.

That could be somewhere to work, somewhere to store, somewhere to create, somewhere for guests, or simply somewhere to switch off.

What do you need more space for?

One Floating Space. Almost Endless Possibilities.

Creative and lifestyle space

Create on the Water

Your extra space does not have to solve a problem. Sometimes it can create an opportunity.

A place to paint. A place to write. A place to make. A place to read. A place to work uninterrupted. Or simply somewhere to sit beside the water and close the door.

Your boat is where you live. Your floating space can be where you create.
