Conservatories

The right conservatory style transforms both your home’s appearance and how you use the space. Traditional designs offer timeless charm, while modern lean-to options work well where space or height is limited. Solid roof technology can be incorporated into any style to improve comfort and efficiency. We guide you through planning rules and design choices, ensuring your conservatory is practical, compliant, and built for year-round use – adding genuine value to your home.

Sun rooms

A sun room is a stylish and affordable way to transform your outdoor space into a bright, versatile living area. Designed as a modern alternative to a traditional conservatory, this uninsulated glass sunroom allows you to enjoy your garden in comfort throughout the year, whatever the weather.

Rear Extensions

Having a rear extension is a fantastic way to enhance the space, functionality, and value of your house. An extension can provide you with the extra room you need for a growing family or to create your dream kitchen, dining room, or living space. Furthermore, the benefits of an extension do not stop at additional space. It can also increase the value of your property and make it more attractive to potential buyers.

Wrap Around Extensions

Want to maximise both the rear and side of your home? A wraparound extension blends the two, giving you a bright, spacious layout that really works for modern living. With many years of practical experience and a strong commitment to continuous learning and development, we have the knowledge and expertise to successfully manage even the most complex wraparound extension projects.

Kitchen Extensions

A kitchen extension can transform how a home is used every day. It can create a larger kitchen, dining space, family area, utility room, pantry, better storage and a stronger connection to the garden. A successful kitchen extension needs the kitchen design and construction planning to work together. Cabinetry, appliances, islands, rooflights, doors, utilities, drainage and electrical routes should be planned before the build is too far advanced.

Single storey Build

Building a single storey extension is a cost effective alternative to moving house. These extensions will allow homeowners in Leeds, Harrogate and West Yorkshire to design additional living space with a layout that suits the needs of them and their family. Single storey extensions are commonly installed as a rear extension or side extension. They are especially popular when combined with open plan living and rooms that connect the home and garden. Single storey extensions don’t just allow more natural light into the home, they create a brighter and healthier space. Our extensions are built to last, offering high performance without compromising on style and function.

Multi Storey Build

A multi-storey extension  is the perfect solution for families who need an extra living space over the head. When a property is extended vertically by adding an extra floor it’s a multi-storey extension. It is developed to meet the changing needs of a growing family. A storey or a double-storey house extension is also its part. However, a multi-storey allows you to build additional space no matter the number of floors as long as they are feasible.
