Some might call these items a form of cheating, but I believe every sim who wants to bathe in a trashy wooden bathtub has an unalienable right to do so, whether they can be bothered to craft anything or not. For those seeking an extra-trashy experience – a version in older wood and copper ('copper' may or may not be an euphemism for 'rust'). Toilet in matching colors and a cheap bowl that by some sorcery acts as a fully functional sink complete your rustic or medieval(-ish) bathroom.
One of the in-game vehicles made a buyable deco item and given two new color options and new footprint. Plus new wheels and tyres that look more realistic. Found in Decorative - Miscellaneous and costs 2500 simoleons. Because if it doesn't function like a car it should at least cost something like one.
A wooden tree-house for free-spirited nature lovers who want to live green, eat green and stay fit. Not only is it virtually bathed in green, it also features a green energy source - solar panel on the roof. The indoor space, though small, has all the basic necessities and some extras. Back door opens to a big awning where sims can play cards and craft. From there a ladder leads to the garden, that provides the green eating part, and below the deck there's a place to work on your fitness or just relax in the shade, screened from the street by shrubbery. Behind the garden some free space to put a telescope or a rocket building site if you feel like it.
