Low maintenance granny annexes

All of our granny annexes are low maintenance, as the structure is clad in a weather resistent membrane on the external walls before a low maintenance cladding is added over the top.

Low maintenance cladding:

All garden annexes are supplied with Hardie Board external cladding as standard. This is a tough, weather resistent material that creates a low maintenance finish for any granny annexe or garden office or building.

Low maintenance roof covering

The roof of the annexes is produced in SIP construction, which is then covered with a weather resistent rubber roofing material - see our granny annexe specifications.

Low maintenance internal features

Internally, the walls are plastered, taped and skimmed, to provide a durable, low maintenance, smart and modern finish. You can choose to put carpet into your annexe, or use a lower maintenance option, such as laminate floor. Real wooden floors can last longer (although they will require occasional floor sanding and sealing), but a good laminate should last many years, depending upon the manufacturer and guarantee.


Prefer wood? Our team can spec up wooden granny annexes, in the same layout designs, and still made from SIP panels with treated wooden cladding as an alternative. The option uses a natural wood cladding if you prefer the look of wood on the outside, and if you go for this, the wood is treated for weather resistence and although not as low maintenance as Hardie Board, as it is wooden, it should still last a long time. If you want a low maintenance / virtually no maintenance cladding, don't go for wood. With wood, you may then decide to stain it or treat it periodically.  The wood will weather in sunlight, due to the effects of the UV light on the surface. If you prefer, a surface pigment treatment can be applied to give alternative colours.

Low maintenance windows and doors

The UPVC double glazed windows supplied with the complete annexes are also low maintenance, as are the external doors. This completes what should be a comfortable, easy to maintain and smart, modern building for many years to come.
