Frequently Asked Questions

Can Claude Code create construction blueprints and materials lists?

Yes. The DIY Project Planner playbook generates detailed materials lists with exact quantities, dimensions, and cost estimates, plus step-by-step build instructions, tool checklists, cut diagrams, and safety notes for any home improvement or woodworking project.

What types of DIY projects can this playbook help with?

It covers furniture building (shelves, desks, tables), storage solutions (closet organizers, garage systems), outdoor projects (decks, planters, fences, sheds), home repairs (drywall, plumbing, electrical), and upgrades (lighting, hardware, trim work).

How accurate are the cost estimates for DIY projects?

The playbook provides itemized cost estimates based on typical retail prices. It recommends buying 10% extra materials to account for mistakes and waste, suggests budget alternatives when possible, and can adjust plans if you specify a target budget.
