We operate our architectural design services throughout London, Hertfordshire and the United Kingdom. Our fixed fee for loft conversions and house extensions pricing structure contains key elements that you would need to build your project. The key elements are: planing application, building regulations and structural engineering

We do not ask clients to sign up to our full construction services after the initial consultation, this means there is no commitment beyond our design phase. This is advantageous to our customers as they are free to tender their designs to other contractors and compare quotes in order to make the best decision to suit them. All our design clients will automatically receive a fixed price tender from Nuhous for construction phase of your project so that they can compare our competitve prices against other contractors. We will of course be happy to complete the build stage for you too. We operate in this way because we know it is not possible to give a fully accurate quote for building work until the designs are complete and we believe in being honest and transparent about the costs involved.

Costs can vary as no two projects are the same. Each is designed to meet the specific needs of the customer.

Kitchen, side, rear extensions and loft conversions are a great way of adding new space to your property, as well as  increasing its value, especially in london. If you need more space it is cheaper to extend than move home.
