Optional Extras Dunster House Greenhouse

We understand that everybody’s needs are different, especially when it comes to their garden.  With the copious amount of hints and tips online regarding installation, staging, ventilation and storage, it is easy to see why we provide different optional extras for our greenhouses. It’s allowing you to design your greenhouse to fit your needs.  You can get greenhouses that are made of plastic but the best glazing material, according to the RHS, is glass. Glass lets 90% of light through and does not degrade in the sun.


Possibly the most important aspect of your greenhouse. Staging provides you with extra surfaces to organise your plants, pots and tools. That way you make the most out of the space provided.  We offer two types of staging, fixed and free standing.

Free standing

Optional Extras Dunster House GreenhouseThe free standing staging stands at 2’6” high, 1’8m wide and 3’11” long and is made from pressure treated timber which is protected against rot and infestation.  One of the main benefits of free standing staging is the flexibility it gives you. You can choose where and how you use it.  As the seasons change, and the needs of flower exposure change, you can move the staging to wherever it is beneficial.
The angled legs maximize the amount of available space underneath. Therefore it gives you a larger space to store your plant pots.

Optional Extras Dunster House GreenhouseFixed Staging

The fixed staging is available in three different types; single, double and all round staging.  Each one features staging that is fixed, supported by 90mm x 20mm timbers, just beneath the glass windows of your greenhouse.  Once again supported by angled legs to provide space beneath, the staging has spaces between each board to allow spills and dirt to fall through, making cleaning easier.
Although not as flexible as the free standing option, fixed staging offers you a permanent fixture within your greenhouse, allowing you to garden in comfort whilst knowing where everything is.  You can still move your plants around dependant on the season.


Greenhouses are vulnerable to overheating in from spring through to autumn, which often results in plants not surviving unharmed.  The high levels of heat cause them to dry out and dehydrate.  Plants need three things to survive this; humidity, shading (which you can control via the staging above) and air circulation.  We offer two types of circulation which can be used independently or together to increase air flow within your greenhouse.

This is probably the most popular amongst ventilation, the roof.   These skylights are made of 4mm toughened glass and have a metal arm so you can keep these open.  By opening these, even for a few hours a day, it helps remove the stagnant air and prevents the occurrence of mildew.  The RHS advise that you should have roof ventilation “ideally on both sides of the ridge and equivalent to 15-20% of the floor area.” [i]

Optional Extras Dunster House GreenhouseSide Ventilation

Adding opening side panels to your greenhouse allows fresh air to freely circulate inside. It also offers great protection against the possibility of mildew and stagnant air build up.  To achieve maximum efficiency, you would ideally have both roof and side ventilation.

These options are the staple extras that you can get with each greenhouse.  They do not show how the pressure treated timber and double sliding doors increase the space and longevity of your greenhouse.
