Good delivery, so far good shed


Reuben  starstarstarstarstar

Excellent! Good quality for the price. Delivery was swift (quickest I could find anywhere!) and the shed arrived exactly when I was told it would. Amazing that an 8x6 shed can be delivered on a standard pallet! Very easy to assemble. Took me less than a day on my own. Thanks -)

Very pleased with the shed, thou I thought the instructions could have been a little clearer.


Ray  starstarstarstarstar

Went for the modular 8x6. Very well designed. Gives you plenty of options where the door is positioned and which side its hung from. Relatively easy to assemble. Didn't like the colour of treatment used but easily disguised with a dark oak oil based treatment. 12mm tongue and groove looked more like 10mm. Delivery is what it says. Delivered on the kerbside no help if you want it anywhere else. Be careful when you unpack it. If its on a slight slope it will crash to the ground with potential damage. Definitely needs two people. Very surprising how everything is packed so tightly. Overall very pleased. Thank you.

Quality, easy to put together.


Ken Brooks  starstarstarstarstar

Very pleased with both the construction and design of my shed. the ease with which it went together was impressive, no hassles and everything fitted. The wood treatment is only basic but serves to protect the timber if it gets wet. Final preservative is up to the individual. I had laid and levelled the floor the day before the Big Build having first treated the underside of the floor with three coats of bitumen. Actual build time for two of us over the two days was only four hours to turning the key in the lock, I have still got to felt the roof but otherwise not bad at all.

For the price of the shed what I got was very good. So simple to erect I put it up on my own within a day but I’ve had experience of doing that before but never the least it was very easy. I had done a lot of searching before I found tiger sheds and hardly any came up to the quality to price ratio. Many thanks

Great little shed, went for the 8x4 option, very easy to put together and fitted exactly where I wanted it to go. It arrived as advertised within the 3 days.

Crafted by us, configured by you. The next in the Tiger Flex series is the Flex Pent™ Windowless, providing the versatility of Flex Apex™ with a more contemporary pent roof. The shed’s windowless update is ideal for those who prefer to keep their building’s contents out of sight. The modular door panel of the flexible shed can be fitted on any side, in any position, and the door can be hung either right or left hinged. The shed features superior grade, 12mm finish shiplap cladding with extra thick 44x28mm framing for robust durability.

The Flex Pent™ Windowless features extra high eaves for a taller interior, allowing most people to stand comfortably without having to stoop. Covered floor joists lift the building off the ground without letting anything in or under the floor. Heavy duty green mineral roofing felt is supplied as standard for excellent protection against the elements, and fascias, bargeboards and corner strips provide an attractive finish.


No fakes, copies or substitutes can get close to the quality and craftsmanship of the real thing - The individual design and configuration options of The Flex Pent™ are protected by UK registered design right and an international patent pending to ensure that this truly unique range of buildings is an absolute one of a kind.

Unlike many budget competitor products this shiplap shed is built with only the highest quality materials and many garden sheds in the market simply cannot compare!

  • THIS FLEX PENT WINDOWLESS SHED is clad with high quality, 12mm finish shiplap tongue and groove cladding – beware of shiplap sheds that feature poorly finished rough edged boards milled out of inferior timber often with a thinner finish.
  • THIS FLEX PENT™ WINDOWLESS SHED features heavyweight ‘rounded 4 corner’ 28x44mm finish framework throughout for strength and durability – beware of shiplap sheds that use rough sawn ‘matchstick thin’ framework that barely hold the shed together.
  • THIS FLEX PENT WINDOWLESS SHED features superior grade tongue and grooved boards in the floor and roof sections and contains NO cheap sheet materials such as OSB or chipboard – beware of shiplap sheds that use single piece OSB / chipboard roofs that offer inferior protection in the areas where you need it most.
  • THIS FLEX PENT WINDOWLESS SHED retains our extra high ridge height – beware of shiplap sheds that are incredibly low, preventing comfortable standing inside.

It is essential that this Flex Pent™ shed is assembled strictly in accordance with the instructions supplied on a firm and level base constructed from a suitably durable material. It should also be treated shortly after assembly and then annually thereafter with an appropriate high quality preservative and all glazing units must be sealed, inside and out, with silicone or other water tight sealant.

For more information on how to correctly assemble and maintain your Flex Pent™ shed please consult our comprehensive help centre.

If DIY is not your strong point then fear not because our professional home installation service will do it all for you! The pro-install team will contact you soon after the delivery of your garden building to arrange a suitable time and date for the fitting.

A Firm and Level base must be in place and accessible before installation can take place - failure to provide this may incur additional costs. Pro-Installation does not include the fitting of any extra items such as locks or handles, and windows will be tacked into place only. Please view our Installation Page for full Terms and Conditions, which can be found here.

As standard cabin installation does not cover the installation of roof shingles. If you purchase a cabin with shingles and would like the shingles to be installed in addition to the building itself you must also add on the 'shingle installation' option at additional cost.
