North Down has some of the most generous suburban gardens in the province. In Bangor, Helen’s Bay and Holywood that usually means depth to work with, mature planting to design around, and neighbours close enough that where you put the building matters.

Older, settled gardens bring their own considerations. Mature trees cast shade for half the day and drop leaves onto flat roofs. Boundary walls and hedges affect where light falls. Existing patios and drain runs limit where a base can go. We work all of that out on site before proposing a size or position, because moving a garden room afterwards is not an option.
Plenty of Bangor properties have a long garden and a narrow side passage, which is the combination that catches people out. We measure the access route at survey and tell you honestly whether materials will go through, whether a crane lift over the roof is needed, or whether a slimmer build is the sensible answer. Better to hear that before you commit than on the morning of installation.
We consist of a group of highly qualified tradesmen and are now very proud specialists in insulated garden rooms, serving Bangor, Newtownards and right across North Down.
We aim to have our insulated garden buildings completed within 3–5 days to minimise disruption for you.
Confirm your booking with a deposit, make a part-payment on day one of installation, then settle the balance on completion day. *Finance options now available

Garden offices dominate, particularly for people commuting into Belfast who now work from home part of the week. Gyms and studios follow. Larger garden houses come up more often here than elsewhere because the gardens allow it. We also handle extensions and conservatory roof conversions across the area.
