Tadilat gürültülü; öte yandan kısa sürecek.

Because Turkish often leaves out the verb to be in the 3rd person present.

So:

• Tadilat gürültülü = The renovation is noisy

There is an understood is, but Turkish does not normally say it explicitly here.

This is very common in Turkish nominal/adjectival sentences:

• Hava güzel = The weather is nice
• Ev büyük = The house is big
• Tadilat gürültülü = The renovation is noisy

If you wanted past or future, then Turkish would usually add something:

• Tadilat gürültülüydü = The renovation was noisy
• Tadilat gürültülü olacak = The renovation will be noisy

Tadilat means renovation, remodeling, or repair work, depending on context.

It is often used for construction or improvement work in a house, apartment, office, or building.

Examples:

• Evde tadilat var = There is renovation work in the house
• Bina tadilatta = The building is under renovation

In your sentence, tadilat is the subject.

Gürültülü means noisy.

It comes from:

• gürültü = noise
• -lü / -lı / -li / -lu = a suffix meaning with, having, or sometimes characterized by

So gürültülü literally means something like with noise or full of noise, which becomes noisy in English.

Other similar examples:

• tuzlu = salty
• şekerli = sugary / with sugar
• sisli = foggy
• dumanlı = smoky

Öte yandan means on the other hand, however, or that said, depending on context.

It is used to introduce a contrasting or balancing point.

In this sentence:

• Tadilat gürültülü; öte yandan kısa sürecek.
• The renovation is noisy; on the other hand, it will be short.

So the speaker is balancing a negative fact with a more positive one.

A rough breakdown is:

• öte = other / further side
• yandan = from the side

But as a whole, you should learn öte yandan as a fixed expression.

Yes, in many situations you could, but the tone changes a little.

• ama = but
• ancak = however / but
• öte yandan = on the other hand

Compare:

• Tadilat gürültülü ama kısa sürecek.
• Tadilat gürültülü; ancak kısa sürecek.
• Tadilat gürültülü; öte yandan kısa sürecek.

All are possible, but öte yandan feels a bit more formal or balanced, as if the speaker is weighing both sides. Ama is the most everyday and conversational.

Sürecek comes from the verb sürmek, which here means to last.

So:

• sürmek = to last
• sür-ecek = will last

The suffix -ecek / -acak is the future tense suffix.

Because the last vowel in sür- is a front vowel, the form is -ecek, not -acak.

So:

• sürecek = will last

Then kısa means short.

Together:

• kısa sürecek = it will last a short time / it won’t last long

This is a very natural Turkish way to say it.

In Turkish, adjectives can sometimes function in ways that sound a little adverb-like in English.

Here, kısa describes the duration, so kısa sürecek means:

• it will last a short time
• more naturally in English: it will be short or it won’t last long

You may also hear a fuller version:

• Kısa bir süre sürecek = It will last for a short time

That version makes the idea more explicit:

• kısa bir süre = a short time

So kısa sürecek is a compact, natural form.

The sentence is describing two different things:

• Tadilat gürültülü = the renovation is noisy
• öte yandan kısa sürecek = on the other hand, it will not last long

The first clause gives a current/general characteristic: the renovation is noisy. The second clause talks about duration extending into the future: it will last only a short time.

This kind of tense combination is normal in Turkish and in English.

Yes. The subject is understood to be the same as in the first clause: tadilat.

So the full idea is:

• Tadilat gürültülü; öte yandan tadilat kısa sürecek.

But Turkish often leaves out repeated subjects when they are obvious from context.

This is very common and natural.

The semicolon separates two closely related independent clauses.

It shows:

• the two parts are connected,
• but there is also a slight pause and contrast.

So it works well with öte yandan, which introduces a balancing idea.

You could also see a comma in less formal writing, but the semicolon gives the sentence a cleaner, more structured feel.

It can mean both, depending on context.

Common meanings of sürmek include:

• to drive
  • Araba sürüyor = He/She is driving a car
• to last
  • Toplantı iki saat sürdü = The meeting lasted two hours
• in some contexts, to spread/apply
  • Krem sürmek = to apply cream

In your sentence, sürmek clearly means to last.

Yes, for everyday conversation, that version may sound more casual and common.

• Tadilat gürültülü, ama kısa sürecek.

This is very natural spoken Turkish.

Your original sentence with öte yandan sounds a bit more formal, thoughtful, or written. Neither is wrong; they just have slightly different tones.
