Our Projects
Our projects include adding extra bedrooms through two-storey extensions or loft conversions, and creating more ground floor space with single-storey rear and side extensions. These often provide enhanced kitchens, utility rooms, home offices, playrooms, or additional lounges—spaces designed around how your household lives and works.
We’re also experienced in developing detailed proposals for small kitchen extensions, loft redesigns, and attic layout plans. Every set of drawings we produce is carefully tailored to your specific goals and grounded in practical construction knowledge to ensure a smooth handover from design to build.
Planning Permission
Navigating the planning system can feel daunting, but we’re here to make it simple. We manage the entire process from handling the submission of the planning application, communicate directly with the planning officer, and make any amendments required during the process.
With extensive experience working within the Sheffield planning system, we’ve submitted hundreds of successful applications for home extensions, loft conversions, and garage projects. We understand local planning policies and what Sheffield city council is likely to support. Our designs are carefully considered to give your project the best chance of gaining approval first time, reducing delays, redesigns, and unnecessary costs.
Building Regulations
We provide detailed construction and building regulations drawings to support accurate pricing and smooth on-site delivery. These technical plans ensure full compliance with building regulations approval, covering key areas such as fire safety, structural integrity, insulation, ventilation, and drainage.
We take care of everything, including building control approval submissions and responding to queries raised during the process. If you project involves drainage alterations, we’ll also handle applications to the water authority to ensure all works meet statutory requirements.
Why Choose Us?
From your initial consultation through to final approval, we provide a structured, supportive service rooted in local knowledge and technical expertise. We’re committed to designs that deliver real value—enhancing how you live without overcomplicating the process.
Whether you’re planning a loft upgrade in Sheffield, mapping out home extension plans, or designing a bespoke attic layout, we guide you through each step with clarity and care—delivering spaces that are functional, cost-effective, and built to last.
