12×16 Storage + Hand-work Shed
Ask each provider to price the same storage-and-hand-work outcome: usable interior, clear entry, bench responsibility, site preparation, delivery, finishes and service needs.

Build, kit or delivered shed · buying guide
Compare the same finished job before comparing prices.
Start with your measured layout and required outcome. Then ask who supplies, delivers and installs each part. A build-path label tells you which questions to ask; the written offer establishes the actual scope.
Use one project brief for every offer
Open-front Bike Storage Case Study
Free drawings do not make materials or labor free. The author’s materials list, cut list and build sequence are distinct from a supplier quote or a site-specific design.
Open tool with this project context →Record one offer at a time. Keep competing offers separately; never add them as parts of one total. Blank means not quoted. Enter zero only for an explicitly included or no-charge item.
Compare real resource packages →Four ways to obtain it. Four sets of questions.
DIY / self-managed
Can I arrange the design, material purchasing, site work and assembly required by this specific project?
Record the work you will do, the equipment or help you need and the tasks you will commission. Your own time and unquoted work do not disappear from the decision.
Kit
Exactly which components, openings, instructions and installation services come with this kit?
Confirm the packages can reach the site and identify excluded support, roofing, finish or assembly items in the actual offer. Do not assume every kit includes the same parts.
Prefab / delivered assembled
Can the supplier deliver and place this exact building at the measured location?
Request the transport dimensions and placement method, then confirm the required site preparation. The nominal floor size does not describe the transport envelope.
Contractor / on-site build
Who owns the design, site preparation, construction scope and required local review?
Request a written specification with the usable interior and clear opening your layout needs. Identify exclusions, handoffs and the process for changes before comparing the quote.
Fictional scope example · USD
A lower shell price can have a higher known subtotal.
These invented amounts demonstrate addition only. They are not current shed prices, quotes or an estimate for your project. Compare the same specification and assign every included item once.
| Scope | Offer A | Offer B |
|---|---|---|
| Shell | $4,000 | $4,700 |
| Delivery | $600 | Included · $0 extra |
| Assembly | $500 | Included · $0 extra |
| Site work / support | Not quoted | Not quoted |
| Known subtotal only | $5,100 | $4,700 |
A starts with a shell price $700 lower. After the stated delivery and assembly, A's known subtotal is $400 higher. Neither subtotal establishes the complete project cost: site work and any other unconfirmed scope remain unknown.
What must match before comparing these numbers?
- Shell: Confirm the same usable interior, openings and specification.
- Delivery: B explicitly includes delivery in the shell price in this fictional example.
- Assembly: B explicitly includes assembly; neither blank scope nor silence means included.
- Site work / support: Both offers still need the same site-specific written scope.
Send each supplier the same starting brief.
- The job: intended use, equipment list, working or retrieval routes that must remain clear, and the candidate layout.
- The geometry: minimum usable interior and clear opening needed by your tested arrangement. Ask the supplier to identify fixed obstructions and confirm their actual product measurements.
- The site: measured location, access restrictions, chosen arrival method and unresolved ground or drainage questions.
- The scope: ask who supplies each item, who installs it, whether it is included, and what remains unquoted. Keep shell, site work, delivery, openings, services, fees and your own allowances identifiable.
- The record: retain the offer date, version, exclusions and responses alongside your brief. When a specification changes, recheck the layout before relying on its earlier result.
