Architectural design service

At A7 Studio, we provide a complete architectural service—from initial sketches to detailed designs and construction. Our dedicated team takes care of every step, paying close attention to detail no matter the project’s size. We prioritize not only how things look and work but also making the entire process smooth and enjoyable for our clients.


A house extension is a fantastic way to enhance your living space and meet the evolving needs of your household. Whether you’re looking to create a larger kitchen, add a new bedroom, or build a versatile living area, a well-designed house extension can significantly improve your home’s functionality and overall appeal. It allows you to maximize your existing property, providing the extra room you desire without the need for relocation. From modern designs to traditional styles, a thoughtfully planned house extension can seamlessly integrate with your existing structure while adding value and comfort to your living space.



A loft conversion is a transformative solution to unlock untapped potential within your home. By converting your underutilized loft space, you can add valuable living space without the need for a major extension. This versatile upgrade opens up opportunities to create an additional bedroom, a cozy home office, or a stylish recreational area. A well-executed loft conversion not only maximizes your property’s square footage but also adds a unique touch to your home. Whether you envision a contemporary loft design or a more traditional style, this renovation option provides a cost-effective way to enhance both the functionality and aesthetics of your living space.


Apart from the architectural facets, we provide interior design services to fashion cohesive and visually captivating interiors that enhance the overall architectural design.

We guide clients through the intricate process of planning permissions and submissions, securing all requisite paperwork and approvals for the seamless and legal advancement of your project.

Our Design

We carefully create each design based on your specific needs and budget, considering how you want to use the space.

We also take a close look at the challenges and possibilities of the site and its surroundings. This way, every project we take on becomes a perfect mix of your ideas, budget, and the unique features that make each space special.

We’re not just focused on building structures; we want to create spaces that improve your life. We believe that architecture is about more than just constructing buildings – it’s about designing environments that inspire, support, and enhance the human experience.

Through thoughtful design and careful execution, we aim to turn your vision into spaces that truly make a positive difference in your everyday life.

Our Drawings

Planning drawings are at the heart of a successful planning application. At our firm, we prioritize excellence in every drawing we create. Our drawings not only meet the required standards but also provide comprehensive information to articulate the development proposal. This ensures a thorough assessment by the planning department, internal and external consultees, as well as neighbors and local interest groups.

Our commitment to accuracy is unwavering. All plans are meticulously drawn with a conventional metric scale, maintaining a suitable standard. To enhance clarity, we present proposed and existing drawings side by side, both using the same scale. This approach aims to facilitate understanding for all stakeholders involved in the planning process.

Choose us for your architectural needs, where precision meets clarity in every drawing.

A damp-proof course serves as a protective barrier to prevent moisture from rising up the walls of a building. Different types of damp-proof courses are available, but they are typically not used in combination.

The Building Regulations specify a minimum gap of 150mm (equivalent to 2 brick courses) between the Damp-Proof Course (DPC) and the ground or any paving. This is considered ‘Best Practice.’ Nevertheless, certain circumstances may arise where adhering to this regulation is not feasible or practical.

When there is no existing damp-proof course in position, or if the current barrier has failed for any reason, the building becomes susceptible to issues related to rising damp.

Insufficiently ventilated sub-floors pose an elevated risk of timber decay, stemming from potential rot or insect infestation due to inadequate airflow. Effective ventilation is crucial to expel warm, moist air from the sub-floor, mitigating the likelihood of condensation forming on the timber structures.

If a property is constructed on clay subsoil, it should undergo continuous monitoring for structural cracking. As global warming continues to impact weather patterns, the heightened risk of structural issues arises due to movements resulting from the changing volume of the subsoil.

In newly constructed properties, it is now mandatory for all rooms opening onto a hallway to have FD30 rated doors installed. This requirement is implemented to enhance the safety of occupants in case of a fire. While not obligatory for older properties, it is recommended that owners consider upgrading internal doors to align with these regulations. In instances of significant alterations to a property, the new requirements may also become applicable. If there are no plans to upgrade doors for compliance, it is essential to ensure that appropriate measures are in place to facilitate safe escape in the event of a fire.
