Four steps to a cost estimate
The Renaldo app gives you a regionally calibrated cost estimate with a funding note and a plausible price range – initially without an account. You only create a profile, optionally, when you save. Renaldo suggests the modules that fit – you just confirm.
1. Enter the address
Enter the address of your property. We load the data and the regional price factors.
2. Pick trades with the wizard
The interior fit-out wizard asks simple yes/no questions (bathrooms, floors, walls …) and selects the right trades automatically.
3. Check the building data
Review the building data we found and adjust it where needed.
4. Cost estimate + AI analysis
You get your cost estimate immediately – plus an AI-supported energy analysis with measures, costs and funding.
In the app you turn that rough estimate step by step into a reliable cost plan — the cost-certainty indicator shows what is still missing (confirm the building data, complete the works modules).

Looking for someone to guide you? Certified Renaldo retrofit coaches are listed in the app's coach search, with the distance to your address; certified coaches are shown first. (The coach programme is currently German-language.)
Building new? Renaldo costs that too.
Not just retrofits: plan your new build with cost truth as well. Cost the trades at real contractor prices, check the new-build funding available (such as the German climate-friendly new build scheme) and manage bids in the same cockpit – from the first estimate to handover.
- New-build costing at real contractor prices

Renovating today usually means spreadsheets, paperwork and sleepless nights.
“You don't want to sign blind – but you can't check the quote technically either.”
“Dates, decisions, photos – all scattered across emails, messages and folders.”
“Funding is complicated – the wrong signature can cost you €10,000 in no time.”
“After six months of building work the stress should be over – not worse.”
That is exactly what Renaldo Home Projekt is for.
Seven tools that make your project safe.
Seven tools across three phases — plan & cost, tender & award, build & settle. The same three phases guide you inside the app: the task view always shows what's next.
1
Tender & award
Find local professionals, check bids with AI, visualise your home with AI and choose materials at live prices.
3
Build & settle
Have invoices checked automatically and get answers from SAM whenever you need them – safe right to the end.
1
Upload a contractor's quote – checked against BEG immediately.
Upload a PDF quote: the AI checks U-values, COP, minimum technical requirements and other criteria of the German BEG funding scheme, and shows whether you could be losing out on grants.
- Stops you awarding work that turns out not to be eligible
- Ideal before you award – not once you're filing the application
Approach local professionals in three clicks.
Compare contractors by rating, capacity and price level – and request bids that match your works exactly, in one click. Contractor quote requests require Home Projekt from the first request. Cost estimates, SAM and iSFP import remain free in Start.
Via “add a retrofit coach” in your team you'll find certified retrofit coaches – shown at the very top (ahead of distance), with a distance label to your address and a “certified only” filter.
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.
Choose materials – with a price and a showroom round the corner.
Pick floors, bathroom fittings, tiles and the rest from curated products at live prices – as a genuine checklist that walks you through the selection step by step. The showroom search is variant-specific – “textured-render display” rather than just “façade”.
- A real checklist with progress
- Variant-specific showroom search
- Live prices, pulled straight into the project

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 everyone involved
Quick configuration & wizard
Interior fit-out wizard (yes/no questions), retrofit calculator and AI damage analysis – a realistic order of magnitude early on, instead of guesswork.
Task list
Who does what by when – with due dates, status and reminders for you and everyone involved.
Professional PDF export
One document for the bank, the trades and your partners – generated in seconds.
Financing PDF
Produce your financing PDF for the bank with a selectable purpose of use – the basic export is free, even before you buy.
GDPR & German servers
Servers and database in Germany, files in the EU – your data is exportable or deletable at any time.
Services checklist
Five building blocks, clear roles: you can see who to bring in for what – energy consultant, architect, surveyor and so on. Nothing expensive gets overlooked.
You stay in the driving seat. The AI is your copilot.
Other tools want to replace you or make your mind up for you. Renaldo does the opposite: the AI calculates, checks funding eligibility, reminds you about deadlines and answers your questions – but every decision is yours. You keep full control of your building project.
- SAM answers your questions in plain language – day and night
- The AI checks bids for funding eligibility; you decide which one to award
- Your data is yours – GDPR-compliant, servers and database in Germany, files in the EU, exportable at any time
- Optional: bring a certified Renaldo retrofit coach into the team – but you don't have to

Will my access expire at some point?+
No. Your access is for life – pay once, use it indefinitely. No renewal, no follow-on costs.
Does the app help with funding applications?+
Yes. The funding calculator shows you which BAFA, KfW and federal-state programmes you are actually entitled to, and the tracker keeps an eye on the deadlines.
Do I need technical knowledge?+
No. SAM, your AI assistant, explains everything in plain language.
What happens to my data?+
GDPR-compliant, servers and database in Germany, files in the EU. You can export or delete it at any time.
Do I need Home Project to request a contractor quote?+
Yes. Contractor quote requests require Renaldo Home Project from the first request (€399 once) applies.
Does Renaldo Home Projekt include professional tools such as defect management?+
Yes. Home Projekt adds procurement and construction workflows to the free cost calculation, including site supervision, schedules, variations, invoice review and professional PDF exports. See the homeowner pricing matrix for details. Professional AVA-CSV exports and company branding are not included.
What does the funding eligibility check do for me?+
Upload a contractor's quote and Renaldo checks with AI, immediately, whether the works meet the German BEG funding guidelines. So you only award what will actually be funded in the end.
Can I start without Home Project?+
Yes. The Start plan is available – see the comparison on the pricing page.

CONNECT EARLY DESIGN AND PROFESSIONAL PLANNING
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.
