The example says it's a "same-size house" which I assume means the same numbet of bedrooms and bathrooms. A more modern design is a given, but I'm still perplexed by the notion a modern design might be expected to be so superior that a house squeezed onto a front lawn would be worth 15% more than a same-sized house in the same location with a front lawn, and a back lawn, and a whole double garage and driveway rather than maybe a share of it.
