Preservation Building
A property with exceptional historical, architectural, or cultural value where engineering meets heritage to create an irreplaceable asset.
What is a Preservation Building and Why Does it Exist?
A preservation building is a property with exceptional historical, architectural, or cultural value, designated by authorities for protection. The field of preservation ensures that a city’s built heritage is not erased by generic modern construction but is instead integrated into it, creating a rich and storied urban environment.
Hemli Group’s Professional Perspective
For us, preservation is “Engineering with Respect.” It is the most fascinating meeting point between the past and future technology. We don’t view preservation as a limitation, but as an opportunity to create a real estate masterpiece. However, we state with complete integrity (Honesty): preservation is a massive engineering and financial challenge. It is a path where the developer commits totally to the structure, taking on complex engineering risks to create an irreplaceable asset.
Legal Meaning & Statutory Process
Working on a preservation building is subject to much stricter legal constraints than standard construction:
Preservation Levels
The law distinguishes between “Standard Preservation” (allowing some changes) and “Strict Preservation” (prohibiting any changes to the facade or specific interior details).
Documentation File (Tik Ti’ud)
Every project begins with an in-depth historical and architectural study analyzing every stone, window, and ornament. This is the foundation for all planning approvals.
Preservation Committee
Plans must be approved by a municipal preservation committee, which meticulously examines finish materials, color palettes, and work methodologies.
Conditional Building Rights
Often, municipalities grant additional building rights (on the roof or an adjacent plot) to compensate for high preservation costs, but these are contingent on perfect execution of the preservation work.
Developer Responsibility: Why Take the Risk?
A developer entering a preservation project assumes extraordinary engineering and financial responsibilities:
Engineering Complexity (Structure Suspension)
In many cases, we are required to “suspend” the historic building in mid-air using temporary steel structures to allow for underground parking excavation. This is a high-risk engineering feat requiring surgical precision.
Double Construction Costs
Using original materials, expert stonemasons, and restoring historic carpentry and ironwork—these factors increase costs by hundreds of percent compared to standard builds.
Responsibility for Heritage
The developer is legally responsible for ensuring the building remains undamaged. Any crack or damage to a preserved element falls under the developer’s direct legal liability.
Timelines
Approval and execution processes in preservation are significantly longer due to the need for tight supervision by municipal preservation departments.
Hemli Group’s Operational Approach
As a company specializing in complex projects (such as Derech Beit Lechem and Osishkin 53), we operate with “Zero Compromises”:
High-Level Engineering
We employ Israel’s leading engineers for structural preservation and foundation work. Our ability to excavate under an existing structure while maintaining absolute stability is our trademark.
Planning Integrity (Honesty)
We reflect the project’s complexity to residents and partners from day one. Preservation requires stamina, and we are here to manage it professionally.
The Art of Restoration
We work with the finest craftsmen—stonemasons, carpenters, and restoration experts—to ensure the final result is faithful to the original while providing 21st-century luxury.
Risk Management
Our operational model includes constant technological monitoring of the structure during execution to ensure absolute safety for the building and its surroundings.
