An integrated construction panel comprising: a. an internal wall section; b. an internal studs' array operably coupled to the internal wall section, extending externally; c. a moisture control layer coupled to the internal wall section; d. an internal thermal insulation layer, e. an external thermal insulation layer; f. an external wall section; and g. an external studs' array operably coupled to the external wall section, extending internally, wherein, the internal studs' array is staggered with respect to the external studs' array; each of the internal wall section and the external wall section consists of a slab having front side and a back side (162, 161; 181, 182), each stud in the internal studs' array has a proximal end coupled to the front side of the internal wall section and a distal end opposite the proximal end; and wherein each stud in the external studs' array has a proximal end coupled to the back side of the external wall section and a distal end opposite the proximal end, the distal end of each of the studs in the internal studs' array defines a gap between the distal end and the back side of the external wall section, the distal end of each of the studs in the external studs' array defines a gap between the distal end and the front side of the internal wall section, characterised in that the gap between the distal end of each of the studs in the internal stud's array and the back side of the external wall is no less than about 10 mm, and the gap between the distal end of each of the studs in the external stud's array and the front side of the internal wall is no less than about 10 mm characterised in that the moisture control layer is fire resistant and the panel further comprises a waterproof breathable membrane external to the external wall section, that has fire retardant additives, or is fire resistant glass fibre. a. an internal wall section;
