When it comes to extending your home, ST Grayson offers both single and double extensions. 

A single extension is a great option if you require a little extra space, such as a larger kitchen or an additional bedroom, whereas a double extension can provide a substantial increase in living area, allowing you to create a spacious open-plan living space or add multiple rooms to your home. 

ST Grayson will work closely with you to understand your needs and design an extension that seamlessly integrates with your existing property.

Our commitment to quality, attention to detail, and customer satisfaction, means you can trust us to deliver exceptional results.

Garage & Loft Conversions

Garage conversions are an excellent solution for homeowners who have an underutilised or unused garage. Instead of letting that valuable space go to waste, ST Grayson can convert your garage into a functional living area. 

Whether you want to create a home office, a playroom for the kids, or even an additional bedroom, their team of experts will transform your garage into the space you desire.

If you're looking to maximize the available space in your home, a loft conversion is a perfect choice. ST Grayson specialises in loft conversions, turning your unused loft into a stunning living area. 

Whether you envision a spacious master bedroom, a home gym, or a dedicated workspace, their team will work closely with you to design and construct a loft conversion that meets your needs and complements your home's style.

In addition to our extension and conversion services, we also provide guidance and advice when it comes to drawings and planning permission. We understand that navigating the planning process can be daunting, so we are there to assist you every step of the way. 

Our team will work with you to create detailed drawings and help you obtain the necessary planning permissions, ensuring a smooth and hassle-free process.

We also understand that home extensions and conversions can be complex projects, involving multiple trades and coordination. We can therefore project manage and oversee every aspect of the construction process, ensuring that your project is completed on time, within budget, and to the highest standards.

Whether you require a single extension, double extension, garage conversion, or loft conversion, ST Grayson is your go-to partner for home extension and conversion building services in Hertfordshire.
