Residential Planning. Professional Design. Personal Service.

At KJB Design & Planning, we specialise in creating clear, council-ready plans for residential extensions and alterations. Whether you're adding space for a growing family, reimagining your home layout, or preparing for a full renovation, we’re here to make the process smooth, compliant, and creatively rewarding.

With over 25 years of hands-on experience in the building industry, KJB Design & Planning was founded to bridge the gap between practical build knowledge and professional design. We understand what works on site — and we bring that insight into every drawing we produce.

Our mission is simple: to help homeowners extend, improve, and make the most of their properties with cost-effective, planning-ready design solutions. Whether you're dreaming of a kitchen extension, a two storey extension, or a full renovation, we offer clear, compliant plans tailored to your needs and budget.

We’re based in Leicester and proud to serve homeowners across the region. We pride ourselves on clear communication, premium presentation, and a collaborative approach that puts your vision first. We have a strong foundation in UK building regulations and a commitment to approachable, trustworthy service, we make the planning process feel less daunting — and more exciting. Whether you're just starting or already have ideas in mind, we’ll guide you every step of the way.

Let’s bring your plans to life—with clarity, confidence, and a touch of design flair.
