Grow More with A Plastic 6x4 Greenhouse

Perfect for The Garden or Allotment

Benefit from longer growing seasons and grow fresh greens, vegetables and fruits in a plastic 6x4 greenhouse.

Greenhouses allow you to continue gardening and growing despite the weather conditions outside, they give you the ability to grow a wider range of plants and veggies including exotic plants.

Whether you are new to gardening or quite the experienced gardener, a plastic polycarbonate greenhouse is the perfect choice to helping you achieve your growing goals.

Our strong maintenance-free galvanised steel frame ensures your greenhouse is a solid and sturdy construction whilst the translucent 4mm polycarbonate twin wall roofing will provide great insulation and protect your crops from the frosts and harsher weathers.

Twin wall polycarbonate is 100% UV protected, longer lasting and diffuses light better preventing it from scorching your plants.

Unlike glass, polycarbonate plastic can withstand impacts from footballs, hailstone and even rocks making it an ideal material if you have children or grandchildren that love playing outside.

The greenhouses double sliding doors allow easy access and the rear sliding window offers a quick way to ventilate the greenhouse on those hot summer days.

There are screw holes in the framework which allow the greenhouse to be attached and anchored to a base of your choice.

  • Ultimate Greenhouse 1.2m (4x6ft)

    Posted by Bob Wills on 25th Jul 2018

    Replacement for one which I previously purchased years ago, excellent product, very strong and ideal size for a small garden, relatively straightforward to erect, would highly recommend Norfolk greenhouses for price and first class service, ordered on a Monday delivered following Thursday. Will use some of old greenhouse frame for shelving / staging in new one and will also have enough to make a cold frame for additional plant protection. Very pleased.

  • must be willing to spend time assembling

    Posted by Charlotte on 23rd May 2016

    Arrived within 2 days super fast delivery, started assembling the greenhouse however found some parts rather challenging. I still don't know how to fit the two rectangular cladded pieces and screws for the roof hart to sceew in, as well as this the i would have liked all cladding to be cut to size as after cutting mine it wasn't correct and doesn't match the smart look that the rest has, however I am pleased with the product and would recommend.

  • Patience required ... but good value

    Posted by Steve on 21st May 2016

    Excellent turnaround from point of order to delivery; though courier didn't arrive during allocated time.
    All parts checked out as listed. Would certainly recommend laying out and grouping together.
    Found some of the assembly instructions challenging, specifically the bit around the door and window; the orientation of the panel housing strips and the cutting of these. Accessing the roof apex to fit roof panel screws was awkward, indeed haven't managed to put the middle screws in.
    That said, the final result is good and my toms etc. are well at home in their new environment. Would recommend for the price. Good job!

  • so great we ordered another one!!

    Can't praise this Greenhouse enough, it is an excellent size and keeps the young plants and seedlings I have in it in perfect condition. No problems putting it up everything was there and it also looks very expensive. We had previous Norfolk greenhouses for over 25 years so are still impressed with the company.
    Can't recommend highly enough

  • Worth the Effort of Assembly - Good Quality

    Posted by Dave A on 15th Apr 2016

    Arrived quickly.
    Small hiccup with the tracking of the shipment, but quickly resolved. Frame assembly is a bit fiddly as it is all set screws and nuts.

    If you have problems keeping the screws located whilst assembling, use some masking tape to hold them in place. Once tightened, you can remove.
    I added 'P' seal strips which helped seal the joints between the polycarb sheets and the frame. Available from Scr... you will need 2 packs @ £10 to complete.
    I also used some thin strips of gaffer tape to hold the top triangular panels in place whilst fixing the roof in place, this also helps to seal it.

  • Top Quality at an Unbeatable Price

    Posted by Keith Deakin on 29th Feb 2016

    Received within a few days.Unpacked to count the pieces and, unfortunately, found that the pointed ends of 2 of the panels were damaged, probably in transit.I need not have worried because when I e-mailed Customer Services about this, replacements arrived the next day!!What excellent service.The assembly instructions are explicit and well illustrated.Now assembled and looks a treat Can't wait to put it to good use,

  • Solid, safe and good value

    Posted by Nick Burns on 9th Dec 2015

    I've had a Norfolk greenhouse for several years, on a windy exposed plot, and it's been as solid as a rock, polycarbonate sheets very safe compared with glass, even when the lawnmower crashed into it.
    Moved house recently and just bought a new 6+4 greenhouse on black Friday, bargain of the year, even at full price these greenhouses are excellent value for money

    Bought as a birthday present for an 80 year old - excellent
    once erected - will have to buy myself one now so as not to be outdone!!

  • Fantastic Value.

    Posted by Mrs Gillian Warrender on 3rd May 2015

    I have been a customer for nearly 30 years and have 2 of the 1.2 ultimate greenhouses, one of which is about 15 years + old and is till in perfect order and still producing great seedlings and plants, it has survived through gales, rain, thunder lightening, snow and a jack russel called Molly. I would not hesitate to use Norfolk for any gardening products. I highly recommend them for garden equipment that is value for money and stands the test of time.
