A proper working day, with a little distance from the house. Plan a quiet, insulated workspace around your desk, daylight and the way you work. Designed and built for your Harpenden garden by our Harpenden-based team.

Our Harpenden office projects give you several useful starting points: a 4 × 3 m workspace, an office with an integrated shed, and larger rooms that combine work and leisure. For your own brief, decide whether garden storage needs a separate entrance and whether one or two people will work here. Those choices change the layout more than an extra glazed panel.
Three conversations to have before settling on the size and specification of your garden office.
Allow for the desk, chair movement, storage and any second workstation before choosing the external footprint.
Position screens alongside daylight and consider the view into the room from both your home and neighbouring gardens.
Agree socket positions, the electrical supply and a dependable connection to the house before the interior is finished.

This 4.5m x 3.5m garden room combines modern living with practical storage. Designed with a seamlessly integrated shed, it offers a versatile solution for those who want both a premium garden retreat and convenient space for bikes, tools, or seasonal items. A smart, stylish addition that balances functionality with Cedar Spaces’ signature craftsmanship.
