Set a decision point before each major cost
Begin with a defined commercial objective and a boundary plan. Identify what must be known before purchase, before detailed design and before submission. A staged scope should resolve the most consequential uncertainty first. For example, an unresolved access or use restriction deserves attention before an expensive interior specification.
Record assumptions in the appraisal. If a proposed number of units depends on an unmeasured roof space, third-party access or an unconfirmed drainage connection, show how the project changes if that assumption fails. A lower capacity supported by evidence can be more useful than an optimistic figure that cannot survive technical design.
Develop capacity from a workable layout
Test the site against its Leeds policy context and the physical relationships. Show neighbours, levels, trees, entrances and servicing. For housing, consider usable space, light, privacy and accessibility from the start. The best unit count is the one that supports a coherent planning and building solution, not necessarily the largest number that fits on a diagram.
Keep a short option record explaining why alternatives were rejected. It helps the project team resist repeated redesign when a later cost estimate creates pressure to add units. If a higher-capacity option has a specific unresolved risk, price and programme that investigation instead of treating the option as certain.
Budget for obligations and technical evidence
Check the Community Infrastructure Levy position and any relevant relief requirements before commencement. Leeds warns that qualifying for an exemption is not enough without completing the required process. Consider any Section 106 obligations associated with the land or proposed permission; these can continue to affect a purchaser.
Prepare a proportionate survey schedule covering the issues actually identified. Ecology, drainage, heritage, highways or ground-condition work should be commissioned with a clear question and current drawings. Use one coordinated layout so technical advisers are assessing the same proposal and their recommendations can be reconciled before submission.
Plan beyond the decision notice
Allow for conditions, any legal agreement, technical approvals and procurement after permission. Establish who will discharge conditions and maintain the record of approved information. If a contractor proposes a change to save cost, review the planning implications before implementing it. A permission is most useful when the team understands how to deliver the approved scheme.
For a Plandome enquiry, provide the address, ownership or purchase status, intended development, available plans and key commercial deadline. The first recommendation should set out the approval route, principal risks and next evidence required. Avoid programmes based solely on a statutory application period; the preparation and post-permission work can materially affect when construction is ready to begin.
Your questions, answered
Should I request pre-application advice on every site?
It is useful where a focused policy or design question needs an officer view. First establish the facts and the decision it will inform; a clear feasibility review can determine whether the enquiry adds value.
Are small schemes free from infrastructure and ecology requirements?
Not automatically. Applicability depends on the proposal, site and relevant rules. Check contributions, exemptions and environmental requirements specifically rather than relying on the label small development.
