CG Garden Rooms

Bespoke Garden Rooms

Made-to-Measure Garden Rooms, Not Catalogue Sizes

A bespoke garden room is drawn around your garden rather than chosen from a size list. That means you are not paying for space you cannot use, and you are not forced into an awkward compromise because a standard unit is 300mm too wide. We design, build and install across Northern Ireland and Ireland.

Reliable & Qualified Experts

A team of qualified tradesmen specialising in insulated garden rooms, working across Northern Ireland and the Republic.

Quick Turnaround

We aim to have our insulated garden buildings completed within 3-5 days to minimise disruption for you.

Competitive & Flexible Prices

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

Why Bespoke Usually Fits Better

Most gardens are not rectangles with clear access. Boundaries run at angles, drains and manholes sit in inconvenient places, and the best light rarely faces the most obvious wall. Designing to the actual plot lets us place the door and glazing where they work instead of where a standard unit dictates.

What You Choose

Footprint and internal layout, door type and position, glazing size and placement, cladding in composite or timber, internal finish, socket and lighting positions, and heating. We agree all of it with you in writing before the build begins.

Design and Survey Process

We start with a free quotation on request, then survey the site properly — access, levels, boundaries and services. From that we confirm the specification and issue a fixed written quotation. Bookings are confirmed with a 10% deposit, with 50% collected on day one of installation and 40% on completion.

Just want to say thanks to one of your lorry drivers. I didn't manage to get his name. I got stuck in a hedge this morning (just outside of Banbridge) and your driver along with a few other lads, got me hooked up and towed me out of the hedge. I am extremely grateful to him. I just want to say thanks again, if you could pass this on to your drivers. Thanks.

We recently had a garden room built by CG Garden Rooms and I honestly couldn't recommend them highly enough. From the first conversation right through to completion, the communication was excellent. Every question was answered quickly, timelines were clear, and the whole team was an absolute pleasure to deal with. Nothing was ever a problem. One thing that really stood out was that all materials had to be brought through our house to access the garden. I was quite concerned about this beforehand, but the team took such care and made the entire process completely seamless. They were respectful, tidy, organised and treated our home as if it were their own. The quality of workmanship is outstanding. The attention to detail, finish and overall build quality exceeded our expectations. It's clear that pride is taken in every aspect of the work. What can sometimes be a stressful project was made easy from start to finish thanks to a professional, hardworking and genuinely friendly team. We're absolutely delighted with the finished garden room and have already had so many compliments on it. If you're considering a garden room, I would have no hesitation in recommending CG Garden Rooms. Thanks again to all the team for such a fantastic job. Tara McHugh

Absolutely fantastic experience from start to finish! We recently had a garden room, shed, and hot tub room built by CG Joinery and couldn’t be happier with the results. The whole process was incredibly smooth — the team completed everything quickly without any fuss or delays, which was a huge relief. What really stood out was the service. Conaill, Michael and Sarah we dealt with was friendly, professional, and genuinely helpful at every stage. They kept us informed, answered all our questions patiently, and clearly took pride in their work. You could tell they cared about getting every detail right. The finished garden room looks brilliant and has already become one of our favourite spaces. The shed is solid, practical, and exactly what we needed for storage, while the hot tub room is a real standout — beautifully finished and the perfect place to relax. Highly recommended if you’re looking for quality workmanship delivered with real care and efficiency. We wouldn’t hesitate to use them again!

We couldn’t be happier with our new garden room from CG Joinery. From the very first meeting right through to completion, the entire team has been fantastic to deal with. Their workmanship, attention to detail and professionalism have been outstanding. Nothing was ever too much trouble. The quality of the finish has exceeded our expectations, and it’s clear they take enormous pride in their work. The team were punctual, friendly, hardworking and left everything clean and tidy. It’s rare to find a company that delivers exactly what they promise, but CG Joinery certainly did. If you’re thinking of adding a garden room to your home, I wouldn’t hesitate to recommend CG Joinery. A first-class company delivering a first-class product. Thank you to everyone involved—we absolutely love our new space!

I cannot speak highly enough about the CG Joinery team. Everyone from the office to the guys who come and build are a pleasure to deal with and go above and beyond to advise and support. You won’t go wrong with them and you’ll have a gorgeous room at the end!

Bespoke Builds for Difficult Plots

Sloping ground, narrow side access, mature trees and awkward boundary angles are the situations where a standard unit fails. These are the jobs bespoke construction exists for, and we will tell you at survey what the site genuinely allows rather than promising and improvising later.

Cladding and Exterior Finish

Composite cladding holds colour and needs almost no upkeep. Timber gives a softer, more traditional appearance and wants periodic treatment. We supply both, plus porcelain paving and trims, so the finished area is coherent rather than assembled from three suppliers.

Does Bespoke Cost More?

Not automatically. Because the room is sized to your garden you are not buying unusable floor area, which often offsets the design work. Cost rises where the specification rises — larger glazing, higher insulation, more complex groundworks — not simply because it is made to measure.

Bespoke Garden Offices and Studios

Where the room has a defined job, bespoke pays for itself. An office gets sockets at the desk and glazing that avoids screen glare. A studio gets the light orientation right. A treatment room gets the drainage considered before rather than after.

Insulation and Year-Round Use

Insulated walls, floor and roof as standard, with glazing specified to match. A bespoke room that is cold in winter has failed regardless of how well it fits, so this is not an upgrade we treat as optional.

Where We Build

Throughout Northern Ireland and the Republic from our base at Mayobridge, Newry — Belfast, Lisburn, Derry, Newry and surrounding counties, and across the border through Louth, Dublin, Meath and beyond.

Frequently Asked Questions

The room is designed to your plot and your use, rather than selected from fixed sizes. Footprint, layout, door and glazing positions, cladding, internal finish and electrics are all agreed with you before the build starts.

Not necessarily. You are not paying for floor area you cannot use, which often offsets the design work. Price rises with specification, not with the word bespoke.
Usually yes – those are exactly the sites bespoke construction exists for. We assess levels, access and services at survey and tell you what the plot genuinely allows.

Design and survey are quick; the lead time depends on specification and current workload, and is confirmed in writing at the point of order. Installation itself is normally measured in days once the base is ready.
