Expert Residential Architects for Birmingham House Extensions

Welcome to ADM Studio, your local specialists in home extension design across Birmingham and the West Midlands. Whether you’re dreaming of a light-filled kitchen extension, an extra bedroom, or a reimagined living space that transforms the way you live, our award-winning team is here to bring your vision to life—with clarity, creativity, and expert guidance at every step.

Why Choose ADM Studio for Your Home Extension Design?

Adding space to your home should feel exciting—not overwhelming. At ADM Studio, we take the stress out of the process by handling everything from initial concept designs to planning permission and technical drawings. With years of experience designing beautiful, functional extensions for homes across Birmingham, we know what it takes to make your project a success—on time, on budget, and with total confidence.

Tailored Extension Design Solutions for Every Home

Every family, every lifestyle, and every home is different. That’s why we never take a one-size-fits-all approach. Instead, we listen closely to what you need and develop a design that reflects your personal taste, complements your existing home, and enhances your day-to-day living.

Whether it’s a single-storey rear extension to open up the kitchen and dining area, a side-return that maximises narrow plots, or a double-storey addition for growing families—we’ve got the expertise to turn your ideas into a thoughtfully designed space you’ll love.

Our Extension Design Process

We’ve refined our design process to keep things straightforward and collaborative from day one:

  1. Initial Consultation
    We start with a free consultation to understand your needs, explore ideas, and assess the scope of your property. This is where your vision begins to take shape.
  2. Measured Survey & Existing Plans
    Once appointed, we conduct a measured survey to create accurate floor plans and elevations of your existing property. This forms the base for all design work.
  3. Concept Design & Iteration
    Our team develops a tailored extension design based on your requirements, style preferences, and budget. We then go back and forth with you—refining and adjusting—until you’re completely satisfied.
  4. Planning & Building Regulation Drawings
    From there, we produce all the documentation needed to secure planning permission, including design and access statements, site plans, and location maps. If required, we’ll also handle listed building consent and party wall notices.
  5. Technical Detailing
    We can prepare detailed construction drawings to support your builder, covering everything from structure to finishes, energy efficiency, and beyond.

Planning Permission? We've Got It Covered

The planning system in the UK can be complex—especially in conservation areas or when adding height and depth to existing properties. ADM Studio has an excellent track record of navigating Birmingham’s planning policies with success. We’re meticulous in our approach, identifying potential planning hurdles early and crafting proposals that align with both your goals and local regulations.

Many of our home extensions fall within permitted development rights, but where full planning is required, we take the lead in submitting and managing your application to ensure the smoothest path forward.

Built to Last – Inside and Out

At ADM Studio, we care just as much about the practicality of your extension as the look and feel. Our technical detailing and understanding of materials means we design for both beauty and buildability—ensuring your extension doesn’t just look amazing but performs well and stands the test of time.

We work closely with trusted builders, engineers, and consultants to ensure your project runs smoothly during the construction phase. We’re also happy to liaise with your chosen contractor to clarify drawings and offer on-site design support where needed.

We had a great experience working with Gagan and his team @ ADM Studio Ltd. From the very beginning, the team were approachable, professional, and really easy to deal with. They took the time to understand what we wanted and offered helpful ideas to improve the design along the way. Communication was clear and consistent throughout, which made the whole process much less stressful. Any changes or questions we had were dealt with quickly, and they guided us confidently through the planning stages. Overall, we’re really happy with the service and the final result. We’d definitely recommend ADM Studio Ltd to anyone looking for a reliable and knowledgeable architectural team.

We have engaged with Gagan & his team for a Pre-Application prior to submitting for full planning, the site of the proposal is challenging. Gagan has been attentive throughout the process thus far & we have been impressed with the attention to detail in the pre-app process, the documents produced at every stage have been thorough, we await decisions from the local authorities. I have no hesitation in recommending ADM.

We used this firm to draw up plans for two new build houses. The team were very professional, helpful and skilled in their work. I would certainly use the services provided again.
