The whole building project – from the plot to operation.
Three core phases that run the same way on every project – plus early stage, sale and operation for developers and portfolio holders. For new build and retrofit, from single-family homes to apartment blocks.
Free to start · 30/60 days of full features.
Early stage & acquisition
Plot, development potential and feasibility – before you buy.
Plan & cost
Capture the existing building, cost it with real contractor prices, and secure funding.
Tender & award
Find the right firms, put the works out to tender, and compare bids safely with AI.
Build & settle
Construction, quality and invoices under control – safely to the final invoice.
Sale & exit
Brochure, data room and listing – out of the same project data.
Operation
Tenants, maintenance, running costs and ESG on the same asset data.
What you won't find anywhere else.
All six come out of one configuration. That is why costs, dates and the tender always agree — and why Renaldo can also see what is missing.
Three-click feasibility
All the way to the residual land value.
Costing without a quantity take-off
Quantities from the building, prices from the market.
The bill of quantities you never have to write
Straight from the configuration into the tender.
The bid comparison that shows the gaps too
Every bid measured against your own bill of quantities.
The construction schedule that writes itself
And everyone involved keeps it current.
From ESG baseline to a costed retrofit
Rating, measure, new class.
Early stage & acquisition: plot, potential and return – before you buy.
From plot to return in a single pass: official standard land value (BORIS), cadastral map and development potential, with automatic calculation of maximum gross floor area and residential units. Feasibility is calculated from real trade costs rather than lump sums – and shows the residual value, i.e. the maximum land price the scheme can carry.
Plot & planning law
Official data for the address, no add-on services.
- Standard land value (BORIS) & cadastral map
- Development potential (site coverage / plot ratio)
- Max. gross floor area and residential units
3D building model
Automatically as maximum massing, manually, or via IFC import.
- Walkable, georeferenced to the parcel
- Sun path & overshadowing
- Official LoD2 data
Feasibility
Real costs instead of lump sums – for sale or for rent.
- GDV, margin & residual value
- Financing bridge (loan, DSCR)
- Save & compare scenarios
From first idea to a number that holds – with real contractor prices.
Configure the works – a plan, not a puzzle.
From trade down to individual line item – works on five levels, drawn from 20 trades plus design and project support. Automatically linked to the building data. With suggestions, alternatives shown explicitly and dependencies checked automatically – meaning clear packages for clients and less back-and-forth for professionals. When a project involves many trades or a large volume, Renaldo automatically suggests matching design and support services in the basket.
- Five levels down to a tender-ready line item
- 20 trades plus design and support, at real contractor prices
- Automatic design recommendations in the basket
From existing building data to a cost estimate – no detours.
Adjust the works configuration in a few steps and turn existing data into reliable cost estimates fast: from an individual retrofit roadmap (iSFP), via the retrofit calculator with measures proposed from the existing building, through AI damage analysis, or by importing reports and free text (particularly useful for building professionals).
- Interior-fit-out wizard: simple yes/no questions pick the trades
- Retrofit calculator with proposed measures
- iSFP, AI damage analysis & text/report import
GEG check, funding & measures – in one place.
The “Energy advice” page brings together everything you need to know about your retrofit, matched to your building data: a GEG check against German building-energy law (U-values, efficiency-house levels), a funding check covering BAFA, KfW, federal-state and municipal schemes, and a recommendation of measures. Renaldo checks which programmes apply and keeps an eye on the deadlines for you.
- GEG check per building element (U-values, efficiency-house levels)
- Funding check: BAFA, KfW, federal states & municipalities, with amounts
- Measures recommended in a sensible order, deadlines in view
Find the right firms, compare bids with confidence.
Approach firms in your region in three clicks.
Compare contractors by rating, capacity and price level – and request bids that match your works exactly, in one click.
Gaps and pricing risks, visible immediately.
Analyse bids one by one or side by side – Renaldo shows missing items, unusual prices, risky clauses and differing specifications at a glance.
Turn your design work into a binding fee proposal – awarded online.
Professionals produce a complete proposal per project, contract terms included – built from Renaldo service modules or on the German HOAI fee scale, with prices pre-filled and a payment schedule. Via the basket, those costs land straight in the client's budget. The client sees the proposal through an email link without logging in, and awards the work online.
- Two costing methods: service modules or HOAI fee scale
- Costs land in the client's budget directly (basket link)
- Appendices & contract wording including right-of-withdrawal notice, automatically
- Sent by email link – the client awards online, no login
Safely through construction – right to the final invoice.
Record defects with a photo and a location.
Document defects with a photo and a location – structured, from site visit through to handover. Nothing gets lost in a chat thread: every item has a status, an image and a trade.
Upload invoices – see the discrepancies in minutes.
Upload the invoices and the AI reconciles them automatically against your awarded contracts.
- Reconciled against works & quantities
- Suspicious line items flagged
- Traceable for the whole team
Phases, tasks, milestones – in one place.
Keep the phases, tasks and milestones of your project under control at all times. Tasks are a two-level checklist, and every phase has its own detail page with thematic icons and an integrated drawing register.
Sale & exit: from finished asset to sale – out of the same data.
The project produces brochures per residential unit, a shareable data room for buyers and lenders, and the listing export – including an asking price pre-filled automatically from the feasibility appraisal, the rent roll and the standard land value. Nothing has to be assembled again from scratch.

- Vacancy & contracted annual rent
- Average € per m²
