One way is to shift up the skip prior to the mid-height \tabucline
with a \\[-1pt]
. See below for 2nd approach.

\begin{document}
\begin{tabu}{ |[1pt] l | l l | l | l |[1pt] }
\tabucline[1 pt]{1-5}
\multicolumn{2}{ |[1pt] l }{ } & \multicolumn{3}{ |[1pt] l |[1pt]}{ } \\ \hline
& & \multicolumn{1}{ |[1pt] l | }{ } & \multicolumn{2}{ l |[1pt] }{ } \\ \hline
y & & \multicolumn{1}{ |[1pt] l | }{ } & \multicolumn{2}{ l |[1pt] }{ } \\[-1pt] \tabucline[1 pt]{3-5}
\hline
x & & \multicolumn{1}{ |[1pt] l | }{ } & & \\ \hline

& & \multicolumn{1}{ |[1pt] l | }{ } & & \\ \tabucline[1 pt]{1-5}
\end{tabu}
\end{document}
Alternately, if you want the thin line to bisect the thick line, then the approach: \\[-1pt] \tabucline[1 pt]{3-5}\\[-12.5pt]\hline
works.

Best Answer
Maybe you are interested in a result like the following (without bullet points):
In order to allow for automated line breaks in table cells, I used a
p
type and anX
type column. The latter is introduced by thetabularx
package and exactly occupies the width of the whole table minus the widths of the other columns. For manual linebreaks in table cells, I have used\newline
. I have also replaced the\hline
commands by the rules from thebooktabs
package in oder to have some more white space around them.
