    Beautiful! I think all these have a place in our society. Garage apts., tiny/small homes on trailers or slabs/foundations. It is up to your own personal needs/wants. I like this idea of being able to generate some income which is always a plus.

    Glad to see the use of mirrors finally. They are such an expander for small homes, making them seem twice as large as they really are if they are placed right.

    Good show!!!!

    I am moving to my sons house into a single wide garage that is 25 feet long
    It will be converted with my input after I move there. I m notsure how much of a kitchen. I can put in that space. I need design Ideas.

    Having looked at the photos, I fail to see where “lots” of wasted space is?
    Maybe the kitchen could have been arranged a bit differently… but what works for one person won’t work for another. There aren’t that many photos of different perspectives of same room so really hard to tell how much (lots) wasted space there is… but, if you wouldn’t use it anyway then it isn’t wasted is it?

    Looking at this, I am not so thrilled. The place is too stuffed in the living room, and overall gives the feeling of being too stuffed. Living tiny shouldn’t ‘feel’ like it. I say for starters, get rid of the coffee table in the center of the living room and go with two (or one) end table. Also that pile of storage and lamp shade at the right of the living room needs to go away. Black furniture also makes the space seem smaller. The couch is imposing and overstuffed. A sleeker Ikea, or some kind of ‘Euro’ version would be more suitable for the space without sacrificing comfort.

    The kitchen is dark without any window and feels like you are walking into a cave with lantern affixed into the ceiling to keep away the bogeymen. The aesthetics can be improved a lot here by simply getting rid of that big clunky refrigerator and going with an under the counter version. Yes, it is a lot smaller, but if this is a mother in law, does one person really need that much food? 🙂 I would also figure out how to close up and creatively use that space between the oven and right counter top. Looks very awkward, especially with that cabinet hanging over it. Perhaps replacing the cabinet with open shelving would improve things? Doing away with the yellow and going with a crisp white on the walls here would do a lot to escape the overall yellow enclosed feeling that the lighting only adds to. I think the yellow could be fine in the kitchen if there was a window, but without the window, the yellow is it’s downfall.

    The plant next to the bed is imposing. An improvement – putting a narrow plant stand next to the wall and door and have a small hanging plant over it also. Lightening things up with lighter coloured furniture and one or two accent coloured walls along with crisp white instead of beige also gives the illusion of more space. The use of the mirrors is a plus here so they do have that going for them. I have to say, I really love that mottled gray, black and white floor, just not in THIS application. A light tile or carpet would improve the space feel.

    I think a room that looks crowded seems smaller. That’s why homes that are “staged” to sell remove all unnecessary pieces of furniture, knicknacks, etc. Looking around my own living room right now I see way to much “stuff” so I’m as guilty as the next person of trying to fit too much into a house. But I think the garage/studio would be great if some of the unnecessary items were removed.

    I really love the creativity of garage conversions. As noted in the above comments above…I would do this and that. This is a persons taste and preferences to their decor choices. In a small space, which I do live in, I choose not to have a lot of “possessions” surrounding me. In turn, the homeowner, I’m assuming, chooses to surround themselves with what makes them happy. The one thing I would look into if the funds are there and the design will allow for it, would add a window. All in all, I love the house. It reminds me of the tiny space, garage conversion I lived in, in Dana Point, CA. My space was all wood that allowed me to hang my surfboards from the ceiling. Good times.
