That will happen in the next 1-2 years, so, definitely before the addition if one were to happen.</p> <p>@hellobeeboston: @Mrs D: as for setbacks, I found out it has to be 3 ft from the fence. So maybe more like a 8 x 14 space I guess. </p> <p>@Ms. RV: Not sure about foundation? I think it could be simple. We don't have a basement, and we'd be converting xeriscaping to this room. We have some friends that has dyed and sealed their concrete in some room, and used throw rugs, and it looks really nice. </p> https://boards.hellobee.com/topic/costconsiderations-for-a-home-addition#post-2831009 Wed, 27 Jun 2018 18:02:27 +0000 Ms. RV 2831009@https://boards.hellobee.com/ <p>What kind of foundation will you need? If you can get away with a slab that will save a lot.</p> <p>Also, what about HVAC? Can you branch off of what you have or will it require an independent system?</p> <p> My mom had a similar addition done about twelve years ago (crawlspace foundation) and it was $20k. But she also has a $2.5k door to the outside in that addition. </p> https://boards.hellobee.com/topic/costconsiderations-for-a-home-addition#post-2830977 Wed, 27 Jun 2018 14:56:32 +0000 hellobeeboston 2830977@https://boards.hellobee.com/ <p>Anyway... It sounds like you know exactly what you want to do and it's pretty straight forward (so you won't need an architect probably, which will save you some $$).... </p> <p>I would also recommend getting some general contractors in to start quoting the project, you'll get a much better idea of the cost. It really varies by area. </p> <p>Not the same as a full addition, but my experience....We just tore down an existing deck, put up a big screened porch with an open deck to the side. We got a few quotes and they came in ranging from $18k - $65k!!!! It was CRAZY. we went middle of the road, but you will want to find the right person to work with who will do what you want. It was surprising how many GC's wanted to do things THEIR way and not our way.</p> <p>And yes to checking your setbacks.... we ended up having the building inspector make us get a service because we were *close to the side setback. Even though there was a structure there, since we were knocking down he considered it new build. Got the survey ($900) and it was fine, but set us back a month. </p> https://boards.hellobee.com/topic/costconsiderations-for-a-home-addition#post-2830976 Wed, 27 Jun 2018 14:50:32 +0000 hellobeeboston 2830976@https://boards.hellobee.com/ <p>oh man, i'm so mad. I just typed a whole response and hit submit and it vanished! :( </p> https://boards.hellobee.com/topic/costconsiderations-for-a-home-addition#post-2830821 Wed, 27 Jun 2018 05:48:36 +0000 Mrs D 2830821@https://boards.hellobee.com/ <p>We are going through some similar dilema with our house. We started seeking consultations from local GCs just last month. For us, we like you LOVE our current home and so much about it. All that we dont love would require structural changes. </p> <p>What I am learning is about $125/ft to add sq footage - its a good starting point. This would be builder grade finishes and no plumbing or crazy electrical. You also would have to consider if it makes your HVAC system incompatible with your future footprint. For example, we are currently at about 3k sq foot, if we do a 500 foot addition (most likely) we can still squeek by with single units, any larger and we need to consider the need for two units, especially AC.</p> <p>Also to consider is the set backs on your property. Will the city/association allow you to place the addition where you are looking to place it? There are restrictions with how close a structure can be to side yard lines. You should be able to find info to at least make an initial assessment online. For example, our side yard set backs are around 15'...we have 30' now, and only need to add 4' on that side, so we feel pretty confident we are fine proceeding in these initial steps!</p> <p>Lastly, have some people come out. The 3 GCs we have talked to all had WAY different ideas and thoughts. It always helps to solicit feedback from an expert. They also have been TOTALLY happy to come out for initial no commitment consultations.</p> <p>Let me know if you have any other questions! </p> https://boards.hellobee.com/topic/costconsiderations-for-a-home-addition#post-2830798 Tue, 26 Jun 2018 21:19:59 +0000 DesertDreams88 2830798@https://boards.hellobee.com/ <p>DH and I LOVE our home.... except it has 3 bedrooms, and we'd like 4 ultimately. The design is pretty standard (1 story, central hallway, bedrooms branching off) and there is only one place we could add a bedroom. It would be off the kitchen. Currently that wall is brick on the outside, drywall inside, with two windows. It would be a 10 x 14 space, or so. Anyone know the basic cost or things to consider for something like this? We wouldn't build the room for another 5-8 years, if we were to do it at all. </p>
