We prepare initial access concept sketches to illustrate how a site could be accessed at an early stage. These sketches provide a clear visual representation of feasible access arrangements, helping clients, designers and authorities understand what is achievable in principle before detailed design work begins.
Initial access concept sketches are particularly valuable during feasibility, site promotion and pre-application stages, where clarity of intent can shape decision making and avoid misalignment later.
What are initial access concept sketches
Initial access concept sketches are high-level drawings that show potential access locations, junction forms and key geometric principles. They are not detailed engineering designs, but practical tools used to test feasibility, communicate intent and support early discussion.
These sketches are commonly used to support land decisions, masterplanning, pre-application engagement and early highways advice, providing a shared understanding of access possibilities and constraints.
Our initial access concept sketches are tailored to each site and typically include:
-
Indicative access locations and alignment
-
Initial junction form options (priority T-junction, ghost island, roundabout or signals)
-
Carriageway widths and basic geometry
-
Visibility splay assumptions
-
Footway and cycle connections in principle
-
Key constraints affecting access layout
-
Concept level drawings (sketches) including clear annotations explaining design intent
The value of initial access concept sketches lies in turning abstract access ideas into something tangible that can be tested, discussed and challenged early. By illustrating feasible access arrangements at an early stage, we help clients understand what is realistic, where flexibility exists and where constraints may influence design. This reduces reliance on assumption, supports more constructive dialogue with highway authorities and allows access principles to be agreed before time is invested in detailed design. It also helps ensure that later technical work builds on a sound, credible starting point rather than needing to be reworked.
When initial access concept sketches are needed
Initial access concept sketches are commonly prepared:
-
At feasibility or pre-purchase stage
-
During strategic land or site promotion
-
To support pre-application discussions
-
When testing alternative access options
-
Ahead of masterplanning or layout design
-
For constrained or sensitive access locations
They are particularly useful where access feasibility is likely to be a key consideration in planning.
Our approach
We take a clear, proportionate approach to early access sketching:
-
Review site context and highway environment
-
Identify feasible access locations
-
Test appropriate junction forms in principle
-
Consider visibility and geometric requirements
-
Prepare clear, annotated sketches
-
Provide written advice on feasibility and risk
Our focus is on clarity, realism and usefulness, ensuring sketches genuinely support decision making.
Who we support
We prepare initial access concept sketches for:
-
Residential developments
-
Strategic land and site promotion
-
Commercial and employment uses
-
Retail and leisure schemes
-
Energy and infrastructure projects
-
Rural and edge-of-settlement sites
Our experience across England, Scotland and Wales provides strong insight into varying highway authority expectations and design standards.
