The porch's highest point cannot be more than three metres high. We propose that a porch be no less than two square metres in size to make a construction useful with ample extra room. As a result, the best size for a porch that does not require planning approval is between two and three square metres. Larger porches may be constructed with a flat roof which reduces the amount of space they take up.
Planning permission is required for buildings that are used as dwellings. If you want to create a porch that will only be used occasionally, like as a garden storey or barbecue area, then it does not need to be approved by planners. However, local building regulations may still apply so check with your local council if you have any doubts about what types of materials should be used in construction.
A realistic porch size recommendation is adequate space for visitors or family members to share space securely with a door arcing 30 to 36 inches, resulting in a porch with an estimated minimum depth of 6 feet. Adding furniture implies making more room. A porch with furnishings should have a depth of 8 to 10 feet.
The majority of homes in the United States were built after 1990, so most backyards are not big enough for a proper porch. If you want to give your home a facelift and add value, a porch is a perfect idea. The modern-day porch should be functional and attractive. It should also provide privacy, protection from weather conditions, etc.
By far, the two most common types of porches are the flat roof porch and the gable roof porch. The flat roof porch is easy to build and comes in a wide variety of styles. It is suitable for all climates and can be either open or enclosed. An advantage of this type of porch is that it does not require any structural support and can be made out of wood, aluminum, or vinyl. Disadvantages include lack of insulation and limited visibility because of its flat roof design.
Gable roof porches are usually only available as custom-built homes because they require significant structural work to ensure they are safe for people to sit on. They come in a wide variety of styles and can be used for outdoor dining, sitting areas, etc.
Building a ground-level porch with a floor size of less than 30 square meters is usually free from the need for building regulation permission. The front entry door between the current home and the new porch must stay in situ for a porch to be excluded from building standards approval. If the porch will not be used as an entrance, then it can be removed from building regulations compliance.
Building a ground-level porch with a floor area greater than 30 square meters requires planning permission. There are some exceptions where this would not be the case but the general rule is that you will need to check with your local council if a porch falls within its boundaries. Porches that are attached to a house through concrete or steel supports will not require planning permission provided they do not exceed 3 metres high. However, any external features such as windows or doors must be retained during construction and should be rated by a qualified person.
It is important to note that most local councils require you to notify them of your intention to build a porch. This may be done via a notification order or an application form. You should check with your local council to see what requirements, if any, there are for building a porch.
Start with a 9-ft. Post and alter as needed to meet the overall composition of the elevation of the home. Avoid poles that are less than 8 feet, which will make the porch feel too low, or taller than 10 feet, which will make the porch feel uncontained. Piers should be located so they reach the middle of the floor joists.
The height of a porch post depends on how high you want the porch to come. Generally, the higher it is, the more spacious it feels. Posts can be as tall as you need them to be; just keep in mind that if you need extra headroom, you'll have to install additional posts. Posts on a porch should be sturdy enough to support whatever you put on it, but not so big that they're a pain to deal with. They should also be close together enough that you don't get gaps between them due to tree roots or some other reason.
As for diameter, that all depends on your taste and what you plan to use the post for. A porch post does not need to be thick; 1× lumber is sufficient for most applications. However, if you want the post to look good and add to the character of your home, then choose a wood that fits with the rest of your house instead of using treated pine or fir.
