Fully Installed Palmako Cecilia S Modern Log Cottage | 2-Room Annexe | Commercial Office | Guest House | 14.2m² | 70mm | 5.2x3.3m

Fully Installed Palmako Cecilia S Modern Log Cottage | 2-Room Annexe | Commercial Office | Guest House — Professionally Installed Across Mainland UK

The Palmako Cecilia S is the entry point to the Cecilia range — and it sets the bar high. A compact, two-room modern log cottage with 14.2m² of internal floor space, 70mm solid Nordic spruce walls, two aluminium sliding doors with 24mm toughened energy glass, and the same premium specification that runs throughout the entire Cecilia range. This is not a scaled-down version of something better — it is a complete, fully specified building in its own right.

At 5.2m x 3.3m, the Cecilia S is the most compact model in the range, but it loses nothing in quality. The 70mm log walls, 28mm floor boards, aluminium-framed double glazing, and flat pent roof are identical in specification to the larger Cecilia models. What changes is the footprint — and for many gardens, plots, and projects, the Cecilia S is exactly the right size.

Whether you are looking for a compact garden annexe, a private commercial office, a guest room, or a contemporary two-room retreat, the Cecilia S delivers the full Cecilia experience in a building that fits where larger models cannot.

The price shown includes the full supply and professional installation of your Palmako Cecilia S anywhere on Mainland UK. This means everything: EPDM rubber roofing, 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.

Full Specification. Compact Footprint.

The Cecilia S was designed for customers who want the quality and character of the Cecilia range without the footprint of the larger models. Its two-room layout makes intelligent use of the 5.2m x 3.3m floor plan — a main living or working space and a separate room for sleeping, storage, or private use — and the two aluminium sliding doors open the building to the garden in a way that makes the interior feel far larger than the floor area suggests.

The 239cm wall height provides full, comfortable standing room throughout. The 24mm toughened double glazing (4-16-4 specification) with energy glass coating keeps the interior warm in winter and cool in summer. The aluminium frames are maintenance-free, lockable from both sides, and give the Cecilia S the same clean, contemporary finish as every other model in the range.

The flat pent roof at 3° pitch is finished with EPDM rubber roofing as part of the installation price — the only appropriate professional-grade finish for a roof of this specification. The 70mm Nordic spruce walls provide exceptional thermal mass. The 28mm tongue-and-groove floor boards are substantially thicker than standard cabin flooring. And every component is precision-engineered in Estonia from slow-growing Nordic spruce, installed by our experienced team from foundation to final fixing.

Key Features

• Two-room layout — 14.2m² of internal floor space across two separate rooms in a 5.2m x 3.3m footprint — a main space and a private room, making the Cecilia S ideal for a home office with a separate meeting room, a guest suite, or a compact annexe
• Two aluminium sliding doors — opening the building to the garden from the front elevation, with 24mm toughened energy glass in maintenance-free aluminium frames
• Aluminium-framed double-glazed windows and doors throughout — 24mm toughened double glazing (4-16-4 specification) with energy glass coating, providing outstanding thermal performance, sound insulation, and a contemporary finish
• 239cm wall height — full, comfortable standing height throughout, with a 279cm overall height giving the building a clean, low-profile contemporary silhouette
• 70mm solid Nordic spruce log walls — the same premium wall thickness as the largest models in the Cecilia range, providing exceptional thermal mass, superior insulation, and outstanding structural robustness
• Flat pent roof at 3° pitch — a 29.3m² roof with 19mm roof boards
• EPDM rubber roofing — included as standard — the flat pent roof requires a professional-grade waterproofing membrane. We install EPDM rubber roofing on every Cecilia S as part of the price. We will never use standard shed felt on any building we are responsible for.
• Foundation preparation and installation — included — we assess your site and install the most appropriate foundation as part of the price, whether that is ground screws, a concrete slab, or composite pads. No separate groundworks quote.
• Composite DPC strip, ground membrane, and anti-insect and rodent mesh — included as standard — we fit a composite damp-proof strip along the base of the foundation beneath all pressure-treated timber, lay a ground membrane beneath the building, and install anti-insect and rodent mesh as standard on every installation. These measures are not optional extras — they are part of how we build, because we want every building we install to last as long as possible.
• 28mm tongue-and-groove floor boards — substantially thicker than standard cabin flooring, on 45 x 70mm treated foundation joists
• Timber treatment with Smart Seal — included as standard — all external timber sealed as part of the installation, providing up to 10 years of protection against weathering, moisture, and UV damage. No additional treatment required after handover.

Frequently Asked Questions

Do I need planning permission for the Palmako Cecilia S?

In most cases, no. The Cecilia S at 5.2m x 3.3m and 279cm 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 (office, studio, guest room) 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 of the Cecilia S, EPDM rubber roofing, and Smart Seal timber treatment applied to all external timber. There are no hidden costs and no separate groundworks quotes. What you see is what you pay.

What type of foundation does the Cecilia 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, which are quick to install, do not require concrete, and are fully reversible. Where ground conditions require it, we can install a concrete slab or concrete pad foundation. We will advise you on the best option for your specific site during the pre-installation survey.

What extra protection do you install at foundation level?

Quite a lot — and this is one of the things that genuinely sets us apart. On every installation, we fit a composite damp-proof strip along the base of the foundation beneath all pressure-treated timber, which provides an additional barrier against ground moisture rising into the floor structure. 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.

How long does installation take?

The Cecilia S is typically installed in one to two days, depending on site conditions and foundation type. Ground screw foundations can be installed on the same day as the building. We will confirm the installation schedule with you in advance and keep you updated throughout the process.

What is EPDM rubber roofing and why is it used on the Cecilia S?

EPDM (Ethylene Propylene Diene Monomer) is a synthetic rubber membrane used as a professional-grade waterproofing solution for flat and low-pitch roofs. The Cecilia S has a 3° pitch flat pent roof — too shallow for tiles or shingles to perform reliably — and EPDM is the correct and only appropriate finish for a roof of this specification. It is the same material used on commercial flat roofs and modern residential extensions, with a typical lifespan of 50+ years. We install EPDM on every Cecilia S as standard. We will never use standard shed felt on any building we are responsible for.

What is Smart Seal and how long does it last?

Smart Seal is a clear, penetrating timber sealant that we apply 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. No additional treatment is required after handover. After 10 years, a single re-application coat is all that is needed to maintain the protection.

Can the Cecilia S be used as a permanent annexe or guest accommodation?

The Cecilia S is well suited to use as a guest room or compact annexe. For permanent residential occupation (i.e. someone living in it full time), you would typically require planning permission regardless of size, and the building would need to meet Building Regulations for habitable use — including insulation, ventilation, and potentially electrical and plumbing installations. We can advise on insulation upgrades and connect you with the appropriate professionals for any Building Regulations work. Please contact us to discuss your specific requirements.

Can I add electricity, heating, or plumbing to the Cecilia S?

Yes. We can accommodate electrical, heating, and plumbing installations as part of the build. These are arranged as bespoke additions to the standard installation package. Please contact us before placing your order to discuss your requirements and we will provide a tailored quote.

How long does delivery take after ordering?

Lead times vary depending on current demand and the time of year. Typically, we aim to have your Cecilia S installed within 6 to 12 weeks of order confirmation. We will confirm the expected timeline at the point of order and keep you updated throughout. Please contact us if you have a specific deadline in mind.

Do you install the Cecilia S 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.
