The reversible design means the canopy can be positioned on either side to suit your garden layout.

The price shown includes the full supply and professional installation of your Palmako Irene M++ anywhere on Mainland UK, including foundation preparation and installation and timber treatment with Smart Seal. There are no hidden costs, no separate groundworks quotes, and no surprises. What you see is what you pay.

52m² of Usable Space

The enclosed 19.0m² summer house provides a comfortable, weathertight retreat — suitable as a home office, studio, guest room, or relaxation space. The 33.2m² covered canopy is large enough for a double carport, a substantial outdoor entertaining area, a hot tub enclosure, or an outdoor kitchen with room to spare. The 44mm Nordic spruce walls, 3-6-3 double glazing throughout, and 222cm wall height make the enclosed section a genuinely four-season building.

Britmet composite slate delivers the look of natural slate with outstanding durability and a significantly longer service life. Please contact us when placing your order to arrange the upgrade.

Frequently Asked Questions

Do I need planning permission for the Palmako Irene M++?

In most cases, no. At 9.76m x 5.70m and 316cm overall height, the Irene M++ will fall within Permitted Development rights for most residential properties in England and Wales, provided it is used as an ancillary garden building, is sited within the curtilage of a dwelling house, is not forward of the principal elevation, and does not cover more than 50% of the garden area. However, at 316cm height, the Irene M++ exceeds the 300cm eaves height threshold that applies to buildings within 2 metres of a boundary — so siting will be important. The large footprint also means you should check the 50% garden coverage rule carefully. Listed buildings, conservation areas, and National Parks have different rules. We always recommend confirming with your local planning authority before ordering.

Does the price include everything — foundations, roofing, and timber treatment?

Yes. Foundation preparation and installation, roof shingles, and Smart Seal timber treatment are all included. The Britmet composite slate upgrade is available for an additional £6,000. No hidden costs, no separate groundworks quotes.

What type of foundation does the Irene M++ need?

We assess each site individually and install the most appropriate foundation as part of the price. For most residential gardens, this will be ground screws or composite pads. Where ground conditions require it, we can install a concrete slab. We will advise you on the best option during the pre-installation survey.

What extra protection do you install at foundation level?

On every installation, we fit a composite damp-proof strip along the base of the foundation beneath all pressure-treated timber. We lay a ground membrane beneath the entire building to manage moisture and suppress weed growth. And we install anti-insect and rodent mesh to prevent ingress beneath the floor — a detail that most garden building installers simply do not include. We do everything we possibly can to make every structure we install last as long as possible.

Can the canopy be used as a double carport?

Yes. The 33.2m² covered canopy is large enough to shelter two vehicles comfortably, as well as being suitable for outdoor entertaining, a hot tub enclosure, or an outdoor kitchen. Please contact us if you have specific requirements.

Can the canopy be positioned on either side?

Yes. The Irene M++ has a reversible design, meaning the canopy can be positioned on either side of the enclosed summer house to best suit your garden layout. We will confirm the preferred orientation with you before installation.

How long does installation take?

The Irene M++ is typically installed in three to four days, depending on site conditions and foundation type. We will confirm the installation schedule with you in advance.

What is Smart Seal and how long does it last?

Smart Seal is a clear, penetrating timber sealant applied to all external timber as part of the installation. It provides up to 10 years of protection. After 10 years, a single re-application coat is all that is needed.

Can I add electricity or heating?

Yes. Please contact us before placing your order to discuss your requirements.

How long does delivery take after ordering?

Typically 4 to 10 weeks from order confirmation. Please contact us if you have a specific deadline.

Do you install across the whole of the UK?

We install across Mainland UK. Island locations and certain remote areas of Scotland may be subject to additional logistics costs — please contact us before ordering.
