Is it possible to site a greenhouse straight on top of the paving slabs on my patio? it is level.

yes use a small masonery bit with no 8 rawl plugs to match  and 2 inch no 8 wood screws . stat at the back put 3 holes and screws in the rear  premarking using the existing base holes , chalk will do this . drill and fix . then do the sides to the front , drill and screw the base down at both sides of the door jamb . sorted ,tighten all nuts in the house when constructed and then redo when the sun heats it up

Fantastic, Thank you for the quick reply!!!

I cannot wait now to get these last 3 days of work out of the way so I can have my 9 off and sort out the greenhouse and garden!

remember you cannot do this if you glaze it first .. use a square to make sure you set the frame square .. i did this with all my houses .with the fixing and the wieght of the glass the havent moved ,it is a 2 person job tho

you can square it with a tape measure just 3-4-5 each corner at a time.

 :?:  go on then explain please, 'cause I'm the king of not square

remember in school when you did triangles  :shock:
measure from the corner down one side 300mm and mark it
now measure down the other side from the same corner 400mm and mark it.
now measure from each mark (to form the triangle) and that will measure 500mm
try it

My mate used a lilo to measure his right angles for his greenhouse and it didn't go very well.

I have got a load of 18" x 18" slabs to use for by greenhouse floor. Is it ok to put these on the lip part of the metal base plate all the way round to secure my greenhouse??
There is a weedproof membrane down on level clay and I've got plenty of gravel.
Is there any other ways people can suggest to secure my greenhouse?

[muntjac]

if you got em gurder use em mate

put them on mortar mate and think about getting the water out as you dont want it water tight.
