Lillevilla Seili – 12,3 m² / 34 mm

Spacious Dual-Sided Storage Shed

The Lillevilla Seili is a versatile dual-sided storage shed suitable for both homes and summer cottages.

The floor area of this model is 12.3 square meters, with the double-door section measuring 7.2 square meters and the single-door section measuring 4.8 square meters. The shed is 4.1 meters wide and 3 meters deep. The ridge height is 2.3 meters, and the lowest interior height is approximately 1.75 meters. The double door makes it easy to store large items, such as a riding lawn mower or an ATV. The smaller storage space can be used as a wood storage area or for garden tools. Alternatively, it can be converted into a spacious outhouse.

Delivery Contents

The product package includes logs, doors, windows, as well as floor and roof boards, along with fittings, nails, and screws. For roofing material, you can order Katepal TopTite 3 roll roofing from us via this page. We do not recommend tile or shingle roofing. The roofing material must be installed immediately after the structure is erected.

The components of the shed are machine-prepared at the factory. However, since this is a construction project, ensure you have common tools on hand, such as a measuring tape, level, hammer, saw, screwdriver, and drill. Check the builder’s inspection list for additional materials to procure and other considerations via this link. Assembly tips are also compiled here.

Surface Treatment

The building’s surface treatment must be carried out promptly after erection, provided weather conditions allow. Use breathable surface treatment products designed for log surfaces. Paint that forms an impermeable plastic film must not be used. Tips for surface treatment can be found via the link on this page.

Building Permit

Check the need for a building permit in advance with the building permit authority of your municipality. You can download the required drawings for the permit application from this page or request them from our customer service.
