Receiving a Good Set of Feedback

Reading through Lifetime’s top-drawer feedback, the features spotlighted above accede to high degree. Purchasers adore the attractive visual stance Lifetime’s present, the stalwart construction that provides stability against climate changes & burdensome storage pressures, not forgetting the quality finishing touches and spacious storage accommodation accompanied by generous headroom height.

Facilities this size do take 2 people at least a day to construct, a daunting project for many novice DIYers I do agree.

The only thing I can add here relates to the most important part of a resin shed construction, a stipulation we were completely unaware of until the delivery of our chosen shed. It’s imperative they’re mounted on a solid level surface. Decking is okay but you have to bear in mind how much weight a unit this size will accommodate in relation to subsidence. Levelled concrete, asphalt, tarmac or paving on the other hand assures enhanced solidity.

We had to postpone our assembly for a week in order to prepare the correct foundations because every sales website failed to mention this ruling prior to purchase. We found out by the instructions headlining this stipulation.

Upon assembly however, it became obvious why this ruling’s essential. Panels line up with ease due to commencing from levelled ground thereby ending up with a perpendicular construction, a skewiff stance will only lead to further complications. We accomplished an enjoyable straightforward assembly. For those who choose to skip this step take note because once you’re 8 ft up, aligning the roof panels will present problems if you’re not level on the footings.

Explore Lifetime’s Composition Advantages


Chunky Robust Construction

Don’t confuse this model with the single walled structures on the market, this is a different kettle of fish altogether. This range is manufactured with dual walled resin fascia sheets, the chunkiness of the roof and facade’s composition adds firmness to the overall stability of the shed.

The walls incorporate steel reinforcements, secured together with high grade metal screws ascertains a firm fix meanwhile the roof wraps around a supported metal framework, virtue of steel trusses under-girding the structure. This particular model comprises 5 A-Frame steel beams stretching across the roof width inside.

The doors consist of a double skinned resin conformation reinforced internally with a meshing of steel providing more robustness to the entrance whilst intensifying security.

The floor’s makeup regards a strapping resin base constituting added toughness thereby strengthening the composition to subsist hefty stresses associated with gardening services.

All things considered, Lifetime have created a shed boasting a stalwart construction.

Lifetime's 11 x 13.5 ft Sturdy Construction

Composition Assures Weather Resistance

Lifetime’s recyclable composition is manufactured through a process termed High Density Polyethylene (HDPE) where the polyethylene molds to combine an inner & outer skin, internally ribbed provides a stocky firm & stable surround. Embedded within the wall sheets lies a steel structure where the next sheet connects, securing together with high grade steel screws.

The molding process creates the semblance of horizontal wood panelling radiating desert-sand that two-tones effortlessly with the doors brown tint exhibiting architectural style meanwhile on account of the panels ribbed inner construction, the composition’s built to withstand dents.

Polyethylene along with UV toughening compound delivers all-round weather-resistant advantages. Unaffected by rain, snow and sun, it doesn’t decay, rust or rot meanwhile refrains from splitting and bleaching when subject to the scorch of direct sun, resulting in a shed unsusceptible to deterioration through adverse weather conditions.

To conclude the virtually maintenance-free advantages this shed offers, a quick spray down regards the minimalist operation for upkeep in order to retain the immaculate appearance. Alternatively, a soft brush and scrub with detergent or an occasional pressure-wash represents additional easy-clean solutions.

The Benefits of a Robust Imperishable Resin Roof

The advantages of a resin roof is that it’s unsusceptible to decay, impermeable to rainwater thereby safeguards storage meanwhile upholding the strong point and envy of conventional wooden sheds topped off with roofing felt and their quick disintegration process, Lifetime’s never succumb to re-roofing.

Lifetime roofs are manufactured into a twinned lining of High Density Polyethylene, alike the fascia panels albeit molded to create a stylish slate effect topping. Encased around a metal frame they secure into place, buttressed by a series of 5 A-Frame steel trusses stretching across the internal rafters enhancing support for weighty lumps of snowfall.

An apex structure is my favourite roof design, where a high pitch effectuates immediate drainage of rainwater and impedes the ability of water puddling meanwhile seepage-in at the roof-wall junction is averted on account of the roof’s overlap with the walls.

The additional advantage a steep roof provides, reciprocates increased headroom height inside. There’s over 7 feet from the A-Frame beams to the floor plus the additional headroom above the rafters, a copious amount enabling an adult to stroll around without stooping over.

Embedded within the roof lies 2 impact resistant skylights, illumining daylight to brighten the interior.

Lifetime Polyethylene Resin Roofs

Muscular Integrated Resin Floor

Initially unsettled by the metal sheds absence of built-in floors swayed our attention towards resin constructions that do incorporate, in order to escape another episode of a wooden floor rotting away.

The reason we’re hugely impressed regards the fact there’s no admittance for the outside environment to blow debris inside at the base of the walls, unlike our garage floor that receives a wave of leaves in autumn due to the small gap under the door. Neither is there chance of rain puddling the shed floor, we were determined to find an escape route to eliminate future problems.

Lifetime floors incorporate a mix of polyethylene along with additional ingredients that toughen the makeup, provide an anti-slip surface whilst equipping the floor with resistance to oils and solvent stains delivering an easy to clean surface. Molded into hefty resin sheets, they interlock with adjacent floor panels whilst simultaneously interlocking with the walls.

The toughening elements result in a floor capable to subsist demanding stresses associated with heavy gardening machinery suchlike ride on mowers endure however it’s important the floor sits on a solid level surface thereby under-girded to withstand the forces.

Lifetime advise to anchor the floor down onto the foundations to increase the sheds stability. The kind of anchor bolts are conditional to the foundation material.

Lifetime's Tough Wearing Built-In Floor

Inside Lifetime’s 13 ft Expanse 

The windows operate through a swing design allowing the opening for additional fresh air along with entering daylight meanwhile up above embedded in the roof, two impact resistant skylights illumine the interior with natural light during daytime hours.

Situated front and rear, incorporated air vents distribute fresh air circulation inside, replacing sweaty atmospheres during humidity. A feature we find keeps storage in pristine condition, couple this with the built-in floor, a clean atmosphere is presented.

Air Vents create a fresh ambience

Included with this shed regards a shelving system comprising 7 shelves and 2 peg strips along with metal hooks for hanging gardening tools. We and many others install free standing shelves to accommodate heavy storage. When you evaluate the 11 ft width these sheds are blessed with, there’s oceans of room to facilitate stand-alone shelving.

Due to the extensive amount of storage room represented here, 11 by 13 feet can house oceans of gardening equipment including lengthy tools and parasols, patio furniture & accessories, BBQ paraphernalia, park the family’s bikes, a super haven for kids toys & sporting equipment etc meanwhile driving in or rolling in a lawnmower represents no issues due to the generous dimensions, copious headroom and hard wearing surface.

Inside the Lifetime 11 x 13.5 ft Shed

Broad Strapping Double Door Access

Wide beefy twin doors open up the entrance providing widespread access for driving in machinery meanwhile as seen in the photo above, the doors swing wide open for unrestricted access.

The doors polyethylene manufacture molds into a chunky dual walled composition resembling a door constructed from brown wooden panelling, creating a stylish yet robust entryway.

The left hand door contains 2 internal deadbolts that side into grooves above and below the door for locking up further to providing a stay-closed position in wild weather. The doors swing open via their full length galvanised steel hinge pins rather than separate small hinges.

Easy grip handles comprising press buttons situated on their top operate the metal latch system meanwhile reinforcing the doors structure regards steel meshing and a steel infrastructure to which the padlock clasp secures to, strengthening security.

To lock the door, a padlock is required to slot through both clasps once the doors are closed.

Weather-Resistant Assures Low Maintenance

Lifetime presents a make-up resistant to weather depreciation, the impermeable composition is not susceptible to rotting nor rusting, paramount for storage protection.

All the exposed steelworks are powder coated to prevent corrosion meanwhile the resin floor resists decay. The entire surface is easy to clean, a spray down with a hose or pressure washer does the trick, restoring the shine in minimalist time.

Dependant on landscape surroundings, ingrained dirt may start to appear however a great tip regards adding white vinegar to warm soapy water and removing with a soft bristled brush.

Lifetime cater to chuck away those old varnish and paint tins because there’s no yearly maintenance issues nor future re-roofing services associated with a polyethylene composition. I generally hose ours down after watering the plants on a summers evening.

Stepped-Out Assembly Approach

The most important measure to undertake prior to installation is to ascertain a levelled substrate of solidity determines the foundations. Most assemblers choose a concrete or paving-stone type base to refrain from future subsidence wood decking may suffer, this 13 footer will accommodate a hefty amount of gear.

Obeying by this rule, we found all the panels aligned plumb for a quick & efficient assembly, the perpendicular construction derived from levelled ground overcomes leaning stresses and determines the doors correct operation plus the floor is capable of surviving burdensome tensions.

Another important role to undertake regards attaining firm anchoring, only a solid substrate suchlike asphalt or concrete will accomplish a firm fix to ascertain stability. We had to purchase our own anchor screws, their type is dependant on the base material therefore not included.

Top tips we picked up are to thoroughly read through the instructions beforehand to become familiar with the process. Plenty of off-site jobs like installing the door hardware can be undertaken before assembly. We also laid out all the parts in order to the instruction steps and accomplished generating an organised build.

Lifetime estimate this shed takes on average 8 hours to build with 2 people using household tools to construct. We just started at the beginning and slowly worked through the steps one at a time implementing what’s shown albeit our shed was no where near these dimensions however the same principles apply irrespective of size.

By watching the video below, you’ll grasp the procedure straight away.

    Great, Great, Great, these sheds are only great look wise but are very durable and strong. I will forward it to some of my friends who are planning to renovate their garden and I might need a shed i future, will do it as per your article and advises you have mentioned, thank you.

    • Hey Sarah, Lifetime’s composition is durable and strengthened by their dual walled skin design whereupon a ribbed inner-layer substantially buttresses the external side which constitutes the wooden-effect styling.

      If you and your friends call for spacious outside storage accommodation, this style caters. Unusually for a resin manufacture these facilities spread 11 feet across their width, competing resin sheds usually restrict their breadth’s to 8 feet however due to their minimum 11 feet depths, a fair size garden plot is required for constructing.
      I have measured our garden but unfortunately they’re too big and would over-obtrusively dominate our outside space therefore you need a fair stretch to enable construction.

      You mention their strength, which is derived from a metal framework into which the panels adjoin in conjunction to steel trusses reinforcing the roof producing a top able to accommodate hefty snow-loads during winter.

      Hope your friends find suitable storehouses to accommodate all their outdoor gear. Shed Sizes steps up competing weather-resistant sheds in order of size meanwhile Weatherproof Steel Storehouses may interest those who require substantial secure engineering.
      Thank you,

    i have been researching storage options other than the traditional wood framed units. the maitenance is almost too much having to paint wash and replace wood year after year . i came across your review of these lifetime storage solutions and i am absolutely glad i did they seem high quality and the name lifetime makes me feel safe in the fact they are built to last! i am thanks to your strong detailed review in the process of ordering one now thanks so much for taking the time to provide me a place to buy as well !!

    • Hey Garry, thanks for commenting on Lifetime’s heavy plastic sheds manufacture.

      Your situation with regards to finding an alternative to the toilsome challenge of re-coating traditional sheds with paint along with felted roof replacements sounds very similar to our predicament a few years back.

      Lifetime’s chunky fascia walls of polyethylene deliver the alternative solution on account of their immunity from decay deterioration. Their imperishable composition is as sturdy as it is stylish meanwhile maintaining their unblemished appearance is swiftly restored with a wash. We click the shower connector into the hosepipe and occasionally spray our shed down during summer, simple as that!

      Lifetime promote their polyethylene design and composition as the best resin sheds on the market, I would never judge here as there’s plenty of competing sheds offering alike manufactures in terms of robustness that delivers durability however their 8 ft wide sheds are one of the largest sellers on the market, especially in America.

      Good luck choosing your size Garry, these 11 ft wide sheds start with a depth expanding 11 feet and multiply in 2.5 ft lengths all the way up to 26 feet deep, there’s a walkway.
      All the best,

  3. Looking for a sturdy plastic shed but width I have is only 5 feet but could go to 12 feet width do you make bespoke sheds

    Many thanks

    • Hi,
      Thanks for asking about whether there’s a 5 ft width heavy duty plastic shed available.

      We don’t sell nor manufacture plastic sheds, our service relates to delivering in-depth reviews regarding the quality resin variety and point visitors towards the best suppliers at the most competitive prices, hence we have no allegiance to any particular manufacturer.

      5 ft width is very tight, I’ve been searching around for your size but can only come up with one solution. Keter Factor’s 4 ft width x 6 ft depth is the only shed that I’ve come across that fits your width. Is there any possible way you could place two of the Keter 4 ft x 6 ft sheds back-to-back accomplishing two separate sheds with doors at either end, this would equate to 12 ft total length. Failing that, would one 4 ft x 6 ft shed suffice?

      Sorry I can’t be any more helpful but maybe this is a solution.

      Check Factor 4 x 6 ft prices here:

      Hope this helps, thanks for your enquiry,

  4. Sherry and John

    There is a lot of buzz on the Internet about Spring and getting your garden and yard tools, implements all organized. It appears that your sheds will do exactly that. This is a great presentation. Wow steel supported that is amazing. My husband wants to build the shed that we want. However, We are now seriously considering your product. I am truly impressed by this product and your presentation. Just one question,do anchors come with the sheds for heavy winds? Good Job.

    • Simon

      Hi Sherry and John,

      Thanks for calling in and reading about these heavy Lifetime Plastic Sheds.

      Yeah, These are very sturdy sheds due to their steel reinforcement. You ask about additional anchoring:

      All plastic sheds should be anchored down into the foundations and this is by virtue of purchasing the correct anchor bolts dependant on your base material, whether it’s concrete or wooden foundations. Embedded within the floor are anchor positions where you place the bolts/screws.

      If you are exposed and worried about stormy weather, Lifetime do additional anchor kits for their sheds. These sheds require the 11 ft width anchor kit.

      If you click on the second set of prices for the UK and scroll down the page, there’s two sets of prices for each shed. One is for the shed, the other includes installation. With regards to this company who offers assembly, they ask you to message them if you would like to include the anchor kit and they will add this to your order.

      If you are in the USA, click the first link and many of these companies offer installation too. I would message them and ask whether they can add the anchor kit to your order. The ones who offer installation are shed companies and they will know exactly what you mean.

      I hope this helps and good luck with your decision, have a great year in the garden,


  5. How To Build A Business Online

    Amazing and thorough review of this particular shed Simon. The passion you have for this product clearly comes through in your critique in a very positive and knowledgeable way.
    I am no handyman but with help I can see how this would be a great addition to the backyard.
    The quality of materials is so advanced these days making the shed look like a little house. I can see these lasting a lifetime on a concrete foundation. Is this the one you have installed at home?
    Thanks for this again:)

    • Simon


      Thanks for calling in and reading about these heavy duty garden sheds.

      You mention you’re no handyman, a lot of people say the same however I am noticing on the sales sites just lately that there’s quite a few companies offering installation which is a great idea especially for a shed this size as it can be a daunting process if you’re not a DIYer.

      Yeah, these new materials are becoming so stylish these days and the beauty of plastic is that it’s weather-resistant, durable and easy to clean. These Lifetime sheds are dual skinned reinforced with a steel infrastructure which is a huge advantage to accomplish a real sturdy structure that provides stability.

      We chose a smaller width Keter shed due to size restrictions however I wish we could fit this size shed into the garden but unfortunately we have a protected tree with low branches right in the middle of the garden, 11 ft width is too wide for our plot but what a fabulous size this would make for our storage.

      What I like about this material is when we water the plants on a summers evening I quickly spray the shed down and bring back assembly days pristine finish, all in a few minutes.Suits me down to the ground.

      Thanks again and good luck choosing,


  6. Arta

    • Simon

      These Lifetimes are really beginning to take off due to their heavy duty, weather-resistant and durable construction. They have such a stylish attractive design, yet are so easy to clean whilst feedback comes through mightily impressive. They are great sturdy sheds.
