Hello, check your design, I understand much of it, but it is necessary to incorporate a lot of information to have a better reading of all the spaces, also in this file that passed does not correctly represent the plant according to the drawing regulations, I can do the work that They request in an efficient way and at the lowest cost for you, but we have to define what is the scope, when you say that the engineer and for the permits need architectural drawings, do they refer to which products? I can make all these drawings and any other that is necessary and I can also advise them regarding the design that they are proposing, if it can be improved or better used, find the solution they want for the porch, I also offer them to make the three-dimensional model of the design, This can be done simultaneously in my studio between 2 architects who have a similar profile (20-21 years of experience) and we handle CAD and 3D modeling tools, I offer all this at the minimum amount set by you (freelance does not allow me to put a lesser amount) and we can provide this service over a period of 1 month, which I believe is sufficient to do everything (of course, the plans required before will be published in less time when required). I ask you to choose me, I have no recommendations on the page because I am taking up this profile after years of creating it without using it, but we have the experience and good references of our work (https://www.freelancer.es/u/bordonesm) I await your conta
