Assess sites and viability early with a prepared basis for cost planning. RENALDO connects your building data with quantities, work items, prices and durations. Check assumptions, compare options and reuse the project data for planning, procurement and construction – for new builds and renovation.
Start with the work you need and expand when required. Building quantities, services, prices and durations stay connected, from the first decision through construction.
Shared foundation: building data, documents and collaboration connect the modules. Invited participants collaborate for free within their project role; independent professional editing requires the appropriate modules. Collaboration is not an additional module.
AFTER CONSTRUCTION
From the reviewed project to marketing: reuse unit and project data for sales. Sales is a subsequent workspace in the developer workflow, not an additional module in this selection.
RENALDO prepares the starting point. Review, refine and work together. Building data, work items, prices and durations stay connected, for new builds and renovation.
Consider the site, building and viability together. Compare two options with different residential floor areas: building quantities and selected work items form the basis of construction costs. Add your land and revenue assumptions to assess how each option affects the project margin.

An acquisition case that holds
Residual value and maximum land price derived from real trade-level costing – not from gut feeling.
Three-click feasibility
All the way to the residual land value.
Type in an address. Renaldo pulls the standard land value, cadastral map and development potential, works out the maximum massing — and shows GDV, margin and the highest land price the scheme can carry.
Plot, 3D & feasibility – before you buy.
From plot to return in a single pass: official standard land value (BORIS), cadastral map and development potential (plot ratio, site coverage, storeys) with automatic calculation of maximum gross floor area and residential units – no add-on services required. Define the building automatically as maximum massing, manually, or via IFC import – including a walkable 3D model, georeferenced to the parcel. Feasibility is calculated from real trade costs instead of lump sums and shows GDV, margin and residual value – switchable between sale and letting, financing bridge included. Save and compare scenarios.

60 days of the full platform, free – no credit card, nothing charged automatically · per project you only pay once you unlock plans or move into delivery
Do the maths before you sign. Purchase price, development potential and apartment-block costing in one model – you know whether the deal stacks up before you get to the notary.
Real contractor prices, not estimates. Your costs are built on real market prices across every trade – which is why “from day one” actually holds.
One number, from acquisition to exit. Costing, tendering, construction and sale all draw on the same data core – from a single block to a whole portfolio. No spreadsheet breaks.
Built by practitioners: 10 years of retrofit project management plus 30+ years of construction expertise.

Scales per residential unit
Apartment-block structure with buildings, cores and units – quantities and costs scale automatically.
The whole lifecycle
Early stage, construction and sale on one data core – no handover gaps between costing, award and exit.
What you won't find anywhere else.
From acquisition through to operation — all six come out of one configuration. That is why costs, dates and the tender always agree.
The bill of quantities you never have to write
Straight from the configuration into the tender.
Your configuration becomes a tender-ready bill of quantities across every trade — with long descriptions, quantities and unit prices. From there straight into the local search and the online request.
Buildings, cores, units – cleanly structured.
Model apartment blocks and whole neighbourhoods: buildings with cores, storeys and residential units, each with its own room schedule. Quantities and costs are derived from that structure and scale automatically with the number of units.
Building → cores → residential units → room schedule
Quantities scale per residential unit
New build and retrofit in the same model
Site supervision that lets nothing slip through.
A construction schedule with phases and milestones, inspection points derived from the configured works, defects with photo and location – all audit-proof. The digital site diary documents every working day defensibly: weather pulled automatically from the German weather service, entries by dictation, and an AI weekly report at the touch of a button. AI invoice checking reconciles every invoice against the bill of quantities and the awarded contracts.

The project produces brochures per residential unit with AI-written marketing copy, a shareable data room for buyers and lenders, and the listing export – including an automatically pre-filled asking price derived from the feasibility appraisal, the rent roll and the standard land value. The financing bridge supplies the figures the bank and the buyer need – without reassembling anything.

09IFC handover & further designPlan & Calculate
Your designer starts with a model.
A prepared starting point reduces repeated data entry, especially in renovation. RENALDO connects the building model, room schedule and draft drawings. Your designer receives the model via IFC, reviews it and develops the architectural design and subsequent planning.
Start with the existing building
Available LOD2 building data and a hypothetical room schedule provide an initial model. Existing drawings, surveys, scans or IFC data refine that starting point.
Hand over the full model
IFC4 export includes the components present in the model: walls, slabs, roof, stairs, windows and doors, plus spaces, quantities, materials and properties. Draft drawings from the Planning Center support the handover.
Review and develop the design
The designer checks dimensions and existing conditions, adds a measured survey where needed and makes the final architectural adjustments. Professional planning builds on the early design.
LOD2 and a hypothetical room schedule are early design assumptions, not a measured survey. Spaces without a known location remain records without invented geometry. The designer checks import and editability in the chosen CAD system and remains responsible for professional review and approval.
Module: Plan & Calculate. File handover follows the project release rules for plans and data exports; a trial alone does not unlock IFC downloads. Housing and homeowner project and package rules apply.

Acceptance in the order portal
The contractor reads and downloads the contract in the portal and explicitly accepts it. Contract status and the acceptance record stay with the order.
Connect quantities, work items and your next tender.

Keep the agreed baseline
The awarded specification stays with the order as a snapshot. Select new, removed or changed items individually for a variation.
Agree with the contractor
Contractors price requested variations in the portal or submit items and lump sums themselves. When importing a PDF offer, Renaldo flags overlap with awarded work for review as additional quantity or duplicate billing.
Approve and update the schedule
Approval commissions the variation and requires a price. Only approved variations increase the order value. Additional time can be added as a separate schedule task, which also contributes to the progress comparison.

How is Renaldo Developer billed?+
With modules plus a project fee per scheme: Project Complete (€399 net/month, one internal user) or Project Team (€990 net/month, five internal users) include all four project modules, with annual payment available. Per project: the concept is included in the module; unlocking plans starts at €490 (new build) including 5 units; moving into delivery starts at €1,490 including 5 units, then €500 / €350 / €250 per unit (units 6–50 / 51–250 / from 251). Example new build with 50 units: €23,990 net, one-time. Operating buildings you hold is billed optionally through Renaldo Operate (€0.5 per unit per month). You'll get a concrete quote for your own portfolio on the demo call.
Can I try it free first?+
Yes. As soon as you register you have 60 days of the full Developer platform for your entire organisation – no credit card and no sales call. After that nothing is charged automatically: you either book a package, or carry on solo on Developer Start, free for good. The project fee only applies once you unlock plans or move into delivery – nothing is debited quietly.
Can architects, energy consultants and lenders join in?+
Yes. Everyone involved works collaboratively on the same project – with roles and permissions. Participants cost nothing extra; billing runs through the project, not through headcount.
