Greetings Pavel,
at its heart, LilyPond very much encourages «horizontal thinking»:
it’s easier to enter one melodic voice, then another, then another.

However, there are a few ways to enter music section by section like
what you’re looking for. The first one is to use \context Staff (which
can re-use an existing Staff rather than create a \new one every
time):

%%%%%%%%%%%%%%%

FirstSection = <<
  \context Staff = "voice" \relative c' {
    c2 d e1
  }
  \context PianoStaff = "piano" <<
    \context Staff = "right" \relative c' {
      <g c g'>2 <g d' g> <c e g>1
    }
    \context Staff = "left" \relative c {
      \clef bass
      e2 b c1
    }
  >>
>>

SecondSection = <<
  \context Staff = "voice" \relative c' {
    a'2 f4 a g1
  }
  \context PianoStaff = "piano" <<
    \context Staff = "right" \relative c' {
      <a c f>2 <c f a> <e g c> q
    }
    \context Staff = "left" \relative c {
      \clef bass
      f,4 g a b c2 c
    }
  >>
>>

\score {
  {
    \FirstSection
    \bar "||"
    \SecondSection
  }
}

The second trick you may be interested in learning, is \parallelMusic
(which allows you to enter polyphonic music with every voice at once).
Have a look at this chapter:
http://lilypond.org/doc/stable/Documentation/notation/multiple-voices#writing-music-in-parallel

Good luck!
