Lean-To Greenhouse Limited edition

Accoya and aluminum

Untreated Accoya creates a warm, natural contrast with the aluminum, and its appearance will evolve with exposure. If you want to maintain a specific color or finish, select a treatment intended for Accoya and follow its application and maintenance instructions.

Range of sizes

Configurations for compact sites and extended wall runs

Polycarbonate or glass

Choose polycarbonate or 4 mm tempered safety glass

Integrated essentials

Roof vents, gutters, and a built-in aluminum base

Installation wall

Find the part of the wall where the greenhouse can be securely fastened rather than judging suitability from the visible exterior alone. Siding, stucco, brick veneer, and other finishes may conceal the supporting construction, so the attachment method must be chosen for the specific building.

Base and level

Prepare a stable, level foundation that supports the built-in aluminum base continuously and keeps the frame properly aligned. Confirm finished heights early so the paving, interior surface, and sliding-door threshold meet cleanly without holding water or creating an awkward step.

Entrance and circulation

Choose the sliding-door position based on how you will actually move through the space. Consider the route from the house, access to a hose or irrigation supply, turning room for larger pots, and whether the entrance would send garden traffic through dining furniture or a narrow planted border.

Rainwater

Decide where water from the integrated gutters will discharge or be collected before the foundation and surrounding surfaces are completed. Keep runoff away from the building connection and entrance, and avoid a layout that sends water across a primary walkway or into an area where it cannot drain effectively.

Lean-to wall greenhouse

Wall-mounted aluminum greenhouse with Accoya design details

12 sizes

Configurations to suit different lengths of usable wall

Polycarbonate or 4 mm tempered safety glass

Tempered safety glass provides clear views and a traditional glazed appearance. Polycarbonate diffuses light and has different weight, handling, and heat-retention characteristics. Base the choice on your plants, site exposure, desired visibility, cleaning access, and handling during installation.

Untreated decorative wood details

Supplied untreated, allowing the wood's appearance to change naturally with exposure

Single or double sliding doors

Double doors on compatible wall widths starting at about 122 in (310 cm)

Roof vents

Roof vents allow rising warm air to escape and support everyday temperature and humidity control. They work best when they can open fully and air can also enter through the doorway, so avoid blocking the airflow with tall crops, shelves, or hanging plants.

Integrated gutters and built-in aluminum base

Plan the gutter discharge and level support for the base before installation

The greenhouse is rated for winds up to 67 mph and a snow load of 43 lb/ft². Site exposure, foundation design, wall attachment, installation quality, and local requirements must still be considered for the individual project.

Wall construction

Brick veneer, stucco, siding, solid masonry, and other wall systems require different fastening and weatherproofing details. The visible finish does not confirm that the wall is suitable. Identify secure attachment points, concealed utilities, and the required exterior detailing before finalizing the greenhouse position.

Create a measured elevation of the proposed wall, recording windows, doors, vents, utility meters, hose connections, downspouts, exterior lights, paving edges, and roof projections. Then mark the door travel and required approach space on the site plan. This two-view check reveals vertical and ground-level conflicts that a simple width measurement can miss.

Check any local permit, setback, building, or attachment requirements that apply to the project. Coordinate permanent work—including the foundation, wall penetrations, drainage, electrical routes, and water lines—before assembly. Movable benches and plant staging can be arranged later, once the fixed structure and circulation space are established.

Wall condition

Inspect the proposed wall for deterioration, movement, moisture problems, uneven areas, or previous repairs that could affect installation. Correcting a wall issue after the greenhouse has been mounted is significantly more disruptive than resolving it beforehand. The attachment area must be suitable across the full required connection, not merely at a few convenient visible points.

Review how the greenhouse will meet the existing exterior envelope. Window trim, siding transitions, stucco edges, flashing, and drainage paths may all influence the final position. Preserve access to building components that require inspection or service, and do not cover an existing drainage defect with the new structure.

Create one site record containing photographs, measurements, openings, repairs, fixtures, and changes in wall finish so the proposed attachment area can be reviewed as a whole.

Water supply and irrigation

A location beside the house may provide convenient access to water, but plan the connection and hose route before installation. Position the water connection and any irrigation controls where they can be reached without leaning over plants, and keep loose hoses away from the doorway and sliding-door track.

Drip irrigation can deliver water directly to containers or growing areas and reduce repeated hose movement across a patio. Divide plants into sensible watering groups and retain a straightforward way to inspect the system. Automated watering does not eliminate the need to check soil moisture, emitters, drainage, and seasonal changes in plant demand.

Route collected roof water to an appropriate discharge point or a planned rain barrel without overloading the surrounding surface. A collection container needs a stable location and a managed overflow route. Keep connections accessible for clearing debris, and prevent standing water beside the built-in base or the home's wall.

Sunny south- and west-facing walls

A south- or west-facing wall may receive strong afternoon sun as well as reflected heat from light-colored walls or paving. Note how long the exposure lasts during the growing season and whether nearby trees or rooflines provide temporary shade. Place heat-sensitive plants away from the brightest areas when necessary.

Keep the roof vents and sliding doors easy to reach so you can respond promptly to changing conditions. During warm weather, adjust them with outdoor temperature, sunlight, wind, and plant moisture needs in mind rather than leaving them in one fixed position.

On sites with prolonged sun exposure, plan seasonal shade so ventilation is not the only way to protect sensitive plants from intense conditions.

Home exterior and frame color

Treat the frame color as part of the home's permanent exterior palette, especially when the greenhouse is visible from living areas or a frequently used patio.

Compare the RAL frame color with the home's window frames, roofing, masonry, painted trim, and permanent hardscape. Untreated Accoya adds another natural tone whose appearance may change with exposure. Reviewing the full combination at the installation site is more reliable than choosing the aluminum color by itself.

Prioritize compatibility with permanent exterior materials rather than trying to match movable patio furniture or seasonal decor.

Floor and threshold

Set the finished interior surface and exterior approach in relation to the sliding-door threshold before foundation work begins. The entrance should permit comfortable foot traffic and movement of supplies while allowing the door to operate fully. Where accessibility is important, include the approach slope, surface stability, and turning space in the initial plan.

Pavers, gravel, or another suitable interior finish should support the intended benches and containers without preventing drainage. Avoid low spots that retain water beneath work areas. If loose material is used, keep it from entering the sliding-door track, where accumulated grit can interfere with smooth operation and increase cleaning needs.

Detail the threshold and adjoining surfaces so runoff, gravel, and other loose material stay clear of the sliding-door track.

Cold-region foundations

Where freeze-thaw movement is a concern, the support must suit the local soil, drainage, and climate. Uneven movement can affect frame alignment, glazing fit, door operation, and the wall connection, so the foundation should be planned for the actual site rather than copied from an unrelated patio or garden project.

The built-in aluminum base does not replace the need for a stable, level supporting surface designed for the site.

Foundation design and installation must follow local soil conditions, building practices, and applicable codes.

Summer ventilation

Warm air rises inside the greenhouse, making the roof vents important during sunny periods. The sliding door can bring in air at a lower level when leaving it open is practical. Adjust the openings to suit the plants, weather, occupancy, and site security rather than relying on one fixed setting.

Position benches so the vent controls and full sliding-door opening remain easy to reach.

Place taller plants where they will not create a dense barrier between the door and roof vents. Leave open space around foliage as crops mature instead of filling every shelf. This makes airflow easier to manage and preserves access for inspection and pruning.

Maintenance access

Plan how each glazing panel, Accoya detail, gutter section, vent, and door track will be reached for routine care. A narrow inaccessible gap beside a fence or dense hedge can turn simple cleaning into a difficult task. Check overhead access as well, particularly where the greenhouse sits below an eave or near tree branches.

Keep permanent planters, built-in seating, and fixed outdoor kitchens outside the areas needed to service the greenhouse. Seasonal furniture can be moved, but heavy fixed features may prevent access to glazing, gutters, or upper frame sections. Include this clearance in the patio plan before the hardscape is finished.

Keep a usable access route to the roofline, outer glazing, and gutter outlets even after nearby planting matures.

Patio integration

Beside an outdoor dining or living area, the Accoya edition can create a natural visual link between the home and garden. Protect that appearance by planning storage for compost, empty pots, tools, and watering equipment. Everyday supplies should not block the entrance or dominate the patio view.

Walk through the full gardening routine: bringing in supplies, reaching the potting area, watering, harvesting, and removing waste. The shortest route is not always the most convenient if it crosses a dining area or causes congestion near a house door. Where possible, keep garden tasks separate from the main social walkway.

Test the patio layout with chairs occupied and pulled back from the table so the greenhouse route remains usable during normal outdoor use.

Interior benches

Arrange benches along the available sides while preserving a continuous central aisle. Test whether you can comfortably reach the back of each surface without leaning against the glazing. Leave access to door hardware and lower frame sections, with enough room to lift larger containers instead of dragging them through a narrow passage.

Select potting and display heights for the people who will use the greenhouse, the weight of expected containers, and the mature height of plants. A mixture of levels can accommodate propagation trays, compact crops, and taller specimens more effectively than one continuous shelf. Keep upper shelving clear of vent movement and routine cleaning areas.

Choose movable staging if you expect the layout to change as plants progress from propagation to mature crops.

Seasonal workflow

Seasonal priorities change: spring may require propagation space and frequent pot handling; summer shifts attention to airflow, watering, and harvest access; fall may call for reorganizing protected plants. Plan where unused trays, supports, and containers will go between tasks so each transition remains orderly and does not spill onto the patio.

Inventory seasonal supplies before sizing permanent storage, since empty containers, trays, and plant supports can occupy more room than expected.

Finalize the bench plan after selecting the greenhouse size and door configuration, since both affect usable floor and wall space.

Accoya Limited Edition

Choose the Accoya Limited Edition when the greenhouse will stand in a prominent location and natural wood detailing is important to the overall look. It retains the space-efficient wall-mounted format while offering a warmer appearance than an all-aluminum design.

Standard Lean-To

Choose the standard Lean-To when practical growing space beside the house is the main priority and Accoya detailing is not needed. It offers the same fundamental wall-mounted format, so the attachment, foundation, access, and drainage still require careful planning.

Freestanding greenhouse

Choose a freestanding greenhouse when a location away from the building works better or no suitable attachment wall is available. Its orientation and position can be planned independently, but it requires usable space around the structure and does not have the same direct visual connection to the home.

Check the wall and site

Prepare a dimensioned wall elevation, site photographs, the proposed foundation outline, and notes on drainage and utilities. Use this information to confirm that the selected configuration preserves access to building fixtures and greenhouse maintenance points.

Choose your configuration

Compare the available sizes, then select polycarbonate or tempered safety glass, the RAL frame color, and a compatible door arrangement. Check each choice against the measured wall and intended interior layout; a wider entrance may be more useful than maximizing bench length.

Prepare the foundation and drainage

Complete the stable, level support and establish the finished floor and threshold heights. Settle gutter discharge, surrounding drainage, utility routes, and the approach to the entrance before assembly begins. Leave enough working room around the site to handle the frame and glazing components.

Install, then organize the interior

Install the greenhouse according to the manufacturer's instructions and the site-specific attachment plan. Once the structure is complete and the vents, gutters, and doors operate correctly, add benches, irrigation, storage, and plants in stages. This keeps movable items out of the way during assembly and final adjustments.
