Renovation is a process of recovering and adding new up-to-date functions to the buildings that have aged and lost their functionality through time to extend their life cycles. This renovation is also known as the Second Construction. Buildings are unable to function when time progresses and surrounding conditions change. To breathe life and raise value to these buildings, the work of repairing and changing, yet preserving historical meanings and saving resources to these aged buildings have become important keywords for today’s Urban Architecture. HAEAHN Architecture is providing services that are related to buildings’ renovation plans.
