Here at Windsor Installations, we hold years of experience helping our customers create their perfect home extension in Gloucestershire.

Why An Extension

When it’s done properly, a new home extension can be so much more than an additional room. A home extension can transform your home to make it work for your lifestyle, giving you and your family that extra bit of space to enjoy.

Whether you’re planning on using your extension as a new playroom, a second living area or a dining room with a view, our team of home extension specialists in Gloucestershire are ready to help. And when it comes to selling your house later on, a home extension will also increase the price of your property.

Our team of home extension specialists will work with you to create the perfect bespoke extension for your home, maximising the available space but blending it seamlessly with your existing property. We always aim to create a space that is truly yours. As such, we ensure that every aspect of the building project is supervised by you, so you always feel in control.

Before we even start talking about plans, one of our team will come out to assess the site and consider issues like access for lorries and materials, the structural impact on your existing home and whether you will need planning consent or if the work falls under Permitted Development (PD). We believe that preparation is key to a successful project and it ensures that you understand exactly what will be happening at all times.

Why Choose Us

Once the site inspection of your property is carried out, our team will meet with you to talk through your vision for your home extension.  Our extension experts will help you create a new space that works both structurally and for your family life.  All designs will comply with Building Regulations, covering a range of factors from fire to drainage.

Once the plans are approved and our team is on site, we want you to continue to have peace of mind.  This is why we make two guarantees to our customers.  The first is that any work carried out on your home will be done so to the highest standards, within all relevant Health and Safety legislation. The second is that we will only use industry standard equipment which is safe and reliable to carry out our work.

Whilst building work can get messy, we always endeavour to ensure that we minimise the disruption to you and your family.  We can’t guarantee some mess but we promise to leave your home just as you would want it.

Design & Installation

Alongside any structural changes to your home, we can also help deliver the complete vision for the interior of your property including your new extension.  We offer a high quality, bespoke interior decorating service, tailored to suit the needs of you and your home.  We only use top of the range products to ensure a high class finished product.

Here at Windsor Installations, we want to help you create the home you have always dreamed of and it’s a lot closer than you think.  Our team of experts will ensure the build runs smoothly from start to finish and that your vision and plans are detailed throughout.  For us, it’s about making your vision become a reality.

  • Mark and his team have recently completed my kitchen refurbishment. This was the second time I have used Windsor Installations, the first was a bathroom refurb. I have nothing but praise for all aspects of their work including their interaction with you as a customer. Mark will give an honest quote and his team will often complete little extras to correct any issues they find as they go or to improve the design. In the case of my bathroom, which is a small area. Mark changed the design to save me money on a smaller washbasin and the refitted the original basin in a better position. I would strongly recommend Windsor Installations to anyone looking to improve their home.
