THE OPERATING SYSTEM FOR RESIDENTIAL CONSTRUCTIONMore homes.
More homes.
Less friction.
One system.
For developers, housing companies and the teams planning and delivering their new-build and renovation projects. RENALDO connects building data with predefined work items, prices and durations. Review and refine the starting point, then reuse it for cost planning, tendering and scheduling. Spend less time preparing data and reach informed decisions sooner.

=A construction schedule that writes itself — instead of a spreadsheet that is out of date by week two.
Because cost and schedule hang off the same model, you see immediately what a delay costs – and what a decision means in time. That link simply does not exist elsewhere: scheduling tools don't know the costs, costing tools don't know the rhythm of the site.
And before any of that begins: three-click feasibility tells you before you buy whether a plot stacks up — right down to the maximum land price it can carry. See it for developers →
What is Renaldo?
In short
What is Renaldo?
Renaldo is the operating system for residential construction: costing, planning and building from one data core – new build and retrofit, from single-family homes to whole housing portfolios. Four worlds, one project status: housing professionals (developers, housing companies, asset managers), private building & renovation (homeowners, professionals, partners), construction companies and the trades all work on the same project. On top of that comes knowledge: practical know-how and a certified retrofit-coach qualification.
- for housing (developers, housing companies, asset managers): analyse stock and plots, build and retrofit serially, apartment-block costing, tendering, construction, operation and sale – the portfolio under control.
- for professionals: import building data, plan the works, tender, analyse bids, coordinate trades, inspect, manage defects, check invoices – new build & retrofit, as many projects as you like.
- for homeowners: a running overview of costs, funding, decisions and dates – new build or retrofit, all in one app.
- for partners: advice and referrals based on live data and fast service, instead of gut feeling and long waits.
The whole residential project – in three steps, in one app.
From the first cost estimate through contract award to the final invoice – Renaldo covers every phase: with real contractor prices, AI at every step, and everyone working on the same project.

Start for free07IFC 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.

Cost and schedule from one model.
Renaldo thinks about every residential project from the end backwards. The two questions that actually matter in construction – what does it cost and when will it be finished – are answered from the same building data. Which is why the answers always agree.

From material item to timely ordering.
Reuse your article library
Maintain article number, manufacturer, supplier, unit and price for materials. Import Excel and CSV lists into your library with column mapping and preview. Material data stays connected to line items and work preparation.
Include lead times in the schedule
Set lead times in working days for materials, line items, trades and company defaults. Order planning shows sampling, release and latest ordering dates before installation. Changes to source data flag existing orders for review.
Plan & Calculate covers material items and library import; Schedule & Quality covers order planning. The contractor package also includes bid costing, the 3D offer room and subcontractor management. Packages from the client tender require Bid costing and Tender & Account.

HOUSING · PORTFOLIO & STRATEGY
Compare climate targets and costs over time.
Which package suits the building and meets the climate target? Compare its carbon trajectory with the selected target pathway, identify gaps and prioritise portfolio investments.
Lifecycle costs beyond construction
Assess construction and measure costs for materials and labour, maintenance, replacement and residual value alongside energy and carbon costs. Adjust horizon and discount rate, compare present value and annual costs, and assess carbon abatement costs.
Operational and embodied emissions
Reviewed component quantities add embodied emissions in the project. Sources, measured data and estimates remain traceable. The public demo shows climate pathways and simplified cost analysis; it does not replace a verified building lifecycle assessment.
Included in Housing Portfolio and Housing Komplett. Housing Komplett adds procurement, scheduling and renovation-related resident communication. Operate alone does not include portfolio strategy.
