What does a feasibility study test?

A feasibility study answers the question every project starts with: what can this site realistically support? We test capacity, layout and massing options against planning policy, site constraints and operational need, comparing scenarios side by side so the strengths and compromises of each are visible before money follows.

Where Pre-Planning & Feasibility sits in the RIBA process

1. Preparation & Briefing

2. Concept Design

7. Use

3. Spatial Coordination

6. Handover

5. Manufacturing & Construction

4. Technical Design

0. Strategic Definition

This is the "should we build?" moment. The team clarifies goals, budget, risks and constraints, explores options (including non-build solutions), and forms the business case. The outcome is a confirmed set of client requirements and a go/no-go decision.

1. Preparation & Briefing

All the groundwork happens here: site information, surveys, statutory context and stakeholder needs are gathered, and the Project Brief and outline programme are agreed. Procurement and planning strategies are sketched so everyone knows the road ahead.

Look at the whole process

How are studies scaled to the decision?

Studies are scaled to the decision: a rapid test-fit to sift a portfolio, or a fuller study to underpin a board paper, funding bid or acquisition. Either way, the output is evidence that decisions can stand on.

Why do Pre-Planning & Feasibility with AEC architecture?

Capacity studies and test-fit layouts

We test how a site can be used at a practical level, modelling capacity and proposing layouts that respond to client objectives.

Massing studies and site optimisation

Massing exploration and site optimisation help clients understand scale, form and how to maximise value within site constraints.

Massing studies and site optimisation

We compare development scenarios side by side, including density and unit mix considerations, so informed decisions can be made early.

What does a feasibility study give you?

Evidence in a form decisions can rest on: scenarios compared side by side, capacities stated with their assumptions visible, risks named rather than smoothed over and a recommendation you can interrogate. Whether it supports a board paper, a bid or a purchase, the study exists to be relied upon, not admired.

FAQs

What does a feasibility study include?

+

Capacity and test-fit layouts, massing options, an assessment against planning policy and constraints and a comparison of scenarios with a recommendation. Indicative areas support early cost advice from your cost consultant.

How long does a feasibility study take?

+

Rapid test-fits can be produced in days; fuller studies typically run two to six weeks depending on site complexity and the number of scenarios tested.

What information do you need to begin?

+

Site boundaries and any existing surveys or drawings, plus your brief and objectives. Where information is missing, we work from mapping and site visits and flag what should be commissioned.

Are feasibility layouts the final design?

+

No. They are honest tests of capacity and arrangement, not resolved designs. Their job is to support the go or no-go decision and set parameters for the design stages that follow.

Can studies support funding bids or business cases?

+

Yes, frequently. Feasibility material provides the tested options, areas and visuals that give funders and boards confidence the proposal is grounded.

What if the study shows the site does not work?

+

Then it has done its job. Knowing a site cannot meet the brief before acquisition or design spend is one of the most valuable outcomes feasibility work can deliver.

What our clients say

From schools to homeowners, we work closely with every client to deliver thoughtful, lasting architecture here’s what they’ve said about working with us.

Sarah Mitchell
Headteacher, Hollowbrook primary

AEC understood exactly what our school needed a space that was calm, practical, and inspiring for students and teachers alike. The whole process felt collaborative from day one, and the end result has had a real impact on daily school life.

James Carter
Private homeowner, Cambridge

Working with AEC was seamless. They listened carefully, challenged our thinking in the right ways, and delivered a design that just works — light, functional, and surprisingly cost-efficient. We couldn’t be happier with the result.

Ravi Patel
Director, Ashore housing development

AEC brought clarity and creativity to a complex residential scheme. Their technical knowledge and attention to detail kept the project on track and their team were genuinely great to work with.
