Newry is where we are based. Our workshop and showroom are at 7 Ryan Rd, Mayobridge, just outside the city, so a Newry garden room is a local job for us in the fullest sense — we are not travelling in from another county and adding it to the bill.

CG Joinery is a family-run joinery business established in 2009. Being based at Mayobridge means short travel times, quick site visits before we quote, and a showroom you can visit without making a day of it. If something needs attention after installation, we are ten minutes away rather than a hundred miles.
Newry sits in a valley between the Mournes and the Cooley hills, which means exposed sites, wind and a fair amount of rain. That is precisely why insulation and cladding specification matter here more than in a sheltered suburb. We build for local conditions because we live in them — insulated walls, floor and roof, and composite cladding where exposure justifies it.
A team of qualified tradesmen specialising in insulated garden rooms, working across Newry, South Down and South Armagh.
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

Home offices, garden gyms, studios and treatment rooms, garden pods for smaller plots, single-storey extensions and conservatory roof conversions. We also supply the composite cladding and porcelain paving to finish the surrounding area, so the whole job comes from one place.

From our Mayobridge base we cover Newry city, Warrenpoint, Rostrevor, Hilltown, Rathfriland, Banbridge and across South Down and South Armagh. Being close to the border we work on both sides routinely, so a job in Louth or Dundalk is no more complicated for us than one in Newry itself.
Our workshop and showroom are at 7 Ryan Rd, Mayobridge, just outside Newry (BT34 2HZ). Being local means quick site visits before we quote and a team that’s around ten minutes away if anything needs attention after installation.
Yes. Our Mayobridge showroom has several full-size garden rooms in different sizes and finishes. Visits are by appointment, Monday to Friday 8am–4:30pm and Saturday 9am–2pm. Book online or call us to arrange a time.
Garden rooms start from €15,000. The price depends on size, glazing, insulation and heating specification and site access. We give you a written, itemised quote after a free site visit, and nothing is added once work has started.
Usually not. In Northern Ireland a single-storey garden room behind the house, under 4 m high (2.5 m within 2 m of a boundary) and covering no more than half the garden is normally permitted development. The Mournes and Ring of Gullion are Areas of Outstanding Natural Beauty, so we check your location at survey.
Yes. Newry sits between the Mournes and the Cooley hills, so many sites are windy and wet. We build for those conditions with insulated walls, floor and roof, careful sealing, and composite cladding where the exposure justifies it.
