Introduction

Safety

Precautions when assembling a greenhouse:
The wearing of protective gloves and stout footwear is essential when handling glass and recommended even for
Polycarbonate which does not shatter but has sharp edges.
Protective goggles are recommended whilst handling glass and the glazing spring clips.
Assembly of the greenhouse frame is much easier with two people and essential for glazing with glass.

Site selection:

Choose a site in maximum light, ideally with no direct shade.
Avoid overhanging trees as much as possible as leaves will make regular cleaning necessary and broken branches are a
potential hazard.
Small trees, bushes or fences nearby can be helpful, acting as a wind break.
A position close to the house will make access easier for watering and tending and also make it easier to supply
power cables or automatic watering systems if required.

Site selection & preparation:

The site must be prepared so that the base of the greenhouse is level all round and checking with a spirit level is
required.

Base options & construction:

The use of purpose-made, galvanised steel bases is recommended.
They are made to fit the greenhouses.
It is easier to maintain a level and square foundation.
They are easy to install, requiring little expertise: full instructions are included in the pack.

Bases can also be constructed from bricks, blocks, or mounted on a concrete pad.
The bricks or blocks should be cemented onto firm and level concrete footings and the greenhouse frame drilled and
screwed to the base. Fig3.
If a concrete pad is made, it is important that this slopes towards the edges to prevent water ingress.
Time must be allowed for any concrete or cement to dry before mounting the greenhouse.

The base must be square or the greenhouse will be distorted. Fig1 & Fig2.
The greenhouse must be firmly fixed to the ground: the base should be constructed and installed before the
greenhouse assembly is undertaken.

Before you start:

IMPORTANT: Read the instructions completely before starting assembly.

• Construct the base first so that the greenhouse can be securely mounted when completed.

• Find someone to help you: it is much easier with someone to hold parts, pass tools etc. This is not very heavy
work so would suit most able-bodied people.

• Allow plenty of time:

rushing often causes errors and the re-doing of incorrect assemblies. If you have never built a

greenhouse before, it can take most of a day to carefully complete the construction.

• Have the right tools to hand:

•Cross head and flat head screwdrivers: electric ones save some elbow grease!

•10mm Spanner: a ratchet socket set is ideal or, even better, a 10mm socket that fits an electric drill or screwdriver.

•Safety clothing as recommended in the ‘Safety’ section.

• Lay out the parts by greenhouse section,

ideally around the base as shown, and check that all are present before

commencing construction. Lay on cloths or plastic sheets if there is any risk of scratching the parts.

• F

ollow the constr

uction sequence.

•Side sections

•Back section

•Front section

•Frame assembly and roof

•Door

•Vent (if applicable)

•Glazing

• All illustrations are based on viewing the parts from the inside of the greenhouse, except where stated.

• Assemble the greenhouse loosely where possible and tighten when all in place so that minor adjustments can be
made. Note that some nuts will need to be tightened to keep them in place.

• Tighten all nuts carefully, being sure not to miss any. Check the frame is square and using a spirit level to check
that it is upright.
