Your Garden Spaces Home Extension

You may not realise but we don't just build standalone garden studios, Garden Spaces build bespoke contemporary house extensions. They have become very popular as a stunning yet fast and economic alternative to a traditional block and brick solution.

Providing the Complete Solution

From the initial design to 'turning the key', we take all the stress away, leaving you to get on with your busy life. On your behalf, as well as design, installation, electrics, plumbing and decoration, we submit the Planning Application (if needed) and arrange the necessary inspections and certification required under UK Building Regulation.

Bespoke Design

Whether capitalising on poorly utilised space along the side of your property or creating more living space by extending into your garden, we will install your perfect solution. Together with our experienced designer you can create the size, shape, and look you envisage, maybe integrating a roof light, a roof over hang with decking below, or a covered a walkway as part of your bespoke design.

Benefits of a SIPs Extension

Our extensions are constructed using Structural Insulated Panels. SIPs are a modern composite building material, combining structural strength, insulation, vapour and air barrier, formed from two layers of OSB (oriented strand board) between which is a rigid core of expanded polyurethane foam. The panels slot together and are glued, nailed and screwed with long, high tensile self-tapping screws, ensuring great strength and 100% air tightness.

SIPs are fast becoming the contemporary building method of choice, not just in the UK but globally, for many reasons:

• Exceptional thermal efficiency ensuring low energy bills

• Robust strength and rigidity against extreme weather

• Fast clean construction meaning minimum build time

• Flexibility of design and external finish

• Ecological sound

Foundations

Each footing system is carefully considered, ensuring it is fit for purpose. Ground conditions, the proximity of trees and existing footings will influence the solution. In addition, we collaborate with our architect and of course Building Control who will inspect progress at several stages. We employ several systems, depending on requirement, including stainless steel screw piles, innovative eco-friendly pad systems or if necessary concrete rafts. Regardless of the type of foundation installed, the level of insulation surpasses required Building Standards, not least because the floor above is built using interlocking SIPs.

External Finishes

We offer a fabulous selection of external finishes enabling you to either blend your extension with your existing house or make it a stand out feature. The choice is yours:

  • Polymeric Render in a range of colours
  • Cladding: Western Red Cedar, Thermowood or grey larch
  • Brick slips
  • Contemporary slate
  • Stone cladding

Beautiful contemporary glazing solutions

Most people want to bring as much natural light into their homes as possible. A signature feature of our designs is undoubtedly the glazing. Using thermally efficient high-performance double glazing, we can incorporate one or many of the following features:

  • Bi-folding doors
  • Sliding doors
  • Sky lights and sun tubes
  • Tall, short, narrow and wide windows
  • Glazed corners
  • A choice of uPVC or powder coated aluminium frames
  • Integral blinds

Indoor Outdoor Space

Why stop with the inside? Your extension can flow seamlessly onto a bespoke decked area through bi-fold or sliding doors, instantly doubling your living space on sunny dry days.
