Daniel,
Thanks for fast reply. But I looks like lvextend appends space after LV.
And after running lvextend we will get following:
[25GB LV] + [20 GB free space]
free space added after original LV.
But we need to prepend free space before original LV:
[20 GB free space] + [25GB LV]
free space added before original LV.
Thanks,
Alex

I don't know what a LV with free space should be good for,
but you can achieve this by lvextend.
#lvs /dev/mapper/system-home
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
home system -wi-ao---- 25.00g
# df -h /home
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/system-home 25G 8.0G 16G 34% /home
# lvextend -L +20G /dev/mapper/system-home
Size of logical volume system/home changed from 25.00 GiB (6400 extents) to 45.00 GiB (11520 extents).
Logical volume home successfully resized
# df -h /home
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/system-home 25G 8.0G 16G 34% /home
# lvs /dev/mapper/system-home
LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert
home system -wi-ao---- 45.00g
