Building notification and calculation glulam beam

[grongolingen]

Hi,

I have read this forum many times and today I took the step to become a member
My wife and I will soon take possession of our first house (single-family 64 sqm) in Tallkrogen and are planning to do quite a bit of renovation.

The first project we plan to undertake is the renovation of the kitchen and at the same time opening up between the kitchen and the living room, where we have the heart wall according to the plan.

The opening we would like to make is 216cm and can be seen on the attached drawing, and we would like to support this with a glued laminated beam or steel depending on the recommendation.

My questions to you knowledgeable people on the forum:
1. What would you recommend to support this with and why? What dimensions?
2. Could I make an approved building application myself with the help of Moelven's program (or equivalent) or is a professional needed? Any tips on a structural engineer in Stockholm?

Thankful for all the help I can get!

Have a nice weekend!

It is a relatively short span, and the girder only needs to support the attic and parts of the roof, so, for instance, glulam is a good option here. Glulam is also easier to work with than, for example, steel. What function does the attic have, do you access it via a hatch? Depending on function and accessibility, the standard indicates different loads.
It might be possible to do the building notification yourself, depending on what the municipality says. It is important that you can refer to the correct standards and loads and perhaps a calculation. The app is somewhat of a closed box and shows nothing about how the beam is calculated, etc. I also don't think the app can handle your case since parts of the roof rest on the wall.
You could absolutely handle it yourself, but it's always nice to have someone else take responsibility if you aren't completely sure yourself.

Hi! Thanks for the quick response!
The attic will primarily not be used for anything. It is only accessible via a hatch from the outside.

I get completely confused by those calculation programs, I'll have to find someone knowledgeable.

The small residential homes in Tallkrogen have lasted for over 60 years. Making your little change will strengthen the house almost no matter what you do. Is the chimney a divider of the heart wall, or does it span a long beam through the entire length of the house that holds the gables together? If it's a long beam, it should be supported, talk to a structural engineer if you're unsure. If it's a short heart wall, it probably holds the gable of the house, so again, speak with a structural engineer.

But take it easy, this is an operation many have done in their own homes, just contact the right people, and it will be a piece of cake.

Tallkrogen's small egnahem have lasted for over 60 years. Making your small change will make the house stronger no matter what you do. Is the chimney a divider of the heart wall or does it have a long beam running through the entire length of the house that holds the gables together? If it is a long beam, make sure to support it, talk to a building engineer if you are unsure. If it is a short heart wall, it probably holds the gable of the house, so again, talk to a building engineer.

But take it easy, this is an operation that many have done in their egnahem, just contact the right people and this will go smoothly.

Thanks for the response! Many good questions that I'm not aware of, but I'll chase the right people next week.
