House Extension

An extension is perfect for anyone who is looking to expand any part of their home, including single or double storey extensions, kitchen extensions, side extensions and conversions.
Whether you wish to create additional space, or simply want to install a state-of-the-art new kitchen to bring your home into the 21st century, our masterful design team will work closely with you to achieve your desired home extension.

Loft Conversions

Something as simple as a loft conversion can have a huge impact in unlocking the hidden value of your home. Loft conversions create an entire new living space from something that was once neglected. We can convert your unused loft space into a liveable area, such as a bedroom, office, living room or play area. Loft conversions are a great way to add extra space and value to a property and, most importantly, they can be a very affordable investment.

New Build Projects

For property developers or those who wish to start a build from scratch, The Market Design & Build offers a bespoke, new build service.

Our highly skilled team can work on all aspects of a build, including complex tasks like the demolition of existing structures, right up to adding the finishing touches to your new property.
