Home Extensions
in Kingston

A home extension in Kingston is the most effective way to add valuable living space without the cost and disruption of moving house. Whether you're planning a rear extension, side-return extension, or wraparound extension, Grand Innovations delivers extensions that transform how you live.

Our Kingston extension projects are designed to maximise natural light and create seamless connections between indoor and outdoor spaces. We specialise in open-plan kitchen-diners with bi-fold doors, spacious family rooms with roof lanterns, and functional utility and boot rooms that add genuine practicality to your daily life.

Grand Innovations has extensive experience working with Royal Borough of Kingston upon Thames and understands the specific planning policies that apply across Kingston. Many single-storey rear extensions fall under Permitted Development, meaning you may not need full planning permission. We confirm this for your property and handle all applications, structural engineering, and building regulations on your behalf.

Our unique weekly billing model gives Kingston homeowners complete financial transparency. There are no large deposits — you pay only for work that has been completed and signed off each week. This approach has earned us the trust of families across London who value honesty, quality, and control.
