Architectural Design Practice in Nottingham and Derby


Welcome to A1 Architecture

An innovative Architectural Practice based in Nottingham. We have a passion for creating contemporary architecture with sustainable design, specialising in house extensions, loft conversions and new build homes.

Residential Architecture

Whether you’re looking to extend your home with a loft conversion, or a house extension A1 Architecture can help. We take your initial ideas and put together design concepts that will work for you. We will guide you through the design process from Planning permission approval to Building regulations. We strive to create beautiful houses to allow you to feel truly at home.



You may love current home but just feel like you need the extra space but don’t want the hassle of moving. A house extension may be the right option for you, it will create you the extra space that your family needs.

At A1 Architecture, we provide creative architectural design solutions to make your new house extension fit in and around your way of living. Adding house extension with a large kitchen / family room can add anything from 10% to 15% value to your home.

Adding a loft conversion to your home is becoming more increasingly popular, especially with new permitted development rights allowing a rear dormer loft conversion to be built without requiring a planning permission.

A Loft Conversion can be a great way to turn that unused loft space, into a warm welcoming extra bedroom with an en-suite and can add anything from 10% to 20% value to your home.



In addition to our fixed price packages we also offer bespoke full architectural services for New Build Homes and Self Builds. We cover the RIBA 0-7 plan of work from project assessment to project delivery.

We provide tailored services to meet your project specification and requirements, depending on the level of involvement you would like from us in your project.

Here at A1 Architecture our aim is to provide an affordable solution to architecture. When thinking about having a loft conversion or house extension built and the thought of architects and building design your first thought may be that an architect is really expensive, that does not have to be the case. We provide affordable fixed price fee’s house extensions and loft conversions throughout Nottingham, Derby & Doncaster.

A ‘’Grand Design’’ style Architect is not always required for house extensions and loft conversion. Generally clients will just require architectural plans to obtain planning permission approval and building regulations drawings for the construction and building control.
