The refusal arrived. The decision matters more than it looks.

Around 440 small-site applications are refused across London each year. The decisions cluster in unhelpful places: design, amenity, transport, the borough’s particular reading of policy. Before you commit to an appeal, a redesign, or selling the site on, it helps to know how the same borough has treated comparable schemes recently.

A Site Assessment, applied to a refused scheme, costs £1,250 and takes 48 hours.

Three real refusal reasons, on schemes like yours

Verbatim text pulled from London Decision Notices in the dataset. These are not the most extreme cases. They are the most common.

By reason of its layout, scale, massing and design, the proposal represents an overdevelopment of the site which would result in a cramped form of development that would be out of keeping with the character of the area. Croydon, design / character · 50% of pan-London refusals cite this category
The proposed development would constitute an unneighbourly form of development that would harm the amenity of [neighbour] in the form of being overbearing, creating an increased sense of enclosure and loss of sunlight. Croydon, amenity · 33% of amenity reasons cite enclosure
The proposed parking, cycle and refuse area would have a poor quality layout and it has not been demonstrated that the rear of the application site can accommodate the required refuse, cycle and parking provision. Croydon, transport · highway access cited in 44% of transport refusals

The phrasing repeats. Whatever your borough refused you on is, in the strict sense, the borough’s view of how the site looks against three years of comparable decisions. Most of that view is visible in advance if you know where to look.

Three options the data has views on

Option 1 · Appeal

Is the borough wrong, or is the scheme wrong?

Appeals against design refusals run at materially lower success rates than appeals against process or policy errors. We can show you the borough’s appeal-success rate for your refusal category, and the precedents that came back positive.

Option 2 · Resubmit

What changes pass, what changes don’t?

Most resubmitted schemes are refused again on the same grounds. The schemes that do get through tend to make two or three specific changes. We can show you what those changes look like in your borough, drawn from the comparables that succeeded.

Option 3 · Walk away

Is the site the problem?

Some sites are systematically harder. Backland infill in conservation areas. Density above the local approved median. Sites the borough has already refused twice on similar grounds. Sometimes the right move is to sell to someone whose model fits the borough.

What a Site Assessment shows for a refused scheme

You send the address, the application reference, and the refusal reasons. Within 48 hours you receive an HTML and PDF Site Assessment containing:

  • A risk-rated read on each of your refusal reasons against the borough’s pattern
  • Comparable approvals in the borough on similar sites: addresses, schemes, what they did differently
  • Resubmission probability at the current unit count and at lower counts
  • Appeal-precedent data for the specific refusal category in this borough
  • A capacity model: the unit count and density the borough has actually approved on sites like yours
  • A free 30-minute follow-up call with the analyst (Abre Etteh, ARB-chartered, author of the LB Merton Small Sites SPD) to walk through the report

The Site Assessment is not a recommendation on what to do. It is the data underneath the decision.
