Designs and feasibility
We design house extensions across London and the home counties, considering layout, light, planning requirements, and buildability from day one. Each project is approached holistically, from early design through to clear construction information.
Understanding the site
Every property has its own opportunities and constraints, planning policy, access, neighbours, rights of light, structure, or heritage.
Feasibility work reviews these early, so decisions on scale and layout are informed from the outset. It reduces redesign, avoids wasted spend, and keeps proposals realistic.
Design direction, not overcommitment
Early design should provide clarity without forcing unnecessary detail.
We use concept layouts, massing studies, and option testing to compare approaches and understand trade-offs, space, cost, planning risk, and long-term value. Where useful, we test multiple routes to identify the strongest overall outcome.
Planning awareness from day one
Feasibility is closely linked to planning strategy.
Knowing whether a project is likely permitted development, requires full planning, or would benefit from pre-application advice shapes smarter design decisions. This keeps proposals aligned with policy expectations and improves the odds of a smooth approval process.
Budget reality checks
A feasibility exercise also provides an early sense check on cost and value.
While detailed construction pricing comes later, early design decisions have a significant impact on build complexity and overall budget. Addressing these considerations at feasibility stage helps ensure that proposals remain commercially and practically viable.
A confident starting point
By the end of this stage, you should understand:
-
what’s realistically achievable on your site
-
the likely planning route
-
the key risks and constraints
-
whether to proceed, refine, or pause
That clarity helps projects move forward with confidence, or stop before unnecessary costs are incurred.
Start a project
Early advice can make all the difference. If you’re considering a project, we’re happy to discuss feasibility, constraints, and next steps.
