Architectural designers for residential
projects in London
Experience architecture with clarity, patience and precision...
Typical response within 24 hours (Mon–Fri).
We design extensions, loft conversions, and renovations for homeowners across London boroughs and the surrounding home counties who value precision, detail, and a thoughtful, creative approach to design.
House extensions
We design rear and wrap-around house extensions that maximise light, improve circulation, and respect neighbouring context across London suburbs.
Loft conversions
Thoughtful loft conversion design focused on light, structure, and practical living space, with planning and build considerations addressed early.
Whole house remodels
Integrated whole-house remodel design that improves layout and usability, informed by planning requirements and construction realities.
Building regulations shape how a project is built, not just how it looks. We produce clear, coordinated drawings that address structure, fire safety, insulation, and construction detail early, helping avoid delays, redesigns, and uncertainty once work is on site.

Understanding how residential projects are funded
Many residential projects are shaped as much by funding constraints as by design ambition. Understanding how projects are typically financed helps set realistic expectations and avoid unnecessary delays later on.
This helps you choose a realistic route: savings, remortgage, staged works, or lender-led timelines.

Planning approved first time
HOBBS ARC made the whole process of extending our house suprisingly straightforward. From the initial design through to planning approval, the team were on top of everything: clear, communicative and meticulous.

Rear extension + kitchen remodel
Their attention to detail was exceptional, and they were always available to answer questions. The final space feels light, modern, and beautifully integrated with our existing home. We couldn't be happier with the result.
