Elegant wall-mounted pyramid greenhouse

Custom wall base

Choose brick, natural stone, concrete or render to suit house and garden

Distinctive pyramid roof

Roof apex approximately 2.64–2.69 m, depending on footprint

Flexible glazing

Polycarbonate or 4 mm toughened safety glass

RAL colour choice

Match the frame colour to masonry and façade

Accurate footprint

Transfer the confirmed external dimensions to the site and check right angles and diagonals. Mark the door side, nearby paths, beds and drainage areas at the same time. This lets you check space and connections before excavation begins.

Door opening

Allow a clear, straight circulation area in front of the door. A wheelbarrow, plant pots and working materials must move in and out comfortably; side shelving or beds must not restrict either the opening or sliding area of the door.

Corners and connections

Plan corners, door reveals and wall coping continuously, so projecting edges do not obstruct installation or later cleaning.

Drainage

When setting out, check where rainwater flows across the property. Position the door side, adjacent paving and any possible water store so the base does not sit in a hollow and maintenance routes remain clear.

Square and extended footprints

Roof apex approx. 2.69 m; wall height approx. 1.93 m; door height approx. 1.85 m

Polycarbonate or 4 mm toughened safety glass

Powder-coated aluminium frame with sliding doors, integrated gutters and a precisely planned connection to the site-built wall base. The structure is designed for a wind speed of 30 m/s and a snow load of 210 kg/m². A suitable load-bearing substructure and professional installation are required; foundations and masonry must be designed for the particular site.

Brick, natural stone, render or exposed concrete

When choosing, consider how easily visible surfaces can be cleaned and repaired if necessary. Workmanship around door reveals, corners and wall copings should suit the chosen material, so these highly visible areas continue to look tidy over time.

Several visible edges meet at external corners and door reveals. Consistent joint lines, neatly finished copings and coordinated paving junctions are particularly important here. Treat these areas as design focal points.

The levels and lines of neighbouring paths and beds affect how prominent the base appears. Continuous paving edges and clearly defined planting areas frame the structure; deliberate spacing helps masonry and frame read as one architectural composition.

Door opening and floor junction

The masonry opening must match the confirmed sliding door exactly. Set the width, height, side wall junctions and position in the frame before work begins. For double sliding doors, first confirm that the wall width is compatible with the chosen model. Widening later can damage the bond, finish and floor connection.

The internal floor, threshold and outside path should meet without unexpected changes of level. The relevant dimension is the finished build-up, including base course and surface. Any structurally necessary threshold must be considered from the outset. Straight, sufficiently wide access is especially useful for heavy pots or a wheelbarrow.

At the doorway, finish joints, edges and paving connections so no unevenness projects into the sliding area. Fixed fittings should remain sufficiently clear of the door track.

Internal floor and usable area

A robust, easy-care internal floor makes watering, potting and cleaning easier. Materials, substructure and joints must suit regularly damp use and must not encourage uncontrolled pooling. Loose soil is easier to remove from a continuous surface than from inaccessible voids. Smooth finishes should still provide secure footing with wet shoes.

Stone, paving or other suitable surfaces can be coordinated visually with the wall base. Do not fill the usable area entirely with fixed fittings: a clear central zone makes it easier to turn with pots, clean the inside glazing and reach beneath the roof. For direct ground planting, define growing areas and firm paths clearly from the start.

Place frequently used work areas close to the door, water connection and material storage where possible. This shortens routes for potting and watering without permanently occupying the clear centre.

Frost and foundation

The low wall requires a load-bearing substructure suited to soil conditions and local frost depth. Fill, slopes, clay soils or previous construction can affect the foundation. The solution must therefore be designed for the individual property; generic approaches are not enough.

Movement from frost or uneven settlement can alter the level bearing surface for the aluminium structure. Plan foundation and wall as connected elements. Where ground conditions are uncertain, have the foundation assessed by a qualified professional before permanent masonry is built.

When planning the foundation, also allow for the eventual levels of ground, paths and beds so connections around the base can be completed as intended.

Rainwater

Integrated gutters direct rainwater away from the wall base. Their outlets must remain accessible and must not disappear behind dense planting or fixed fittings. In the external plan, decide whether water will be diverted, collected or led to suitable drainage. Short, accessible pipe runs make cleaning easier.

A rain barrel or suitable tank can make collected water available for plant watering. The container needs a stable location without blocking maintenance access. A lid keeps debris out, while a planned overflow prevents a full tank from spilling directly at the base or door. Follow the relevant container instructions for frost periods.

Overflowing water must not collect against masonry or in lower paved areas. A controlled outlet protects adjoining components.

Tall plants beneath the roof

Climbers and larger specimens can use the high centre of the pyramid roof. Plan supports early, without using the frame, vents or glazing as support. Freestanding or purpose-designed climbing structures guide growth and can be removed when crops change.

A scale interior sketch shows where mature plants have enough height without narrowing pathways. Include pots, saucers, plant benches and supports. Compact crops usually suit edge areas better, while upright plants can use the taller space in the middle.

Place tall plants so their pots remain reachable for turning, watering and removal. Available height alone does not determine whether an interior location is practical.

Summer ventilation

The high pyramid roof provides generous air volume but does not prevent overheating on sunny days. Warm air must be able to escape through the intended openings while cooler air enters through the door and other ventilation routes. When and for how long to ventilate depends on weather and plant stock.

Roof vents and the sliding door should allow unobstructed air exchange. Climbing shoots, tall plants and fittings must not block these routes. Leave sufficient space between shelving and transparent surfaces for air circulation and for condensation or plant debris to remain visible and reachable.

In strong sunshine, temporary shading can protect sensitive plants and make the space more comfortable. It must not interfere with vents, sliding doors or frames. An adjustable solution is more practical than permanent shading because light requirements vary with season and planting.

Who is a greenhouse on a wall base suitable for?

This version suits a long-term fixed site where the base is intended as a deliberate part of the garden design. If the greenhouse is likely to be moved later, give particular weight to the permanently built substructure when deciding.

Mark the planned top level of the base at the site as a trial. Before construction, this helps show which garden areas will be screened, how proportions look from seating height and whether the enclosed zone suits the intended use.

The project includes not only the greenhouse, but also planning and constructing its foundation, masonry and floor connections. The base version therefore suits projects where these trades can be coordinated in timing and expertise.

Electricity and water

Prepare water supply, irrigation and lighting before the wall and floor are finished. First decide which connections are actually required and where they will be convenient to use. A tap behind a raised bed or a socket in a narrow doorway would be impractical later. Service runs must not interrupt the greenhouse bearing surface.

Conduits permit concealed service runs and make later additions easier without opening finished masonry. Their ends should be marked, accessible and protected from soil or water. Record their route and purpose on a sketch so concealed services are not damaged during later drilling or fixing work.

Have water services installed by an appropriately qualified trade, and have a licensed electrical worker assess and complete the electrical installation for the site. Electrical components must suit their location and be protected from damage during watering or cleaning. Extension leads across walkways are not a suitable permanent solution. Water lines should be isolatable and accessible for seasonal use.

Shelves, benches and raised beds

Work tables, shelving and raised planting areas can be arranged neatly along the wall base. Match their dimensions to the door opening, pathways and watering reach. Over-deep surfaces make rear pots and cleaning difficult; work height depends on whether you will sow, pot on or simply place plants there.

Avoid creating a permanently damp, inaccessible zone between furniture and the wall. Open bases make inspection and cleaning easier. Heavy supplies can sit on stable lower levels, while frequently needed tools can be stored within easy reach.

Tall or heavily loaded fittings must stand securely on the intended floor and must not lean against glazing or frames. Position them so the area behind can still be inspected and cleaned.

Care of frame, glazing and masonry

Clean from top to bottom so loosened deposits do not fall on surfaces already cleaned. Keep gutter outlets clear while working and then remove debris from the wall coping and floor connections as well. Follow the care instructions for each material.

Keep the sliding-door track free of soil, leaves and plant debris so the door can operate without obstruction.

Check wall joints, surfaces and transitions regularly for cracks, loose material or persistently damp areas. Use gentle cleaning methods that do not damage coating, glazing or joints. Remove deposits from gutters before they obstruct water flow.

Use through the year

In spring, the interior provides space for sowing and young plants. Clean tables and shelves before moving plants in, so old plant debris does not remain in inaccessible corners. Even with low outdoor temperatures, clear days can warm the space quickly; ventilation and water supply should therefore already be working.

In summer, many crops require more space than in spring. Harvesting, tying in and pruning should be possible without continually placing pots in the doorway. Keep a small work zone clear for these regular tasks and remove plant debris promptly.

In autumn, sensitive container plants often need more room. Before moving them in, check light requirements, plant condition and possible pest infestation. Movable containers and shelves make rearrangement easier. At the same time, inspect gutters, door tracks and glazing before wet weather makes the work harder.

Pyramid greenhouse on a wall base

A fully freestanding greenhouse on a low wall built on site. This version suits projects where base material, garden paths and frame colour are deliberately coordinated and where the additional work for foundations and dimensionally accurate masonry has been allowed for.

Standard pyramid greenhouse

In this version, aluminium profiles and glazing extend to the lower area. It therefore appears lighter and more transparent; an individually built masonry base is not included. Choose the base version instead if you want an enclosed lower zone or a visual continuation of existing masonry materials.

Lean-to greenhouse

A lean-to greenhouse uses an existing building wall and has a single-sided roof form. Its location, connection and light are influenced by that wall. It is not another name for the freestanding pyramid model on a wall base, but a different greenhouse type.

Document the configuration

Record the confirmed size, glazing, frame colour and door position in one shared plan revision. Give that revision to everyone involved; older drawings must not replace it for foundation, masonry or installation.

Assign responsibilities

Decide who will design, complete and inspect the foundation, masonry, floor, drainage and any services. Also identify the interfaces with greenhouse installation, so responsibility at the wall top, door opening and gutter outlets is clear.

Confirm interfaces

Before building starts, check together that levels, connections, service routes and access match the same plan revision. Include existing underground services. Resolve open points before excavation or masonry work creates irreversible constraints.

Prepare installation

After acceptance of the finished base, coordinate delivery, storage and the installation sequence. Build the frame according to the installation instructions; keep glazing and roof components protected until fitting and handle them carefully.
