Yay, glad to see you here also @suzes and @Sandraelle . Yes, I would prefer to go with smaller lots while keeping as much to scale as possible. Heading in game now to play around with a 4 width and will circle back.
Sandy, I'll be providing the 2 version of the exterior patterns for consistency and place windows and doors. However, based on your car and design, you can customize to delete / move / add more windows. For the exterior, it would also be more consistent if I provide the base landscaping (trees, platform, terrain paint) but everyone can add objects as desired.
