Fully Installed Palmako Sandra M Traditional Holiday Log Cabin | Multi-Room with Mezzanine | Guest House | Annexe | 29.9m² | 44mm | 6.1x4.1m

Fully Installed Palmako Sandra M Traditional Holiday Log Cabin | Multi-Room with Mezzanine | Guest House — Professionally Installed Across Mainland UK

The Palmako Sandra M is the most complete holiday cabin in the Sandra range. With 29.9m² of internal floor space across three rooms — a generous living area with natural light from two directions, a bedroom, and a small bathroom — plus a mezzanine level that adds extra sleeping space or a children’s play area above, this is a building that functions as a proper self-contained holiday retreat from the moment it is installed.

Built from 44mm Nordic spruce with wind-tight double hook joints, double-glazed windows and doors with grid detailing, and laminated timber roof beams supporting a steep 32.1° apex roof that rises to 370cm, the Sandra M has the character and warmth of a traditional Scandinavian holiday cottage.

The price shown includes the full supply and professional installation of your Palmako Sandra M anywhere on Mainland UK, including foundation preparation and installation, full structural assembly including the mezzanine, roof shingles fitted as standard, 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.

If you would like to upgrade the roof to Britmet composite slate tiles, this is available for an additional £2,000. Please contact us when ordering to arrange the upgrade.

Frequently Asked Questions

Do I need planning permission for the Palmako Sandra M?

In most cases, no. The Sandra M at 6.05m x 4.10m and 370cm 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.

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

Yes, completely. Foundation preparation and installation, full structural assembly including the mezzanine, roof shingles, and Smart Seal timber treatment are all included. The only optional extra is the Britmet composite slate roof upgrade at +£2,000.

What type of foundation does the Sandra 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.

What roofing is fitted as standard on the Sandra M?

We fit a premium shingle finish to the apex roof as part of the installation price. We will never install standard shed felt on any building we are responsible for. For those who want the very best finish, we offer an upgrade to Britmet composite slate tiles for an additional £2,000.

How long does installation take?

The Sandra M 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 the Sandra M be used as a permanent guest house or annexe?

The Sandra M is well suited to use as a guest house or holiday annexe. For permanent residential occupation, planning permission would typically be required and the building would need to meet Building Regulations for habitable use. Please contact us to discuss your specific requirements.

Can I add electricity, heating, or plumbing?

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

How long does delivery take after ordering?

Typically 6 to 12 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.
