The problem

Every opportunity sits across five different desks.

You need a planning consultant to tell you what's permissible. A quantity surveyor for build costs. A valuation surveyor for exit value. A credit analyst for refinancing potential. And a developer who's done this before to tie it all together.

Most deals fail not because the opportunity isn't real — but because no one has the full picture in one place.

Secondary city property is misunderstood by London-centric investors. Underutilised retail is dismissed as dead. Former banks are torn down when they should be converted. Obsolete offices sit vacant while housing demand is acute.

The pricing gap exists precisely because the analysis hasn't been done.

How it works

The analysis engine.

01

Asset identification

Former banks, vacant offices, underutilised retail, light industrial, mixed-use high street. SiteDeck scans for properties where market pricing undervalues redevelopment potential.

02

Planning pathway analysis

Permitted development eligibility. Local authority policy. Nearby approved applications. NPPF compliance. Demographic trends. Transport investment signals. All synthesised into a planning probability score.

03

Financial underwriting

Build and professional costs. Optimal unit mix or use case. Stabilised rental income. Refinance valuation. Downside and upside scenarios. Project-level IRR. Debt and refinancing assumptions.

04

Execution intelligence

Execution risks flagged. Alternative development strategies compared. Highest and best use determined. Acquisition attractiveness scored. Deal memo generated — ready to take to a lender or joint venture partner.

Asset types

What we're looking at.

Former Banks

High street footprint, solid structure, planning histories. Prime for conversion to apartments, serviced accommodation, or mixed-use.

Vacant Offices

Out-of-cycle buildings in towns undergoing structural change. HMO, co-living, standard residential — depending on location and demand.

Underutilised Retail

Empty high street units, tired shopping parades, retail warehouses. Where other investors see decline, SiteDeck sees densification potential.

Light Industrial

Low-rise commercial units in transitional zones. Often PD-eligible. High residual site value once freed from industrial use.

Mixed-Use High Street

Fragmented ownership, inconsistent tenants, obsolescent layouts. Sites where assembled ownership unlocks material value.

Obsolescent Estate

Inefficient commercial buildings in areas of structural demand change. Often priced for continuing decline. SiteDeck prices for the recovery.
