One coordinated edition

England and Wales—clearly separated where it matters

The household and design questions are shared, while planning and building-control route prompts are separated where national guidance differs. Local policies, constraints and property facts still need checking for the actual home.

Built for homeowners, not professionals.
This is a plain-English decision and organisation aid. It helps you prepare a better brief, expose assumptions and choose proportionate evidence before committing money.

Use it in the right place

A guide supports the decision—it does not make it for you

This product does not inspect the property or provide architectural design, feasibility, planning, structural, building-regulations, cost, legal, Party Wall, project-management or safety advice. It does not confirm that work is permitted, buildable or suitable.

Where an uncertainty could change the proposal, cost, safety or approval route, obtain property-specific advice from the relevant authority or competent professional.
