OUR SERVICES
Pre-Purchase Architectural Services
If you are considering buying a property, our pre-purchase architectural services help you make an informed decision before you commit. We assess the site, planning potential, and development opportunities so you know exactly what can be achieved.
Our pre-purchase service can include any combination of the following:
• A virtual consultation with an experienced Project Director
• A pre-purchase design and planning workshop to explore your project ideas
• A site visit to assess the property in person
• A detailed pre-purchase feasibility and planning report
This service gives you professional insight into planning constraints, development potential, risks, and opportunities — helping you avoid costly mistakes and maximise the value of your investment.
Strategic Architectural Services for UK Planning Permission
Our strategic architectural services are designed to help homeowners, developers, and investors secure UK planning permission efficiently and with confidence. Working in line with RIBA Stages 1 to 6, we provide structured, fixed-fee packages that streamline the journey from early design through to planning approval and beyond. Each package is tailored to the specific requirements of your site and can cover feasibility studies, planning drawings, design development, and planning submissions (RIBA Stages 1–3), as well as technical design and tender documentation (RIBA Stages 1–4) where required.
These services are ideal for projects such as house extensions, loft conversions, new-build homes, change of use applications, and small developments. We assess local planning policies, permitted development rights, design constraints, and development potential to ensure your proposal has the best possible chance of approval.
All strategic architectural packages are offered on a fixed-fee basis, based on the scale and complexity of your project. This gives you clarity on costs while benefiting from professional architectural design, planning expertise, and full compliance with UK planning regulations.
Our goal is to make the planning process clear, efficient, and successful — helping you unlock the full potential of your property.
Full Architectural Services
We provide a complete, end-to-end architectural service that takes your project from initial concept to completed building. Our full architectural service follows RIBA Stages 1 to 6, ensuring a structured, professional, and fully managed process from design through to construction and handover.
From the earliest feasibility and design stages through to planning permission, building regulations, tendering, and on-site construction, we guide you through every key milestone. We coordinate consultants, manage technical design, and oversee the build to ensure your project is delivered to the highest standard, on time and on budget.
This service is ideal for new-build homes, major extensions, residential developments, and complex planning projects where professional architectural oversight is essential.
Our full architectural service is offered on a percentage-based fee, tailored to the scale, complexity, and value of your project. This gives you a fully dedicated architectural team focused on delivering a high-quality, well-managed, and successful outcome from start to finish.
