9 Garden Buildings to Suit Any Garden Size

30 October 2025

Every household has a different amount of outside space to play with. From a flat with a balcony up to a farmhouse with acres of land, there are lots of eventualities to cater for and that’s something we think we do pretty well here at B&M Garden Buildings. Let’s take a closer look at some of the standouts for each garden size including sheds, greenhouses, log cabins and summerhouses.

Small Gardens

Balconies, patios and small gardens bring certain restrictions when it comes to the types of garden buildings you can introduce, but that doesn’t mean you have the compromise on quality or features. Small garden sheds and greenhouses still have a lot to offer.

(H3) 4' x 4' Palram Canopia Plant Inn Raised Bed Small Mini Greenhouse (1.18m x 1.18m)

Okay, so we know we’re probably stretching the definition of ‘building’ a little here, but this mini greenhouse from Palram Canopia is too good to miss. With its neat 4x4 footprint, it fits just as well on balconies and patios as in back gardens and offers 2 planters, 10 plant hangers and a water drainage system. You also get easy access via two adjustable lids, polycarbonate panels in an aluminium frame, a galvanised steel base and integral garden storage. And all at a great price!

4' x 3' Forest 4Life 25yr Guarantee Overlap Pressure Treated Windowless Apex Wooden Shed (1.34m x 1m)

Moving out into the garden and our most petite shed from the Forest 4Life range manages to pack a lot of features into its slender frame. Pressure-treated wood heads the list, because it brings with it a market-leading 25-year anti-rot guarantee that can’t be beaten and means you’ll never need to spend time on re-treatments. A fully modular design makes for a straightforward assembly process, the 12mm solid wooden floor is much stronger than most competitors (which is great for heavy gardening tools), and the ledged and braced security door helps to keep the contents safe.

6' x 4' Forest Timberdale 25yr Guarantee Tongue & Groove Pressure Treated Apex Shed (1.93m x 1.33m)

The premium Forest Timberdale shed line brings in some additional high-quality elements alongside its pressure-treated wood and huge 25-year anti-rot guarantee. These include a 12mm tongue and groove floor, 66mm x 33mm framing and a Z-frame door. You also get a superior roof, with a 140g reinforced polyester mineral felt cover, and an opening window with toughened safety glass. All of which adds up to a truly next-level small wooden shed for your garden.

Medium-Sized Gardens

It’s in medium-sized gardens where we start to see our log cabins, garden offices and summerhouses joining the party. These standalone structures need a bit more space to accommodate but give you a whole extra room to put to good use in return.

Palmako Ines 3.9m x 3m Log Cabin Garden Office (44mm)

Made from stunning Nordic spruce and with a chalet-cut design, this Palmako Ines log cabin (or garden office) will bring a splash of Scandinavian joy into your garden. It’s a light, airy and well-insulated building, with standout features including its full-length bi-fold doors and 44mm interlocking cladding. The doors give you the option of opening up one side of the building – perfect for bringing the outdoors in on warmer days – while the cladding emphasises that beautifully traditional log cabin look.

8' x 6' Forest Vale Modular Wooden Greenhouse (2.48m x 2m)

You can’t beat the elegance of the Forest Vale greenhouse, which combines a thick, traditional wooden frame with modern 4mm toughened safety glass and 12mm tongue and groove to create a real garden focal point. An 8’ x 6’ interior and two full-length shelves give you loads of planting and potting space. You also get professional installation included in the price with this one, so grab yourself a great deal today!

10' x 8' Yardmaster Green Metal Shed (3.03m x 2.37m)

Wooden garden sheds certainly have their charms, but Yardmaster knows a thing or two about producing attractive and multi-functional metal sheds like this 10’ x 8’ model. Built from hot-dipped galvanised steel and with seven protective layers against corrosion, this shed will withstand the harsh British weather with ease (and has a 15-year anti-rust guarantee to prove it). It’ll also keep your garden tools safe thanks to the lockable sliding doors (padlock not included) and anti-tamper bolts.

Large Gardens

A large outdoor space gives you the luxury of being able to pick and choose your garden buildings. From walk-in greenhouses to garages to workshops, it’ll all come down to the features that you’re looking for and the budget you have to work with.

6’ x 14’ Palram Canopia Harmony Large Green Polycarbonate Greenhouse (1.85m x 4.26m)

Speaking of walk-in greenhouses, this 6’ x 14’ building from the Palram Canopia Harmony line is a fantastic example. Loads of planting space is surrounded by a dark green aluminium frame and crystal-clear polycarbonate glazing. You get two manually opened roof vents and greenhouse guttering, as well as a lockable door that can be fitted with a left- or right-hand opening. Plus, a 5-year limited warranty for good measure!

Palmako Andrea 5.95m x 3m Contemporary Log Cabin Sliding Doors (44mm)

The Palmako Andrea Contemporary Log Cabin is one of the most stylish ways to give your house an additional room and your garden an eye-catching addition. This huge log cabin has more than enough interior space for a garden office, lounging space and hobby room combined, with two sets of sliding doors and one opening window providing views straight out into your garden. You can choose the positions of the doors and windows too, allowing you to tailor the building to perfectly meet your garden setup.

20' x 10' Forest Beckwood 25yr Guarantee Shiplap Pressure Treated Double Door Apex Wooden Shed (5.96m x 3.21m)

When it’s all about space, space and more space, then we’d recommend the imposing Forest Beckwood 20’ x 10’ shed. This superior garden building shares many of the classic Forest shed features, including pressure-treated wood and a 25-year anti-rot guarantee, along with the capacity to accommodate a workshop, exercise studio, music studio, gym or whatever else you require. When you want to add a generous room to your home without a costly extension, you can’t ask for much more.
