4 Answers. Is it possible the builder thought you meant a cantilevered deck - that could run to $100/SF or more - but still rarely the $214/SF he gave you, which would in most parts of the country build an entirely new addition with that square footage with basement and roof and all - fully interior finished.
The Natural Frequency Calculator which is a free service uses geometric and material variables and when applied on this project it was found that the Natural Frequency of the balcony constructions was comfortably above the recommended limit frequencies.
If you are adding onto a deck, you must make sure the footings are large enough to support the added loads. Balconies are defined as small decks built without support posts usually constructed with projected joists that are run back into the house. This type of deck uses sistered joist to project a cantilevered effect.
architect1281 - this is a post- and ledger-supported deck replacing a cantilevered balcony. Poking around a bit I see I have typical house rim joist on both sides of the cantilevers. The cantilevers are sistered to the inside floor joists about 60".
Cantilever limits by: VAIL8150 As a structural engineer I have been asked to do this many times and can only refer you to the IBC/IRC for flooring construction which limits an extension to cantilever balcony to 4' 6" using southern pine 2x12's on 123 OC. Also that must take into consideration the addition of double trimmers on sides and ends.
Cantilevering is a deck construction technique that can be used by do-it-yourselfers on almost all decks. It allows the builder to add several feet to the width of the deck without increasing the maximum span rating for the beams or the joists.
A balcony can be a delightful feature to add to your home but ensuring it complements the rest of the house is crucial, says Clive Fewins. Not every self-builder can run to the expense of the balcony on a new 300m² contemporary-style self-build house in Gloucestershire, where the cantilevered structure is 15 metres long, curved, and
Cantilever For Existing Deck by: Editor - Rich Bergman How far one can cantilever a deck from an existing supporting beam is a common question. The question arises when people decide they want to extend the length of their deck. Certainly it is easier to just add longer joists rather than move an existing supporting beam and post structure.
Use this calculator to find out the beam span and deck footing size for your project. Be sure to have your joist span calculations ready to enter for an accurate reading and check out our concrete calculator to determine the size of your footings. Total Linear Feet Of Railing
When a load sits on a cantilevered beam, two reactions occur at its support. There is the vertical shear force, which counteracts the object's weight, but the greater force is often the bending moment, which keeps the beam from rotating. You can calculate these loads using a couple equations.

Planning advice:how to add a balcony to your home without . A cantilevered balcony measuring, say, one-and-a-half metres by 1.2 metres is likely to cost you between £3,000 and £3,800. You should certainly be able to recover that when you sell.
Do not count only on the calculator, so it is worth finding 5-10 sites that sell tools and parts for deck. How much does it cost to create a cantilevered deck design. A DIY deck project costs $ 10 to $ 25 per square foot. The price depends on the selected materials, as well as on the complexity of cantilevered deck design.
The replacement process will depend on the design calculations. You may have to add new floor joists at the level of the deck. IF that can be done, you might jack up the old deck ever so slightly, add and secure the new floor joists, THEN remove the old vertical supports and put the weight of the deck on the new floor joists.

Costs vary wildly because costs vary according to homeowners' desires, locality, and a host of other factors. Some anecdotal price reports: $17,000: 2 feet by 10 feet bump out. $30,000: Bump out twice that size 4 feet by 10 feet $30,000: 6.5 feet by 28 feet bump out for a bathroom, on the ground, poured foundation.
Various calculation methods are available to assess concrete cantilever balcony. This projected through but the high cost
We also cantilever the joist to follow the profile of the pool but have never needed a 4 foot cantilever because we are closer to the pool. If the deck is wider and the pool smaller we use a V shaped beam near the pool where there are three posts and the middle post has beams resting on it at different angles to form a V shape near the pool.
