Start with a simple pencil sketch of the lot with the home floor plan. Compile photos of rooms that you like using an Ideabook here on Houzz to share with design professionals. Research architects to find a good match to fit your needs. Architects have the incite to help you select the construction professional that should also be a good match. Plan, plan and then plan more! Changes during construction are usually costly. Hope this helps! ClearLED.biz

Hi abin30310. It's great to hear your passion for natural daylighting and ventilation. We worked with a client years ago who shared this passion, check out the home here: EB1 Residence - RHO Architects. The privacy aspect could be tackled via frosted glass, high windows, etc. These solutions will bring in daylight while providing adequate privacy. Hope this helps!

Dear Vijay, Its alright if you are clueless of what to do. What are architects for? But you need to take a right approach. Mention your details and requirement in efficient way. Few to mention- Location Kind of work- architecture or interior? Plot size/built-up area. Layout of the site/floor plans(if interior) Orientation Services you are looking for- just ideas/floor plans/3d/working drawings etc. Few images of site/house(if interior) Houzz is good and full of many talented people. This way things would be easy for professional to respond. Hope this will help you a bit to imagine what you are looking for. Thanks and Regards
