Hi! Sam here, I am in freelance practice based here in West London UK, though I also have regular clients both in the US (Maryland), NSW Australia, and the Philippines. I specialise in home extensions, focusing on design and 3D visuals. I have a portfolio in my account showing my work especially with the projects we've done similar to the project requirements you have. I have experience in dealing with councils mostly in west London area - Ealing, Harrow, Brent, Watford, and Hillingdon. Though I have also dealt with other councils in other areas for some projects. I mostly deal with residential extensions involving Householder planning, Lawful Development certificates, and other permitted development applications for home extensions, involving preparation of planning drawings, submission to the appropriate planning authority, and liasing with the assigned case officer with back and forth communication, amenments if required, negotiation if we are trying to push a certain aspect of the submitted design.
I can send you samples of my work especially related and similar to the output you will need, pls do message me for me to send these to you.
Please do contact me if you are interested, proposed price is indicative and we would very much be open to discussing this later should you choose to go with us. Thank you.
