Find out why hiring an architect is vital for your house extension or even more specifically, what to expect with planning and design with house extensions in Birmingham.
Whether your project falls under Permitted Development or requires a full Householder Planning Application, navigating Birmingham’s local guidelines is essential to avoid enforcement action. While planning permission focuses on the appearance and impact of your extension on the Birmingham streetscape, Building Regulations are a separate, mandatory requirement ensuring the structural safety, insulation, and fire protection of your build.
As specialist architects in the Birmingham area, we manage these distinct processes. from initial Planning Application submissions to detailed Building Regulations drawings, ensuring your design meets national safety standards while respecting local character.
We move beyond simply adding square footage to create intuitive, fluid layouts that better reflect how you live. By eliminating restrictive barriers and mastering internal ‘zoning,’ we transform cramped rooms into expansive, light-filled environments where cooking, dining, and relaxing coexist perfectly.
A well executed extension is a high yield investment that often outperforms the local Birmingham property market. By balancing architectural aesthetics with functional square footage, we ensure your design generates maximum capital appreciation while avoiding the prohibitive costs and stress of relocation.
Structural integrity isn’t negotiable. We translate complex building codes into precise technical drawings, managing everything from thermal efficiency to fire safety to ensure your project is fully compliant, legally sound, and built to last.
Every property offers unique opportunities for growth. From maximising narrow footprints with side-returns to creating expansive, multi-storey rear additions, we design bespoke extensions that harmonise with your home’s original architecture while radically improving its internal flow and functionality.

From modern glass-box designs to traditional brick built additions, we create bespoke rear extensions that redefine your home’s connection to the garden and maximise ground floor living space.
Rear ExtentionIdeal for Victorian and semi-detached properties, side extensions utilise underused alleyways to create spacious, open plan kitchen diners without sacrificing your entire rear garden.
Side ExtensionsA double-storey addition is the most cost-effective way to significantly increase your home’s footprint, allowing for expansive living areas below and additional bedrooms or master suites above.
Double Storey ExtensionsTransform your home’s curb appeal and functionality with a thoughtfully designed front extension, perfect for creating grand entrance halls, cloakrooms, or additional study space.
Front extensionsWhen ground space is limited, extending upwards provides a sophisticated solution. We specialise in vertical additions that integrate seamlessly with your existing structure to unlock new levels of living.

The cost of house extension can vary depending on the size, design, materials, and complexity of the project. At Brophy Riaz & Partners, House Extension plan services range between £995.00 + VAT to £3000 + VAT. We work closely with homeowners to design extensions that suit both their space and their budget, helping ensure the project is realistic from the start.
Some house extensions require planning permission, while others may fall under permitted development rights. This depends on factors such as the size, height, and location of the extension. Our team at Brophy Riaz & Partners can assess your property and handle the planning application process if permission is required.
There isn’t an exact timeline and all projects are different. Smaller extensions may take a few months to complete, while larger or more complex projects can take longer. We can help guide clients through each stage, from design and planning approval to construction, to keep the process as smooth and efficient as possible.
In some cases, you can extend your home without full planning permission under permitted development rights. However, there are strict limits on size, height, and placement. Brophy Riaz & Partners can advise whether your project qualifies and ensure all designs still comply with building regulations, to save you complications in the future.
Popular options include open plan kitchen extensions, rear extensions, and side returns that maximise natural light and improve layout. At Brophy Riaz & Partners, we design extensions that not only add space but also enhance how you live in your home.
Planning regulations in Birmingham can vary depending on the property type, location, and whether the home is in a conservation area or subject to other restrictions. Being based in Birmingham, Brophy Riaz & Partners has experience and relationships with local planning authorities and can guide you through the requirements, helping give your project the best chance of approval.
