Controlliamo l'area comune e la facciata.

Because Italian usually drops the final vowel of la before a word that starts with a vowel. This is called elision.

• la area → l'area
• la amica → l'amica

Also, area is a feminine singular noun, so the full article would be la.

Controlliamo comes from controllare.

In this sentence, it can mean:

• we check
• we are checking
• sometimes, depending on context, let's check

Italian present tense often covers several ideas that English separates.

A very important note: controllare often means to check, inspect, examine, verify, not just to control in the English sense.

Yes, it can.

The form controlliamo is the same for:

• we check
• let's check

So context and tone matter.

For example:

• Controlliamo l'area comune e la facciata. = We check / We are checking the common area and the facade.
• Controlliamo l'area comune e la facciata! = Let's check the common area and the facade!

Because Italian usually drops subject pronouns when they are not needed.

The ending -iamo already tells you the subject is we.

So:

• (Noi) controlliamo

Both are possible, but noi is often omitted unless you want emphasis or contrast.

For example:

• Noi controlliamo l'area comune, loro controllano il tetto.
  = We check the common area; they check the roof.

Because in Italian, adjectives often come after the noun.

So:

• area comune = common area
• porta rossa = red door
• edificio grande = big building

Putting the adjective before the noun is sometimes possible in Italian, but it usually changes the style or emphasis. For a normal phrase like this, area comune is the natural order.

Because comune is an adjective with the same form for masculine singular and feminine singular.

Here are the forms:

• comune = masculine singular
• comune = feminine singular
• comuni = masculine plural
• comuni = feminine plural

Since area is singular, you use comune.

Example:

• l'area comune = the common area
• le aree comuni = the common areas

Because Italian normally repeats the article when referring to two separate nouns.

So this is natural:

• l'area comune e la facciata

If you said:

• l'area comune e facciata

it would sound incomplete or unnatural in standard Italian.

Repeating the article makes it clear that you mean the common area and the facade as two distinct things.

Facciata is a feminine singular noun, so it takes la.

• la facciata = the facade
• le facciate = the facades

This fits a common pattern in Italian: many nouns ending in -a are feminine singular.

It is pronounced roughly like fa-CHA-ta.

A few useful details:

• cci before a gives a ch sound, like in chair
• the stress is on -cia-

So:

• facciata → fa-CHA-ta

A rough pronunciation is:

kon-trol-LYAH-mo

A couple of points:

• llia sounds like lya
• the stress falls on -ia-

So the word flows roughly as:

• con-trol-lià-mo

Often, yes.

English speakers can easily assume controllare means to control in every situation, but very often it means:

• to check
• to inspect
• to verify
• to monitor

If you want the idea of to control in the sense of to dominate / to have power over, Italian may use other expressions depending on context.

So in this sentence, controlliamo is much more naturally understood as we check or let's check, not we control.

You would need to make the nouns, articles, and adjective plural:

• Controlliamo le aree comuni e le facciate.

Changes:

• l'area → le aree
• comune → comuni
• la facciata → le facciate

So the adjective still agrees with the noun:

• area comune
• aree comuni
