At Cedar Spaces, we build bespoke garden rooms that are design-led, tailored to you, and built to last. With a choice of premium finishes — from natural timbers to modern composites — your space will perfectly reflect your lifestyle and enhance your home.
Bespoke garden rooms crafted with precision and built to last across Hertfordshire and beyond.
At Cedar Spaces, every project begins with your vision. We design and build bespoke garden rooms that combine style, functionality, and durability — creating modern spaces that are as practical as they are beautiful.
Working across Hertfordshire and neighbouring counties, our experienced team manages every stage of the build in house, ensuring a seamless process and exceptional craftsmanship with 5 star customer care. Each room is fully insulated for year-round comfort and finished with electrics, plastered walls, flooring, lighting, and premium glazing. With a choice of natural timber or modern composite cladding, your Cedar Space becomes a lasting extension of your home.
My name is Brian O’Connell, and Cedar Spaces began in 2018 when I built my own garden room. With young children at home, it quickly became a space where I could focus on work, fitness, and family life in balance. Experiencing that transformation first-hand inspired me to help others do the same. Today, I combine my background in engineering and financial planning with a passion for design to create bespoke garden rooms that bring everyday life more space, comfort, and style.
Add versatile, high-quality space to your property without the hassle of major building works. In most cases, no planning permission is required.
Every garden room is unique — tailored to your lifestyle and your needs, whether for work, wellness, or relaxation. We work with you from concept to completion to create the perfect design.
Fully insulated and heated, your garden room provides a functional living space in every season — cool in summer, warm in winter.
From home offices to gyms, music rooms to guest spaces, your Cedar Space adapts to how you want to live — while using eco-friendly materials and smart design.
Finished in your choice of natural timbers or modern composites, our garden rooms are built to last with minimal upkeep, retaining their beauty year after year.
We manage every detail in-house and keep you informed at each stage. Every building comes with a 10 year structural warranty, giving you complete peace of mind.

Our buildings are affordable investments to your home which will not only add extra valuable space but will also add value to the price of your home if you sell in the future.
