Bloomcabin Oasis Pyramid Greenhouse
Pyramid greenhouse with a striking roof shape, generous central height and a versatile interior
The Bloomcabin Oasis Pyramid Greenhouse combines protected plant growing with distinctive garden design. Its roof planes rise symmetrically towards the centre, recalling a compact glass pavilion, while the interior remains practical for propagation, care and harvesting. This makes Oasis equally effective near the house or among beds, paths and shrubs.
The current range includes square and rectangular footprints. Several glazing, frame-colour and door-layout configurations are available. These decisions shape more than the appearance: they also determine usable standing areas, walkways, light conditions and everyday greenhouse work. Construction, gutter and aluminium-base details are listed in the technical overview.
When planning the position, consider the sun path, views from the house, ground conditions and access together. Effective summer ventilation, a short route to water and sufficient clear space in front of the door are also important. A scale drawing helps select the right footprint and identify conflicts with paths, beds or existing drainage lines early. Discover the Oasis Pyramid Greenhouse at Bloomcabin for South Africa.
The pyramid shape in the garden
What distinguishes Oasis from a greenhouse with a continuous ridge
The roof planes rise from several sides to one shared apex, giving Oasis its unmistakable form.
Its roofline remains striking from different viewpoints, making it particularly suitable for visible garden areas.
Inside, the concentrated roof geometry draws attention towards the centre rather than emphasising a pronounced longitudinal axis.
Distinctive silhouette
The clearly structured form suits both formal, linear gardens and more traditionally planted settings.
High centre
More height in the centre than at the sides
Flexible glazing
Polycarbonate or toughened safety glass
Wide colour choice
RAL colours for coordinated house and garden styling
Light from several roof planes
How the pyramid shape changes daylight through the day
The sloping roof planes receive daylight from changing directions. Interior brightness therefore varies more with the sun’s position than beneath one continuous roof slope. For planting, this means that not every zone receives equal light throughout the day. Before fitting out the greenhouse, observe which areas are temporarily shaded by the house, trees or hedges in the morning, at midday and late afternoon.
Toughened clear glass creates a direct visual link between plants and garden: outlines, flowers and leaf textures remain clearly visible. Polycarbonate diffuses light differently and offers less direct visibility. The choice should therefore consider not only exterior appearance, but also the intended crops, desired privacy and how visible shelves, pots and work materials should be from outside.
For a sound choice, assess the actual site rather than an idealised sunny situation. North-facing areas, reflective walls and sheltered courtyards can bring substantial heat on clear days. Partly shaded positions, by contrast, require careful placement of plants. Assess glazing together with the ventilation routine, possible shading and the planned interior layout.
Choosing a site to suit the pyramid form
These four points matter most when selecting the site
Because Oasis is highly visible in the garden, good growing conditions and an attractive position should work together.
01
View from the house
First mark the planned footprint in the garden. Then check how the roof apex looks from frequently used rooms, the patio and along important paths. A pleasing sightline is an advantage, but should not compromise light, access or plant growth.
02
Sun
Assess not only compass direction but the real pattern of light at different times of day. Deciduous trees change shade through the seasons, while buildings and evergreen hedges provide permanent screening. A suitable position therefore also depends on the plants you intend to grow.
03
Door side
Position the sliding door so soil, pots, harvest crates and watering equipment can be moved without tight turns. The route should remain easy to walk in wet weather. Leave enough clear space in front of the entrance for opening, setting down items and manoeuvring.
04
Rainwater
Record the gutter-outlet positions during measuring. Reserve room beside them for pipework or a suitable tank without obstructing access to the structure. Plan onward drainage together with the base construction and natural slope of the site.

Construction
Reinforced powder-coated aluminium
Equipment includes integrated gutters, a built-in aluminium base and different sliding-door options. When configuring, check which door solution suits the chosen wall width and how it works with the planned main walkway. Powder-coated profiles can be matched precisely to façades, window frames or other permanent garden elements through the RAL colour selection.
Making use of the height beneath the apex
The rising roof planes create especially generous usable height in the centre
Divide the footprint into height zones from the centre outwards. This allows climbing supports and taller crops where the roof geometry provides sufficient headroom, while lower areas remain available for compact plants or work surfaces.
Tomatoes, climbing crops or larger citrus plants can suit the central zones. Position containers and supports so fruit, shoots and watering points remain accessible from the main path and neighbouring crops are not permanently shaded.
For planning, use the available height at the actual plant position, not only the measurement at the roof apex. Draw tall crops with their container and support in a cross-section; usable clearance decreases towards the sides in line with the roof slope.
Combining cultivation and garden design
Four suitable ways to use it
01
Centrepiece of a kitchen garden
As the focal point of a kitchen garden, Oasis can create short links to raised beds, herb areas, compost and a water point. Heat-loving crops can be concentrated inside while tougher vegetables grow outdoors. Clear paths make it easier to move harvests, plant material and garden tools between the areas.
02
Area for tall crops
Climbers and larger containers can be arranged beneath the roof centre so their vertical growth is not restricted too early. Edge zones remain available for lower crops, propagation trays or work surfaces. Plant supports must be stable and should not project into door or ventilation areas.
03
Flowering plants behind glass
Flowering and textural plants can be composed behind clear glass into a garden display visible from outside. Presentation should not compromise care: spent blooms, watering points and the backs of containers must remain accessible. A stepped arrangement prevents large specimens from completely hiding smaller ones.
04
Flexible reserve space
A deliberately unoccupied zone makes it easier to switch between propagation, peak season and overwintering. It can temporarily hold young plants, harvest crates or additional containers. This keeps the greenhouse adaptable without constantly rebuilding permanent planting areas.
Ventilation, paths and seasonal planning
The Oasis layout should be able to change with the plant collection. Plan fixed elements only where they do not hinder operation of the door and roof vents or seasonal changes to the interior.
Ventilation and shading
On sunny days, temperatures behind glazing can rise quickly even when outdoor air still feels pleasant. Base ventilation and any shading on conditions inside the greenhouse rather than outdoor temperature alone. A bright position remains valuable, but permanent heavy shading would reduce the light needed for growth.
Roof vents allow warm air to escape from the upper area, while the sliding door supports the supply of fresh air. For effective air exchange, tall plants and supports must not block the openings. Regular checking is particularly important where weather changes markedly within one day. Before absences, establish how ventilation and watering will remain reliably managed.
Flexible shading can be adjusted to the sun’s position, growth stage and current occupancy. Fit and operate it so roof vents can work freely and no components rub against glazing or frames. A small seating area may need a different shade zone from light-hungry fruiting vegetables.
Working routes and layout
The main path should lead straight into the interior from the sliding door. Planting areas, shelves and controls must be accessible without reaching over delicate crops. At floor level, allow room for turning, setting down crates and working with a watering can or hose.
Before final placement, trial-fit shelves and planting tables with the intended pots or trays. Check the remaining aisle not only with an empty work surface, but also with overhanging plants and stored work crates.
Free-standing equipment must stand securely on the selected floor and must not project into walking areas. Check shelves and worktables when loaded with filled trays or pots. Give heavy containers a permanently accessible position from the start.
Seasonal changes
In spring, clear work surfaces are needed for seed trays, pricking out and gradually moving young plants on. Group different growth stages so watering and inspection remain manageable. Before planting larger crops permanently, decide which tables will later be removed or used elsewhere.
In summer, air movement, water supply and harvesting access take priority. Regularly guide vigorous shoots away from paths and ventilation zones. Watering is easier to organise when plants with similar needs stand together and valves or hose connections remain accessible without blocking the aisle.
In autumn, the layout can be changed to accommodate sensitive container plants. Before bringing them in, prevent diseased leaves, pests and unnecessarily damp materials entering the collection. Moveable equipment creates space but does not replace selection: only plants suited to the planned winter quarters in size and care needs should occupy valuable interior space.
Plants, containers and work surfaces
Arrange plants and work surfaces according to how often they need care, watering or moving. Sensitive young plants and regularly used tools belong in accessible zones; larger, permanently placed containers need stable standing space with clear access for care. This keeps the layout practical even when full of plants.
Beds and plant containers
Whether to grow directly in beds or in containers depends on the intended crops and desired flexibility. Fixed planting areas suit permanently planned crops, while pots and tubs can be rearranged more easily. Decide the division before fitting out, together with the main path and watering.
Plant containers need stable standing areas and controlled drainage. Place saucers, outlets and watering points so escaping water is quickly noticed and removed. Persistent dampness must not collect beneath containers or directly beside the aluminium base.
Layout is not determined by free floor area alone. Overhanging leaves, wide containers and open work crates require extra room. A clear separation between planting zones and the main path makes care, harvesting and cleaning easier throughout the season.
Caring for tall crops
Tomatoes, climbing plants and larger citrus plants need not only height but also sufficient side access for care. Shoots, leaves and fruit should remain reachable without pushing neighbouring plants aside. Consider eventual width when positioning young plants.
Check climbing supports, ties and stakes regularly so they do not constrict growing shoots. Plants that are frequently pinched out, pruned or harvested belong in easily accessible positions.
Lower crops can use edge zones provided they receive enough light there and are not hidden behind tall containers during watering.
Workstation for sowing and potting on
A compact planting table provides a dedicated work surface for sowing, pricking out and potting on. Choose its depth and position so the main path stays clear and containers stored underneath remain accessible.
The work surface should be easy to clean and offer enough room for trays, pots and the tools currently in use. Return unused materials afterwards to a dry, easily accessible place.
A movable table preserves interior flexibility and can be removed or repositioned when mature plants or overwintering containers need more space.
Watering and equipment
Arrange the water connection, hose route and tool storage as one connected work area. This avoids repeatedly crossing paths while watering and keeps controls visible. Gutters, frames and opening elements still need unobstructed access for inspection and cleaning.
Order in the work area
Keep small tools, tying materials and plant labels in a fixed, accessible place. Work surfaces stay clear and necessary items are quickly at hand.
Shelves, containers and garden tools should stand securely, not lean against glazing and not project into the main path. Frequently used equipment belongs within reach of the work area; rarely used items can be stored farther back if maintenance access remains clear.
Leave sufficient space between equipment and the structure for cleaning and visual checks. This also makes it easier to remove leaves, soil and plant debris.
Watering
Especially with larger versions, plan in advance where water will be drawn and distributed. The connection should be reachable without moving heavy containers. A hose guide or support helps prevent kinks and protects plants from damage. Keep water installations separate from electrical components; use a legally registered local electrical contractor for electrical work, inspection, testing and any applicable Certificate of Compliance.
Separate drip zones can supply crops with different needs more precisely. This is helpful, for example, when large containers stand beside shallower plant pots. Lines should remain visible enough to spot leaks while creating no trip hazards. Check drippers and outlets regularly, as dirt can cause uneven supply.
Place filters, valves and shut-off taps where they are accessible and escaping water cannot cause damage. Clear labelling makes operation easier where several zones are present. Before frost periods, check which water-carrying parts need draining or protection, following the guidance for the components used.
Maintenance
Regularly check glazing, gutters, sliding doors and roof vents for dirt, smooth operation and visible damage. Remove leaves from gutters and soil or small stones from door tracks before they impair drainage or operation.
Clean glazing and powder-coated profiles with material-suitable products and soft tools. Abrasive methods can damage surfaces and glazing.
Thorough cleaning before introducing new plant collections makes inspection easier and prevents old plant debris remaining in hard-to-reach areas.
Rainwater, flooring and size selection
Coordinate floor construction, rainwater use and size selection in a sensible sequence: first establish a load-bearing base and drainage, then position tank and pipe routes, and finally compare the footprint with the complete interior layout. This prevents fixed installations later conflicting with the door area or maintenance access.
Collecting rainwater
Integrated gutters can channel rainfall to a suitable tank for vegetable beds and container plants. Short, inspectable pipe routes simplify checking, while a closed or suitably covered tank limits contamination. Before use, check whether water condition and plant needs are compatible.
Tank sizing depends on roof area, local rainfall, available space and actual consumption. A very large container is not automatically the best solution if it blocks maintenance access or is difficult to clean. Position the draw-off point so watering cans can be filled or pipes connected without obstructing the main path.
A suitable overflow directs excess water away from the foundation in a controlled manner.
Flooring
A robust, slip-resistant interior floor makes watering, potting on and cleaning easier. It should provide secure footing with wet shoes and stably support movable tables or containers. Loose soil in the main path increases cleaning work and can enter the sliding-door track. Planting and circulation areas can therefore be finished differently.
Depending on use, stone paving, gravel or other suitable permeable surfaces may be appropriate.
The finished floor build-up must align with the door threshold and must not obstruct drainage.
Size selection
The right size depends on the intended number of plants, the dimensions of shelves and tables, required circulation room and possible seasonal changes. Comparing square metres alone can underestimate the space needed for wide tubs, overhanging leaves and open work crates. Also decide whether the room is exclusively for growing or partly for sitting.
A scale drawing using the actual outside dimensions of equipment is more informative than a rough area estimate. Draw in the door, main path, planting tables, water point and large containers. Then check that every zone remains accessible without moving other items. Include the expected width of mature plants as well.
When choosing between a square and rectangular footprint, decide whether the layout should be organised around a central zone or along an axis.
Foundation and installation
A level, stable base is essential for accurate assembly of the complete structure
The built-in aluminium base does not replace preparation of a flat, stable substructure. Its construction must suit the soil type, local frost conditions and intended drainage. Set outside dimensions and levels carefully before starting. The finished build must neither direct water towards the structure nor impede the sliding door through an unsuitable floor connection.
Because several roof planes meet above the centre, a precisely aligned, square base is particularly important for assembly. Check level and diagonals first, then assemble in the specified sequence. Store components and glazing securely during the work. Allow suitable access equipment and enough helpers for work at height.
The structure is designed for a wind speed of 30 m/s and a snow load of 210 kg/m². Proper anchoring and a base suited to the site are required. Before installation, ask the relevant municipality which project-specific requirements apply to the foundation, setbacks and approval.
Planning in four steps
1
Define the use
First decide which plants will live there permanently, what height they are likely to reach and whether a small seating area is wanted. This determines the required footprint, suitable work zones and sufficient reserve space for seasonal change.
2
Test the site
At the intended position, record when direct sun reaches the area and what shade is cast by buildings, hedges or deciduous trees. At the same time, check that access, the water route and views work with the chosen door side.
3
Choose equipment
Select the footprint, glazing, suitable sliding-door option and RAL frame colour as one coordinated configuration. Consider the view from the house as well as existing façade, window and garden colours.
4
Prepare the base
Clarify the ground, anchoring, drainage and rainwater routing before assembly. A precisely prepared base makes it easier to join the roof planes and avoids extensive corrections during installation.
Frequently asked questions
FAQ – Bloomcabin Oasis Pyramid Greenhouse
How can I check the footprint in the garden before ordering?
Mark out the outer outline of the chosen version at the proposed site. Then draw or set out the main path, planting tables, large containers and clear door area within it. This gives a better indication of whether paths and work areas will remain adequate once planted.
What should I consider when positioning the door?
The door should face the main garden route and allow soil, pots and harvest crates to be moved as directly as possible. Leave clear space in front for opening, setting down items and manoeuvring. The main greenhouse path should also connect without a bottleneck.
Which glazing provides an unobstructed view of the plants?
Toughened clear glass gives the clearest view of plants, containers and fittings. Polycarbonate diffuses light more strongly and appears more enclosed from outside. The choice therefore depends on how transparent the greenhouse should look and what light effect is desired for the intended crops.
Are double sliding doors possible?
Yes. Double sliding doors are possible on compatible wall sides from approximately 3.10 m wide. Before choosing, check that the wider entrance suits the planned garden path and interior arrangement.
How should a rainwater-tank overflow be planned?
The overflow should direct excess water away from the greenhouse substructure in a controlled manner. Position the tank and lines so gutters, glazing and maintenance areas remain accessible.
Does the built-in aluminium base replace a prepared substructure?
No. The integrated aluminium base requires a level, load-bearing and suitably drained substructure. Careful alignment is particularly important so sliding doors, frames and roof planes meeting in the centre can be assembled correctly.
Can plant growing be combined with a small seating area?
Yes, provided the chosen footprint still offers sufficient space after fitting out. A small bench or compact table should obstruct neither the main path nor plant care, and should be easy to move when seasonal space needs change.
Which warranty applies?
Bloomcabin provides a 12-year warranty on the greenhouse structure. The applicable warranty terms apply; please check their scope, requirements and exclusions before purchase.
