Brentwood planning permission
Planning permission is one of the most challenging aspects of building a home extension, or at least can be depending on how experienced your architect is with Brentwood council. Now, architectural design in Brentwood differs from other areas, as the local council have their own specific requirements and sometimes view things differently to other councils. With years of experience working in Brentwood, we understand exactly what it takes to gain approval and ensure your project meets all necessary standards.
While many single-storey extensions in Brentwood fall under permitted development rights and may not require planning permission, larger projects like loft conversions or work on listed buildings often do. That’s where our expertise comes in. Kirkwood handles every step from start to finish.

What is Architectural Design?
Architectural design is the process of planning and creating a home extension that meets your family’s needs, doesn’t break the bank, and complies with local regulations. When it comes to architectural design in Brentwood, it is essential to consider the unique requirements of the area. We have to try to keep the neighbours happy, follow planning guidelines, and take the character of the surrounding neighbourhoods into consideration.
Architectural design in Brentwood can be a great investment, whether you do the build or just sell the property with approval for an extension. Architectural design creates a clear plan of the internal layout for the existing and proposed. This means you can get all those ideas that are building up in your head out onto some paper. This might sound small, but believe me, it brings huge relief and frees up headspace for the next steps. Our architectural design process ensures every detail is carefully planned, from maximising natural light to creating layouts that enhance your daily life, all while adhering to Brentwood’s building regulations.
