GREENHOUSES

Backyard greenhouses in one 3D configurator. Pick a number, drag the footprint to size it and switch the options on the bar below. Each one is a buildable design: every stud, sheet, screw and hinge in the model is a real catalog item, so the priced bill of materials, the cut list and the assembly steps follow every change.

• 1 Gable Greenhouse -- A classic timber greenhouse under a 30-degree gable roof, glazed all round with 8 mm (5/16 in.) twinwall polycarbonate. It sits on a 4x6 base held down by ground screws -- no concrete -- over a gravel floor. A glazed, braced door in the front gable and roof vents under the ridge that open on their own as it warms up; switch on the knee wall to clad the bottom 60 cm (2 ft) in wood siding.
• 2 Lean-to Greenhouse -- A greenhouse against a house or garage wall, which keeps it warmer. Its own back wall stands on the ground screws, and a few angle brackets and a metal flashing tie it to the wall; one 20-degree slope of 8 mm (5/16 in.) twinwall polycarbonate runs down to the front wall. A glazed, braced door in the end wall by the house and roof vents under the top edge that open on their own as it warms up; switch on the knee wall to clad the bottom 60 cm (2 ft) in wood siding.
• 3 Hoop House -- A film tunnel over hoops of galvanized steel tube, each bent into a round arc on straight legs that are strapped to the same 4x6 base on ground screws, with a soil floor to plant straight into. Timber end walls with a braced door at the front, and the greenhouse film clamped in lock channel with wiggle wire; switch on the roll-up sides to roll the side curtains up under the hip boards for air.
• 4 A-frame Greenhouse -- Steep 60-degree slopes of 8 mm (5/16 in.) twinwall polycarbonate run from the ridge straight down to the base, so the roof is also the walls and sheds snow and rain with ease. Pairs of timber rafters stand on the same 4x6 base held down by ground screws over a gravel floor, closed by framed triangular end walls. A glazed, braced door in the front end wall and vents near the ridge that open on their own as it warms up.
• 5 Victorian Greenhouse -- The gable greenhouse with a Victorian bay: its back end is half an octagon, three glazed walls under a hipped roof whose hips meet at the end of the ridge. 8 mm (5/16 in.) twinwall polycarbonate over a wooden knee wall, on the same 4x6 base on ground screws with a gravel floor; a glazed, braced door in the front gable and roof vents that open on their own as it warms up.
• 6 Old Window Greenhouse -- The gable greenhouse with its walls made of old windows: set their size on the slider and the plan snaps to whole windows. Each sash sits on its own stud, screwed through its stiles, with battens over the joints and a sill board under them; panel siding below, 8 mm (5/16 in.) twinwall polycarbonate on the gable ends and the roof, on the same 4x6 base on ground screws with a gravel floor; a glazed, braced door in the front gable and roof vents that open on their own as it warms up.
• Step-by-step assembly for every model: each group of parts goes in, then the screws that fix it, with a cut list and a PDF to take outside.
• Stand the finished piece in your yard at full size in augmented reality, straight from your phone.
• Instant, itemized bill of materials with real supplier part numbers, in metric or imperial -- down to the last screw.
