من كتر الترميم، البيت مقفول.

Yes:

• من = from
• كتر = abundance, a lot, excess
• الترميم = the renovation / restoration work
• البيت = the house
• مقفول = closed / shut

So the structure is literally something like:

• From the abundance of renovation, the house closed

But in natural English, it means because of all the renovation work, the house is closed.

من كتر is a very common colloquial expression meaning:

• because of so much...
• from the sheer amount of...
• due to all the...

So من كتر الترميم means because of all the renovation.

You will hear this pattern a lot in Egyptian Arabic, for example:

• من كتر الشغل = because of so much work
• من كتر الزحمة = because of all the traffic / crowding

It is a fixed expression, so it is best learned as one chunk.

Because كتر and كتير are related, but they are not used the same way.

• كتير usually means a lot / much / many
• كتر here is more like abundance or excess, and it appears in the expression من كتر

So:

• من كتر الترميم = correct
• من كتير الترميم = not natural

A useful way to remember it is:

• learn من كتر as one set phrase
• do not try to build it using كتير

الترميم means renovation, restoration, or repair work, often especially on a building.

It is understood perfectly well in Egyptian Arabic, but it can sound a bit more formal than some very everyday alternatives. In casual speech, people might also say things like:

• التصليحات = repairs
• التجديد = renovation / renewal

So الترميم is correct and natural, but it has a slightly more formal or technical feel than some other choices.

Arabic often uses the definite article الـ in places where English does not.

So الترميم here does not have to mean a very specific the renovation in the English sense. It can simply refer to the renovation work in general.

This is very normal in Arabic. English and Arabic do not always use definiteness in the same way.

Also, because ت is a sun letter, الترميم is pronounced with assimilation:

• written: الترميم
• pronounced: roughly et-tarmīm or it-tarmīm

Not el-tarmīm.

Because in Arabic, present-tense sentences like this usually do not use a spoken word for is.

So:

• البيت مقفول = the house is closed

This is called a nominal sentence.

In the present tense, Egyptian Arabic normally just puts:

• the noun/topic
• then the description

Examples:

• الباب مفتوح = the door is open
• الجو حر = the weather is hot
• البيت مقفول = the house is closed

But in past or future meanings, Arabic does use other forms.

مقفول can mean:

• closed
• shut
• sometimes locked

It comes from the verb قفل = to close / lock.

In a sentence like this, مقفول usually means the place is not open / not accessible, which is exactly what you would expect during renovation work.

So for a building, مقفول is very natural.

It does not always have to mean physically locked with a key. Often it just means closed off.

Because بيت is a masculine noun in Arabic.

Adjectives and similar descriptive words have to agree with the noun, so:

• البيت مقفول = correct
• البيت مقفولة = incorrect

Compare:

• البيت مقفول = the house is closed
• الشقة مقفولة = the apartment is closed

Here شقة is feminine, so the form changes to مقفولة.

It is best understood here as a passive participle being used like an adjective.

It comes from the verb قفل.

So very roughly:

• قفل = to close / lock
• مقفول = closed / shut / locked

In real usage, learners can safely treat it like an adjective in sentences such as:

• الباب مقفول
• المحل مقفول
• البيت مقفول

This pattern is extremely common in Arabic.

Because Arabic often puts background information or the reason first.

So:

• من كتر الترميم، البيت مقفول

puts the cause first, almost like:

• Because of all the renovation, the house is closed

This is very natural.

You could also say:

• البيت مقفول من كتر الترميم

That also works. The difference is mostly about emphasis:

• من كتر الترميم، البيت مقفول = foregrounds the reason
• البيت مقفول من كتر الترميم = starts with the main fact

Both are understandable and natural.

It sounds most natural as colloquial Arabic, and it fits Egyptian Arabic well.

The most clearly colloquial parts are:

• من كتر
• مقفول

Other Arabic speakers would very likely understand it, especially in many spoken dialect contexts.

A more formal or MSA-style version would be something like:

• من كثرة الترميم، البيت مغلق
• بسبب الترميم، البيت مغلق

So the original sentence is good colloquial Arabic, not formal written MSA.

Yes, but the tone changes.

• بسبب الترميم = because of the renovation
  This is more neutral and a bit more formal.
• من كتر الترميم = because of so much renovation / because of all the renovation
  This sounds more colloquial and more expressive.

So:

• بسبب الترميم، البيت مقفول = perfectly fine
• من كتر الترميم، البيت مقفول = more conversational and more vivid

They are close in meaning, but not identical in feel.

A natural pronunciation would be roughly:

men ketr et-tarmīm, el-bēt maʔfūl

A few notes:

• من is often pronounced men or min
• الترميم becomes et-tarmīm because the ل of الـ assimilates to ت
• البيت is usually el-bēt
• ق in مقفول is often pronounced as a glottal stop in Egyptian Arabic, so maʔfūl

So if you want a learner-friendly approximation, you can say:

men ketr et-tarmīm, el-bēt ma'fool

That will get you very close.
