A granny annexe is more than functional accommodation. It's a home that should bring joy to its occupant and enhance your property. The design possibilities are broader than many people realise. Whether you prefer contemporary minimalism, traditional cottage charm, or something uniquely your own, there's an annexe style to match. Let's explore the options and features that transform a standard annexe into something special.
Contemporary and Modern
Clean lines, large windows, and minimalist aesthetics define the contemporary annexe:
- Flat or mono-pitched roofs create a sleek silhouette
- Floor-to-ceiling glazing maximises natural light
- Anthracite grey or dark cladding provides sophisticated contrast
- Aluminium-framed doors and windows in dark finishes
- Open-plan interiors with integrated kitchen-living spaces
- Works brilliantly with modern houses and urban gardens
Traditional Cottage Style
For properties with character, a cottage-style annexe feels naturally at home:
- Pitched roof with clay tiles or slate
- Cream or white painted timber cladding
- Traditional-style windows with multiple panes
- Feature porch with period detailing
- Climbing plants encouraged on trellis sections
- Ideal for rural properties and period homes
Green Oak Elegance
Green oak cladding creates a stunning natural appearance that weathers beautifully:
- Fresh-cut oak starts honey-coloured and silvers gracefully over time
- Each annexe develops unique character as the wood ages
- Natural material complements gardens of all styles
- Can be combined with large glazed areas for dramatic effect
- Particularly suited to rural and semi-rural locations
- Premium option that creates a genuine talking point
Brick-Effect Cladding
For annexes that need to blend with brick-built houses:
- Modern brick slips create authentic appearance
- Available in red, buff, grey, and multi colours
- Match or complement your existing house brickwork
- Combines brick lower sections with cladding above for visual interest

- Planning officers often prefer brick in established residential areas
Scandinavian-Inspired
Light, bright, and connected to nature, Scandinavian style works beautifully for annexes:

- White-painted interiors maximising sense of space
- Warm wood floors and simple, functional furniture
- Integrated outdoor seating areas
- Perfect for smaller annexes where space efficiency matters
The L-Shaped Layout
An L-shaped annexe creates sheltered outdoor space and interesting interiors:
- Protected courtyard or patio area between the 'wings'
- Natural separation between bedroom and living areas
- South-facing aspect captures maximum sun
- Creates visual interest from multiple angles
- Works particularly well on corner plots

The Accessible Annexe
Designing for mobility needs needn't compromise on style:

Vaulted Ceiling Drama
A pitched roof with exposed interior creates remarkable sense of space:

Kitchen Design Options
The kitchen is central to independent living. Consider these approaches:

- Compact kitchen: combined appliances for smaller footprints
- Open-plan: kitchen visible from living area, social cooking
- Separated: screen or peninsula creating distinct zones
- Finish options from budget-friendly to high-end
- Most residents spend significant time here, invest accordingly
Bathroom Styles
Bathrooms can range from purely practical to luxurious retreat:
- Walk-in shower: accessible, practical, contemporary
- Shower over bath: flexibility for those who enjoy baths
- Wetroom: fully waterproofed, spacious feel, excellent accessibility
- En-suite versus separate: depends on layout and preference
- Underfloor heating adds comfort and aids drying
- Good bathroom design significantly improves quality of life

- Planting to soften and screen
- First impressions matter for the occupant's pride in their home

Frequently Asked Questions
Can I choose any design for my annexe?
Within planning constraints, you have significant design freedom. In conservation areas or near listed buildings, traditional styles are usually required. Elsewhere, contemporary, traditional, or hybrid designs are all possible. We'll advise what works for your property.
Which design features add most to the cost?
Natural materials (green oak, stone) cost more than composite alternatives. Bi-fold doors cost more than standard doors. Vaulted ceilings add complexity. Air source heat pumps cost more upfront but save on running costs. We'll help you prioritise within your budget.
Can I change the design after building starts?
Minor adjustments are usually possible during the design phase before manufacturing begins. Once construction starts, changes become difficult and expensive. That's why we spend time getting the design right before proceeding.
How do I know what will suit my garden?
During our free site survey, we discuss design options in the context of your specific property. We consider sightlines, existing buildings, garden character, and your preferences. We can provide visualisations showing how different styles would look.
What's the most popular annexe design?
Contemporary styles with grey cladding and large windows are currently popular. However, 'right' depends on your property. A traditional cottage suits period homes; contemporary suits modern houses. The best design is one that feels natural in its setting.
