Fully Installed Palmako Sandra L Multi-Room Log Cabin | Annexe | Guest House | Summer House | 25.6+11.1m² | 44mm | 7.9x3.7m

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

The Palmako Sandra L is in a different class to anything else in this catalogue. This is not a garden cabin — it is a fully functional, three-room timber building with 25.6m² of internal living space, an 11.1m² covered veranda sheltered by a sweeping 177cm front roof overhang, and the construction quality to serve as a garden annexe, a guest house, a holiday home, or a premium summer house for decades to come.

Built from 44mm Nordic spruce with wind-tight double hook joints, double-glazed windows and doors throughout, and laminated timber roof beams for structural strength, the Sandra L is engineered to a standard that most garden buildings simply cannot match.

The price shown includes the full supply and professional installation of your Palmako Sandra L anywhere on Mainland UK, including foundation preparation and installation, full structural assembly, 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.

Roofing Upgrades

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

Frequently Asked Questions

Do I need planning permission for the Palmako Sandra L?

In most cases, no. The Sandra L at 7.91m x 3.70m and 335cm 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, and timber treatment?

Yes, completely. Foundation preparation and installation, full structural assembly including the veranda, and Smart Seal timber treatment are all included. Roofing upgrades (Britmet composite slate or natural slate) are available at an additional cost. No hidden costs, no separate groundworks quotes.

What type of foundation does the Sandra L 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 do you install on the Sandra L?

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 that suits the scale and character of this building. Natural slate is also available. Please contact us to discuss options and pricing.

How long does installation take?

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

The Sandra L is one of the most capable garden buildings we install for annexe and guest house use. 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.
