Development intelligence, grounded in your data
Turn a site into a development decision.
Appraise development feasibility with your own real-world cost history. Sitewise connects scheme, cost, value and land in one guided workflow.
Don’t have everything yet? No problem. Add information later.
Built on clear principles
Intelligence you can interrogate, not a black box.
Private by company
Your development history stays inside your company’s secure dataset.
Sources stay visible
Historical costs and AI assumptions are always clearly distinguished.
Calculations stay deterministic
Appraisal mathematics runs through transparent application logic—not a language model.
Every assumption is editable
Review the inputs, test the sensitivity and keep control of the decision.
One connected appraisal
From red line to residual land value.
A guided workflow gives land and development teams the answer without recreating a spreadsheet for every opportunity.
Make your past projects useful on the next site.
Upload cost plans, actual costs, final accounts, programmes and appraisals. Sitewise extracts useful intelligence without exposing complicated data structures.
