Introduction Thank you for purchasing your new Alton greenhouse. We recommend you familiarise yourself with the instructions and read all safety information before you commence assembly. HELPLINE: 0116 267 7091 Safety Warning Glass, aluminium and timber can potentially cause injury. Please ensure you wear protective goggles, gloves, headgear and suitable footwear when assembling and glazing the building.
Finally, and most importantly, choose a site where your Alton Greenhouse will look right so that it will complement your garden. We cannot emphasis how important it is to have a proper base for your Alton Greenhouse to be erected upon. It is essential that the BASE IS FLAT, LEVEL AND SQUARE AS WELL AS BEING SUBSTANTIAL enough to take the weight of the greenhouse including its 3mm glass.

Base Dimensions Recommended 3’ X 2’ Slab (2” thick) (910mm X 610mm) 2” thickness (50mm) Slab Base Size (Recommended) Note: The base should always be larger than 5 : 1 your building. Note: If a membrane is used this may hinder drainage.
Overview To build your new greenhouse you will need the following tools: Spirit Level Pencil PZ2 Screwdriver Bit Cordless Screwdriver (2 would be ideal, 1 to drill and 1 to screw) 4mm Drill Bit 7mm Masonry Bit Hammer Drill Hammer Wooden/Rubber Mallet Tall step ladders x 2 Tape Measure...
Overview You can build the sides and gables flat on the ground and then with help or using a prop position the first one ready for installation. You then work your way around the greenhouse connecting each section. Once you have completed the gables and sides you can install the ridge and the roof. Glazing the structure is very simple but be very careful of the edges of the glass as the panes will break into tiny peaces if you catch an edge on a hard surface such as concrete.
Base Assembly Diagram 1 Lay out your aluminium base sections as the diagram shows. Use the twist-in crop head bolts in the bolt channels for attaching the base brackets (D174M), EV0311M diagram 1. The base brackets should always be positioned either side of the door, in the corners, in the middle of the end gables and equally spaced down the side.
Rear Assembly To start building your greenhouse begin by laying out the components for your rear side flat on the ground like the diagram below. Use the tables below to identify your building length and the components with the part numbers and sizes. First of all drill pilot holes through the bottom of each mortise on the cill section (e.g.EV0018) (diagram 2, page 10).
Rear Assembly Internal Pilot hole, it is easiest to drill Diagram 2 down through the middle of the Make sure the side bars are pushed all the mortise to make way in, you may find they need a light tap sure you get the with a wooden mallet or something similar.

Frame Assembly Before you position your sections onto the aluminium base you should drill the pilot holes in the bottom of the end gable side corner bars (EV0502 / EV0503) shown in diagram 28. The position of these holes should be about 19mm from the side face and 30mm measured from the bottom end of the bar.
Frame Assembly External Diagram 27 Keep faces flush Diagram 28 Make sure the side corner bar is located correctly and the front face is flush with the end of the eaves bar, mark out the pilot hole positions shown in diagrams 29 and 30. Diagrams 31 and 32 on the next page show the direction the holes should be drilled in.
Page 24
Frame Assembly Before fixing this corner make sure the inside Diagram 31 faces are all flush (diagram 31). When you are happy that the purling is located correctly (it is normal that the purling is set back slightly from the glass rebate on the front of the building) start by inserting the 80mm screw through the side of the eaves bar into the tenon on the end of the purling.
Page 25
Frame Assembly With help or using props for extra support, position the other end gable on to the base and repeat the steps from page 22 to 24. It is best NOT to fix this gable to the aluminium base at this point as you will want some adjustment when attaching the porch return side sections, but keep this supported at all times.

Page 31
Roof Assembly Now the ridge is in place you can install the roof bars. Slot the bars into the ridge first, the tenon may be a little tight so this might require a tap with a wood or rubber mallet. Once this has located correctly locate the bottom of the bar with the trench in the eaves bar/s.
Page 32
Roof Assembly With all the roof bars in place drill pilot holes vertically down through the roof bars, refer to diagram 30 (page 23) for the location of this hole. Make sure the roof bars are tight in to the eaves bar on the inside of the building and fix with 100mm screws (diagrams 45 and 46).
Page 33
Before you begin construction of the porch roof you Roof Assembly firstly need to check that your building is square and level, are the internal diagonal measurements equal? With so many precision components meeting from different directions you need to take time now to aid construction throughout the rest of the build.
Page 34
Your roof hip porch bars (EV0788) can now each be lowered Roof Assembly into place (pointed end towards the porch ridge) and secured with two 25mm csk screws at the top (diagram 49) and one at the bottom (diagram 50). Bottom view On each hip (EV0788) you will notice a notched out section on the underside face.

You need to decide where in the building you are having your Glazing (part 1) louvers. Below is an example of how it might be fitted. The louvre can replace any of the 610 x 916 panes, but make sure the handle operates and that there is no interference with the glass in the location that you choose.
Internal Louvre Glazing If you haven’t already done so you could now install the louvre glass (diagram 67). Make sure the tabs on the glass retainers are pinched slightly so they hold the glass tight. Standing on the inside of the building slot the first louvre slat in until it hits the bottom tab of the retainer.
