1. Storage of cabin kit package at the site, sorting and checking the parts Machined wall planks and other parts are delivered in protective wrapped unit(s). If the kit will not be immediately installed, it should be kept indoors or otherwise well protected until ready to be set up. The package should be elevated from the ground to avoid absorbing moisture and stored on a leveled base. These instructions include parts list and drawings of the wall construction.
4.0. Foundation timbers Begin the set up by assembling the joists at equal distances apart across the area of the base according to the separate foundation drawing. Fasten the joists to the foundation, for example with angle irons (excluded). The joists included in the kit are the same shared by various kit models. Check the length of joists against the parts list and if necessary trim them.
.1. Building up the frame When building up the frame please use the wooden hammer blocks for assembly marked with the letter X. NEVER HAMMER THE WALL BLANKS – ALWAYS USE A BLOCK IN BETWEEN. Place the block on top of each wall plank (tongue side) and hit the assembly block so that the plank goes to the bottom (interlock). Use only moderate force to avoid breaking the planks. If the plank does not easily fit into place, check that it is straight on the groove joint of the plank underneath.
. Installing the door and the window After 3-4 layers of wall planking, it's time to install the door first. 5.1. A single door A single door is prehung, i.e. it comes in its frame. The frame including the door will slip into its place from upper side of the opening (hinges outside), drawing 7. Door frames are machined so that the planks fit into the channel on the sides.
Because wood as a material expands and contracts with seasonal humidity changes, it may be necessary to later adjust the door hinges by turning them inward or outward. For example if the door seems to be too big compared with the frame, rotate all the hinges inward. 5.3. Assembling the window Slide the window(s) into place from the upper side of the opening in the same way as the door. Screw the window handle in place and check that the window is functioning correctly.
6. Gable triangles and supports of the roof (purlins) Please note that the uppermost planks of side walls are beveled to follow the inclination of the roof. The uppermost planks on some models are short, lower and beveled (please see the drawings of wall construction). They will be screwed or nailed (require pre-drilling) to the plank below. When the walls are complete 2-3 people are needed to install the gable triangles.
6.1. Gable triangles consisting of several parts or separate planks Gable triangles for some models consist of several parts or separate planks (please see the drawings of wall construction). Assemble the gable triangles following the drawings and fasten the parts together with 4” nails (countersink nails aprx. 1/16” deep into the planks). 7. Floor Floor boards have been moulded to Tongue and Groove (T&G) pattern. The back side is beveled and has two furrows. It is normal that the back side has wane on it.
Roof boards have lightly rounded edges on the face (assembly face down as the ceiling) and bevelings and furrows on the back (assembly upwards as the roof underlayment). The back side has usually wane on it. Again this is not a defect but a characteristic of the product and like the floor boards, these have only one good side. Safety first! Begin nailing the roof from front.
8.2. Covering material for roof Final roofing material should be installed immediately. If it is delayed, temporary protection tarping is required. Only light material, for example bitumen shingles or lightweight steel are suitable roof coverings. The load on the roof boards should not exceed 40 lbs per sq. ft. Fascia and barge boards should be installed after the roof covering is fitted (drawing 12).
roof. Finally, install the felt strip on top of the ridge. The roofing felt included in the delivery is for temporary use only and it must be replaced with suitable covering material, for example, shingles within six months. 8.4. Roofing shingles If you use roofing shingles (not included in the kit) , please see drawings 14a-14e. The bitumen shingles are to be attached directly to the roof boards. They should be fitted when the ambient temperature is above +5ºC.
The extra pieces for roof ridge are produced by cutting off the strips from the bitumen shingles. (Pic D). Fasten the pieces on the roof ridge (overlap about 2”) by folding the pieces to both sides of the ridge, see Pic. E. Nail the pieces with clout nails approximately every 4”. When you have finished fitting the shingles, fix the wind cover boards and front fascia.
9. Protection against storms Although your Lillevilla cabin is a solid construction, it is worth protecting it against heavy winds. Fasten the joists to the foundation like previously described. Note! Fasten the roof to the building and the cabin to the foundation and take special care in open areas where there is the possibility of heavy winds and storms. You will need extra fastening material excluded from the delivery. 9.1.
9.3. Storm rods If storm rods are included, slide them into the ready drilled holes in the corners of the building according to the drawing 17 (nut and washer to both ends). Please take care that the upper end of the rod is below the level of the gable triangle so as not to impair the level of the roof boards. Check the nuts regularly and tighten lightly when needed.
10. Assembling the terrace (optional) Begin by fastening the foundation joists (T14) in place in the same way as you did with the building itself. The short foundation joists (T15, if included) should be placed under the parapets at the sides of the terrace entrance. They also act as a base for the first floor board. The two half planks (T5) should be assembled on the outermost foundation joists so that the planks extend past the edge of the beam.
Screw the parapets of the terrace to the floor using the angle irons (T13). Then finish the parapets by fastening the balustrades (T9, T10) to them and assemble the U-profiles (T11) to both sides of the entrance. Fasten the facing plank (T18, if included) in front of the foundation timber. Finally fasten the parapets to the building with four T12 boards. 11. Finishing of the building 11.1.
Protect the floor (also the terrace floor) during the treatment of walls. Also treat the internal floor with stain or paint before use. 13. Care and maintenance Safe long-term use of the building requires regular checking, possible reparation of the fastenings and inspecting the condition of the parts. Pay particular attention to the roof construction, covering material, doors and windows, foundation fastenings, the protection against storm and surface treatment.
