How It Works

Structured Residential Feasibility Intelligence

Property Stalker converts fragmented public datasets into structured, scenario-based residential development intelligence — integrating authoritative property data and applying a disciplined modelling framework to quantify development-driven uplift.

Structured feasibility intelligence
The Pipeline

Six structured steps, address to report

1
Step 1

Property Identification

Search by address or postcode. The system retrieves and integrates authoritative sources into one verified baseline before modelling begins.

HM Land Registry transaction history
EPC floor area & property characteristics
Local planning activity
Market growth indicators
Geospatial context

A verified baseline — established before a single assumption is made.

Step 2

Scenario Selection

Choose development scenarios. Each is governed by structured compatibility logic, so only realistic assumptions enter the model.

Rear single-storey extension
Double-storey extension
Loft conversion
Garage conversion
Internal reconfiguration

Structured compatibility logic keeps every scenario grounded in reality.

Step 3

Area & Build Cost Modelling

The system structures costs through a scenario × cost-category matrix for applicability accuracy — producing a total investment projection.

Scenario-based area calculations
Build cost schedules
Professional fees
Contingency assumptions

A scenario × cost-category matrix → one total investment projection.

Step 4

GDV Calculation

Property Stalker calculates Gross Development Value across multiple inputs, returning Cautious, Base and Optimistic projections.

Three confidence bands — Cautious, Base, Optimistic.

Step 5

Uplift & ROI Analysis

The crucial step: the system separates general market appreciation from development-driven value-add — providing structured risk signalling.

Why This Matters

Modelling discipline, at the earliest stage that counts.

Most property decisions rely on fragmented data and subjective interpretation. Property Stalker introduces structured modelling discipline at the earliest stage of acquisition and valuation.

Reduces informational friction

One integrated baseline replaces hours of manual cross-referencing across siloed portals.

Improves capital allocation

Objective uplift and ROI signals direct capital toward genuine development value — not market noise.
