Sutton Coldfield has a varied mix of traditional family houses, larger detached homes, mature garden suburbs and development plots. Projects may need to address street character, Green Belt, trees, access, parking, conservation areas and neighbour amenity from the outset.
Hepburn Architects can support the project from early feasibility and planning strategy through to Building Regulations drawings and consultant coordination. The appointment is tailored to the property, approval route and information already available.

Sutton Coldfield includes the Four Oaks, Anchorage Road and High Street conservation areas. The High Street area has Article 4 controls, while Green Belt and landscape considerations can affect sites around the edge of the settlement.
Send the address, photographs, any existing plans and a short description of the space you need. We can discuss whether a measured survey and initial design study are the right first steps, then provide a written proposal for the agreed stages. An early conversation should cover your budget priorities and whether you intend to build in phases.
Yes. We can test how each option affects bedrooms, stairs, ground-floor living space, storage and the garden. The useful floor area, structural implications and approval route matter more than simply choosing the largest addition. The options to be drawn are agreed in the appointment.
Some extensions may be permitted development, but the dimensions, position, planning history and any conservation-area or Article 4 controls must be checked first.
Recognised areas include Four Oaks, Anchorage Road and High Street Sutton Coldfield. The High Street conservation area is also subject to Article 4 controls.
Green Belt policy is restrictive. Replacement homes and redevelopment proposals require a site-specific assessment of policy, openness, scale, landscape and the lawful existing building.
Yes. We can provide feasibility, design, planning submission support and Building Regulations drawings, coordinating structural and specialist information where required.
