Home extensions are one of the most rewarding ways to transform a property. Whether you’re dreaming of a bigger kitchen, an extra bedroom, or simply more space to relax, extending your home can completely change how you live day to day.

Rear House Extension Ideas
Rear extensions are one of the most popular ways to add space, especially for homes with generous gardens. Extending from the back of your property can completely change the way you use your home, blending indoor comfort with outdoor living.
Kitchen Extension
The kitchen is often the heart of the home — a place to cook, socialise, and spend time with family. A kitchen extension can dramatically improve your day-to-day life by creating a bright, spacious, and functional area tailored to your lifestyle.
Imagine adding bi-fold doors that open directly onto the garden or a skylight that floods the space with natural light. With our design and build service, we can help you create a kitchen that’s both practical and stylish, whether you prefer a modern open-plan layout or a traditional farmhouse feel.
A well-designed kitchen extension also adds significant value to your property. According to Homebuilding & Renovating, a kitchen extension can increase your home’s value by 10–15%, making it a smart long-term investment.
Garden Room Extension
For homeowners who love the idea of connecting more closely with nature, a garden room extension is a fantastic option. Often designed with large glass panels or sliding doors, these extensions blur the line between indoors and outdoors, creating a light-filled living area that’s perfect all year round.
A garden room can be used as a relaxing lounge, a dining space, or even a creative studio. The emphasis is on natural light, sustainability, and a sense of openness. 1Horizon’s builders in Northampton specialise in designing extensions that complement your property’s architecture while maximising your garden views.
For inspiration on how to enhance your garden alongside your new extension, the Royal Horticultural Society offers excellent guidance on layout and planting ideas.
Front of House Extension Ideas
A front extension can transform the first impression of your home. It’s a subtle yet powerful way to improve both practicality and kerb appeal.
Porch or Boot Room
Adding a porch or boot room is a small change that makes a big difference. It gives you a designated space to remove muddy shoes, hang coats, and store outdoor gear — ideal for busy families and pet owners.
Not only does this help keep the rest of your house clean and organised, but it also adds an inviting entrance that enhances your home’s character. With clever design details, such as built-in benches and hidden storage, your porch can be both functional and beautiful.
Home Office Space
Working from home has become a permanent part of modern life, and many homeowners are now seeking a dedicated workspace that feels separate from the main living areas. A front-facing office extension provides a quiet, professional environment for productivity — without taking over existing rooms.
At 1Horizon, we’ve helped clients across Northamptonshire create bespoke home offices designed for comfort, light, and focus. Whether you need built-in shelving, acoustic insulation, or bespoke windows to bring in natural light, we’ll help design a space that truly works for you.
If you’re setting up a workspace, the Health and Safety Executive’s guide to working from home provides useful advice on creating a comfortable and ergonomic environment.
Small House Extension Ideas
You don’t always need a large extension to make a big impact. With thoughtful design and planning, even compact additions can completely change how you use your home.
Utility Room
A utility room is one of the most practical extensions you can add — perfect for laundry, storage, or even a dog-washing station! By creating a separate utility space, you free up valuable kitchen area and keep noise, clutter, and mess out of your main living zone.
Our design experts can help you make the most of small spaces by integrating clever storage solutions and durable materials that withstand daily use.
Downstairs Toilet
Adding a downstairs toilet is another small but valuable improvement. It’s convenient for guests and family members alike and especially useful for homes with multiple floors.
This type of mini-extension often requires minimal planning but provides long-term benefits in terms of comfort and accessibility. With careful positioning of plumbing and drainage, we ensure your new WC fits seamlessly into your existing layout.

Double-storey House Extension Ideas
If you’re looking to maximise space and add major value, a double-storey extension is the ultimate upgrade. It allows you to increase both your ground-floor living space and your upstairs accommodation simultaneously.
Wraparound Extension
A wraparound extension combines a side and rear extension, creating a flowing, open-plan layout downstairs while adding more room upstairs. This is ideal for growing families who require additional bedrooms, a home office, or a larger kitchen and dining area.
With over 15 years of experience, our builders in Northampton manage every stage of these complex projects — from design and planning permission to the finishing touches — ensuring your new space feels completely integrated with the rest of your home.
Over-Structure Extension
An over-structure extension (built above an existing garage or single-storey structure) is another brilliant way to expand without increasing your footprint. It’s ideal for adding a new bedroom, ensuite, or dressing room upstairs.
Working closely with Amico Design, our team ensures the new floor blends seamlessly with your existing structure — both visually and structurally — while meeting all relevant building regulations.

Loft Extension Ideas
When extending outward isn’t possible, looking upward can be the perfect solution. A loft conversion unlocks unused attic space, creating an entirely new floor without requiring additional ground space.
Across Northamptonshire, many properties have pitched roofs that are ideal for conversion. Whether you’re dreaming of a peaceful master suite, a creative studio, or a guest room, our design and build experts can make it happen.
Benefits of a loft conversion:
- Adds living space without extending your footprint
- Boosts property value — up to 20%
- Improves energy efficiency with modern insulation
- Offers design flexibility for bedrooms, offices, or playrooms
For advice on energy efficiency, see the Energy Saving Trust’s guide to roof and loft insulation.
