What does masterplan layout involve?

Once the framework is agreed, the masterplan has to work as a place on the ground. We develop the layout: plot configurations, street and movement hierarchies and the arrangement of public and private space, testing options until the site reads as one coherent environment rather than a collection of development parcels.

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.

2. Concept Design

The design team explores options and massing, sets a sustainability approach, and prepares an order-of-cost estimate. Early conversations with planners may begin. By the end of this stage there's a preferred concept that meets the brief and budget.

Look at the whole process

Who does layout have to work for?

Layout at this scale balances many users at once: pedestrians, vehicles, servicing, future buildings and the spaces between them. Getting the structure right gives each subsequent plot design something solid to plug into.

High-level layout options

We test layout options and site organisation strategies, comparing how plots and routes can be arranged.

Movement and circulation strategies

Movement strategies, including access and circulation, ensure the site functions for users, vehicles and services.

Plot configuration and public realm

We configure plots and integrate public and private spaces so the masterplan supports both individual buildings and the wider environment.

How are layout options tested?

Against the people and demands that will use them: pedestrian and vehicle movement traced through the plan, servicing and access checked for every plot, open space assessed for how it will actually be used and alternative arrangements compared until the structure holds up rather than merely looks resolved.

A project we have worked on

Crematorium & Cemetery, Brentwood

Ecclesiastical
New Build
Public Sector

Set within beautiful, manicured grounds, the crematorium and cemetery provide a peaceful setting for remembrance and quiet contemplation. Planning consent was secured, with technical design progressed to Tender.

FAQs

What does spatial planning decide at masterplan scale?

+

The position and shape of development plots, the movement network, the location and character of open spaces and how public and private realms meet. It is the skeleton every later design attaches to.

How do movement strategies shape the layout?

+

Fundamentally. Desire lines, access points, servicing routes and parking strategy define the street structure, and the street structure defines the plots.

How flexible should plots be?

+

Flexible enough to absorb market and brief changes over the delivery period, defined enough to guarantee the quality of streets and spaces. Parameter drafting strikes that balance.

How is public space distributed across a site?

+

Where it earns its keep: on key routes and gathering points rather than leftover corners. Quality and location matter more than raw quantity.

Do you test layouts against technical requirements?

+

Yes. Highways geometry, servicing, drainage strategy and utilities corridors are tested against the layout as it develops, with the relevant engineers involved.

What outputs does this stage produce?

+

Layout options and a preferred framework plan, movement and space hierarchy diagrams and plot schedules, coordinated with the phasing and planning strategy.

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.
