Analyse your stock, compare renovation strategies and plan investment. For each project, Renaldo calculates and generates plans, costs, bills of quantities and schedules from the building model in a few clicks. Your team reviews the results and manages delivery, including new builds and infill development.
Start with the modules you need and expand when required. Renaldo calculates and generates plans, costs, bills of quantities and schedules from the building model in a few clicks. Review the results and carry them into your work.
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
Keep using project data for technical operations and marketing. Availability follows the respective offer.
Renaldo automatically calculates and generates plans, costs, bills of quantities and schedules from the building model and selected work items. Review, refine and work together, for new builds and renovation.
Explore floors, apartments and rooms in 2D and 3D. A schematic view emerges from the building definition, connected to the room schedule, quantities and costs.
↗
Before an IFC import
Rotate the building, reveal interiors and select floors or apartments. Derived dimensions remain identifiable as assumptions; the schematic view is not a measured floor plan.
↗
Use existing model data
Imported IFC rooms and elements add detail. In the construction schedule, view the sequence on the schematic building or imported geometry.

Build & retrofit serially
The pre-designed apartment-block concepts of the GdW framework agreement on serial construction, matched automatically to your plots – all the way to the supplier enquiry and a pre-configured bill of quantities.
Which properties suit serial retrofitting.
The suitability check scores every existing building against the criteria of serial retrofitting – building type, residential units, construction era – and shows honestly what speaks for or against factory prefabrication, including a cost anchor per m² of living space. Out of your stock grows the longlist for the next retrofit programme.

Every address checked automatically: how much building right is unused, which property suits serial retrofit, which concept fits – as a ranked list of opportunities instead of a hundred individual surveys.
Run in rent
Viability from net rent × multiple instead of sale prices – including the Section 559 modernisation levy with its caps, plus funding. The view a housing company actually decides in.

Address list in, opportunity list out.
Import your stock as text or CSV — every property is enriched with cadastral parcel, planning law and standard land value from official sources and ranked by potential: densification, serial retrofit, concept fit.
The bill of quantities you never have to write
Straight from the configuration into the tender.
The configuration produces a tender-ready bill of quantities across all trades — with full item texts, quantities and unit prices. For serial concepts, pre-configured in system construction.
Good to know

The whole stock – checked automatically for building opportunities.
Paste an address list or upload a CSV – Renaldo enriches every property with official data (cadastral parcel, site-coverage and floor-area ratios, standard land value, existing built volume) and scores three opportunities: densification (unused building right with a unit estimate), serial retrofit and concept fit. As a ranked list and on the map – and any opportunity becomes a project with one click.

Renaldo knows the concepts of the GdW framework agreement on serial construction and checks them against the development potential of your plot – with supplier, construction method, energy standard, CO₂ figure, number of flats and the margin when buying at the standard land value. Adopt a matching concept directly as a project: building structure and bill of quantities are pre-configured in system construction, and you contact the supplier with a ready-to-send letter.

A prepared starting point reduces repeated data entry, especially in renovation. RENALDO generates draft drawings from the building model and room schedule at the click of a button. 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.
09Change orders
Tender & Account
Understand changes. Commission with clarity.
What changed since the contract was awarded? Renaldo connects items, quantities and the contractor’s offer to your decision. Open proposals and approved additional costs remain separate.
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.
Does billing match construction progress? Renaldo connects orders, variations, progress and invoices to highlight overpayment risks before approval.
The decision remains yours. Warnings do not block payment.

Does Renaldo replace our ERP system?+
No – by design. Renaldo is the construction and investment side: analyse the stock, cost measures, tender, build and retrofit serially, run rents and viability. Rent accounting and commercial administration stay in the ERP. Basic technical operations, including rental overview, maintenance planning and simple energy reports, are included within licensed Housing Complete stock.
What is the GdW framework agreement about?+
Renaldo knows the pre-designed apartment-block concepts of the German GdW framework agreement on serial construction and checks them automatically against the development potential of your plots – with supplier, construction method, energy standard, number of flats and the margin at the standard land value. Direct call-off from the framework agreement is open to GdW member companies – anyone can enquire, straight from the app with a ready-to-send letter.
How is Renaldo Housing billed?+
Housing Complete costs €1,490 net per month including 1,000 registered stock units. Additional units are charged marginally: units 1,001–5,000 at €0.80, 5,001–20,000 at €0.50, 20,001–50,000 at €0.30, and above 50,000 at €0.15 per month. Twelve-month minimum term, monthly invoices on the first, based on registered stock at midnight Europe/Berlin. Additions and removals take effect the following month. Renovation projects in licensed stock are included; new-build projects carry a one-off project fee without a second Developer base fee. A completed new unit enters stock billing after handover, whether rented or vacant. Existing contracts are preserved. Full pricing and terms
