**A flooring option is not included with this shed, it must be anchored down to a concrete or slab base using the optional anchor kit. This workshop requires three anchor kits. 


The 20 x 10 Absco Metal Utility Workshop in Zinc from Mercia is low-maintenance, excellent value, and offers a really impressive amount of interior space, making it perfect for home workshop use or even as a spacious storage shed. If it’s and abundance of space you are after from your garden building at excellent value, then this could certainly be the choice for you.  

The Utility Workshop has a traditional apex roof, which remains as popular as ever as a choice for our customers’ from a design perspective. However, this style of roof has more benefits than purely looks; it also adds a fantastic amount of headroom inside, maximising available storage space and giving you plenty of room to work in, if you should decide to use your building as a workshop. Its high ridge also ensures you have a really spacious interior, giving you excellent flexibility with what you can fit inside. As a metal shed, it boasts the huge advantage that it requires minimal maintenance during its lifetime. That means no yearly treatments, no painting and no running repairs. Simply wiping the building down occasionally and removing any debris from on or around it should be more than enough to keep it at its best.

Superior quality, high-tensile “Bluescope Steel” is used in the construction of Absco products, which is more durable, rigid and robust than the material used for many other metal garden buildings. A Zinc coloured “Colorbond” paint layer adds extra durability to the shed’s exterior and is a popular colour choice, especially in more modern settings, but will also blend harmoniously in a range of environments.

The Utility workshop boasts two wide-opening double doors to the front, which facilitate easy access even when taking the largest of items in and out. There is also a single door on the side elevation for more convenient access to the building’s contents. The shed can be locked by attaching your own padlock to the sliding padbolts that are supplied for the double doors and the single, side door respectively, so you can secure the building’s contents. The doors are braced for extra strength and security. And of course, because it features double doors, this makes taking ever larger items in and out of your shed as easy as possible.

Many metal garden buildings you will find on the market are notoriously fiddly to construct; however, every effort has been made with the Absco range to ensure that assembly is as straightforward as possible. Its SNAPTiTE assembly system makes every panel fit together tightly and with relative ease, while using far fewer screws than similar metal buildings in this price bracket. Pre-punched holes also speed up the installation process and make assembly easier. The edges are even rolled for extra safety when handling and constructing your product.

Many customers choose a metal garden building because they are fire retardant. In caravan parks, holiday parks and campsites, for example, fire regulations require storage that is non-combustible. If this is a case, a metal building could be ideal, though we do recommend that you double check with all relevant authorities before any purchase. A 30 year guarantee against rust and corrosion provides you with assurance that your purchase will last for years and years to come. The Utility Workshop is supplied flat packed with instructions and all the fixings that are required to complete assembly. You can also choose to have your building constructed quickly and correctly by our expert team of fitters if you would prefer.

Base Information

The 20 x 10 Mercia Absco Metal Utility Workshop in Zinc does not come with a floor and it must be anchored firmly to a suitable base. We recommend it is anchored to a pre-laid and level foundation of concrete, flagstone or timber. Please follow all instructions carefully. A shed anchor kit is available to purchase on this page. Make sure you include the correct number of anchor kits for your chosen size of building.

This shed requires three anchor kits to secure the shed in accordance with the manufacturer's instructions.

Booking Delivery

You will be required to book your delivery date at the time of placing your order (except for Metal Shed). Our 'Request a Delivery Date' service is available to the majority of areas and you'll find that the majority of the UK postcodes are FREE but some areas may incur a delivery surcharge and some postcodes are not covered at all. Select a 'requested delivery date' by entering your postcode in the 'Request a delivery date' section above. You will also be notified at this time if your area incurs a surcharge or delivery is not covered in your area.

Prior to Delivery

On the morning of your delivery date, you'll be sent an update by text with an estimated 2-hour delivery slot (this update can only be provided where a mobile number has been supplied on the billing address section at the time of checkout) together with a link to the manufacturer delivery portal where you'll be able to track your order.

Please note: Mercia Metal Sheds ONLY - your order is delivered by a courier you will not be notified prior to the delivery. If you are not in on the day of the delivery you will be carded and asked to contact the courier to arrange a new mutual delivery date. The estimated delivery lead time for Mercia's Metal sheds is identified on the product for the metal shed. Lead times are on working days (Monday - Friday) excludes Bank Holidays. These estimated lead times are provided by the manufacturer. Some remote areas will take a little longer.

Upon Delivery

Your order is delivered either kerbside or driveway and will be delivered on either a 3.5T, 7.5T or 18T Lorry. Unfortunately due to health and safety and insurance liabilities the driver will not be able to take your goods around to the back of your property but may upon request place the product at the side of the house if there are no access or restriction issues. We would not risk damaging your property whilst delivering a product to an unsafe location. Unfortunately, we will not be able to go through your property.

We would recommend against arranging for a third party to install the building before it's been delivered and checked that all parts are present, as we cannot be held liable for any third-party costs.


Orders with Assembly 

The lead time for our installation option is around 12 weeks from the date of order. With the installation option, the majority of orders will have their delivery and installation on separate days; there will be a small number of orders which will have delivery and installation on the same day. You will be advised by the manufacturer's installation team which category your order falls into.

Depending on the installation option for your order, you will be contacted within the delivery timescale and given a date for either delivery/assembly on the same date or a separate date for delivery and assembly.
