Garden Annexe Ideas to Inspire You

Stuck for garden annexe ideas? Let iHus inspire you with some of the different styles, designs and finishes available, and discover how you can customise your annexe to suit your needs, lifestyle and personal taste.

From contemporary flat roofs to traditional pitched roofs and beautiful natural oak cladding, there are plenty of ways to make your garden annexe your own. Below, we explore some designs from our Classic Annexe Range, alongside some bespoke projects we’ve created for our customers.

Garden Annexe Ideas

When you first begin your journey towards building a garden annexe, it can be difficult to visualise what your finished home might look like.

At iHus, we work closely with you to create an annexe that reflects your individual requirements, from the layout and exterior design to the fixtures and fittings inside. Whether you prefer something traditional, contemporary or completely bespoke, here are some garden annexe ideas to get you started.

Pitched Roof

If you love the appearance of a traditional home, why not choose a granny annexe with a pitched roof? Pitched roofs can give your annexe a charming, homely character and, depending on the design, offer opportunities for vaulted ceilings and an enhanced sense of space.

The stunning example below is our Cantley Extra model, finished in dark grey Marley Cedral weatherboard with a terracotta tiled pitched roof and feature canopy. The contrast between the dark cladding and warm roof tiles creates an attractive, traditional appearance.

Our Cantley range is available with flat or pitched roof options, allowing you to select a design that complements your existing property and garden.

Natural Green Oak

For a more natural, rustic appearance, untreated green oak cladding is a beautiful choice. As the timber weathers over time, it develops a distinctive character that helps your annexe blend into its garden surroundings.

The bespoke garden annexe pictured below features green oak weatherboarding, a pitched roof, black trim and uPVC fascias, alongside two VELUX Integra roof windows. Bi-fold and French doors help connect the interior living space with the garden, creating a light, welcoming environment.

Untreated green oak cladding is also available as an upgrade within our Classic Range, making it a fantastic option for anyone seeking a more traditional or countryside-inspired design.

Cool and Contemporary

If modern and stylish is what you’re after, a flat-roofed garden annexe could be the perfect choice.

Take this contemporary annexe we built for a customer in Maidstone, Kent. Featuring a dual-aspect oversail canopy, the exterior is finished in dark grey Marley Cedral weatherboard, complemented by anthracite grey and white uPVC windows and doors.

A grey decked patio and walkway complete the design, creating a seamless connection between the annexe and the surrounding garden.

Flat roofs with oversail canopies are a popular option for achieving a clean, modern appearance. You can also incorporate features such as exterior LED lighting, composite decking and a choice of window and door finishes to personalise the design.

Two Bedrooms

Our granny annexes are available with either one or two bedrooms, giving you the flexibility to choose a layout that suits your lifestyle.

A two bedroom annexe can be a great option for couples who want a little more space, relatives who require an additional bedroom, or families looking for flexible accommodation within the garden.

The additional room could also be used as a home office, hobby room or occasional guest bedroom, depending on your needs and the property’s permitted use.

Our Melton annexe is one example of a spacious two bedroom design, providing comfortable, self-contained accommodation with separate bedrooms and open-plan living space.

Truly Bespoke

Every garden and household is different, and sometimes a standard annexe design won’t quite meet your requirements. That’s where our bespoke design options come in.

Whether you’re looking to create an accessible home, adapt a layout to suit an unusual garden shape, or select exterior finishes that complement a traditional property, our Classic Range offers extensive opportunities for customisation.

Some projects also require additional consideration because of their location, particularly properties within conservation areas or other areas with specific planning constraints.

For example, the bespoke annexe pictured below features a reproduction Cotswold stone pitched roof, creating an attractive traditional appearance that complements its surroundings.

While planning requirements vary by property and location, our experienced team can help you explore suitable designs and manage the planning application process.

Cosy and Compact

If garden space is limited, a compact granny annexe can provide everything you need for comfortable, independent living without overwhelming the surrounding outdoor space.

The Cantley is one of our smaller one bedroom models and has been thoughtfully designed to make the most of the available space.

Measuring 8.55m long and 4.55m wide, the standard Cantley features a practical layout incorporating a bedroom, bathroom, kitchen and living area.

With prices starting from £105,268, the Cantley offers an attractive option for individuals or couples looking to downsize while remaining close to family.

For anyone who would prefer a little more room, the Cantley Extra and Extra Plus provide additional space while retaining the same carefully considered approach to design.

Make Your Garden Annexe Your Own

One of the most exciting parts of designing a garden annexe is choosing the features that make it feel like home.

With our Classic Range, you can personalise everything from external cladding and roof styles to kitchen finishes, flooring, bathroom fittings and accessibility features.

Whether you prefer a traditional pitched roof with natural oak cladding or a modern flat-roof design with contemporary grey finishes, we’ll help you explore the options available.

You can also choose practical additions such as accessible wet rooms, ramp access, wider doorways, external decking and solar panel packages, depending on your individual requirements and chosen specification.
