Feasability  
& Consultation

Before drawings. Before applications.  Before commitment.

What is a Feasability Study?

The feasibility stage is where we step back and assess whether your project truly makes sense practically, financially, and in planning terms.

It’s about understanding what is possible on your site, what risks exist, and which options are worth pursuing before time and money are invested.

A feasibility study looks at the real potential of your property.

Rather than starting with design ideas, we begin by asking the right questions:

What can realistically be achieved?
What planning or technical constraints apply?
What approach offers the best long-term value?

For residential extensions, feasibility is where planning strategy, spatial thinking, cost awareness, and future-proofing come together.

It ensures the direction you move in is grounded, compliant, and worth pursuing.

What Comprises A Feasibility Study?

View Next Process

On-Site Assessment

We visit your property to understand its physical and contextual conditions. This includes access, neighbouring relationships, orientation, daylight levels, and the existing structure and services.

Context & Precedents

We review relevant local planning policies alongside previous approvals and refusals in the area. This helps shape a realistic planning strategy and understand what is likely  to be supported.

Legal Constraints

We identify key factors that may affect feasibility, such as conservation or heritage restrictions, flood risk, fire safety requirements, and permitted development limits. Addressing  these early helps avoid costly surprises later.

Spatial Design & Impact

We assess how proposed extensions would function within the existing building, considering circulation, daylight, usability,  and the relationship between new and  existing spaces.

Cost & Program Awareness

While detailed cost planning comes later, we provide an early sense check on construction complexity, likely cost ranges, and programme implications to align ambition with realistic expectations.

Ideally at the very start of a project, before drawings or planning applications. Early feasibility allows informed decisions to be made when changes are still simple and cost-effective.

No formal design drawings are produced at this stage. The focus is on strategy, viability, and direction rather than detailed design development.

No. While a feasibility study helps shape a realistic planning strategy, approval ultimately rests with the local planning authority.

You will receive an early sense check on likely cost ranges and construction complexity, but not a detailed cost plan, which is developed at later stages.

Yes. One of its key benefits is highlighting options that are unlikely to be viable, saving time, cost, and unnecessary redesign later.

You receive a clear assessment of project viability, strategic guidance on next steps, and the confidence to proceed, pause, or reconsider with clarity.
