We provide site access feasibility reviews to assess whether a site can be accessed safely and practically before land is promoted, purchased or designed. Our work focuses on identifying realistic access options, highway constraints and early risks so clients understand what is achievable from the outset.
A site access feasibility review is often the first step in understanding development potential. It provides clarity on new access arrangements, visibility, junction suitability and how a proposal may be viewed by the local highway authority.
What is a site access feasibility review
A site access feasibility review is an early-stage assessment of how a development site could be accessed from the existing highway network. It considers whether a new access is likely to be acceptable in principle and what constraints or design considerations may influence deliverability.
Our reviews are proportionate and evidence-led. They are not detailed designs, but they provide enough technical clarity to inform land decisions, planning strategy and early design work.
What a site access feasibility review includes.
Each site is different, but our access feasibility reviews typically consider:
-
Review of existing highway network and site frontage
-
Idenitifcation of potential new access locations
-
Visibility splay requirements and constraints
-
Speed limits and recorded traffic speeds from surveys if appropriate
-
Junction form and suitability
-
Early swept path feasibility
-
Pedestrian, cycle and public transport considerations
-
Physical constraints such as boundaries, levels, utilities, and third-party land
-
Initial highway standards and policy considerations
-
Concept stage drawings of access design options
We focus on presenting clear evidence that is proportionate and covers all key matters fully, without unnecessary analysis, keeping reports concise and proportionate.
When access feasibility advice is needed
Site access feasibility reviews are commonly required:
-
Before purchasing or promoting land
-
When testing development potential
-
For sites with constrained frontage or limited visibility
-
Where a new access onto a classified road is proposed
-
For rural sites or edge-of-settlement locations
-
When considering alternative access arrangements
-
Ahead of pre-application discussions
Early access advice can prevent costly redesign and reduce planning risk later in the process.
Our approach
We take a clear, structured approach to access feasibility:
-
Review site location and surrounding highway context
-
Identify realistic access points and constraints
-
Assess visibility and speed environment
-
Consider junction suitability and layout options
-
Review swept path feasibility where required
-
Provide clear, written advice on deliverability and risk
Our findings are presented plainly, focusing on what works, what does not and what may require further discussion with the highway authority.
Who we support
We provide site access feasibility reviews for a wide range of development types, including:
-
Residential sites
-
Strategic land promotion
-
Employment and commercial uses
-
Energy developments
-
Rural and edge-of-settlement sites
-
Mixed-use schemes
Our experience across England, Scotland and Wales gives us strong insight into highway authority expectations and regional policy differences.
