A. No, this is very unlikely as all modern greenhouses are supplied with comprehensive detailed erecting instructions.
Just sit down with a cuppa and read them thoroughly before you start.

When you are ready to start building your greenhouse the first thing is to check that all the parts are there by ticking them off against the parts list provided.
In the unlikely event that something is missing or some glass is broken, contact your supplier, having the part number or glass size at hand, so that it can be replaced quickly and efficiently.

Lay out the steel or aluminium base (unless you are constructing onto a brick base or have purchased a model with an integral base) fix it together.
Place it in the position and mark the soil where the attached ground anchors touch it, after making sure you have got it square by measuring from corner to corner.
Now remove the base so that you can dig out the holes that the ground anchors will go into, after digging the holes replace the base, re-square it and make sure it is LEVEL.

From here on layout the main parts of the greenhouse on a level surface, making sure the ‘neoprene’ glazing strip has been inserted (if this is required for the make of greenhouse you have purchased) before you start to bolt it together.

When you have assembled both ends and the two sides you are ready to start assemble it, for this you will need some assistance to hold the sections while you bolt them together.
After bolting the ends and sides together fix the ridge bar and then the roof glazing bars to the ridge bar and to the eaves/gutter section.

Slide the roof vents and position.

Make sure the main structure is fixed to the base as per the instructions unless it has an integral base.

Fit the door to make sure it runs OK, even if you have to take it off again to get the glass in, you will at least know that everything is correct before you start glazing.

If the neoprene or mastic strip, which the glass lays on, is the type you fix after erecting the main structure then this is the time to fit it.

The next thing is to start glazing your greenhouse.

Place glass in all four corners of the roof but do not fix them,
NOW THIS NEXT BIT IS VERY IMPORTANT.
Make sure they lay in-between the glazing bars SQUARE, if they are not square then you have not got the greenhouse level and need to take another look at the levels.

Once you are happy with all this, continue glazing.
We start with the roof at the back and work towards the door, bringing both sides along at the same time.
Then glaze the sides and then the back leaving the front till last.
None of this is set in stone, other glaziers will probably say different; we have been doing this now for 40 years and have had no problems with this system.

Once you have the front end glazed, fit the door again and test it, if you have got all your level correct it should run and close OK.

It is now time to cement the ground anchors in, don’t make the concrete too runny and firm it in around the anchors leaving it just below ground level so you can cover it with some soil.

Lay some slabs down the centre to form a path, erect the staging, fit shelving and auto vent openers the that you purchased from Barretts Leisure when you ordered the greenhouse!

All the best and happy greenhouse gardening!
