Introduction Thank you for purchasing your new Alton building. We recommend you familiarise yourself with the instructions and read all safety information before you commence assembly. This instruction manual is also available online at www.greenhousepeople.co.uk in the technical help section should you need to reprint it. Should you require any additional advice you can always call us on 01782 385409.
Choose a site where the building is relatively easy to get to and convenient to bring water to and possibly a supply of electricity. Finally, and most importantly, choose a site where your Alton building will look right so that it will compliment your garden.
Overview To build you new Fusion greenhouse you will need the following tools: Spirit Level Pozidrive No. 2 Screwdriver Bit Pencil Cordless Screwdriver (2 would be ideal, 1 to drill and 1 to screw) 4mm Drill Bit Hammer Hammer Drill Step ladders 7mm Masonry Bit There are 9 types of screws used in the construction of the workshop.
Base Assembly Diagram 1 With help stand the base sections on the shorter edge in the location you want your workshop, slide together making sure the top surface of the floor boards are flush. Fix with 60mm countersunk screws (diagram 2). Check page 7 opposite for the recommended layout of the base relevant to your building.

Side Assembly Diagram 12 Diagram 11 Before you place any of the panels remember remove the transit blocks from the bottom of the panels (diagram 12), once removed be careful not to damage the cladding. Position the first panel onto the base (diagram 13). Its best to start at the rear of the building with the large plain panel.
Page 10
Side Assembly Work your way around the building installing the panels as per the diagrams on page 8. When fixing the panels make sure you pull them together tightly (you can even clamp them if that’s easier) before fixing (diagram 17). On a straight jointed panel the internal surfaces should always be flush. Its also important that the tops of the panels are level/flush.
Door Installation Diagram 19 Diagram 18 Dia. 20 Dia. 19 Before you can install the door section you need to fit the door handle. Slide the spindle through the lock to give you the position of the handle on the door. Fix the handle with the 3.5 x 25mm countersunk screws supplied (diagram 20).

Door Installation Diagram 21 Slot the door panel into position and fix with 80mm countersunk screws, remember to drill pilot holes first. Diagram 22...
Fixing Down With all the panels in place you can now check everything is square and parallel. Do this by checking the internal diagonal measurement corner to corner are equal, also make sure the sides are in line. You can then fix the side panels to the floor. Drill pilot holes and fix with 40mm countersunk zinc plated screws (02-1816).
Gable Installation Now position the gable section (ABA0182) above the door. Line the Diagram 25 end of the bottom rail up with the outside of the softwood frame on the side panel (diagram 26). Make sure the internal surfaces Dia. 26 are flush before fixing.
Transom Window Installation Begin installing the transom windows by placing the first section up against the Diagram 29 front gable section. The end of the ABA0222 transom window should be flush with the softwood frame (diagram Dia. 30 30). ABA0183 Diagram 31 Internal Dia.

Transom Window Installation Place the next section alongside the first. Make sure the frames are flush with each other, drill a pilot hole and fix with an Diagram 33 80mm countersunk stainless steel screw (diagram 34). Dia. 34 Diagram 34 External Once all the transom window frames are connected you can fix down...
Ridge Installation Part No. Part Description AB0595 Framing Ridge Plate 6ft Long 1890mm AB0596 Framing Ridge Plate 8ft Long 2520mm Now fit the ridge plate on top of the transom AB0597 Framing Ridge Plate 10ft Long 3150mm windows. You can identify your specific ridge AB0598 Framing Ridge Plate 12ft Long 3780mm plate in the table opposite. Drill 2 pilot holes in each end of the ridge plate and fix with 80mm countersunk zinc plated screws (diagram 37). Next drill pilot holes through the notched sections of the ridge plate (diagram 38).
Eaves Plate Installation Diagram 40 External Next you can fit the eaves plate to the top of the side sections. Slot this in between the two gable sections. It should be flush with the softwood frame on the inside with the notches facing upwards (diagram 37).
Roof Frame Installation With the ridge plate and eaves plate now installed you can start fitting the roof rafters. These slot into the ridge and eaves plates, make sure the rafters are tight up to the ridge and likewise tight into the eaves before fixing.
Page 20
Roof Frame Installation With all the roof bars in place you can now fit the purlins. These slot into the notches in the roof rafters and the gable end sections (diagram 46). Drill pilot holes and fix with 60mm countersunk screws.
Gable Soffit Installation Now fit the gable soffit bars to the top of the gable sections. The ends should be flush with the outside edge of the ridge bar (diagram 49) and the end of the gable frame (diagram 48). Drill 4 evenly spaced pilot holes and fix in place with 60mm countersunk screws (diagram 47).
Roof Sheet Installation Now install the ply roof sheets, start by fitting the two sheets (AB0632) next to the gable ends (diagram 51). Make sure the top edge of the roof sheet is flush with the ridge plate and the end of the gable soffit bar (diagram 53).
Page 23
Roof Sheet Installation Fix the roof sheets with 1 inch countersunk zinc plated screws (02-1814). Keep the fixing close to the edge of the sheet to be sure to pick up the roof rafter below. You should also fix to the roof purlin in the middle of each roof sheet (diagram 54).
Rear Fascia Installation Now the roof sheets are all fixed in place you can fit the rear fascia, slide this up tight to the underside of the ply roof sheets. Fix this in place with 60mm countersunk screws, position one at each end and then at every joint in the ply (diagram 56).
Trims & Cloaking Installation Diagram 59 External Next you can install all the trims and capping pieces. Start with the long corner cloaking, this should be fitted level with the cedar cladding at the bottom of the panel (diagram 59). The outer edge should also be flush with the side cladding.
Page 26
Trims & Cloaking Installation Now fit the top trim rail to the gable end, slot the top edge in first then roll the bottom in. Position these tight up to the corner cloakings you just installed (diagram 61). The mitred end should line up nicely with the corner of the softwood frame (diagram 62).
Page 27
Trims & Cloaking Installation Diagram 65 External When the gable trim rails are fitted you can install the trim rail at the eaves, again slot the top edge in first and rotate the bottom edge in until in position (diagram 65). Fix internally with 60mm screws.
Page 28
Trims & Cloaking Installation Diagram 68 External Next fit the shorter corner cloaking sections, this time you want to position these below the trim rails. Again these should be fitted flush with the cladding on the side panels (diagram 68). Fix with 50mm Pan head screws.
Page 29
Trims & Cloaking Installation Now the cloaking trims can be fitted to all the vertical joints in the panels (diagram 70). You can also fit these to the joint between the corner cloaking and the side panels (diagram 71). Fix in place with 40mm Pan head screws, the screw is located centrally to the joint.
Page 30
Trims & Cloaking Installation External Diagram 73 The weather strips are fitted directly above the large side windows (diagram 73). On the inside of the building drill 3 pilot holes no more than 10mm below the joint in the panel, shown by the arrows below (diagram 74).
Greenhouse Installation Now follow the main greenhouse instructions, head straight to page 5. Familiarise yourself with the process of installation in the overview. Once you have read this you can begin to install the aluminium base (page 7). When you get to page 20 (section 7) you can ignore the instruction to stick the foam strip to the ridge and wall bars.
Gutter Installation (Optional) If you have not opted for the workshop guttering system ignore this step and move onto the felting of the workshop roof. Begin fitting the guttering by fixing a gutter bracket above the cloaking trim at the end of the building (diagram 79).
Page 33
Gutter Installation (Optional) Diagram 81 External Now fit the gutter outlet to the building, the centerline of the downpipe should be in line with the centerline of the end cloaking trim (diagram 81). Fix the gutter outlet to the building with a 40mm Pan head screw.
Roof Felt Installation Before cutting the roof felt, measure the roof and add 160mm to that. You can then cut 3 strips at this length. The first section of roof felt should be fitted with an 80mm overhang along the bottom edge.
Page 35
Roof Felt Installation Now use the cedar ridge fascia to position the felt in-line with the roof purlins, DO NOT FIX THIS TO THE ROOF (diagram 85). Line it up with the lowest of the marks on the lower purlin, you made these earlier in the build on the soffit bars (diagram 50, page 21).
Page 36
Roof Felt Installation Again line the ridge fascia up with marks on the gable soffit bar, this time use the lower mark on the upper purlin (diagram 87). Lay the next length of roof felt on to the ridge and get it in to position. Fix down with clout nails and allow the excess to lay on the roof of the greenhouse (diagram 88).
Page 37
Roof Felt Installation Shape the roof felt down the face of the sub-fascia, fix with just a few clout nails to hold it in place. Diagram 89 Starting at the bottom, fold the corner in flat and fix with a clout nail (diagram 90b), then fold the middle section down and fix through the overlap.
Barge Board Installation With the felt folded over the gable ends and nailed down you can install the barge boards. These should be fitted flush with the top of the roof and eaves (diagram 92). Fix in place with 40mm Pan head screws.
Ridge Fascia Installation You can now fit the ridge fascia board, again this fits flush with the top of the roof and sits evenly spaced between the gable barge boards. Trim to size if needed. Return to the main greenhouse instruction on page 40, section 12 to install the roof vent to the greenhouse.
Work Bench Installation (Optional) Diagram 96 N.B. The workbench height is set at 900mm from the floor (diagram 96). you wish to install this at a lower position all you need to do is cut the work bench leg(s) to suite. Start by marking the internal frame on each vertical member at 900mm that will come into contact with the workbench.
Page 41
Work Bench Installation (Optional) Diagram 98 Fix the next section(s) in place in the same way, using the marks on the framework to acheive the correct position. Use two 60mm countersunk screws between sections. Once the sections are in place you can fit the workbench cover strips (diagram 99). Drill evenly spaced pilot holes and fix in place with 40mm countersunk zinc plated screws.
