About us
Rob and Carly Seward live and work in Horsforth, North Leeds. They founded Yorkshire Property Design Services in June 2020 after many years working in the architectural and property sectors. Their goal is to provide a professional, approachable architectural design service in North Leeds and surrounding areas.
Rob has over 20 years' experience as a Senior Architectural Technologist and is a member of the Chartered Institute of Architectural Technologists (CIAT). Carly has worked in the local property industry for 15 years — firstly in sales and lettings, and latterly in property auctions.
Together, they deliver the best customer service alongside high-quality drawings and plans, with a clear and transparent pricing structure.

The process
We visit your home to discuss your ideas, give suggestions and explain the process. We then prepare a written quotation inclusive of all fees. Free for homeowners — prospective purchasers and developers are charged £50/hr + travel.
Once you accept the quotation, we arrange a survey at a mutually convenient time. This takes one to three hours depending on the project. We then produce your existing drawings and issue an invoice — paid before we proceed.
Working with you, we produce sketch designs and proposal drawings for your approval. Up to three sets of revisions are included — any additional revisions or work beyond the agreed scope is charged at £50/hr.
We complete all required forms and submit your planning application to Leeds City Council or Bradford Council. We liaise with planners throughout and keep you informed. Decisions typically take up to eight weeks.
Once planning is approved, we produce detailed construction drawings showing exactly how your project should be built — covering structure, thermal performance and fire safety in line with building regulations.
We complete all relevant paperwork and submit your application to building control, dealing with the application through to full or conditional approval. Structural calculations from a structural engineer may also be required.
Up to three sets of revisions to the construction drawings are included in your quotation. Any further revisions or changes beyond the agreed scope will be charged at £50/hr.
With planning approved and building regulations in place, you're ready to go to tender and appoint a builder. We recommend asking friends or neighbours for recommendations, or using Facebook community groups for local referrals.
