Home Extension Trends for 2025 in the UK

Brought to you by Sketchpad – It all starts with a sketch

With UK homeowners continuing to reimagine how their spaces can support work, family, relaxation and sustainability, 2025 is shaping up to be a bold and creative year in home extensions.

At Sketchpad, we’ve been sketching, designing and bringing bespoke extensions to life across the UK — and here’s what we see as the top trends defining the year ahead.

1. Open‑Plan, Multi‑Purpose Living

Homeowners are prioritising flexibility. Gone are the days of boxed-in rooms and underused corners. Open-plan layouts that combine kitchen, dining, and living spaces remain king but with a twist: clever zoning, movable partitions, and dual-use furniture that adapt to daily needs. Ideal for family time, entertaining, and even remote working.

2. Bringing the Outdoors In

Large-format sliding or bi-fold glass doors continue to be a staple in 2025 extensions, connecting interiors seamlessly with gardens or patios. Indoor-outdoor living is not just for summer months it’s about natural light, airflow, and extending your usable space all year round.

3. Sustainable, Energy‑Smart Designs

Eco-conscious choices are becoming non-negotiable for UK homeowners. From triple-glazed windows to low-carbon materials, underfloor heating, solar panels and green roofs sustainable features are being integrated from the sketch stage. This isn't just a trend it’s smart investment for the future.

4. Smart Home Integration

Home extensions are becoming smarter. With automated lighting, heating, blinds and voice-controlled appliances, modern homes in 2025 are designed to be efficient, secure, and ultra-convenient. Tech is now part of the architecture discreet and intelligent.

5. Natural Materials & Biophilic Touches

Wood, stone, and clay-based finishes are making a strong comeback. Homeowners want warm, tactile materials that connect them with nature. We’re seeing more green walls, skylights, and indoor planters built into extension designs all creating a peaceful, wellness-driven environment.

6. Minimalist Design with Personality

Minimalism isn’t about cold, clinical spaces anymore it’s about clarity, purpose and beauty. Think clean lines, smart storage, hidden pantries and bespoke cabinetry balanced with unique textures, lighting features, and statement materials that reflect your taste.

7. Smaller Footprint, Smarter Layouts

Not everyone is building big and that’s perfectly in line with 2025 thinking. Even modest extensions can transform how a home functions, with careful spatial planning and clever storage. It’s not about square metres it’s about meaningful metres.

8. Bold Colours and Creative Finishes

Neutral tones still have their place, but 2025 invites more personality. Expect to see pops of colour, deep green kitchen units, terrazzo flooring, and mixed-material finishes that celebrate individuality. Your extension should feel like you not a copy-and-paste showroom.
