Your first bike-build tool budget: own, borrow or pay for the job
The parts basket looks affordable. Then the tool basket arrives. For a first build, buying every workshop tool can consume the money you meant to save. Divide the work before buying the tools.

Own the tools for recurring tasks
List jobs you expect to repeat: tyre pressure and punctures, cleaning, chain checks and supported adjustments. Choose tools for the actual parts and instructions. Park Tool’s tool-planning guide is useful for separating jobs from equipment; it is not a requirement to buy its entire range.
Borrow safely or quote specialist work
For a GRARO build, bottom-bracket installation, hose cutting/bleeding and steerer work depend on the exact configuration. Borrowing only helps when the tool is correct, sound and you know its procedure. If not, ask the workshop to quote those jobs and final checks. A press or torque tool whose suitability or condition you cannot establish is not a sensible budget saving.
Use the torque-tool range check before adding that tool to the list, and scope steerer cutting separately with the workshop.

Compare the complete cash requirement
Add missing tools, consumables, required parts and any paid finishing work to the DIY path. Compare with the workshop’s scoped quote, including what parts you supply. In an illustrative comparison, €180 of tools plus €70 finishing work is €250—not a “free” home build. These are example figures, not local prices.
Use the same parts and completion scope on both sides. If the workshop quote covers labour only, keep parts separate in both totals; if it includes consumables and a final check, add their DIY equivalents too. The €250 example is assembly spending, not a whole-bike price.
If you enjoy learning and will reuse the tools, that value belongs in the decision. If the aim is one reliable bike with minimum hassle, a mixed plan often makes sense: routine care at home, specialist assembly at the shop. Keep the task list so neither side assumes the other completed the final safety checks.
