Improvements in or relating to building structures

A building structure comprising:

• a wall, the wall comprising:
• inner and outer face surfaces formed from glass fibre reinforced board;
• a support structure comprising one or more rigid components positioned between the inner and outer face surfaces;
• and
• a quantity of low-density cellular lightweight concrete (CLC) which substantially fills the space between the inner and outer face surfaces,
• wherein:
• the building structure further comprises a ceiling or a floor, which forms part of the same storey of the structure as the wall, wherein the floor or ceiling comprises at least one face surface formed from glass fibre reinforced board, and the floor or ceiling contains a quantity of low-density CLC which forms a unitary, continuous and unbroken quantity of CLC along with the CLC which is within the wall.

A method of forming a building structure, the method comprising:

• providing inner and outer face surfaces for a wall formed from glass fibre reinforced board;
• providing a support structure, comprising one or more rigid components positioned between the inner and outer face surfaces;
• providing one or more further face surfaces to define a ceiling space, above the wall, or a floor space, below the wall;
• and
• pouring a quantity of low-density CLC into the space between the inner and outer face surfaces, and into the ceiling space or the floor space, so that the wall is filled and the ceiling space or floor space is filled, or partially filled, with the low-density CLC in one operation.
