No one not on site with you, vewing the structure, can tell you if you have a feasable plan or not. Only your local permits office can tell you if they will allow the addition, what written documentation they will require, and whether or not they will allow a homeowner to do the work. Bumpouts of existing spaces are just as expensive as larger additions, as the most expensive part is where the new ties into old. It will affect your roofing, siding, foundation, framing, windows, insulation, electrical, HVAC, and possibly plumbing. None of that will be cheap, even with ''free' labor. And it is not likely to be recouped in additional value to the home. Also plan a talk with a real estate agent about your plans, and their impact on the resalability of the home.

Hi, I still would like to hear from anyone who has done or knows anything about this kind of roof extension remodel, that is adding three to six feet to the front of a house by simply continuing the existing roof line down and out and building underneath it. The existing front wall would be removed and replaced with a double set of heavy lvl beams supported on end by posts or perpendicular interior walls, with the load transferred to the existing 12 inch cement block wall and 20 inch concrete footing. The new ceiling and roof would be stick framed with 2x4's and 2x6's , tying the ends of the existing roof trusses and the sides of the new lvl beams to the new outer wall. I'd build a new 2x6 framed front wall on a new poured footing and block wall up to grade.

I believe I can figure out all the construction except the lateral stability of the new ceiling and roof section. I'm concerned because the top of the new front wall would be 2 to 3 feet lower than the bottom of the heels of the existing roofing trusses, and I am not sure what kind of lateral forces would act on this structure.

As for aesthetics I believe an extended sloped front roof would probably look better than 3 high cross gables that start at 16 feet over the driveway and 12 feet over the front steps, that may look too high. I also do not want to cut back two large trees that overhang the front of the house, including a 200 year old burr oak.

On the inside the sloped front ceiling is far from ideal but still acceptable, as I would still have a 9 1/2 foot high ceiling in the foyer, 6 foot ceiling in the living room and 5 ' 8" ceiling in the bedrooms. I recently saw a 2 million dollar new construction home in Edina Minnesota with 5' 8" sloped bedroom ceiling that looked great. With smaller rooms with windows that look down into a yard lowered windows can work.

I understand no one without seeing my precise plans can tell if they are doable, but I would like information in general if something like I propose could be done. I bought this foreclosure home two years ago, and since have peppered the city building officials with so many questions that I thought I would try to seek more information from others before I talk to them again.

Hire a local structural engineer. It sounds as though it would not make for a very livable or attractive structure, so as an expenditure, it would cost you a lot, and be a wasted expense.

Can it be done? Sure.

Extending roof lines is not uncommon.

To get this permitted, your permitting office will likely require your plans be stamped by a structural engineer. The idea is to draw up what you want to build. With your proposal, an office visit to an engineer would be a good thing to get things started. Some will want to work with you off of your drawings. Some may not. Some might want a visit to your house. Some may not.

The engineer will typically figure how the loads are transferred through the structure from roof line to footings and indicate the specs for beams, connectors, etc.

Loads, shear, uplift, snow...all those will be taken into consideration.

You do need to be careful since you have trusses. Anytime an engineered system is modified (a truss is cut for example) the alteration should be an engineered solution.

Good luck!

Additionally, do you have room on your property to do the addition and still be within setbacks?

Your permitting office will walk you through this.
