Construction element, a module and a construction comprising such an element and method of assembly of such a construction

A method for assembly of a construction according to a predetermined scheme, the construction comprising a plurality of structural elements and service installation components, said structural elements comprises;

• at least one foundation element, at least one room unit, a plurality of facade elements, and a plurality of construction elements for attachment of said structural elements, wherein the number and position of each structural element is determined by the predetermined scheme, said construction element comprising an upper plate member and a lower plate member, having a same width and a same length and extending parallel to each other at a first distance-, wherein the upper and lower plate members are connected to each other along longitudinal sides of said plate members by means of a plurality of intermediate beams, wherein each end portion comprises at least one upper and at least one lower distance element having a width and a height, and being arranged at an upper surface and a lower surface of said end portions respectively, wherein a longitudinally transversal cross section of each end portion forms a cross-shaped circumference, said circumference comprising four right angled abutment surfaces, defined by the plate members and the distance elements, the method comprising the step of:
• a) arranging a number of construction elements at the at least one foundation element by means of coupling each downwards directed distance element of each construction element to the at least one foundation element, defining a first floor level by means of the construction elements.
