Even in the US with larger houses (outside cities anyway), few people have an entire room to dedicate to a home office, much less two. We repurpose attics, garages, large closets, guest rooms, etc. If a couple wants two dedicated permanent office rooms, it doesn't make sense to stay in an urban center. It might make sense to rent external office space (perhaps to share with others), or stay cramped and consider it part of the tradeoff of not having to commute.
