Two Separate Bedrooms
A double master bedroom plus a second bedroom that works well for guests, grandchildren, or a live-in carer. Both have space for wardrobes and furniture.

Built for Flexibility
The second bedroom is useful in more ways than you might expect. Here are the most common uses we see.
Room for Visiting Family
Grandchildren can stay over, adult children can visit for weekends. The second bedroom means guests have their own space rather than sleeping on the sofa.
Live-In Carer
If care needs increase, the second bedroom gives a live-in carer their own room. This typically costs a fraction of what residential care charges per year.
Home Office or Hobby Room
The second bedroom works well as a home office or hobby room. Useful for couples where one person still works or has interests that need a dedicated space.
Shared Living
Suits siblings or other family members who want to live together but need their own bedrooms. Each person gets a private room while sharing the living and kitchen areas.
