Fully Installed Palmako Irene XL Summer House Log Cabin with Porch | Garden Room | Home Office — Professionally Installed Across Mainland UK

The Palmako Irene XL is a large, light-filled summer house log cabin that brings a genuine sense of space and openness to any garden. With 21.9m² of internal floor space, a 5.2m² covered porch that can be positioned on either side of the building to suit your garden layout, and a sweeping 239cm wide double door that connects the interior to the outdoors, this is a cabin that is designed to be lived in — not just looked at.

Whether you are looking for a premium summer house, a garden room, a home office log cabin, guest accommodation, or a year-round outdoor retreat, the Irene XL has the scale, the insulation, and the quality of construction to deliver on every level.

The price shown includes the full supply and professional installation of your Palmako Irene XL 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.

Open to the Garden, Closed to the Weather

The 239cm wide double door — one of the widest in the Palmako range — opens the entire front elevation to the garden. The 5.2m² covered porch, positioned to whichever side best suits your garden, creates a sheltered transition space. The 44mm log walls, double-glazed glass, and rubber-sealed frames keep the interior warm, quiet, and draught-free when the weather turns.

Roofing Upgrades

We will not install standard shed felt on any building we are responsible for. For the apex roof of the Irene XL, we strongly recommend upgrading to Britmet composite slate tiles or natural slate. Please contact us to discuss roofing upgrade options and pricing.

Bespoke Options

Electrical lighting, heating, insulation upgrades — we can accommodate all of these as part of the installation. Contact us to discuss your requirements before placing your order.

Frequently Asked Questions

Do I need planning permission for the Palmako Irene XL?

In most cases, no. At 5.3m x 5.7m and 321cm overall height, the Irene XL 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 321cm height, the Irene XL exceeds the 300cm eaves height threshold that applies to buildings within 2 metres of a boundary — so siting will be important. 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 and timber treatment?

Yes. Foundation preparation and installation and Smart Seal timber treatment are both included. Roofing upgrades (Britmet composite slate or natural slate) are available at an additional cost — please contact us to discuss. No hidden costs, no separate groundworks quotes.

What type of foundation does the Irene XL 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 porch be positioned on either side?

Yes. The 5.2m² covered porch can be positioned on either side of the building to best suit your garden layout. We will confirm the preferred positioning with you before installation.

What roofing do you install on the Irene XL?

We will never install standard shed felt on any building we are responsible for. We strongly recommend upgrading to Britmet composite slate tiles for a premium, long-lasting finish. Natural slate is also available. Please contact us to discuss options and pricing.

How long does installation take?

The Irene XL is typically installed in two to three 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 use the Irene XL as a year-round garden room or home office?

Yes. The 44mm Nordic spruce walls provide good thermal mass and the double-glazed windows and doors minimise heat loss. For year-round comfort in all weathers, we recommend adding internal insulation boards and a suitable heating source. Please contact us to discuss options.

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.
