We create garden rooms that make your dreams a reality.

We Offer Bespoke Garden Living

Everyone’s vision for their personal garden room is different. That’s because every Crannog customer is different. We offer you Choices to customise and make your garden room perfect for you.

It starts with simple things, like different external cladding, internal finishes, window placement to suit garden orientation all the way to decking areas standalone solar power/battery solutions, business-grade internet connectivity.

For those who wish to take on some DIY or employ their own installation resource, we have a supply only option where your Crannog is assembled off-site and delivered complete to your home.

We Look After You

Our company has been in the renewables business for over 20 years and has extensive construction, engineering resource to bring innovation and allow us to stand behind our product.

Our aim is to provide you with the best purchase experience and aftersales support that comes from knowing our customers and what they deserve.

We take a fresh approach to assembly and delivery to reduce the time from order to delivery. We used modern construction methods which allows us to preassemble walls, floors and roofs off-site to minimise time on site.

Our Environmental Performance & Social Commitment

Carbon Emissions

The residential sector was responsible for 10.9% of total greenhouse gas emissions in 2019 according to a government agency, EPA. We have invested a considerable amount of time and resources to produce one of the most energy-efficient, highly insulated, environmentally friendly garden buildings available in Ireland today. Every Crannog Garden Room is constructed with 147mm thick structurally insulated panels for walls, floor and roof. This provides near passive levels of energy conservation and very warm, low running cost space for year-round use. Warmed by a solar gain from the low winter sun, it provides a comfortable year-round living environment.

Environmental Impact

Following and independent assessment by an accredited energy assessor our garden structures achieved a very high rating for both environmental impact and energy conservation. We are committed to reducing our environmental footprint where possible: we use only timber with FSC certification, which ensures products come from responsibly managed forests. We employ locally and use local suppliers where possible.
