Façade and installation situation

Solid masonry, brick, rendered surfaces and insulated façade systems each require suitable connection and fixing solutions. With external insulation especially, the visible surface must not be mistaken for a load-bearing substrate. Have the wall construction and intended mounting zone professionally assessed before foundation work begins or a configuration is finalised.

Record windows, doors, sills, exterior lights, sockets, vents, services and downpipes on a dimensioned drawing. Include components that must be opened, cleaned or replaced later. A scaled sketch prevents the roof edge, frame or door area from restricting existing functions and shows the realistic usable wall length.

Because a lean-to greenhouse stands directly against the architecture, assess its design from normal viewpoints: the garden path, patio and adjoining rooms. The selected RAL colour can echo window frames or metalwork, while Accoya provides a deliberate natural counterpoint. Joint patterns, paving direction and adjacent planting also shape the final overall effect.

Condition of the mounting wall

The mounting zone must be sufficiently level, stable and free of loose layers along the entire connection line. Local projections or recesses can complicate a clean wall junction and should not first be discovered during installation. Also check that the work area remains accessible from outside, so frame parts can be aligned and fixing points installed safely.

Inspect the proposed area for cracks, flaking render, moisture marks and older repairs. Behind cladding or insulation, there may be layers requiring special consideration when planning fixings. Confirm the route of concealed electrical, water or other service lines before drilling. Opening windows and shutters must remain fully operable.

Necessary repairs to the wall or plinth should be completed before greenhouse installation. This also applies to required repointing or professionally creating a robust connection area. Agree how the transition between the structure and building will be finished. A carefully prepared wall simplifies installation and reduces later work in awkward areas behind frames or planting.

Watering inside

A water point nearby simplifies plant care without needing to run a hose permanently through the doorway. Plan the route from the connection to planting areas so that neither the sliding door nor passage is blocked. If you mainly use a watering can, allow for a stable set-down point and a short, trip-free route to the greenhouse.

For drip irrigation, divide the layout clearly into planting zones so crops with different needs are not necessarily watered together. Lines can run along shelving or beds, but should remain visibly accessible for inspection and cleaning. Keep connections off walkways and away from moving door parts. The system should be easy to drain before extended periods of non-use.

If you wish to collect gutter water for watering, position the container so it remains accessible without narrowing greenhouse access. Coordinate it with the gutter outlet and watering routes. Its overflow needs a controlled discharge that keeps water away from the façade and foundation.

Summer heat on sunny walls

On a strongly sunlit wall, direct radiation, heated façade surfaces and the enclosed greenhouse shell combine. Heat can build faster than the outside temperature suggests. Do not position especially heat-sensitive plants immediately against the hottest rear-wall zone. Clear air routes and a ventilation routine suited to the time of day help avoid pronounced heat build-up.

Roof vents release rising warm air, while the sliding door can admit additional air at floor level. Both types of opening should be reachable without moving heavy containers. On warm days, do not wait until evening to check whether ventilation is needed. If you are often away during the day, consider the required operation realistically when selecting and placing plants.

Temporary shading can protect sensitive leaves, young plants and newly repotted crops during periods of intense sunshine. Fit it so roof vents still operate freely and glazing remains reachable without unsafe makeshift solutions. Permanent heavy shade is not suitable for every use. The right approach is seasonal and responds to the plants and actual light conditions.

Façade, frame colour and Accoya

Frame, Accoya elements and glazing work alongside façade colour, window divisions, gutters and patio materials. Compare colour samples directly at the planned site rather than only on a screen. The same RAL shade can appear different beside render, brick or timber as daylight changes. Untreated Accoya adds a natural accent.

A restrained frame colour can continue existing window profiles, while a deliberate contrast makes the structure more prominent. Consider the view from indoors too: the greenhouse grid may be clearly visible from a kitchen or living room. A calmer colour combination often suits patterned paving, while the frame can stand out more against uniform render or neatly articulated brickwork.

Untreated Accoya gradually changes appearance under weather exposure. Do not therefore match adjoining timber solely to its initial colour. Aluminium and glass remain the clear visual framework.

Floor and threshold

The finished internal floor needs a durable, level, easy-clean surface. Its height must work with the integrated aluminium base and sliding-door area so no unexpected trip edge is created. Consider future plant containers, worktables and possible floor finishes when setting the level. Later layers must not impair door operation.

A floor of paving, slabs, gravel or another suitable material should drain watering and cleaning water in a controlled way while remaining level and slip-resistant. A fall must not leave tables uneven or direct water towards the building. Also check the transition to the patio, where the interior, door threshold and outside path meet and must be planned as one detail.

Mark the intended finished floor level on the wall before work begins. This reference line lets you coordinate foundation, base, threshold and adjoining paving. Include the opening and movement area of the sliding door. Establishing levels early prevents later paving work from narrowing access or leaving water at an unsuitable edge.

Drainage at the building

The greenhouse roof drains rainwater immediately beside the house, where it should not run uncontrolled onto the plinth or patio finish. Plan the full route from integrated gutter to the intended discharge point. Include splashback and the building’s existing drainage routes.

Existing downpipes must not be concealed or made inaccessible for maintenance. If the greenhouse gutter, house drainage and surface fall lie close together, separate their functions clearly or coordinate them professionally. Allow enough room to clean outlets. Leaves, plant debris and deposits must be removable without dismantling shelving or moving sensitive crops.

After completion, check during rain that water actually flows in the intended direction. Puddles at the base, threshold or wall junction indicate that falls or drainage should be reviewed. Keep soil, mulch and plant containers away from drainage routes. This makes it easier to see whether connections stay dry and the solution works as use changes.

Airflow in summer

During summer, adjust ventilation to weather, plant height and humidity. A widely opened door does not always replace extraction through roof vents, as warm air collects high up. At the same time, a closed door restricts low-level incoming air. Observe leaf condition and possible condensation rather than ventilating only by a fixed time.

Do not place large containers, bags or furniture directly in front of the sliding door. Roof vents should also remain easily accessible throughout the season. Regularly remove soil, leaves and other obstructions from moving parts so openings can be adjusted quickly when weather changes.

Tall tomatoes, climbing plants or densely filled shelves can interrupt airflow between the entrance and roof. Arrange taller crops so they do not screen openings or protrude into door tracks during care. Supports need their own secure location and must not be fixed to vents or moving frame parts. Regular pruning also keeps care routes clear.

Access for cleaning and maintenance

Include cleaning and inspection when planning the interior. Inner and outer glazing surfaces, gutters, door tracks, frame connections and roof vents must remain accessible. The outside next to a boundary or side wall can quickly become a tight space. Before choosing a size, confirm that safe access for essential maintenance will remain available there.

Fixed worktops must not cover door tracks, drainage points or connections that need access. Heavy containers are best placed where they neither obstruct maintenance routes nor need moving for every cleaning task. Frequently changed propagation containers belong in easier-to-reach areas. This means less rearranging when components need inspection or cleaning.

Keep sufficient space around important components for inspection and cleaning at all times. Empty pots and seasonal supplies do not belong in these zones. Plan a suitable standing position for work near the roof. Shelves, containers and load-bearing or moving frame parts are not steps or storage surfaces.

Short routes to the kitchen garden

Near a kitchen or patio, place herbs and frequently harvested crops in the front, easy-to-reach area. Plants needing less frequent care can stand further back if they receive enough light and air. The short distance to the house helps only when the route is not made awkward by furniture, steps or stored garden equipment.

Link daily checks to a few regular actions: look over plants, check moisture, adjust openings and take ripe produce with you. Changes are noticed early without requiring extensive work each time. Water according to each crop’s needs rather than treating all containers to the same routine.

Access must still work while carrying a watering can, plant container or harvest basket. Check usable passage width with the intended layout in place. Loose hoses, projecting supports and low shelves quickly become obstacles. A fixed set-down point near the entrance makes opening the sliding door easier and prevents items from being placed temporarily on the threshold.

Worktables and shelves

Work surfaces suit sowing, repotting and plant checks, while shelves keep smaller containers organised. Their depth should suit the user’s reach so rear pots remain accessible without constant rearranging. Leave space beneath or beside the worktable for cleaning. Wide shelves should neither take unnecessary light nor block air circulation along the glazing.

Set work height according to the most frequent task and the people using the greenhouse. For heavy containers, a lower, easy-to-reach resting place is often more practical than a tall shelf. Leave enough space above the work surface to lift plants and handle tools safely. Roof vents and adjacent glazed areas must not become unreachable because of fittings.

Mobile tables or light shelving make it easier to change between propagation, summer crops and sensitive container plants. Castors or feet need a level, load-bearing surface and must not enter the door tracks. If useful, mark permanent clear zones for passage and vent operation. The layout can then change seasonally without rebuilding the entire interior.

Seasonal routine

In the South African spring, bright work surfaces are useful for sowing, pricking out and repotting. During hotter months, air exchange, crop-appropriate watering and regular harvesting become priorities. As conditions cool, available space can hold selected sensitive container plants. Before winter, remove plant debris, clean gutters and door tracks, and inspect accessible components.

Store equipment not needed for the season outside the greenhouse where possible. Empty pots, packaging and unused supports otherwise occupy exactly the space needed when crops change. A small selection of regularly used tools may remain close at hand if kept dry and safely stored. This lets the space adapt to new plant heights and tasks without affecting routes or ventilation.

A flexible plan starts with a few permanent decisions: a clear main route, accessible door, reachable vents and unobstructed maintenance points. Within this framework, tables, containers and mobile shelving can be regrouped by season. Do not use the building wall for extra fixings without checking; every hole or load must suit the wall construction and greenhouse connection.
