Test whether the site can support the project.
Before drawings are fixed, we help clients understand what the site is likely to support and what evidence the local authority may ask for at planning. Early advice can help identify planning, environmental and compliance requirements before design decisions become difficult or costly to change.
Not sure if this is the right stage? If it is a home extension, refurbishment or one-off residential project, send us a message or give us a call and we’ll point you in the right direction.
Get in touchFeasibility-stage reports and advice
The pieces of work that most often happen at RIBA 0-2, delivered individually or as one coordinated feasibility package.
Before you commit to a scheme.
Early-stage sustainability strategy
A short strategy note setting out the likely energy, sustainability and carbon requirements for the scheme before drawings are fixed.
FeasibilityPlanning risk and policy review
A review of relevant local and national policy, including London Plan, borough SPDs and NPPF requirements, to flag what evidence may be needed at planning stage.
ScreeningPreliminary Environmental Risk Assessments
Early screening for contamination, ecology, noise and air quality, giving the project team a clearer view of whether these issues may affect layout, programme or cost.
ScreeningFlood Risk screening
Flood Zone check and initial drainage strategy view for sites in Flood Zones 2 and 3, or sites over the 1ha threshold.
ScreeningDaylight and sunlight, massing stage
Indicative daylight and sunlight checks on early massing options, helping identify constraints before the planning submission is developed.
ScreeningOverheating, early view
An initial review of Part O or TM59 overheating risk on early plans, helping shape glazing, orientation and shading strategy before the design freezes.
Set the strategy before the design is locked in.
The earlier energy, sustainability and environmental requirements are reviewed, the easier they are to build into the scheme. We help design teams understand the likely constraints, reports and policy expectations before drawings are finalised.
- Site and policy constraints identified early
- Energy and sustainability targets set from the outset
- Cost and programme implications understood before design moves on
What you get out of feasibility.
Common questions
Is feasibility work always worth doing?
For most projects beyond a straightforward small extension, it can be valuable. A written view on planning and environmental risks at RIBA 0-2 can help avoid redesign, late-stage evidence gaps or planning delays.
Do you produce fixed feasibility reports?
We tailor the output to the decision being made. Some clients need a short strategy note, while larger development sites may need a fuller environmental risk register or planning evidence review.
Can this feed into the planning submission later?
Yes. Early feasibility work can be used to shape the RIBA Stage 3 planning reports, helping maintain consistency rather than starting again.
What information do you need from us?
Useful information includes the site address, early drawings, planning notes, development type, intended use and any comments already received from the local authority or design team.
