Preikestolen Mountain Lodge

Share this Post:

Preikestolhytta is a mountain lodge for the Norwegian Trekking Association at the Pulpit, in the Lysefjord, Ryfylke. Completed November 2008.

Building 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.


Massive timber 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.

Passive Design Measures

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.

Energy Generation

Energy target: class A 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”).

U-values: Roof: 0.12 W/m²K, Floor: 0.08 W/m²K,External wall: 0.14 W/m²K, Windows: 1.0 W/m²K


Environmentally friendly materials Small number of ’pure’ materials with use of quality materials throughout. Large amount of untreated surfaces (reduced chemical usage) Dowelled (birch 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.


Preikestolen Mountain Lodge is part of the Norwegian Wood project where developing and distributing knowledge and experience is a key issue. In Norwegian Wood this happens through interdisciplinary collaboration and advice, and high ambitions for each building project, culturally as well as technically.
