Project description

This mountain lodge is located at the trailhead for Preikestolen, «the Pulpit», a characteristic mountain formation jutting out above the Lysefjord. It contains 28 bedrooms, café, restaurant and conference facilities. The project is developed along two conceptual lines: one concerning the relationship to the landscape, the other the structural strategy. The main volume has been carefully placed and distributed in relation to the local topography, giving each of the internal spaces a different relationship to the surrounding views. The structure is based on Holz100 prefabricated solid timber elements. This system has been stretched to its utmost limits both in terms of geometry and in terms of structural spans. Displacements, cuts and hollows create a variety of spaces within the standards of the system.

Energy
Compact building form. South orientated glazing/windows. Well insulated building envelope with few cold bridges. Combination of passive house- and low energy windows. Low air leakage external envelope. Balanced ventilation with a combination  of rotating plate heat recovery and plate exchanger. Heat pump connected to nearby water source  (water-water). Remaining heating demand on cold days met by wood oven ("Hypocaust oven")  .

Timber technology
Massive wood construction with shear walls running through both floors of the building. Specially produced panels with built in reinforcement (columns beams and angled planes providing stiffness) . External walls and roof in massive timber with externally fixed insulation and cladding.

Environmentally friendly materials
Small number of 'pure' materials with use of quality materials throughout. Large amount of untreated surfaces (reduced chemical usage). Dowelled (beech dowelled) massive timber elements, without use of glue. Recycled newspaper insulation (cellulose insulation). Wood fibre plate sheathing boards. 'Fire seal' (metal louvres which close air passages when exposed to high temperatures) mounted behind the timber facade to reduce spread of fire (thereby avoiding impregnation of facade with fire retardant). External cladding made from 100% heartwood, treated with jernvitrol (accelerated weathering) Slate and solid timber floors. Untreated concrete floor finish in wet rooms. Bathroom walls made from glass, kitchen walls from steel. Fireplace plasters with lime and horse manure. Environmentally certified windows (Swan mark). Seven products with environmental documentation approved by Norwegian Wood.

Universal design
Access route suitable for physically disabled, stone edging and well lit railings.
Guidelines (light coloured in contrast to slates) at the arrival area leading towards the entrance and through the reception towards the lifts and bedrooms. Automatic door opener on main entrance door. Principal functions such as reception, cafe / restaurant / shop / disabled WC are immediately accessible on the first floor. Cafe / restaurant / reception have low countertops suitable for wheelchair users (90cm high). Tactile map with plan of building and Braille signage at the entrance. Colour contrast between floors and walls (slates/timber) for good orientation. Recessed lighting in ceiling follows the direction of corridors. Doors in strongly contrasting colours with different colours on each floor allow for easy orientation. Four bedrooms are sized for wheelchair users.
