Building and buying guide

Old building or new building?

Building age is an important context; but it is not a quality or safety provision alone. A new building may not be well planned or may have implementation problems; An old building can offer a strong life with regular maintenance, qualified planning and correct improvements. The decision should be based on verifiable features, not on the label.

One-minute summary

What to remember before deciding

  • Use the year of construction as the start of the decision; not as a security consequence.
  • Verify license, project, ground and carrier system questions with expert review.
  • Compare layout, daylight, materials and common area quality regardless of building age.
  • Research the past maintenance together with the common expenses and renewal needs of the coming years.
  • Add the purchase price to the same scenario as renovations, energy use, dues, and conversion uncertainty.
01

View building age as a start to research, not a label

Year of construction; It raises questions about the legislation in force, the techniques used and the duration of use of the building. But just knowing the age; It does not indicate the nature of the project, the quality of implementation, subsequent interventions or current performance.

There may be project and application flaws in the new building, and wear and maintenance deficiencies in the old building. Use a combination of documentation, observation and appropriate technical investigation rather than shorthand judgments of 'new is safe' or 'old is risky'.

Basic principleAge determines what questions you ask; It is not the answers themselves.

In order to obtain a conclusion about structural safety, a building-specific examination is required by authorized technical experts and with an appropriate method.

02

Examine the technical and official file separately from the age information

Turkish Building Earthquake Regulation describes the minimum conditions for the design of new buildings and the evaluation of existing buildings. The fact that a building was built after a certain date does not alone mean that the project, application and current situation are verified.

Gather up-to-date information on permits, building permits, approved projects, renovations and current use. If there is interference with the carrier system, obvious damage or safety concerns, do not settle for general observation; Request appropriate engineering review.

  • Construction, license and building permit dates
  • Compatibility of approved project and existing use
  • Interventions in the load-bearing system or common areas
  • Coverage of past repairs, retrofits and technical reports
  • If deemed necessary, performance evaluation in accordance with the legislation
03

Compare plan and quality of life with period characteristics

Large rooms, wide openings and strong material character can be seen in old buildings; On the other hand, storage, parking, accessibility, wet areas and plumbing layout may not meet today's needs. While elevators, parking lots and up-to-date systems provide advantages in new buildings, net usage area or room rates may be weaker than expected.

Apply the same life scenario to both options. Evaluate furniture placement, light, ventilation, noise, privacy, entry and common area experience on-site; Do not rely solely on general assumptions attributed to building age.

04

Ask about past maintenance and future expenses at the same time

Roof, facade, elevator, plumbing and common area renovations may be approaching in the old building. In a new building, site services, technical systems and post-warranty maintenance may increase regular expenses. Evaluate the dues amount not by itself, but by which service and which reserve it covers.

Energy performance does not depend solely on building age. Façade, insulation, windows, heating-cooling system, usage style and maintenance status are all effective. See available documentation; If possible, compare past invoices and terms of use for actual consumption.

  • Major common area works completed and planned
  • Management budget, dues scope and extraordinary expenses
  • Roof, façade, water, wastewater, electricity and elevator history
  • Energy identity certificate and actual consumption if possible
  • Necessary interventions in the independent section in the short and medium term
05

Make the decision with total cost and uncertainty scenario

The low purchase price of an older home can be increased by extensive renovations and upcoming building expenses. The higher price of a new home may offer a different cash flow thanks to move-in ready use or more predictable short-term maintenance. In both options, bring the sales price, transaction expense, intervention, dues and reserve side by side.

Do not treat the conversion expectation as a definite gain. See zoning, entitlement, reconciliation, financing and duration uncertainties in separate scenarios. The right structure for you; It is not the newest or the oldest, but the option that fits the need with its verified qualities and manageable uncertainty.

Frequently asked questions

Clear, concise answers

01Is the new building safer against earthquakes?

Building-specific security results cannot be given solely by looking at the year of construction. The project, ground, application, subsequent interventions and current situation must be evaluated by authorized technical experts with an appropriate method.

02What is the most important check when buying an old building?

A single check is not enough. The current official and technical file, current situation, maintenance history, upcoming common expenses, plan of the independent section and total intervention budget should be examined together.

03Does the energy identity certificate show actual consumption?

The energy identity certificate provides a standard classification of the energy performance of the structure; It does not alone show the actual bill based on personal usage habits. If possible, past consumption and system status should be examined separately.
