Frequently Asked Questions
Not every project requires planning permission. Many home improvements, such as certain extensions, loft conversions and garage conversions, may fall under Permitted Development Rights. However, this depends on factors including the size of the proposal, your property’s location, and whether previous extensions have been carried out. As part of our architectural design service, we assess your project and advise whether planning permission is required before preparing the appropriate drawings and submitting any necessary applications.
Planning Drawings are prepared to obtain planning permission from your local authority and focus on the appearance, scale and impact of the proposed development. Building Regulations Drawings are a more detailed technical package used for construction and Building Control approval. They include construction details, specifications and structural information to ensure your project complies with current Building Regulations.
Yes. We provide architectural design and planning services for a wide range of residential projects, including single and double-storey extensions, loft conversions, garage conversions, open-plan living, structural alterations, kitchen extensions and complete home renovations. Every design is tailored to suit your property, your lifestyle and your long-term goals.
Yes. Where required, we coordinate structural engineering calculations, steel beam (RSJ) designs and the preparation of your Building Regulations package. By managing these services as part of the overall design process, we help ensure a smooth transition from concept through to construction while reducing delays and unnecessary coordination between multiple consultants.
Absolutely. One of the key benefits of working with Lewis Home Renovations is that we offer a complete design-and-build service. Once your architectural drawings, planning approval and Building Regulations package are in place, our experienced construction team can manage the entire build, providing dedicated project management from start to completion.
The cost depends on the size, complexity and scope of your project. Smaller design packages generally require less time than complete home renovations involving planning applications, Building Regulations and structural engineering. Following an initial consultation, we’ll provide a clear proposal outlining the services required and the associated costs, ensuring you understand the process before any work begins.
