SJI Designs Ltd

Your Vision, Visualised: Architectural Excellence in Nottinghamshire

Whether you are a homeowner looking to extend or a developer planning a 36-home site, we provide a seamless, "one-stop-shop" experience. At SJI Designs Ltd, we believe professional architectural services should be accessible and transparent. That is why we operate a unique pay-as-you-go service for planning and building regulation applications, ensuring you only pay for the stages you need, when you need them.

Based in Mansfield and serving the wider Nottinghamshire and Derbyshire areas, we bridge the gap between technical expertise and creative design. We don't just draw plans; we help you decide whether to "extend or move" by providing market appraisals alongside architectural advice.
