Fully Installed Palmako Sandra S Holiday Summer House | Multi-Room Log Cabin | Guest House | Annexe | 21.5+3.7m² | 70mm | 6.2x4.7m

Fully Installed Palmako Sandra S Holiday Summer House | Multi-Room Log Cabin | Guest House — Professionally Installed Across Mainland UK

The Palmako Sandra S is the most substantially built structure in the Sandra range — a traditional, multi-room holiday summer house constructed from 70mm solid Nordic spruce logs, with a covered veranda, impregnated decking, classic railings, and the kind of construction quality that is more commonly associated with a permanent building than a garden cabin.

With 21.5m² of internal living space across multiple rooms, a 3.7m² veranda, five windows, and three doors — including a flexible single door and window that can be positioned on either side to suit your garden — the Sandra S is a building that works equally well as a guest house, a garden annexe, a holiday home, or a large, premium garden room.

The price shown includes the full supply and professional installation of your Palmako Sandra S anywhere on Mainland UK, including foundation preparation and installation, lead valleys and roof shingles, and timber treatment with Smart Seal applied to all external timber. There are no hidden costs, no separate groundworks quotes, and no surprises. What you see is what you pay.

70mm Walls — Built to a Higher Standard

The Sandra S is not simply a larger garden cabin — it is a fundamentally different class of building. Its 70mm solid log walls are nearly double the thickness of a standard 44mm cabin, providing exceptional thermal mass, superior sound insulation, and a structural robustness that makes the Sandra S feel — and perform — like a permanent structure.

The wind-tight double hook joints lock every log course together with precision, eliminating draughts and ensuring the building remains weathertight in even the most challenging conditions. The 28mm tongue-and-groove floor boards — significantly thicker than the 19mm boards found in most cabins — provide a solid, substantial underfoot feel that reinforces the premium nature of this building throughout.

The covered veranda with impregnated decking and classic railings extends the usable space outdoors and gives the Sandra S the kind of traditional cottage aesthetic that makes it a genuine focal point of any garden. Five double-glazed windows with grid detailing and three doors — including glazed and half-glazed options — ensure the interior is bright, welcoming, and full of character.

Every component is precision-engineered in Estonia from slow-growing Nordic spruce, and our experienced installation team handles the entire process from foundation preparation through to the final fixing, leaving you with a finished building that is ready to enjoy from day one.

Roofing Upgrades

We will not install standard shed felt on any building we are responsible for. For the apex roof of the Sandra S, we strongly recommend upgrading to Britmet composite slate tiles — a premium roofing solution that complements the traditional character of this building beautifully and provides outstanding long-term weather protection. Natural slate is also available for those who want the ultimate finish. Please contact us to discuss roofing upgrade options and pricing.

Bespoke Options

If you would like to customise your Sandra S further — whether that is adding electrical lighting, heating, plumbing connections, insulation upgrades, or any other feature to enhance it as a guest house, annexe, or holiday home — we can accommodate this 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 Sandra S?

In most cases, no. The Sandra S at 6.2m x 4.7m and 320cm overall height will fall within Permitted Development rights for most residential properties in England and Wales, provided it is used as an ancillary garden building and not as a primary dwelling. It must be sited within the curtilage of a dwelling house, not forward of the principal elevation, and must not cover more than 50% of the garden area. If your property is listed, in a conservation area, or in a National Park, different rules apply. We always recommend confirming with your local planning authority before ordering. We can provide a site plan and specification document to support any planning enquiry.

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

Yes, completely. The price shown includes foundation preparation and installation, full structural assembly including the veranda and decking, and Smart Seal timber treatment applied to all external timber. Roofing upgrades (Britmet composite slate or natural slate) are available at an additional cost — please contact us to discuss. There are no hidden costs and no separate groundworks quotes.

What type of foundation does the Sandra S 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 or concrete pad foundation. 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, providing an additional barrier against ground moisture. 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.

What roofing do you install on the Sandra S?

We will never install standard shed felt on any building we are responsible for. The Sandra S has a 20.4° apex roof and we strongly recommend upgrading to Britmet composite slate tiles for a premium, long-lasting finish that suits the traditional character of this building. Natural slate is also available. Please contact us to discuss roofing options and pricing before placing your order.

How long does installation take?

The Sandra S 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 and keep you updated throughout the process.

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 against weathering, moisture ingress, UV damage, and biological growth. After 10 years, a single re-application coat is all that is needed.

Can the Sandra S be used as a permanent guest house or annexe?

The Sandra S is well suited to use as a guest house or holiday annexe. For permanent residential occupation, planning permission would typically be required regardless of size, and the building would need to meet Building Regulations for habitable use. We can advise on insulation upgrades and connect you with the appropriate professionals. Please contact us to discuss your specific requirements.

Can I add electricity, heating, or plumbing?

Yes. We can accommodate electrical, heating, and plumbing installations as bespoke additions to the standard package. Please contact us before placing your order to discuss your requirements.

How long does delivery take after ordering?

Typically, we aim to have your Sandra S installed within 6 to 12 weeks of order confirmation. Please contact us if you have a specific deadline in mind.

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 if you are unsure whether your location is covered.
