Project management

The Building Company maintain a single point of contact throughout the lifetime of your project.

Giving you piece of mind when comissioning the work on your home and allowing us to maintain our high standard of work for clients. Using our full design and build service means that from our initial meeting our architects can design and plan your new extension or loft conversion, we can then take care of all planning or permitted development details.

Once these details have been finalised our team of fully trained and insured tradesmen can complete your project.


A loft conversion is a fantastic cost effective way to enhance the value of your home with out having to move out.  A loft conversion is also a great way to convert unused space in your home into a great useable new space such as an en-suite bedroom, nursery, studio or office.  The type of loft conversions that can be done depends on the type of home you live in.


Weather its for a new kitchen, a home office, home gym or a kids playroom, building a new home extension is a fantastic cost effective way to increase the value and add more space around the home.  We have a vast experience of carrying out extension works to a variety of classic and modern buildings.  From your initial survey we will assess your property and use ideas to design a bespoke extension package optimising space and appearance of your home.
