Top 6 House Extension Trends for 2025 

Are you considering increasing your living area? It can dramatically increase the functionality and value of your home, and for optimal use, house extensions are often more advisable than relocation. Be it a kitchen, bedroom, or a home office, moving may not always be the best solution.  

We are Total Build, and we have worked with clients in West London who want house extensions. Over the years, we have learned what most homeowners look for when adding aesthetically pleasing value to their homes. In 2025, homeowners will experience a paradigm shift where new lifestyle expectations, sustainability strides, and design preferences will be the new norm. Here are the top extension trends that will take precedence in the upcoming year.  

1. Open-Plan Living Spaces 

As previously discussed, these structures have gained great popularity over the years, but their relevance will significantly increase in 2025. With an increase in remote working jobs and indoor activities, people expect their homes to have bright spaces that can accommodate multiple functions.  

Key Features:  

• Less separation in walls gives the illusion of a larger space.  

• Smooth transition between the cooking, dining, and leisure spaces.  

• Increased natural light due to enlarged bi-fold or sliding glass doors.  

Open plan house extensions will be ideal if you wish to create an area in your house that can seamlessly shift from work to leisure or if you want to host gatherings. 

2. Sustainable and Low-Energy Additions 

In 2025, homeowners will strive towards eco-consciousness, making sustainability a key focus. Many individuals are now opting for eco-friendly materials and energy-efficient solutions to further reduce energy expenses and their carbon footprint.  

Common Eco-Friendly Enhancements: 

• - Use of solar panels for harvesting renewable energy 

• - Usage of advanced triple-glazed windows for greater insulation 

• - Incorporation of reclaimed wood and recycled bricks as sustainable construction materials 

• - Use of shrubs on roofs to improve insulation and air quality 

These elements are beneficial to the environment, but even more important, they improve the overall value of the estate in the future.  

3. Integration of State-of-the-Art Technology within Homes 

Additions to homes are incorporating technology rather than the other way around. Thanks to advanced technology, homeowners can now control lighting, heating, and security more easily.  

Common Smart Enhancements: 

• - Lights and heating can be controlled using voices 

• - Smart security systems with access remotely 

• - Blinds that can be adjusted to control natural light automatically 

• - USB ports embedded into walls for charging devices 

Convenience and security are greatly enhanced with smart home extensions, making daily activities effective and easier.  

4. Home Garden 

Home gardens are being innovated to become additional spaces for the home. Many homeowners are now incorporating garden rooms that can serve as living spaces, personal gyms, or even offices. 

Why Garden Rooms Are Trending: 

• They provide a self-contained and quiet area conducive to hobbies and work. 

• They create additional living space without the need for extensive renovations. 

• They are easy to set up and cause little disruption. 

• They improve the value of the house. 

If you have a garden, this is a great way to maximise your outdoor space while adding functionality to your home.  

5. Glass Extensions for Maximum Light 

As much as any trend for extending a home, glass extensions are predicted to become extremely popular in 2025 as they put a twist on the design of a modern and classy extension. These designs boast superb views and ample sunlight, wrapped in a stunning design. 

• Floor-to-ceiling glass panels showcase the outside beauty. 

• Added brightness comes from sleek glass roofs. 

• Sleek, frameless designs give an ultra-modern aesthetic. 

• Energy-efficient glass helps to retain heat.  

If you want a contemporary way to extend your home, a glass addition to your house can do it with light and style.  

6. Loft and Garage Conversions 

Rather than extending outwards, many West London residents are making use of spaces that already exist, such as garages and lofts. Turning these spaces into livable areas is an effective way of increasing a house's market value. 

Trendy Conversions for Lofts or Garages: 

• Loft rooms featuring private bathrooms 

• Cinema or media rooms 

• The garage converted into an office space 

• Lofts or garages rented out for extra income 

You may consider the conversion of garages and lofts to increase space without the need for an extension. This will work perfectly if you have an empty garage or loft.
