ArchLens

For Architectural Practices

Feasibility triage in minutes, not billable hours

Before you quote a fee, know the planning route, the policy position and the submission requirements. ArchLens runs the checks you'd do manually — against the actual GPDO limits, your client's council's actual adopted policies and the England Approved Documents — and cites every finding to its source.

The Workflow

How Practices Use ArchLens

1

New Enquiry Arrives

Enter the address and proposal in a guided wizard. The site's conservation area, Article 4, listed building and flood zone status are verified against official government datasets automatically — not just taken on trust from the client.

2

Assessment in Minutes

The rules engine determines the likely route — permitted development Class A–H or a planning application — checks the proposal against adopted local policy where a library exists, and lists the council's submission requirements for this project specifically.

3

Quote & Deliver Informed

Scope the fee knowing the route and the risks. When the job proceeds, generate a structured Planning Statement draft from the same verified findings — then refine it in Word under your own name.

Under the Hood

Findings You Can Verify, Not Vibes

You wouldn't accept "the AI thinks it's fine" from a junior — you shouldn't accept it from software. Every ArchLens conclusion is traceable.

GPDO Route Engine

Deterministic Class A–H logic with per-limit test rows — depth, height, eaves, volume, boundary — each citing the exact GPDO provision, assessed against your dimensions.

Council Policy Engine

Adopted Local Plan policies and SPD standards held in a versioned, citation-locked library — results show the measured value against the published standard, with the document and paragraph named.

Approved Documents Engine

Building Regulations checks across structure, fire, thermal, ventilation, drainage and access — each conclusion traceable to its Approved Document paragraph.

Verified Site Constraints

Conservation areas, Article 4 directions, listed buildings and flood zones checked against official government datasets at the property's actual coordinates.

Drawing Pack Cross-Check

Upload the PDF pack; dimensions and construction details are extracted per sheet and cross-checked against the questionnaire — discrepancies flagged with both values shown.

Submission Checklist

The documents your client's council actually requires for this proposal — validation requirements resolved per authority and per project, not a generic list.
