Hi, I want to convert our front porch(a concrete slab with a roof above and iron railings on 4 sides) to an enclosed 4 season mudroom. Also, I would like to extend the space by 1 ft on the front side. Where do I start. Do I need to hire an architect? Still in planning and budget estimation phase. I wouldn't want to include the cabinets for cost estimation. Wondering if someone can help please
You usually are not allowed to just use an existing porch pad and a roof for an addition. Roof has to have proper pilings for posts/beam support etc., and walls have to be supported as per code. Everything depends on your local codes for pilings etc. (here in Edmonton we have to go 8ft min.) They typically prefer to see "footing walls" for additions with pilings under them. A 4 season structure is considered a building addition. Yes, you will have to have it "engineered 1st and a detailed plan to apply for a building permit. If you are adding heat and electrical, that must also be in the plans and will require permits. Depending on where you live your local zoning authority may also require a development permit so check with them 1st. If you are able to go in person to your local planning & development that is 1st step to get the required info. They may even advise you on what you are allowed. In my experience most porch structures will not meet min codes to be adapted for what you propose and you will be looking at a teardown and the rebuild as proper addition.
Thanks John for these details
