The Juliana Premium is an exceptional greenhouse that is extremely strong and has a very unique style.

Strength is an important factor with these Scandinavian greenhouses and the profiles have been improved over traditional design with "box" section bars which are far stronger. Each profile is grooved for an attractive finish and all doors, windows, base and fittings are powder coated black which gives the Juliana range their unique styling.

Standard features include large lockable stable doors which enables the top half of the door to open independently of the bottom, black base for support with low door threshold enabling easy access, bar capping for extra hold on the glazing, large roof vents, roof finials, concealed gutters with 40mm downpipes and is supplied in 3mm long pane toughened glass.​

Supplied in aluminium with black fittings or powder coated Anthracite Grey with black fittings.

Double doors are on the 9ft7" width.

Some of the Compact Standard Features


Extra eaves height

– creates more space for people and plants. The eaves height of 172 cm (incl. base of 12 cm) gives the greenhouse spacious dimensions.


Double stable door


– for optimal ventilation. The double stable door allows easy access to the greenhouse.


Low threshold

– makes it simpler to enter the greenhouse with a wheelbarrow or wheelchair. With traditional greenhouses, it is easy to stumble over high thresholds.


The roof ridge

– is fitted at both ends with beautifully shaped finials which act as seals for the profiles and at the same time also give the greenhouse a distinct look.


The triangular plate

– above the door lends the greenhouse additional stability and makes the JULIANA greenhouse recognizable even at a distance.


The door handle

– is rust-proof and fitted with an integral lock. A practical and great solution.


The downpipe

– with a 40mm diameter has a large intake capacity and is fitted as standard.


The gutter

– has a plastic seal at each end. The gutter can be easily cleaned – apply some light pressure to the cover and the flap can be opened.


The cresting

– available as an optional extra, simply slots into the ridge bar.


Black as standard

– the doors, windows and fittings are always black, regardless of whether you choose a powder-coated greenhouse or a mill finish greenhouse.


The plastic capping

– for fitting the safety glass and polycarbonate sheets – lend the greenhouse a complete overall appearance.


The design

– the characteristic grooves lend the profiles a unique appearance. Practical functions have also been incorporated into the profiles for easy assembly of the product.


The steel base

– like the doors and windows, is supplied in black as standard, and is designed so that it fits the low threshold.


The corner cover

– is fitted to the corner posts at the bottom of the greenhouse in order to conceal the black base joints. (bases are included in the UK).


The greenhouse profiles

– have been strengthened and improved without increasing the use of aluminium and without using unnecessary bracing which would spoil the appearance of the greenhouse.

    These are probably the most common accessory sold with greenhouses along with staging. Automatically opens the roof window according to temperature up to 18" to allow maximum ventilation, these are easily fitted with the supplied clamps and no drilling is required. Choose one for each window you wish to automatically open.

    Juliana Premium Greenhouse
    Sunday, 7 June 2015  |  Ralf

    . . . As I was looking for a particularly robust greenhouse due to high winds where I live, I first checked across the internet for reviews and advice before finally settling for the Juliana Premium. A good choice ! Strongly made, good quality components and a high standard finish on both the greenhouse and internal extras have made this a rewarding experience. Totally practical and utilitarian, the additional size has provided space for a mini conservatory of four chairs, a table and parasol. Automatic louvers and vent openers are invaluable as is the self-fertiliser feeding irrigation system. All in all, good old-fashioned service from South West Greenhouses with a quality product worth the money I paid for it.
    If constructing the greenhouse ones-self I do advise absolutely level foundations and patience with the construction process.
