Replace fragile spreadsheets with defensible investment decisions

Alasco Development Appraisal replaces fragile spreadsheets with a structured yet flexible calculation tool – so you can compare opportunities instantly, analyse scenarios in minutes, and transfer your approved appraisal into project execution as the budget baseline.

Trusted by Europe's leading real estate developers

Appraise deals with confidence

Every deal gets to your desk as a teaser. A few numbers, a tight timeline, and a committee that wants three scenarios by Friday.

Today, that means hours in Excel: copying tabs, rebuilding cashflows, fixing broken links, and hoping the one person who understands the model is available.

Alasco gives your acquisition team a structured, flexible calculation environment that works the way they do. Build your first screen in minutes. Create and compare scenarios in one click. Model financing dynamically. And when you win the deal, transfer the approved appraisal directly into execution – no re-keying, no media break, no lost assumptions.

CHALLENGES

Excel isn't built for development appraisals

Formulas break – and no one catches it in time

Broken links, accidental overwrites, and formula errors are the single most common pain we hear.

No centralised benchmark data

Cost benchmarks, rent comparables, and yield factors live across old files, email threads, and people's heads. There's no structured way to access them or trust them consistently across your team.

No standardisation across projects or offices

Even within one company, different offices use different structures. Cross-project comparison becomes a manual exercise in harmonisation.

Scenario comparison is slow and error-prone

Comparing scenarios means copying tabs, rebuilding summary sheets, and hoping nothing breaks. A structured side-by-side view doesn't exist in Excel. Some teams end up running over 100 scenario variants on a single deal.

Planning and execution live in separate worlds

When a deal closes the link between your planning assumptions and actual outcomes disappears the moment the file is handed over.

Knowledge lives in one person's head

The model is understood by one or two people. When they leave or are simply unavailable, the organisation loses the ability to maintain – or even read – it.

How Alasco solves your need to appraise with confidence and speed

Scenario comparison – in one click

Create multiple calculation variants and compare them side by side instantly. Whether you're presenting three scenarios to a committee or modelling 20 variants during, Alasco handles it without a single copied tab.

  • Automatic diff-analysis across scenarios – see exactly where they diverge.

  • Hierarchical version tree showing which variants you've explored and which you've shelved.

  • Frozen versions for board approval, with full change history: who changed what and when.

Excel flexibility without the fragility

Bring your own templates, formulas, and cost group structures. Alasco keeps the calculation logic you've built over years – in a stable, standardised environment that prevents accidental overwrites and protects shared model integrity.

  • Custom template uploads with AI-assisted import of your existing Excel models.

  • Consistent structure across every project, team, and office.

  • Protected model logic that keeps formulas intact regardless of who’s working in the file.

Dynamic cash flow and financing

Equity timing, loan tranches, interest accrual: model them dynamically and watch IRR, liquidity peaks, and interest costs update in real time as your timeline changes.

  • Time-phased cash flows by month or quarter.

  • Residual land value calculation.

  • Sensitivity analysis on GDV and build costs.

  • Liquidity views tying costs, financing phases, and revenue.

Three things that set Alasco apart

The appraisal-to-execution loop

No other tool connects the feasibility phase to project execution. Alasco already owns the execution side. Connecting your appraisal creates a closed data loop: your planning assumptions become your execution baseline, and your actuals become your next set of benchmarks.

Data-driven benchmarking that gets better over time

Alasco aggregates anonymised data from 5,000+ projects across the platform. Use Alasco Benchmarks alongside your own internal historicals to pressure-test assumptions and catch outliers before they become problems. The more projects you deliver, the smarter your future estimates get.

Organisational standardisation with controlled flexibility

Centralised templates mean every team works from the same methodology. Controlled flexibility means they can still adapt to the deal in front of them. Knowledge stops living in individual files and starts living in the organisation.

FAQ

Frequently Asked Questions

Can I import my existing Excel models?

Yes. Alasco supports direct import of your existing Excel development calculations. An AI-assisted mapping tool reads your cost group structure and transfers it into Alasco's framework – so you don't rebuild from scratch.

We run dozens of scenarios per deal. Can Alasco handle that?

Yes, and that's exactly what it's built for. Alasco supports unlimited scenario variants, organised in a hierarchical version tree so you can see which variants descended from which parents, which ones you've shelved, and which ones you're still developing. Side-by-side comparison and automatic diff analysis show you where scenarios diverge.

How does the connection between appraisal and execution actually work?

When a deal is approved, you transfer the appraisal directly into Alasco Financial Management as the project budget baseline. From that point, all cost commitments, invoices, contracts, and financing data in execution are measured against the original planning assumptions.

We already use Alasco for cost controlling. Do we need a separate setup?

No. Development Appraisal is an integrated module within Alasco. Connecting appraisal is an extension of the platform you already know.

Can different offices or teams use different calculation templates?

Yes. You can maintain multiple templates – by asset type, by region, by entity – while keeping them under the same organisational governance.

What happens when the person who built our Excel model leaves?

That's precisely the risk Alasco eliminates. Because the model logic lives in the platform – not in a file on someone's desktop – new team members work from the same template from day one. The methodology belongs to the organisation.

Do banks and investment committees accept Alasco output?

Banks increasingly require defensible, auditable calculations before approving financing. Alasco produces version-controlled scenarios with complete change histories, frozen approval snapshots, and full traceability of assumptions. You can demonstrate exactly which version your committee approved and what has changed since.

Is my data secure and kept separate from other customers?

Yes. All customer data is held in logically isolated environments. Alasco Benchmarks are built from anonymised, aggregated data and never expose customer-specific project information to third parties.

What does Early Access pricing look like?

Pricing depends on team size, number of active projects, and which Alasco modules you use. Book a demo and we'll walk you through the options relevant to your pipeline.
