Meet Brian the boss of Cedar Spaces

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.

Once contracts are signed a 30% deposit is then required to secure your project and allow us to begin ordering materials.

We aim to have your garden room completed and ready for you to enjoy within 15 days. Rooms with services that require connections to mains plumbing etc. may take longer. Smaller rooms can be completed within 7 days.

Our buildings are built on poured concrete foundations or ground screws. Options will be discussed with you during our initial site visit.

Under new regulations that came into effect 1st October 2008 Garden Room’s (outbuildings) are considered to be permitted development, not requiring planning permission, subject to a few limits and conditions. For more detailed information see – http://www.planningportal.gov.uk/permission/commonprojects/outbuildings. It is the ultimate responsibility of the home/land owner to ensure their Cedar Room meets Planning & Building Regulations, although we are on hand to give advice and support.

Each project we build is unique and it is therefore difficult to present a set menu cost for your build. As an indicative figure our garden room prices start from £1,250 per square meter.

Please note that our buildings are high specification garden rooms and are built with the quality and construction methods of a new home, therefore the price of a Cedar Space should be compared with the price and inconvenience of an extension rather than the price of a shed. 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.
