DEIKON Construction Cost

DEIKON is an architect-developed construction cost estimation app for new-build residential projects in Greece. Created by a practicing architect, DEIKON helps homeowners, developers, investors, and construction professionals understand how construction costs are structured before committing to a project. Adjust the building size, basement areas, terraces, balconies, energy features, technical systems, and other project parameters to see how each decision affects the total cost. Identify the main cost drivers and understand where your budget is going. DEIKON also considers land and site conditions, including terrain, soil characteristics, site access, and other factors that can significantly affect construction costs. The app makes the structure of construction costs more transparent — including construction categories, professional fees, additional expenses, and often overlooked cost items. This allows you to compare different scenarios, make better early-stage decisions, and reduce unnecessary costs before moving forward. For developers and professionals, DEIKON supports early-stage project evaluation by helping estimate total project costs and assess potential feasibility and profitability. The cost model is currently focused on new-build residential projects in Greece and may expand to other Mediterranean countries in the future.
