New apartment or old apartment, what is the first decision?

The first decision between a new apartment and an old apartment is not material, but the condition of the existing plumbing line: in a new building the line is already set up to a current plan, while in an old building the line is checked first, then material selection follows. If this order is reversed, the chosen material may not match the existing line.

The difference between a new apartment and an old apartment is therefore in the infrastructure before the look; the 2015 example apartment in Yukarı Ayrancı shows this.

What determines the first 5 decisions in a new and an old apartment?

Five decisions are made in order; in a new apartment some of them come already resolved, in an old apartment all of them open up on survey day.

Floor levelFlat, no extra screed neededDeviation can appear in the old screed
Electrical lineCompliant with current regulationLine count and capacity are checked
Material selectionCan be made as the first decisionNot made before the infrastructure is clear

Which approval process is required in an old apartment?

If a wet area is to be moved in an old apartment, the management approval process we explained in our apartment renovation permit and approval article comes into play; this step is usually not needed in a new apartment because the wet area location is not changed.

This difference also explains why the site schedule in an old apartment takes longer than in a new apartment.

Which is the right choice?

There is no right-or-wrong choice between a new apartment and an old apartment; both can reach the same result from a different starting point. The difference is that an old apartment has one extra step: infrastructure check.
