Services & professional fees
Spaces designed for the way you want to live
Whether it’s opening your kitchen to the garden, creating space for a growing family, or unlocking the development potential of a site, thoughtful design can transform how a property works.
Our aim is to create spaces that feel calm, practical and beautiful — homes you genuinely enjoy living in.
St Albans & Hertfordshire focus
Planning permission that respects your home and its setting
We regularly support homeowners across St Albans and surrounding villages. Many of these properties sit in conservation areas or have established character that needs to be handled with care.
Whether you are exploring a rear extension, side extension, loft conversion or garden studio, we align new proposals with the established rhythm of your street and the expectations of the local planning teams.
Local insight, applied to your project
Understanding of how St Albans City & District Council approaches extensions, rooflines and rear projections.
Awareness of typical officer concerns: impact on neighbouring amenity, overlooking, bulk and design language.
Experience with period terraces, Victorian and Edwardian homes, and properties set within conservation areas.
Balanced advice on what can be delivered under permitted development versus full planning applications.
Ability to reference relevant local precedent in your planning submission.
Next step
