The model differences relate to the thickness of the walls, style of windows (see graphic below) the height of the building and whether or not Tongue & Groove (T&G) flooring is included.

In most cases ….

Premium models are one row of boards higher than the Economy PLUS and Economy Models. Premium models have better windows than Economy PLUS and Economy models.

Premium and Economy PLUS 44mm buildings come with 19mm floorboards.

68mm wall models are Premium Specifications (taller, better quality windows) and have 28mm floorboards.

Economy models …Where an Economy model is available, no ground level flooring is included. When models are ordered without floorboards (ie Economy models), if the building has a loft or second floor, those floorboards ARE included. When buildings are ordered without Floorboards, there is a longer delivery time.

Some Premium models have Premium Plus Windows which are automatic Tilt & Turn. This means it is that the window tilts – open at the top to allow ventilation. Windows can also be swung open from the side hinges.
