Extend Planning Permission Scotland – Small Site Case Study (Perth & Kinross)

Local / Small Site Case Study: Planning Consent Protected and Optimised

Town Centre, Perth & Kinross

Planning Consent Protection and Renewal for Permissions at Risk of Expiry

Context: Town centre redevelopment, Perth & Kinross

Development Type: Five flatted residential units and ground-floor commercial use

Planning Route: R.E.N.E.W Protocol applied early via targeted condition variation

The Planning Risk

Town centre mixed-use permissions often carry layered conditional controls, particularly where residential and commercial elements are combined and implementation depends on thorough due diligence and construction management planning.

Once permission is granted, the clock starts immediately. In this case a three-year time period applied to the consent. However the consent was exposed to risk due to:

  • Conditional wording limited flexibility in how and when different elements of the scheme could be brought forward.
  • The need to discharge conditions and secure other statutory consents before meaningful and lawful start could be made on site.
  • Short timescales to market, purchaser due diligence, funding, and delivery

Without early intervention, the permission risked becoming difficult to implement within its lifespan, increasing exposure to expiry and loss of value.

What Was at Stake

If the consent had been allowed to run down without strategic review, the fallback option would have been a full reapplication.

That route would likely have involved:

  • New planning application fees and statutory advert costs
  • New consultancy and survey inputs to re-prepare and support a fresh submission
  • Assessment against new policies.
  • A review of against developer contribution requirements.

This would have reset the project back to square one, introducing fresh policy risk and additional delay — all for a development that was already accepted and granted.

By contrast, the R.E.N.E.W intervention was delivered in a way that protected and optimised the consent thus avoiding the need for wholesale rework.

The R.E.N.E.W Intervention Applied

Review — Understanding the real constraint

A detailed audit of the permission identified that development-wide condition wording created unnecessary risk. Certain requirements were drafted in a way that could prevent parts of the scheme from being implemented independently.

Evidence — Selecting the correct legal route

Rather than reopening the principle of development, our strategy deployed a mechanism that optimised the scheme deliverability as well as extending the lifespan of the consent. This route:

  • Focuses solely on the acceptability of conditions
  • Avoided re-consultation on the principle of the scheme
  • Minimises the need for multiple consultant and survey rehire

Navigate — Policy-aligned, proportionate adjustment

The approach remained tightly aligned with the statutory development plan (NPF4 and the adopted LDP), ensuring that amended conditions:

  • Met the six tests for planning conditions
  • Remained enforceable and precise
  • Were proportionate to the impacts they were intended to manage

Extend — Protecting implementation flexibility

Targeted revisions were proposed so that:

  • Residential units could be brought into use independently of the commercial element
  • Amenity safeguards remained fully in place where relevant
  • The consent could be implemented in phases, reflecting commercial reality

Win — A safer, more usable permission

The outcome was a planning permission that remained live, flexible, and defensible, reducing risk during marketing, funding, and delivery.

The Outcome

What was achieved

  • Planning consent protected from expiry risk
  • Implementation flexibility restored through proportionate rewording of conditional control
  • Momentum preserved while other statutory consents were secured
  • Minimal consultant rehire and no requirement for fresh surveys

What was avoided

  • A full reapplication and associated policy exposure
  • Loss of time during a critical marketing and due-diligence window
  • Avoidable reapplication and professional costs – Approximately £5,500 saved.

Why This Matters for Other Small Sites

For small and medium sites, planning risk rarely sits in the principle of development. It sits in:

  • Timescales
  • Conditions
  • The gap between permission being granted and a scheme being ready to move forward

Once consent is issued, active management is essential. Waiting until the expiry date approaches often removes the safest options.

Planning Consent at Risk?

If your small site has been granted planning permission but constrained by time, conditions, or delivery sequencing, the R.E.N.E.W Protocol provides a structured way to protect it.
