Well almost any surface can be painted of course.
But the whole furniture is a big job, also professional
preparation of the surfaces inplace etc.
If you intent to ripp out the furniture and replace it
it would probably costs even more. Most is plywood
LEGO, screwed and glued, so tearing apart without
scratches is a delicate and time consuming work
In production cats the furniture is built as block
in the factory and then placed / fitted in the hull
before the deck
is set on topp. Usually they are not
intended to be removed or replaced by the owner,
so some connections are not dismountable without
brute force or cutting screws, simply because they
are in uacessible locations.
I am not sure about labor tarifs in AU, but I guess it
could add a significant bill to the budget if you do not
intent a DIY
Of course there are great craftmen in Asia
, where labour is cheap
and you can refit
anything you want for reasonable prices.
Probably you need to check that the parts
you want to alter are not
meant as enforcement for the structure too..
If its only the paint on topp... Probably doable somehow.
Another way may be to just set some accents and brite up the interior e.g by painting or covering large wall elements only (white ultraleather ore somthing brite and easy to clean), and enjoy the contrast to the left over dark furniture.
It may then look more like a condo than like a wooden coffin.
For my taste Lagoon uses too much structured wooden surfaces besides the real furniture as panels, walls etc. I would also prefer less wood, but then high quality.
