Popular Multi-Functional Designs:
- Open-Plan Living Areas: Combining spaces into a multi-functional kitchen, dining, and living areas to create a spacious and flexible environment.

An extension isn’t just about what’s inside – the roof can also be a defining feature. Statement roof designs are becoming increasingly popular for their ability to add architectural interest and elevate the overall design.
Popular Roof Styles in 2025:
- Green Roofs: Perfect for sustainability and blending with natural surroundings.
- Sloped Glass Roofs: Flood interiors with natural light and create a sleek, modern look.
- Cantilevered Roofs: Provide covered outdoor areas while making a bold design statement.
A statement roof can give your home a unique and sophisticated edge, in turn boosting both enjoyment and property value in the long run due to aesthetic appeal.

Key Wellness Extension Features:
- Home Spas: Imagine a private spa retreat with a sauna, steam room, or hot tub. Perfect for unwinding after a long day.
- Yoga or Meditation Rooms: These serene spaces can include natural light, calming colours, and even soundproofing for a peaceful atmosphere.
