Where new buildings, extensions, or other structures are proposed close to trees, designers may need tree information to help assess foundation requirements.
Flow Tree Consultancy provides tree surveys for foundation design, supplying relevant arboricultural data for structural engineers, architects, homeowners and self-builders working on development or extension projects across Hampshire, Surrey, Sussex, Kent and London.
This service is suitable where tree information is needed to support foundation design calculations, including projects where NHBC guidance or warranty requirements are being considered.
When a foundation design tree survey may be needed
A tree survey for foundation design may be needed where new buildings, extensions, or other structures are proposed close to existing trees, removed trees, significant shrubs, or hedgerows.
It may be requested at design stage by a structural engineer, architect, warranty provider, or building control body where tree information is needed to help assess foundation requirements.
This can include situations where:
-
a new dwelling or extension is proposed near trees
-
building control has requested tree information before foundation design is confirmed
-
a structural engineer needs tree data to inform foundation depth calculations
-
NHBC guidance or warranty requirements need to be considered
-
trees or hedgerows have been removed and may still be relevant to ground conditions
-
proposed planting needs to be considered as part of the landscape design
What the survey includes
The survey records the tree information needed by designers when assessing foundation requirements. This usually includes:
-
tree species
-
current tree height
-
expected mature height of the species
-
water demand classification
-
tree positions shown on a scaled plan
-
relevant tree data presented in a clear schedule
The output is provided as a short report, including a brief introduction, survey methodology, tree schedule, and accompanying scaled plan. The plan can also be provided in DWG format, allowing designers to accurately measure distances between specific trees and proposed foundations when assessing foundation requirements.

Supporting design, not designing foundations
Flow Tree Consultancy provides the relevant tree information needed to assist the foundation design process.
The final foundation design, including foundation depths, engineering specification and compliance with warranty or building control requirements, remains the responsibility of the appointed designer, structural engineer, building control body, warranty provider or other relevant professional.
Foundation design tree surveys and BS5837 planning surveys
A tree survey for foundation design is different from a BS5837 tree survey prepared for planning applications and development projects.
A foundation design tree survey focuses on tree data needed to help assess foundation requirements. A BS5837 planning survey is usually prepared to inform planning, site layout design, arboricultural impact assessment and tree protection during demolition or construction.
Where both issues are relevant, Flow Tree Consultancy can provide the foundation design tree survey separately or alongside a BS5837 tree survey for planning and associated reporting.
Information needed for a quote
To provide a clear quote, the most useful information is:
-
the site address
-
an existing site plan, such as an architect’s drawing, topographical survey, or OS MasterMap-based plan
-
the proposed layout or extension plan
This helps identify the likely survey area, the number of trees to be considered, and any site access requirements.
