What software do property developers use to track multiple sites?

Many teams track sites across spreadsheets, shared drives and email. Atlasly Developments gives each site one record instead: its stage and owner, parcels, due diligence documents with page citations, development options, appraisal, actions and project packs, with a portfolio view of what needs attention and what is due across every site.

Does it calculate residual land value, IRR or a cash flow?

No. The Developments appraisal works out profit, profit on cost and profit on GDV from the land price and costs you enter, with sensitivity to sales, build cost, land price and programme. It has no dated cash flow, IRR or residual land value solve. For a quick land-side screen, use the free residual land value calculator, and keep a full cash-flow model with your advisers.

Can I track UK title numbers and US APNs in one portfolio?

Yes. Each parcel keeps its own reference (title number, folio, APN or UPRN) and boundary status, and each project records its currency (GBP or USD) and units (metric or imperial), so UK, Irish and US sites sit in the same portfolio.

Can it produce a pack for an investment committee or lender?

Yes. A project pack fixes the current record with the exact document versions, option revisions and appraisal versions it used, and states gaps rather than hiding them. Print it or save it as a PDF, or download it as Markdown.

Does it replace Northspyre, Procore or ARGUS Developer?

No. Budget, draw and construction management tools such as Northspyre and Procore, and cash-flow appraisal tools such as ARGUS Developer, do different jobs. Developments is the pre-construction record of a site — evidence, options, a profit-based appraisal, decisions and packs — and can sit alongside them.

Who is Atlasly Developments for?

Property developers and development teams who manage several sites at once: acquisitions, development managers and land and planning leads. Architects, planning consultants and cost consultants can be invited to a project as viewers or editors.

How is it different from Atlas AI?

Atlas AI answers questions about a site: constraints, planning context, policy and feasibility. Developments is where you manage a project over time: its parcels, documents, options, appraisal, actions, team and packs. They share the same projects, so an Atlas AI project can be added to Developments without starting again.

Can it connect to Google Drive, Gmail, Microsoft 365 or Outlook?

Not yet. Those connections are built but are not available until Atlasly completes each provider’s registration. Today you can upload PDFs and import email files (.eml) exported from any mail app.

Does the appraisal give a valuation?

No. It is a deterministic development appraisal: every output follows from the figures you enter by fixed formulas, each figure is tagged as supplied, an estimate or an assumption, and missing inputs stay unknown rather than being filled in. It is not a valuation and says nothing about planning approval.

How do colleagues get access?

An owner or admin adds a colleague by the email they sign in with, as a viewer, editor or admin. The colleague needs to have signed in to Atlasly once. Atlasly does not send invitation emails; you share the project link yourself.

Can it read scanned documents?

Only PDFs with a text layer are read. Pages without readable text are flagged as needing review rather than guessed, and cannot support findings or answers until checked.

Who it is for

Built for development teams that carry sites from appraisal to delivery.

Developers and development managers

See the whole portfolio, what is overdue and what changed since you last looked, then open any project exactly where you left off.

Acquisitions and land teams

Record parcels with their title numbers or APNs, run site due diligence, compare options and test the numbers before an offer or investment committee.

Consultants and colleagues

Architects, planning and cost consultants join a project as viewers or editors and work from the same versions.

The problems it solves

Why development teams lose track of a site.

Evidence is scattered

Surveys in one drive, the pre-application reply in someone’s inbox, the vendor’s terms in another. Developments keeps each document and email with its version, sender and date, against the project and parcel it concerns.

Nobody is sure which version is current

Replacing a document keeps the earlier version readable. Options keep every revision. Packs record the exact versions they used and never change afterwards.

The numbers drift from the scheme

An appraisal prices one exact option revision. When the selected revision changes, the project says the appraisal is out of date instead of quietly mixing figures.

Assumptions look like facts

Findings are kept apart as facts cited to a page, assumptions, calculations and open questions. Appraisal inputs carry a source tag. Missing information is shown as not known.

How it fits together

Track every development site in one record.

Each project opens on what to do next and how complete its record is: established, in progress, needing attention or not started.

01 · Site
Parcels with title numbers, folios and APNs
Record each parcel with its title number, folio or APN and draw or import its outline. A boundary stays unconfirmed until someone checks it against a source.
How it works
02 · Evidence
Due diligence documents with page citations
Upload PDFs and email files. Each document shows whether it could be read, keeps its versions and can be cited by page. Record facts, assumptions and open questions as you go.
How it works
03 · Options
Development options compared side by side
Compare alternatives on the same figures — homes, footprint, floorspace, storeys, coverage — with the assumption behind each. Bring in saved Canvas options with their exact version.
How it works
04 · Appraisal
Development appraisal: profit on cost and on GDV
Test land, build, finance and sales figures for the selected revision. Profit, profit on cost, profit on GDV, the cost breakdown and sensitivity stay in view.
How it works
05 · Work
Actions, milestones and reviews
Owned, dated actions that can wait on each other, milestones for the project stage, and reviews of the exact versions your team relies on.
How it works
06 · Pack
Project packs for committees and lenders
Generate a readable pack of the current record with the versions it used. Print it or save it as a PDF for a committee, lender or consultant.
How it works

Development project overview with the suggested next step, project record and what needs attention — Project overview: the suggested next step, the project record and what changed since your last visit.

Site due diligence documents listed with readable status, version and parcel — Evidence: readable status, versions and parcel attribution for each document.

Development options compared by homes, floorspace, storeys and site coverage — Options: compared on the same figures, with the selected revision marked.

Development appraisal with profit on cost, source-tagged inputs, cost breakdown and sensitivity — Appraisal: every input tagged supplied, estimate or assumption; missing inputs stay unknown.

Your first project

Start with what you already have.

A site

Name the project, add the address and parcel references, then draw the boundary.

Documents

Upload the survey, reports and correspondence you hold. Unreadable pages are flagged, not guessed.

An Atlas AI project

Add an existing project. Its documents, findings and appraisals come with it.

Within the first session you can have the site recorded, the evidence organised with what is missing made explicit, the next actions assigned and a first pack ready to share.

Developments or Atlas AI?

Ask Atlas AI about a site. Run the project in Developments.

They share the same projects and evidence. Start in Atlas AI when you want answers about a place; add the project to Developments when it becomes something you are taking forward.

Scope

What Developments does not do.

Not a valuation

Appraisal outputs follow from your inputs by fixed formulas. They are not a Red Book or other formal valuation and say nothing about planning approval.

Not a cash-flow model

No dated cash flow, IRR or residual land value solve. Screen land value with the free residual land value calculator and keep your full model with your advisers.

Not construction management

No construction budgets, draws, invoices or cost control. Developments covers the site before and around the decision to build.

Screening land value? Try the residual land value calculator. Preparing to exchange? Work through the site due diligence checklist for developers.
