If you're awaiting installation of your new Rhino Greenhouse, or you're looking to get more information in advance of making a purchase, you can refer to the guides below.


Base Plans

These guides contain precise measurements for Rhino Classic and Premium greenhouses and helpful suggestions for base preparation.


Site and Base Preparation Guidelines

Careful and correct site and base preparation is absolutely essential for correct installation of your Rhino greenhouse. Making the site safe for installation is as important as technical considerations.

Preparing the Site

  • Clear the space of all potential hazards.
  • Ensure there is sufficient space away from the site itself to lay out and assemble the greenhouse components.
  • maintain a clear perimeter that extends at least 2ft around all sides of the greenhouse itself. You should have enough working room around the outside the greenhouse to safely work and use a stepladder, including carrying and manoeuvring large panes of glass.
  • Consider having convenient access to electricity and water, if you so wish.


Rhino Greenhouse Base Options

The great news is that a Rhino greenhouse allows for flexibility, giving you options when choosing a base that is right for you.
You can choose one of the options below based on how you want to grow, the aesthetic you are looking for or if your chosen positioning of your Rhino is dictated to you by quality of foundation.


Soil Option

Unlike most other brands of greenhouse, Rhino greenhouses can be sited directly onto soil. This is only possible because the Rhino greenhouse is so strong. Its combination of a sturdy base and framework mean it will happily sit on a properly prepared soil site.

In most situations soil is a perfect foundation, so long as it is level and fully compacted down (freshly dug soil will shift too much to create a stable foundation on which to build). Whilst you do need to take time and care to properly prepare a soil site to the required standard, it does have the considerable advantage of doing away with the extra cost and time of building hardstand foundations. Take note of the quality of the soil itself - very heavy clay, waterlogged or very sandy soil can cause problems; a good amount of loam is ideal.

The greenhouse is held in its permanent position by concreting in place using the specially supplied brackets and J shaped ground anchors.

N.B. The ‘low threshold door’ feature on the Rhino greenhouse is most easily incorporated onto a soil site, by the use of paving slabs (please note, these are not supplied or laid with the greenhouse).


Hardstanding Option

The versatility of the Rhino greenhouse also allows installation on a hardstand. There are a number of different types of hardstanding bases, all of which must be smooth and level:

  • Paving Slabs: must be laid flat and level and should ideally create a site that is slightly larger than the greenhouse footprint size.
  • Concreted Area: same as above.
  • Brick or Block Perimeter Plinth: must be laid on suitable footings so that it is level, square and exactly to the correct greenhouse footprint size.

N.B. The ‘low threshold door’ feature on the Rhino greenhouse is most easily incorporated onto bricks or blocks, by using a protective timber strip (please note, this is not supplied with the greenhouse).

On all types of hardstand base the greenhouse is held in its permanent position by plugging and screwing down using the specially supplied base brackets and, wherever possible, the supplied rawlbolts. However, please note that some hardstand bases may require a different fixing, which is the customer’s responsibility to source and use. We also strongly recommend that the top course is laid ‘frogs down’ to give a smooth surface on which to sit and fix down the greenhouse and that bricks/blocks are of a type that will allow drilling without cracking or splintering.

Rhino Greenhouses do not recommend the use of Hardcore or Hogging as base materials, due to issues surrounding levelling and securing the greenhouse.
