This buying guide provides some top tips on finding the perfect garden structure for you and your outdoor space.

Whether it's a shed for storage, a log cabin to create extra space without all the building work or a playhouse to excite the imagination of children, large and small; we have the building for you!

In the modern world, people increasingly view their garden as an extension of their home, whether to relax in, entertain in, or simply enjoy the view, the right garden building can add that special touch.

Here you will find all the information you need to make that purchase, from measurements to garden building aftercare.

Size & position

Size is an important consideration when choosing a structure for your garden. What do you plan to use it for, where it will be positioned, how much of your garden you are willing to loose?

Things to think about

  • Be mindful not to place your structure under large trees as you may have problems with dropping branches or large roots
  • If you require electricity think about getting power to it to allow you to use power tools or lighting
  • It's best to have some shade if possible as your garden building will tend to get very hot inside during the height of summer
  • Keep in mind the position of the sun. A greenhouse or summerhouse potentially can be located directly in its path; however you'll need a workshop or shed to be cooler if you're planning on working in them, so choose a more sheltered position for this
  • If you'll be working with plants consider the water-supply
  • It's a good idea to locate your building next to a path as it can get very muddy and damp in the winter
  • Try to position the building a minimum of 12" away from walls and fences to allow it to be installed correctly and to allow you to get things in and out
Building the base

It's is essential to provide a firm, level and square base; without which, your building will become unstable and will deteriorate rapidly. These are dependant on capability so do asses your requirements then maybe engage the help of a builder.

Please note if you are constructing the base for a building over 12' x 8', a garage, a sectional building, a corner unit, a gazebo, or a building with no floor, a purpose-built concrete base is recommended.

Concrete base

A concrete base is the strongest and most durable form of foundation, typically four inches thick (100 mm). It has many advantages such as no need to build a separate shed floor, its easily cleaned & there is no danger of the floor rotting. This really is a job for a competent DIYer, or a professional builder as it requires excavating, formwork, mixing concrete and placing and finishing this.

    Paving slabs

    The most common form of base; simple & effective. See our how to guide on laying slabs or visit our YouTube channel to watch a comprehensive short film.

  • Treated timber bearers

    These are a cost effective simple solution base for you outdoor building & can provide a more pliable fitting to enable you to move the location of your structure.

    Fitting your bearers is relatively simple; clear any vegetation then use pegs and string to mark out an area for your base. Excavate the marked out ground to around 2" (50mm) deep. After removing the pegs and string lay approximately 1.5" (40mm) gravel or soil. Level with a rake and a spirit level.

    Lay your bearers across the gravel/soil in equally spaced intervals of approx 400-600mm ensuring that they're level with one another by using a spirit level.

Maintenance

To maintain the quality and appearance of your building its best to treat with a durable wood stain [where applicable] and then at regular six month periods for the lifetime of your structure. We sell a wide range in a variety of colours.

Shape

Choosing the right shape of greenhouse will help to make the most of your space as well as provide the right growing environment.

  • Lean-to greenhouses

    Ideal for small spaces, such as patios and balconies. Locate against a sunny wall for a space saving option that offers enough height to grow popular crops such as tomatoes and cucumbers.

  • Traditional or 'apex' roofed greenhouses

    Offer plenty of standing room in the centre for working in your greenhouses. Many models include integral gutters to collect rainwater from the slanted roof sides – why not install a water butt outside your greenhouse to have a helpful supply of water for your plants?

  • Curved eave greenhouses

    Provide a little more space around the edges. These are a great choice if you plan to spend lots of time working in your greenhouse, or intend to grow larger or taller crops.


How many doors?

The majority of greenhouses come with either a single or double door at the entrance. Single door options are great where space is limited, or where you wish to maximise growing space in the greenhouse. Double doors are a more accessible option, and are worth considering if you wish to be able to take a wheelbarrow or garden trolley inside. Don't forget, opening the doors to your greenhouse are one of the best ways to ventilate greenhouse your on a hot day to stop plants from overheating and dehydrating. Double doors will give you more options to control in the internal temperature of your greenhouse.

Glazing

There are wide ranges of greenhouse glazing options available. Glass is a more traditional choice, and B&Q offers both horticultural glass as well as stronger toughened glass greenhouses. Polycarbonate has different properties to glass, and tends to be more cost effective.


Advantages of glass glazing

  • Greater weight ratio than polycarbonate, providing a stronger structure
  • Allows more light into the greenhouse
  • Replacement glass panes are readily available
  • Traditional greenhouse look

Advantages of Polycarbonate glazing

  • Retains heat during winter, and helps to keep the greenhouse cool in summer
  • Diffuses sunlight to minimise risk of scorching
  • Virtually unbreakable
  • Glazing panels are lighter weight, so easier to transport

    All our greenhouses are a great starting point for growing your own fruit, vegetables and ornamental plants, but with a few accessories you can be well on your way to producing healthier, stronger and more productive crops.

  • Greenhouse staging and shelving

    Make the most of space within your greenhouse using wooden or metal staging to provide a work surface. Ideal for potting and keeping delicate plants off the ground in colder weather.

  • Auto-vents

    Keeping your greenhouse at the right temperature is important – although you want your plants to be warm, hot weather can dehydrate and scorch leaves, causing damage. An auto-vent opens greenhouse windows automatically when the temperature rises, and closes them again when it cools.

  • Greenhouses heaters

    Lengthen the growing season of your plants, or keep delicate species safe over the winter with a greenhouse heater. Use to raise the temperature inside during the cooler months to maintain a temperate growing climate.

Installation

Installing a greenhouse can be hard work, but a satisfying task that will give you years of use. We offer a range of home delivered greenhouses available with installation, as well as offer an installation service for some. So if you'd rather someone else do the hard work, we can help.

If you'd rather DIY, B&Q can provide all the tools for the job - plus we also stock Snap & Grow greenhouses designed for quick installation.

Tools & materials

Determine your use and storage needs before choosing your shed. Careful planning is a must, then pottering in your shed will be a true pleasure.

When choosing your shed there are a number of things to consider; the style and type of material. In general there are two types of shed, Apex and Pent. Apex sheds come to a point in the middle & Pent roof sheds have a roof that slopes from high on one side to low on the other.

At B&Q we sell sheds in a range of materials, each with their own benefits. Choose from traditional timber, robust metal or low maintenance resin, ranging from small patio storage to the largest workshop.

Don't forget to check out our information on size, position and maintenance before you buy.
