We are soon going to submit a building permit application for our upcoming garage. We plan to build it ourselves (stick-built) and base it on a construction drawing from Svenskt Trä - Byggbeskrivningar: http://www.byggbeskrivningar.se/garage#
The drawing of the garage we intend to build is 8.2 m x 4.6 m, but we would like to make the garage about 90 cm longer. Is there anything to consider when extending an existing drawing? Since we are keeping the width according to the drawing, load calculations, etc., should not change. Regarding the trusses, we'll need to add one more, see the drawing below for the placement of the trusses. As mentioned, are there any issues with extending the drawing?
