3D Model of plans

Hi, I am developing a house and want to see how the plans will look in 3D but specifically I am thinking about making a change where the current porch is changed to a brick porch. This may affect the view from inside the living room as the porch will stick out of the front therefore i want to see a perspective looking out of the living room and study windows. That way I will have a better idea if the new brick porch will work and not block the view. I have attached the house plans (CAD not available) and I have attached an image of the new stone porch which should replace the current porch as shown in the plans. Additionally I have done a picture of the house with the new porch from the front view however this isnt good enough for me to understand what it would be like standing in the living room or study and looking out. you can use this to source stone and brick for rendering. To clarify the main purpose is to see the impact of the porch from left, right and internal perspective. Really need this ASAP. Good Luck.
