Structural engineer needed please.

I have a garage project I'm wanting to do next summer.

I want to add a second floor in the garage for storage and occasional office.

I need calculations for I beam and timber joist sizes.

Can anyone help.

It's away from houses and not noticeable from road so I need figures for safety not documents for building control.

Garage is singe skin.

Length 6.8 meters
Width 4.8 m
Roof pitch will need to be 40 degrees
I want to put a 4m dorma on one side
Roof height will be 2.1m
Tiled roof

A cost for calls would be helpful.

Front wall is 2 skin on a I beam 203x133 over garage door.

Thanks.

Unless you built the original garage a good place to start would be to expose the foundations, this will give an indication of what you can build on top ?...

I did the footings when I built the garage and its on 600 x 1m deep.

So probably better than my house I bet :-)

Beautifully over engineered , they should be good for a skyscraper ...... Hopefully a structural engineer will be a long shortly, good luck with the project and keep us posted

Depends on the makeup of the ground, and what plants are nearby.

We looked at an extension, and dug a 1m x 1m x 1m inspection hole in our mostly clay garden. The building control officer came round with his little chart, and said that we needed to go to 3m, just because there are (the councils) hawthorn bushes surrounding the perimeter which apparently dry the ground out. The additional cost of the footings would exceed the benefit for such a small extension, and we wouldn't get it back in value on the property before were planning to move again.

What are your neighbours like? Permitted development rights only allow for a single storey structure.......

No one can see it due to 10 ft conifers and where the garage is.

Footings are as per structural engineer requirements.
