The concern
The project collapses economically, shortly before the building permit application.
What we did
Holistically review and rebalance the volume, basement, construction, areas and return-on-investment model.
What was the goal?
A rebalanced project with measurably improved returns.
What was the initial situation?
The project was in the transition phase from preliminary design to building permit application and was architecturally quite advanced. An external cost estimate revealed that the actual construction costs were significantly higher than the initial estimates, creating a clear imbalance between investment costs, achievable living space, and expected return on investment. At this malleable stage, it was still possible to take corrective action.
They improved our project with measurable numbers, not promises.
Owner: Thalwil ZH
What have we accomplished?
An independent site analysis revealed that development potential had not yet been fully utilised. Based on this, I examined the project in all relevant areas: floor plan and space organisation, circulation areas, ancillary rooms, basements, structural systems and wall constructions, as well as the cost-benefit ratio. Areas with high costs and no direct contribution to revenue were identified and discussed with the owner.
What was the result?
The implemented optimisation measures resulted in a substantial economic improvement of the project: more living space, lower construction costs and a measurably better return on the invested equity.
This is how the collaboration went
01
Get to know
Discuss key performance indicators, cost structure, and optimisation goals.
02
Site and zoning analysis
Examine potential development reserves in relation to the projected development.
03
analysis
Examine the floor plan, basements, construction and energy efficiency.
04
catalogue of measures
Develop and deliver optimisations with transparent impacts.
05
Diploma
Ensure the transition to further planning and initiate implementation.
Plain text from the project
A thorough 360-degree analysis achieves before the building permit application what is no longer possible later.
What was the added value for the customer?
More living space
Higher yield with the same building volume.
Reduced construction costs
Reduced effort with the same or improved quality.
Improved return
Substantial economic improvement.
Increased planning certainty
A clear basis for decision-making in the execution phase.
