Treated Timber

All timber is ‘Double Vac’ pressure treated 5ths grade Scandinavian Red Wood, which is also externally base coat treated with a Sovereign straw coloured solvent based wood preservative.

Bespoke Design & Planning Rules


A full customer building service is available. All sizes, height dimensions and roof pitch angles are fully adjustable.
The overall height of a building depends on the internal height and the roof pitch angle.

As standard the internal height clearance of a Lushington Building can be anything from 6’2″ to 6’8″ (1880mm x 2030mm) and the roof can be pitched at 5, 8, 15, 22.5 or 35 degree.
The choice is yours.

General Planning Rule

If you locate a building within 2 metres off a boundary the overall height (from ground level) must not exceed 2.5 metres (8 1/2ft).

If the building is located more than 2 metres off a boundary, the overall height must not exceed 3 metres for a flat sloping roof or 4 metres for a pitched roof.

If your proposed building exceeds the permitted height we would be happy to process a Planning Application on your behalf for an additional £629.

High Quality Buildings

Our Buildings are constructed in our Isle of Wight workshops, from custom-designed garden rooms, offices and studios to standard garden buildings including sheds, garages, summerhouses, and specialist buildings such as aviaries, beach huts, stables and children’s play rooms.

All of our garden buildings can be supplied in kit form for self assembly or completely installed for you by the Lushington Garden Buildings team, wherever you are in the UK.

Friendly and Professional Approach

From the top down our customer service is something we strive for excellence in. From the moment you call to the manufacturing team to the team that assembles your building, you will find us keen to make the whole experience as smooth as possible.

The Turnaround

All of our hand-crafted sheds can be built, delivered and assembled within 2 - 6 weeks of an order being placed. In the peak season from March to September this may increase up to two weeks, but here at Lushington Garden Buildings our team are always mindful of timescales and the individual needs of all of our customers. All of our garden rooms and workshops can be delivered and assembled within 6 - 12 weeks whatever the time of year.

Occasionally we have onsite buildings that are ready to go and with stock and sale options it can sometimes workout that buildings can have a much faster turnaround depending on work load and availability of staff.
