• Unique Garden Rooms in Cornwall, Year-Round Spaces for Work, Wellness & Living

Whether you're juggling work-from-home life, craving a space for your creative practice, or dreaming of a guest suite that doesn't take over the house, a garden room might be the answer.

Beautifully designed, fully insulated, and tailored to your specification, our garden rooms in Cornwall switch underused outdoor areas into high-functioning, all-season spaces.

Unlike makeshift sheds or chilly garage conversions, these are purpose-built structures, designed for comfort, style, and year-round living. Think: a light-filled office that's free from distractions, a yoga studio that opens to the morning sun, or a cosy space where friends can stay without sharing your hallway bathroom.

What Is a Garden Room?

A modern garden room isn't just a glorified outbuilding or shed - it's a fully insulated, wired, and professionally finished space built to the same standards as a home extension. The key difference? You get the extra room without the red tape, cost, or disruption of a full-scale home renovation.

Common uses include:

  • Home office, gym, or creative studio
  • Guest suite or occasional annex
  • Therapy or consulting space for client meetings
  • Teen den, hobby room, or quiet retreat
  • Garden bar, cinema room, or wellness pod

All designed to blend with your property's aesthetic - whether coastal contemporary, countryside rustic, or something uniquely yours.

Solving the "Not Enough Space" Problem

For many Cornwall-based homeowners, the struggle for space is real. Especially in character properties or tightly plotted homes. Extensions aren't always practical, and lofts or garages often fall short of what's needed.

A garden room steps in as a practical, elegant solution:

For remote workers: Separate your workspace from home life without a commute

For families: Add breathing room for teens, hobbies, or guests

For professionals: Welcome clients into a private, professional setting

For hosts: Offer a boutique-style stay for visitors or Airbnb guests

For wellbeing: Create a calming, dedicated space to focus on health or creativity
