    Home extensions add space and value

    If you’ve outgrown your home and a conservatory isn’t the right fit for your home, we also offer made-to-measure home extensions. Whether you plan a new family room, kitchen extension, or just to enlarge your floor plan for more comfortable living, an extension could be the answer.

    A thoughtfully designed and carefully built extension expands your home to connect the current exterior and interior, feeling like it’s always been there. Not only will it really add space, but will also add significant value to your home—extensions typically offer a return on investment of around 12% of the property value when sold.

      High-performance roof options for your home extension

      Home extensions add interior space to your home seamlessly while providing either a harmonising or contrasting appearance from the outside. With a choice of tiled roofs, glass roofs or a combination, we can design the perfect solution to suit your home.

      [Text Wrapping Break]Tiled roofs are available in several colours and finishes. Not only are they incredibly robust they also offer excellent thermal performance. Glass roofs brighten your new extension, without compromising on its energy efficiency or security. Our high-performance glazing includes self-cleaning abilities and solar control that repels the sun’s rays when it reaches an optimum temperature inside. You can choose from a range of decorative finishes and beam features to give your roof a bit of extra personality.

      Types of Home Extensions

      Wraparound Extension: This extension connects to two sides of your house, usually the side and rear. It's good for opening up corners of your home to create large, open-plan living spaces that completely transform a property. This type of extension can significantly increase your living space and could raise your house value.

      • Rear Extension: This is an extension to the back of the house, which might create a larger kitchen or living area. It's perfect for connecting the interior of your house to the garden area, especially if you use large patio doors or a conservatory design. The key benefit is the additional living space without much disruption to the rest of your home.
      • Side Return Extension: This extension fills in the alleyway at the side of the house (common in Victorian terraces). It's great for turning a narrow kitchen into a large kitchen-diner. It maximises the width of your house without sacrificing too much garden space.
      • Over-Garage Extension: Creating a new room or suite of rooms above an existing garage. It can add considerable living space without altering the footprint of the house. It's an effective way to create space, especially if you don't regularly use the garage for parking vehicles, and can provide a great area for a home office or guest suite.

      What is the alternative to a conservatory?

      If you're looking for an alternative to a conservatory, there are several options to consider, depending on your needs and budget:

      1. Orangery: An orangery is a more substantial structure than a conservatory and is designed to be a more permanent extension to your home. An orangery typically features brick or stone pillars, a solid roof with a glazed lantern, and large windows.
      2. Extension: An extension is a great option if you need more living space in your home. It can be designed to blend in with the rest of your house and can be tailored to your specific needs.
      3. Sunroom: A sunroom is a type of extension that is typically made entirely of glass, offering great views of your garden while providing shelter from the weather.
      4. Loggia: A loggia is an outdoor space that is enclosed on one or more sides by arches or columns. It provides shade and shelter while still allowing you to enjoy the outdoors.
      5. Garden room: A garden room is a detached structure that can be used for a variety of purposes, such as a home office, gym, or guest accommodation. Garden rooms can be designed to blend in with your garden and can be fully insulated for year-round use.
