Y'know a garage home plan isn't such a bad idea

[Dirtyhip]

Someone suggested a carriage house.  You guys are often very smart  We have been going back and forth on the plans, and I found this one.

I kinda like this a bit better.  The views from a second story would be pretty killer on our lot.  We need to make a good decision, before we go to drafting.  

@Thaddeus Kosciuszko, tell me issues you think this house might have.

https://www.monsterhouseplans.com/house-plans/any-style/877-sq-ft-home-2-story-2-bedroom-2-bath-house-plans-plan40-595.html

The garage doors will face north.  We will add another window on the living room side (which is west).  Bed can be on the east wall, which is good for natural energy.

BIG bike storage.  Room for a trailer, and a vehicle.  No carport needed.  This will retain lots of land space too, for veggie gardening.  

Also, I can run around without clothes, and not really need much blinds.  2nd story, and the homes around are all one story. 

 

 

[Dirtyhip]

and make the home a smidge larger footprint.  A little over 900 sq ft of footprint.

[Randomguy]

What is so great about that one room?

Ok, I have looked, and I like it.  However, do you always want to be walking up stairs, every time, to get to your living area?  Houses over garages tend to be cooler/colder, as well, unless you heat the garage.

What did the other plans look like?

Do you mean the garage room?  One side is workout zone and bikes, the other is car

The one they call the "great room".  I rolled my eyes hard just there, but in a fun way.

[Randomguy]

Ok, I also don't understand how a design would have a whole wall with no fucking windows.  Wth?  Natural light is a good thing, tell them to design it again.

OH, damn....I can be dense.  I am too literal.  

It is great, because it is large, I guess.

I hadn't considered the heat issue.  Hmmm. The garage should be insulated.  The temps in the town are not like this one.  It is much warmer there.  

The long skinny part of the garage will be finished and heated. It will be a workout room.

[Dirtyhip]

Stairs should be ok.  Remember, I am a badass.

Also, I plan to remain ambulatory.  If that changes, we can install a chair lift.

Ah.  It is a consideration, though, I very briefly lived in a room above the garage, that room was 20 degrees cooler in winter than the half that wasn't above the garage.  Yeah, the insulation sucked, although every time that door opens, cold wintry death gets blown in.

I think that you can install them anywhere.  You customize, right.  

We plan to add a window on that side.  The bedroom won't need another window, cause our bed will be there.  Or, we can add two smaller windows t the side of the bed, like above the night tables.

[Dirtyhip]

Just now, Randomguy said:

Insulation in the ceiling of the garage.  That should help.  Heat rises too.

You are more badass than me.  I have had bad knees forever, and it sucks to have to climb when the knees aren't having it.

I love the idea of the heated workout room, but you probably aren't going to heat it all the time, are you?

[Dirtyhip]

Metal roof, and regular height ceilings on the top floor.  Cathedral wastes heat.

Most likely not.  We could even do something low budget like cadet wall type, and turn 'em off.

Keep the questions coming.  I have to think of everything before the draft table.  I don't want changes, later.

and no fucking skylights.  They are a waste of energy and tend to cause problems.  I had one at the forest house, and it sucked.

You should probably get skylights.

Are you doing a wood fired stove?  Geothermal heat?  Solar panels?  Where is the pantry?  Servants quarters?  Coach house?

I also don't see a stable for TER's horses when she comes visiting.

No skylights

I would like a stove, my husband isn't thrilled with that idea. He wants to invest in a nice generator, instead.  The wood gathering is a pain.  We plan to install a pantry next to the last cabinet.  Like, extend the kitchen cabs slightly to accommodate a small pantry.

Horses are bullshit. They are not allowed anywhere near our property.  Dogs have free reign tho. 

Servants quarters? Guests are expected to help.  I have some gloves for you, when you visit for trail work and gardening.  HAHA

Re consider the heat issue as garage doors are not particularly well insulated, nor do they seal well to keep out drafts.  Any room with garage doors is going to be an energy hog if you try to heat it.  If you do not heat it then you will need to insulate the rest of the house from it.

[Wilbur]

The idiot that suggested a carriage house because of your initial want list has probably built a couple hundred homes.  That is what you need if you want maximum utility space on a small lot.  No skylights.  I never met one that didn't have leak potential.  Insulate with closed cell foam between floors.  That will prevent exhaust gas etc from entering the living section and will keep your toes toasty warm.  I would nix the bay window in the kitchen, add a sliding glass door to a deck with stairs to the back yard.  convenient and you always want at least two ways out of a home in case of fire. 

[bikeman564™]

I like that house DH

[Airehead]

I agree with insulating well between the garage and the house.  Overall I love the idea--- and if you put the lift in it will allow you both to age in place.  With that in mind, make at least one shower roll in for when you are really old.

[Green Grass]

Dirty Hip:

What is going on here?  Last I remember you own a couple homes and were in a big hurry to terminate the mortgages.  

[ChrisL]

My sons room is over the garage and it is insulated.  His room is the hottest in the summer and coldest in the winter... Being over such a large open space does affect the temperature of the house.  The other issue for me is always having to go up stairs. Groceries have to go up, all furniture has to go up, buy a new...... it has to go up.  Where will laundry be, in the house or garage?

 I think its a smart use of space and you do have privacy up there though.

We can sell the large country rental and pay cash for the build. It's all ours. We can either keep our residential home here or sell that as well and invest the cash. My plan is to pay all cash for the build.

This home is for a new lot we bought this summer. Retirement home in MTB and recreational paradise.

Dumwaiter for grocery could be installed. Laundry is a stacked unit on top floor. We intend on paying people to help us move things in. When we need new shit, we may just have to pay. 

Laundry is planned for the top floor. 

Really, if we become truly disabled, we may have to move anyway. We won't need a gigantic garage for toys or a private workout room. 

I hadn't considered Wilburs fire issue. Hmmm. It is almost surrounded by forest, but there will be no trees near the house. Just fruit trees that we intend to keep small.

Also think of wiring short (uncommon) or laptop/phone battery fire.  Most house fires start within the home.

Stairs are great exercise and you are right, if you can't do them, it would be time to move.

Nice.  Congratulations.

Here's another thought.  Build your living space in a basement with garage above.  Make the elevation of the house appear as if it is a home, not a garage.  Benefits?  The ambient temp below ground is fairly constant and will require a minimal amount of heating in winter and cooling in summer.  Dumbwaiter is a capital idea.

Closed cell?  Closed cell is sprayed in place and it expands.  There is very little heat loss as there is zero circulation of air.

Sounds like you are cool with the concept then.  Just posting concerns to consider but if you really like the lay out then the nit noid concerns can all be overcome.

We have a 2 story now but just the bedrooms are upstairs. Bringing everything up would be a PITA for me but that's just me.

Good point, no they put that fluffy pink stuff you roll out and just in the garage ceiling. Apparently I have a 2nd phase unit. 1st phase didn't even do that and that room is like an icebox/sweatbox.

That should be outlawed in a garage.  It does nothing to prevent Co2 penetration of the living space and very little for thermal protection.

We want space for a smallish rec trailer and truck parking on a lot that is semi triangular.  Front entry garage.  The lot is very small.  like 60 x 100. It gets big at the back.  There is no access from the back. That is private property.

Lots is Oakridge are pretty darn small, and one of our requirements is being able to walk or ride to the grocery store. There are bigger lots up by a gold course, but the CCRs all want mini Mcmansions.  PLus the ride up to that zone is a death trap.  Big hill, no shoulder. Steep drop off the side and a guardrail. All the houses we saw for sale were garbage, or ridiculously huge and expensive.  Nothing fit our needs.  Most quaint homes had a one car garage. One car?  Where can you fit 12 bikes?  

[Kirby]

No practical suggestions from me, because I'm no good at that sort of thing, but I like the design.   But I liked the design of the other one too.   I doubt you could go wrong with either one.

I love these comments.  Keep the negative points coming.  I need to carefully consider everything, before the build.

Oh, and metal roof is what I would prefer as well.  Standard height ceilings, with an insulation barrier, in the roof area.  I hope this will dampen sound and insulate as well.  I do love the sound of the rain on a metal roof.  I was afraid of that, when we put a metal roof on our current place, but I love it now.

Ok, I remembered another couple of things about living above a garage, assuming you may actually keep a car in there.  The first is that you will need lots of sound insulation, especially if someone else will open the garage door and start/warm up a car in there while you are attempting to sleep.  I agree about the closed cell, too, I remember that when the garage door was opened, even if only briefly, then the upstairs would cool down noticeably after a while.

These sound like manageable things, plus you get all that extra storage, too.  Do you have room for an olympic size pool?

Do you think I am insane?  You bitches can go swim at Salmon Creek, if you want to swim. It's right across the street.  The water is beautiful and clear.

Nice looking home. For one with 2 big freaking garage doors in front. That isn't my fav. But our old house had that as the sidewalk "feature" so I guess it didn't bother me too much. I really like our rear access garage here in Bend

Wilbur is right about the spray foam. That will seal up tight. You can do a small amount of spray foam then over insulate with dense pack. UTFG for that. Spray foam gets very expensive in thick amounts. And in (R)oakridge I'd be worried about finding a qualified applicator. GBA is a good resource. Don't worry about getting too far into the weeds with them. They can count fairies on the head of a pin pretty well

I'd think about a small toilet/wash tub in the downstairs. Come in from muddy riding and be able to wash up a bit before going upstairs. Garage door openers come with drivers on the rails so you don't have the big unit hanging down. That transmit sound through the connection point 

http://www.centstome.com/side-mount-garage-door-opener_D31675/side-mount-garage-door-opener-i40-on-top-home-decoration-idea-with-side-mount-garage-door-opener/

Look at double stud construction for well insulated walls. This guy is a bit of a kook but knows what he is talking about. You are going to want to control moisture movement over on the wet side of the State.

And a mini split system for heating a small space like you are doing. I have seen 1 mini split do the area you have planned. But 2 is probably better. One in master bedroom and one out in the Great room. No big furnace. Which is now advised to be inside the building envelope. Which eats up SF

I like the layout for a small place.  I would enjoy the balcony.  As someone said, a small bath in the garage would be handy.  You could do it just opposite the water heater under the dining area.  You would need to take at least a few inches from both haves of the garage but that would be minimal.   I like the metal roof idea and yes you should consider both a quiet mount and quiet garage door openers - that's doable. We have a nice bed and bath space above our garage that Daughter#2 used for a while.  Her biggest complaint was the garage door openers.

Also, he seems to be analytical and does seem to understand home builds, or he portrays that.

Hi, Nate.

[Thaddeus Kosciuszko]

DH, from what you've posted of the lifestyle you're looking for this house seems a better fit than the previous model.

You've got a lot of good comments already: The climbing of stairs, the added insulation between the garage and the living spaces, the noise created by the garage door openers, the leaking of cold air around garage doors.  You may want to apply Scrapr's thought of double stud construction to the joists above the garages to create more sound and energy insulation.  It will cost you slightly more but you may even recover that cost in energy savings.

When you do talk to the architect, tell him you are concerned about establishing a full 'thermal break' between the garage and living spaces, and his details for the walls, the stairs, and the utilities going from the slab to the second floor need to show this or specifically call it out.

I would suggest reversing one of the floors so your bike storage/exercise space is below the bedrooms.  You will have less heat loss from garage door opening/closing from the car going in/out, and you won't have to worry about the noise/vibration because the active garage door opener will be on the other side of the house under the great room kitchen.

If you're going to use one side as storage/exercise and not for a car, I would suggest framing out the garage door opening but not installing the garage door.  Fill in the opening with siding and insulation just like the rest of wall to reduce heat loss.  You could put in windows for natural light, and this would make the house seem less like a garage with a cute house on top.  It will look more like a cute house with a garage instead.  And too, this way you save money on heat, but if you sell the place the next owners can easily open it up to get the car garage back. 

You may want to consider an in-floor heating system for the bike storage/exercise area if you will be using that frequently in winter.  You will have to spend more to get that, and more to insulate the ground beneath it, but it's a good system for heating slab on grade living spaces.  You will need a thermal break between the garage side and the exercise side if you do that.

Check that the kitchen will meet your expectations, as the layout and storage space seems limited and very compact.  It may very well be what you want, but the kitchen is set up so it's not easily expanded.  Expansion would take space away from the dining area or great room, and the kitchen intrusion into either of those areas will appear awkward.  You may also want to consider having the island put on wheels so when you're busy in the kitchen you can back it up to get a bit more room, or move it to become an extension of the counter.

If the kitchen isn't big enough, perhaps you could flip the kitchen and the dining area.  Put the bump out on the side wall instead of the back, make the kitchen bigger along the back wall and make the dining area a little smaller.  That way you could get a larger kitchen in the same square footage.  The disadvantage is you're walking up the stairs, entering the house directly into the kitchen.

With the kitchen, take the plan and draw in it all the appliance doors opened up.  That will tell you if/how the open doors will restrict your movement, which could lead you becoming quickly frustrated with your brand new kitchen if you feel the doors are constantly in your way. 

Having a sink in the first floor could be a good idea, but remember any dirt you wash off the bikes ends up on the floor inside the garage, and then you have to clean that up too and put the dirt outside.  If you wash the dirt down the drain then it 'disappears', but then that's not good for a septic system or good for a street connection to a municipal sewer system either.  You may want to relocate the small garage door from the side of the house to the back of the garage, and put a hose bib next to the door.  Then you could bring the bikes up to the back door, wash them off in the yard, the wheel them into the back garage door and directly into the storage area.

If you decide to heat with a furnace, put the furnace in the bike storage part of the garage.  It won't take up room on the second floor then, and the waste heat that comes off of the furnace will help heat that space.  You can construct a small non-structural closet to hide it from view if you like.  I would suggest putting it in line with the stairs so it's central to the second floor which may reduce your duct costs.  That will also protect it from damage from vehicles entering/leaving the garages.  You will have to spend a small amount more to better insulate the ducts running the garage space.

The water to the kitchen and the bathrooms will need to come up through the slab, through the garage, and run under the second floor deck to get to the kitchen and bathrooms.  Your contractor will need to take care that the water is run in such a way that it won't freeze, especially if you lose power and have to go on the generator, or if you accidentally leave the big garage door open on a freezing cold day.  My suggestion would be to run the water up through the center of the house, near where the stairs end on the second floor and not on any of the exterior walls, and enclose it in what's called a 'chase'.  The architect will know that that is.  Any water lines that run over the car garage you may want to wrap with insulation before you close the ceiling and floor up, even if you're going to heavily insulate the ceiling over the garage anyway.

Metal roofs are long lasting.  Make sure you get one with hidden fasteners, and not the kind where they use nails with rubber washers to keep the roof panels on, but I suspect you're well-informed about metal roofs anyway.

A generator may be a good idea for your area.  To save some money, you may want to put in what's called a manual transfer switch and a sub-panel.  A sub-panel connects only selected circuits in the house to the generator through the transfer switch. That way you don't run the whole house - only what you need - and you can buy a smaller generator that cost less to maintain and uses less fuel when you do use it.

Have the architect check your building codes regarding a garage below living spaces.  Most building codes require such garages to have fire-rated walls, usually one hour rated, around the garage.  If your codes don't require it, I would recommend spending the extra to get it.  The architect's plans should clearly state that all the walls and ceiling should be fire rated and should include a detail on how the contractor is to build it.

With that fire rating - and often ignored - is a technique called fire-stopping.  A fire rated wall does little good if someone punches a hole in it to run an electrical circuit or install a box.  Fire stopping is like a red putty that goes around the opening.  In a fire it expands and keeps the fire from traveling through the hole, past the fire rated wall and into the rest of the house.  All openings into and out of the garage where the car will be need to fire stopped. 

If you build a wall between the exercise space and the car garage, it will need to be fire rated on the car garage side and will need to be fire stopped for any penetrations too.  Check your codes because any door between the spaces will probably have to be fire rated as well, because the fire wall will do no good if the fire just burns through an ordinary unrated door.  A fire rated door will cost you more, but it could save the house if a fire starts in the car garage.

My apologies for the long post - I hope it wasn't too-long-didn't-read for you, and that is was helpful.  But please remember, you DID ask the engineer a question.
