How Nestive Began

Nestive was born from our shared passion for creating beautiful, lasting spaces using natural materials and traditional craftsmanship. During the first lockdown, we saw how much people needed more room to live, work, and unwind — and that’s when we set out to design and build bespoke garden rooms that feel personal, sustainable, and built to last.

Every Nestive garden room is crafted by our small team — Carl, Gerli, and Sten and our trusted craftspeople — combining a lifelong love of woodwork, a deep connection to nature, and a shared passion for creating spaces designed around you.

Garden Rooms Designed for Living

We believe your garden room should enhance your daily life — whether you’re working, relaxing, or spending time with family. That’s why we focus on thoughtful design, natural materials, and craftsmanship that stands the test of time.

Stories From Nestive Clients

"I was fed up working at the kitchen table and really needed my own space. Nestive were great — they listened to what I wanted, kept me updated throughout, and the whole thing was done with zero hassle. The room looks amazing and the quality is spot on. I honestly don’t know how I managed without it."

— Sarah T., Vale of Glamorgan

"I didn’t think a container could look this good! The team turned it into a really lovely, cosy space where I can do yoga and switch off. I love that it’s upcycled too. The whole process was easy — friendly, no pushy sales, just clear advice and great communication."

— Mark L., Swansea

"We wanted somewhere to hang out as a family without extending the house. Nestive made it so simple — no dramas, no delays, and they were a pleasure to deal with. The build is solid and it looks brilliant. We’re out here all the time now."

— Emma & Tom R., Mid Wales
