How is concept design used before planning?

At pre-planning stage, concept design is a testing tool. We produce indicative floorplans, spatial arrangements and high-level design strategies that show how a brief could sit on a site, aligned with planning policy from the first line. Early visualisations are added where seeing an idea is the fastest way to judge it.

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

What decisions do early concepts inform?

These concepts inform decisions that precede full design: whether to buy, what to brief, what to take to a pre-application meeting. They are deliberately light and honest, giving a realistic picture of potential without the cost of developed design.

Why do Pre-Planning & Feasibility with AEC architecture?

Early-stage design proposals

We develop initial concepts that explore site potential and start to shape how a project might be realised.

Indicative floorplans and spatial strategies

Indicative layouts test how the brief can sit on the site and how spaces relate to one another at concept stage.

Indicative floorplans and spatial strategies

We align early design thinking with relevant planning policy, supported by visualisations where they aid decision-making.

How detailed is pre-planning concept work?

Deliberately light. The drawings carry enough to judge whether an idea works on the site and against policy, and no more, because at this stage the ability to change direction cheaply is worth more than polish. Detail is added when a direction is chosen, not before.

A project we have worked on

New College Swindon (Animal Centre)

Replacement / Redevelopment
College

Replacement animal centre modernises teaching rooms and adds welfare areas for viewing and care. AEC delivered end-to-end: secured funding, achieved planning, obtained Building Regulations approval, and provided administrative support.

FAQs

How does pre-planning concept design differ from full concept design?

+

It is lighter and decision-focused: enough design to test potential and support early conversations, without the resolution of a full concept stage. If the project proceeds, it feeds directly into formal design.

What do the outputs look like?

+

Indicative plans, arrangement diagrams, massing sketches and short supporting narrative, with visualisations where useful. Enough to see the idea, not enough to over-invest in it.

Can these concepts be used in pre-application discussions?

+

Yes, that is one of their main uses. A clear indicative scheme lets planning officers respond to something concrete, which produces far more useful feedback.

How closely do you follow planning policy at this stage?

+

Closely enough that concepts are realistic. Scale, use and character are set within a credible reading of policy so early decisions are not built on schemes that could never be consented.

What does this stage cost relative to full design?

+

A small fraction. The point is to spend a little to test the idea before spending a lot to develop it, and the work is not wasted if the project proceeds.

What happens if the concept confirms potential?

+

The project moves into feasibility refinement or straight into formal concept and developed design, with the early work carried forward rather than repeated.

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.
