"In renovation, the biggest problem is not that something costs. The biggest problem is that the investor finds out too late how much it will really cost."
Important to understand
Why is a preliminary estimate not the same as an offer?
In renovation, the price depends on the condition of the property, installations, construction, permits, materials, and the organisation of execution. The calculator helps you understand the range. KOGI then assists you in converting this range into a clear plan, description, and feasible timeline after the inspection.
Hidden unknowns
Installations, statics, moisture, and the existing condition are often not visible at first glance — that’s why we check them early.
Designing before execution
Well-prepared plans and specifications mean less improvisation on the construction site and fewer costly repairs.
One interlocutor
One responsibility from idea to key — the end of shifting blame between the architect, supervision, and contractors.
Design & build method
What you get with the KOGI One-Path method
All phases of renovation under one roof — led by one team, along one path of responsibility.
Introductory meeting
Site visit, understanding needs, desires, and business goals.
Concept design
Measurements, existing conditions, space analysis, materials, 3D model, visualisations.
Documentation for permits
DPP, DGD, opinions, approvals, change of use or reconstruction, when necessary.
Project for execution

Transition to execution
Offer based on the description, contract, timeline.
Turnkey execution
Coordination of contractors, designer as site manager, supervision of details.
KOGI aftercare
