Our experience spans thousands of London projects, so we know every council pattern, refusal trap and terrace detail. The result is a repeatable workflow that delivers your planning permission drawings within 5 business days of our site visit — without the overhead or delays of a traditional practice.
3D laser survey, CAD drawings and Planning Portal submission — all handled by a 5-star rated London studio.
The London planning & drawings market hasn't moved in 20 years. We rebuilt it from scratch.
Honest, line-by-line comparison versus how planning normally gets done in London.
| Service Metric | The Old Way | hatch. |
|---|---|---|
| Site Survey | 2 hours of manual, error-prone tape measuring — or a camera scan with a 2-week lag | 45-Min Precision 3D Laser Cloud Scan |
| Turnaround Time | 4–8 weeks for initial concept ideas, stuck in high-street or corporate queues | Plans within 5 business days of site visit |
| Design Process | Reinventing the wheel on every property, or multi-stage consultative back-and-forth | Pre-mapped London terrace archetypes |
| Pricing Model | Percentage of build cost or opaque corporate packages — always unpredictable | Transparent fixed-fee studio pricing |
| Planning Submission | You chase the agent for weeks, or it lands in a generic national portal | Lodged directly with your LPA on Planning Portal |
