PLAIN-ENGLISH PROJECT GUIDES
Should we proceed, redesign or walk away?
Compare realistic options against your priorities and limits, rather than forcing the original design to work.

Set the tests before choosing an option
Write down the essential outcome, spending limit, acceptable disruption and deadline. Then compare options using the same assumptions. Changing the rules to favour a preferred design makes the comparison less useful.
Show the trade-offs
A smaller extension may preserve the essential living space but lose a guest room. Phasing may ease immediate funding pressure while introducing repeat site setup and future disruption. Refurbishment may retain useful fabric but expose condition risks. There is rarely a cost-free compromise.
Find out which uncertainty matters most
If the choice depends on structural condition, commission appropriate investigation before further design. If it depends on planning, obtain relevant advice. Spend the next pound on information that could change the decision, not simply on making the preferred option look more finished.
Record a clear decision
Proceed with agreed conditions, redesign a specific element, pause pending evidence or stop. Explain why, what remains unresolved and who owns the next action. Walking away can be a sensible outcome; it is not automatically a failure or a guaranteed financial saving.
Your practical checklist
- Agree your decision criteria.
- Compare a baseline and genuine alternatives.
- Investigate the uncertainty that could change the decision.
- Record the choice and conditions.
