T Model greenhouse – a T-shaped orangery with clearly defined areas for plants and relaxing
The Bloomcabin T Model greenhouse is designed for gardens where growing plants and spending time under one roof should have distinct zones. The cross wing adds a versatile focal area to the long greenhouse body. Potting tables, crops and garden tools can remain in the work area, while the cross wing accommodates a dining table, seating or studio.
The range includes three configurations covering approximately 16.5 to 30.0 m². With an overall width of 310 cm, an approximate ridge height of 267 cm and a door height of 185 cm, it offers considerably more room than a compact hobby greenhouse.
When choosing, consider circulation space, sun exposure, foundations, drainage and required connections as well as available garden space. Decide early how the main body and cross wing will be used: a greenhouse mainly arranged for plants needs different paths, ventilation and water provision from an orangery used regularly for dining, reading or working. A well-considered layout makes later planning easier. Find out more from Bloomcabin.

How the T shape simplifies furnishing
In conventional rectangular greenhouses, plants, work areas and paths usually follow one long axis. On the T Model, the cross wing meets the main body to create a central transition. Both sections remain openly connected, yet the building shape allows them to be furnished differently. This is particularly useful when cultivation and relaxation need to share a glass-roofed space without a fixed internal wall.
The long main body can be arranged neatly with growing rows, propagation benches, shelving and taller plants. The wider cross wing has room for a table, freestanding seating, decorative containers or a creative workspace. Keep the transition between the two parts clear so watering cans, plant trays and chairs can move easily between the entrance, work area and seating.
The open connection preserves a generous sense of space and keeps plants visible from the relaxation area.

Set up the main body and cross wing for the intended use
Plant-growing area
The main body suits long worktables, propagation space and plant collections. Crops with similar care requirements can be grouped together, making watering and inspection easier. Sensitive or particularly decorative plants can be positioned where they are easy to see and reach.
Tall vegetables and climbing plants should not obstruct the central transition, doors or roof vents. Lower crops can stand nearer work areas, while heavy containers should be given a permanent, accessible position from the outset. This prevents mature plants from narrowing essential paths or ventilation openings later.
A small clear work or temporary storage area is useful at the transition to the cross wing. Harvest baskets, plant trays or watering equipment can stand there briefly without turning the dining or seating area into permanent storage. The passage itself should remain unobstructed.
Orangery and relaxation area
Furnish the cross wing according to its actual use. Leave sufficient space behind dining chairs to pull them out, locate a reading spot away from the main route, and provide an accessible work and storage surface for a studio. Freestanding furniture keeps the space flexible when more room is needed seasonally for plants or extra seating.
Larger containers can visually frame the relaxation area and look calmer than many small pots on the floor. Furniture, cushions and textiles should suit the temperature and humidity changes typical of a greenhouse.
Furniture and plant containers alone can define the zones visually. This keeps the arrangement adaptable as plant collections or use change during the year.
Aluminium frame, 4 mm safety glass and integrated gutters
The aluminium frame does not require regular protective painting. Clear glazing keeps plants and furnishings visible and reinforces the open effect of the T shape. When planning the interior, allow for roof slopes, frame profiles and movement space at sliding doors; position furniture and tall plants according to the genuinely usable internal area.
Depending on the selected version, single or double sliding doors are available. Their position affects access, daily routes and airflow between garden, plant area and cross wing. Roof vents allow warmed air to escape upwards. Integrated gutters direct rainfall from the roof, while the aluminium base frame creates the transition to the prepared foundation.
An optional chimney connection is available for a separately planned heating system. Before choosing heating, decide whether the aim is only to protect frost-sensitive plants or sometimes provide comfortable temperatures in the relaxation area. These aims create different requirements for heat distribution, controls, ventilation and energy demand. The heat source and its installation must be professionally planned independently of the chimney connection.

How can a T-shaped greenhouse be used?
Growing plants in the main body
Long tables, vegetables, herbs, young plants and collections can be arranged along the main body. A clear central path makes sowing, care and harvesting easier without disturbing use of the cross wing. Frequently used tools are better kept in compact, accessible storage beside the work area than on open surfaces in the central zone.
Welcoming guests and dining together
The cross wing can serve as a dining or conversation area while the long building section remains primarily for plants. Guests are therefore not seated among propagation trays and work equipment. The garden atmosphere remains, because both zones are openly connected and planting stays visible from the seating area.
Bright studio
Natural light suits painting, reading, photography or focused work. However, glare and heat build-up can change considerably as the sun moves. A movable worktable and flexible shading help adapt the space to the season and time of day without blocking roof vents or the main route.
Greenhouse for plant collections
Citrus plants, flowering plants, climbers and decorative containers can be arranged at different heights. Allow for their eventual size, weight and care access. Large pots are difficult to move later, so they should not stand in front of doors, drainage points or components that must remain accessible for cleaning and inspection.
Plan the T-shaped layout, sun path, future furnishings and required connections together. A site sketch showing compass directions, buildings, trees, access routes and existing services reveals early where shade falls, how rainwater can drain and whether the intended entrance is convenient in daily use.
Sunny south- and west-facing sites
On a sunny south- or west-facing site, the orangery can warm up quickly on clear days. The orientation of the main body is not the only consideration: because of the T shape, individual areas receive sun at different times or are temporarily shaded by the other wing. Observe the proposed site throughout the day and include nearby trees and buildings.
Roof vents and open doors provide effective air exchange only when air can flow freely through the interior. Tall plant rows, densely filled shelving and large cabinets can obstruct this route. Place lower crops near important airflow routes and leave adequate clearance between taller plants, doors and vents.
If the cross wing is mainly used for sitting or working, flexible shading is especially useful. It can be applied where needed and adjusted to the season and plant requirements. Roof vents must remain operable; shaded areas still need adequate air exchange.
Ground conditions and foundation
Setting out a T-shaped layout is more demanding than marking a simple rectangle. Angles, axes and levels must therefore be established carefully. The foundation must be professionally adapted to local ground conditions. On soft, made-up or unevenly load-bearing ground, settlement and level differences can later affect frame alignment, glass panels and the smooth operation of sliding doors.
A level, square and dimensionally accurate base makes correct installation of the aluminium base frame easier. Before assembly, check the external dimensions, the cross-wing position and the diagonals. Corrections become considerably more difficult once the glass structure is assembled. The planned internal floor must also suit the threshold height and intended drainage.
Rainfall and surface water must not collect at the foundation or entrances. Plan falls and outlets so water drains away from the structure. Around paved areas of the orangery, also consider runoff in heavy rain so no hollow forms directly beside the base frame.
Near a terrace or home
When positioned near the home, the cross wing can create an inviting link between house and garden. Check, however, how roof water, shade and frequently used routes affect the site. A short approach is convenient but should not pass through sensitive plant areas. Open sliding doors must not block important garden paths.
Position the entrance, table and larger plants so the orangery also looks harmonious from frequently used rooms and paths around the house.
Less decorative work and propagation areas can occupy the long main body, while the cross wing visible from the home remains calm and tidy.
First define the main route, work area and seating area. Plants, furniture and technical equipment can then be arranged so they do not obstruct one another in everyday use.
Plan heating for the intended use
A chimney connection is only the structural provision for a heating system planned separately. The appropriate solution depends on the plants to be protected, the period of use and desired temperatures. Heat source, clearances, flue route, combustion air and controls require professional assessment. Do not operate portable heaters unchecked between furniture and dense plant growth.
Frost protection for plants and comfortable temperatures for extended winter stays are different objectives. Frost protection requires a reliable minimum temperature; relaxation use also needs more even heat around the seating area. The extensively glazed interior responds more strongly to outside temperature and sunshine than an insulated living room. Define comfort and operating expectations before technical planning.
Controls and shut-off points should remain easy to reach without blocking work surfaces or the central passage.
Evening use
Consider evening lighting when positioning the table, work surfaces and connections.
Targeted light at the table is usually more practical than illuminating the entire greenhouse very brightly. Separate task lighting can be planned where plants are tended or repotted. Luminaires and installations must suit the moisture expected at the location. Cables must not create trip hazards or impede doors and vents.
Switches, sockets and cables can be integrated neatly before the finished floor is installed and arranged around later work and seating positions.
Clear routes in the T-shaped layout
The transition between the main body and cross wing is the key route in a T-shaped layout. An oversized table, large containers, shelving or stored equipment must not narrow it. If several people use the orangery, they should be able to pass each other while someone waters plants or sits at the table.
Consider not only an empty route but typical daily movements: chairs are pulled back, cabinet doors open and plant trays are carried at the side. Watering cans and bags need a temporary resting place. Sliding doors, ventilation mechanisms and maintenance points also need free access. A scale furniture sketch reveals such overlaps before heavy furniture and containers are placed.
Keep areas in front of sliding doors and at the junction of the building wings clear so the interior remains easy to access.
Plan fixed places for frequently needed tools, plant materials and cleaning equipment. This keeps work surfaces, doors and maintenance access clear even during intensive use.
Plan furniture to scale
Leave adequate room behind chairs and around seating even when every place is occupied. Draw the table and chairs both pushed in and pulled out. A studio also needs space for working movements and materials. Folding or easily moved furniture is useful if the cross wing changes seasonally between relaxation, overwintering plants and workspace.
The largest version is not automatically the right one; choose the configuration in which furniture, mature plants and desired circulation routes fit sensibly.
Also allow temporary clear work space for repotting, harvesting and plant care rather than filling every available area with furniture and containers.
Plan services early
Water, lighting, sockets and potential heating routes are best integrated before the foundation and floor are completed. First decide where watering, work and sitting will take place regularly. A water connection near the plant zone shortens trips with a hose or watering can; sockets at the seating area avoid temporary extension leads across paths. Shut-off points and switches should be accessible.
Fixed electrical installation work should be carried out by a REWS-authorised professional with the appropriate scope; heating-system work needs a suitably qualified professional and project-specific advice. They can assess routes, protective measures and whether components suit the location. Position and seal penetrations through the foundation or floor before assembly. Later drilling into assembled components can affect drainage, stability and component surfaces.
Record the position of concealed cables and penetrations on a plan so they can be identified clearly during later work.
Rainwater
Integrated gutters need a clear drainage route. Depending on local conditions, water can be directed to suitable infiltration or storage. Drainage pipes should remain accessible and not end where people regularly walk or work. Leaves, flower debris and other deposits must be removable without moving large furniture or heavy containers.
Collected rainwater can be used to irrigate many crops. A storage tank needs a reliable inlet, controlled overflow and a means of cleaning. The overflow must direct water away from the foundation. Even during a long absence, a full tank must not allow rainwater to run uncontrolled across paths or along the base.
Keep the storage tank outside main routes; a short distance to the plant zone makes daily use easier.
Maintenance access
Glass surfaces, roof vents, gutters, sliding doors and frame connections must remain accessible for cleaning and visual checks. Leave sufficient access along external walls and avoid permanent dense planting there. Work near the roof requires stable equipment and firm ground. Do not walk on glass, gutters or frame components not intended for this purpose.
Keep heavy furniture and large containers slightly away from glass and profiles indoors. This allows dirt and dead plant material to be removed and seals and connections to be checked. Keep sliding-door tracks free of soil, stones and leaves so the door panels run smoothly. Noticeable changes to fixings or glass should be professionally checked promptly.
Dirt and stored items are particularly noticeable at the junction between main body and cross wing. Include this central area in regular cleaning and visual inspection.
Keeping the T Model practical throughout the year
Roof vents help warm, humid air escape, while open sliding doors can admit fresh air at lower levels. In summer, ventilate early before large amounts of heat build up indoors. After watering, appropriate air exchange helps limit persistent leaf wetness and condensation. Shading reduces solar heat gain but does not replace ventilation.
The optional chimney connection allows a separately planned heating system to be incorporated. Nevertheless, the T Model remains a glazed garden structure without the insulation of a living space. On cooler days, areas near the glass can feel noticeably colder than the centre. Plants, furniture and equipment should suit changing conditions; seasonally adapted use is usually the more realistic approach.
Actual comfort results from the combination of outdoor weather, sunshine, plant quantity, ventilation, shading and, where applicable, heating. In spring the orangery may feel pleasant during the day but cool sharply at night. In high summer, removing heat is the priority, while autumn brings condensation and shorter days. A thermometer and regular observation help adjust ventilation and care routines.
Choose the right size from furniture, paths and growing space
Before choosing a size, draw the T-shaped layout with entrance, main route, tables, chairs, plant containers and work surfaces. Mark door zones, access to roof vents and areas that must remain clear for cleaning and care. Use actual furniture dimensions rather than rough estimates. This shows whether the cross wing fulfils its intended purpose and whether the main body retains enough continuous growing space.
Also check on the drawing whether mature plants could obstruct doors, vents, work areas or the view from the seating area.
Mark water, electricity and possible heating penetrations on the plan before the foundation and internal floor are completed.
Prepare the site, delivery route and assembly area carefully for the T Model
Before assembly begins, the prepared base must be fully completed and checked. The immediate surroundings are part of preparation too: the ground should be safe to walk on, components need a dry, orderly place to be set down, and adequate working space is required around all sides.
Check the complete route from the road to the assembly location. Narrow points, steps, gates, slopes, sensitive garden areas and low branches can make moving long or fragile components difficult. The site needs a level area where profiles and glass can be sorted by assembly stage. Because of the cross wing, several sides must be readily accessible; a tight construction area or dense boundary planting makes work harder.
The model is supplied as a kit, but its size and glazing make it a substantial assembly project. Read the assembly instructions fully and check component identification before work begins. Store glass on suitable supports and secure it against tipping. Working above head height, installing larger panes and aligning the structure require enough helpers, appropriate protective equipment and calm weather. If unsure, seek professional installation advice and availability.

Frequently asked questions about the T Model
What is a T Model?
The T Model is a greenhouse with a long main body and projecting cross wing. Their junction creates a natural focal point while the building sections remain connected without a fixed internal wall. This makes it easier to distinguish a productive growing zone from a relaxation or work area than in a purely rectangular greenhouse.
How should I divide the main body and cross wing?
Use the long main body for plant tables, propagation and work surfaces. The cross wing can hold a dining table, seating group or studio. Keep the junction between both building sections clear as a passage rather than using it as permanent storage.
How do I choose the right configuration?
Do not choose solely by the available plot area. Draw furniture, mature plants, work surfaces and clear routes to scale. The right version is the one in which both the main body and cross wing fulfil their intended purpose without obstructing doors or vents.
Where should large plant containers stand?
Give large containers a permanent, accessible position from the outset. They should not obstruct sliding doors, vents, drainage or maintenance points. Leaving some distance from glass and profiles also makes cleaning and inspection easier.
What matters for the T-shaped foundation?
The base must be level, dimensionally accurate and square. Before assembly, check external dimensions, diagonals and the precise cross-wing position. Include ground conditions and surface-water drainage in professional planning for the site.
Is the T Model suitable for entertaining guests?
Yes. The cross wing can be arranged as a dining area, seating area or studio. For comfortable use, plan furniture to scale, keep the central passage clear and consider shading and ventilation. The indoor climate remains that of a glazed greenhouse rather than an insulated living room.
Is roof ventilation included?
Yes. Roof vents are included and help warmed air escape. Together with appropriately opened sliding doors, they can promote effective air exchange. Plants, shelving and furniture should not block airflow routes or operation of the vents.
Can the greenhouse be heated?
Yes. An optional chimney connection is available for separately planned heating. The appropriate solution depends on desired frost protection, cultivated plants and intended length of stay. Selection, connection and operation require professional planning; the chimney connection alone is not a complete heating system.
How should I prepare for delivery?
Check the route from the road to the assembly site for gates, steps, slopes, narrow areas and low branches. The site needs a level, dry storage area where profiles and glass panes can be laid out in order and secured against tipping. Adequate working space is also needed around the T-shaped footprint for assembly.
