That hous is still extremely small for what most people in the US would put in a full sized suburban lot: Nowadays a median build is 2300 square feet (213 square meters). It makes that 1600 square feet look very small. The hallways, the large space dedicated to a great room and just 2 bedrooms won't help.
You will find new houses that small, but typically when it's extremely high value land, so typically infill. And then chances are it's a multi story house that fits the lot to the limit.
1600 square for two bed/two bath will feel large if well designed; many modern houses are not well designed for their size - usually one version of a given plan is the "optimal/designed" version, and you can keep adding things that make it frankly ridiculous, weird winding hallways, small rooms, etc.
Lindal has larger models, for those so inclined.
That said, the kit pictured will, if constructed, will have amenities & physical qualities that the similarly sized original Jacobs house has had to have retrofitted at great cost.
