Investing in a garden room is a significant purchase, but with careful planning, you can create a stunning and functional space without overspending. Drawing on 25 years of experience in the garden room industry, we’ve compiled practical tips to help you maximise your budget while ensuring a quality result.

Prioritise Specification Over Size

Many buyers are tempted by the larger footprint of log cabin-style buildings, especially when they come with a lower price tag. However, these often lack essential features like insulation in the floor, walls, and roof, double glazing, and a specialist breather membrane to guard against moisture ingress.

Instead of opting for a larger but less insulated structure, choose a slightly smaller, well-specified garden room. This ensures a comfortable, durable, and energy-efficient space that will stand the test of time.

Consider Pre-Designed Garden Rooms

Customisation can quickly increase the cost of a garden room. Pre-designed models offer an excellent alternative, combining high specifications with affordability and shorter lead times.

While these designs may limit your choices regarding size and door/window configurations, they often strike the perfect balance between quality and budget.

Choose Exterior Cladding Strategically

Exterior cladding significantly impacts the overall cost of your garden room. Many companies now offer the option to combine premium and cost-effective finishes. For example, you could use Western Red Cedar on the most visible walls and a more affordable material, such as cement particle boards, on less prominent surfaces.

Other durable and low-maintenance options include Siberian Larch, Thermowood, and British Cedar, each offering a stylish yet cost-effective finish.

Save on Interior Finishes

A fully plastered and decorated interior is appealing but can substantially increase labour costs. To save money, consider alternatives like:

  • White melamine wallboards: Light, easy to clean, and cost-effective.
  • Plywood or MDF finishes: These can be left bare for an industrial look or painted to match your style. Though this requires additional work, it can lead to significant savings.

Affordable Door and Window Options

Doors and windows greatly influence both the cost and aesthetic of your garden room. Here are some cost-conscious tips:

  • Opt for French doors: These are generally the most affordable and can create a wide opening into your garden.
  • Mix French or sliding doors with fixed glazing: Achieve the modern, open look of a glass wall without the high price of bi-fold doors.
  • Consider uPVC frames: While aluminium frames are sleek and modern, uPVC options are equally durable and available in trendy grey tones, often at a lower cost.

Be Realistic About Pricing

A high-quality, fully insulated garden room designed for year-round use typically starts at £8,000. While cheaper alternatives exist, such as imported models with minimal insulation and lower-grade materials, these often incur higher maintenance and running costs in the long run. Moreover, they don’t add the same value to your property as a quality garden room.

Explore Self-Build Options

For those with DIY expertise, self-building a garden room can offer substantial savings. Many companies provide self-build kits, allowing you to assemble a pre-designed structure yourself. Alternatively, sourcing materials and designing your own building from scratch can yield even greater savings.

If you’re considering this route, companies like Warwick Buildings and Garden2Office offer shell-only options, enabling you to finish the interior to your specifications.
