4289 Castle Avenue, Spring Hill, FL, 34609

Two houses in one! This unique single family home features a 3 bedroom, 2 bath home on one side and a full size 2 bedroom, 1.5 bath home on the other side with its own beautiful spacious kitchen. Welcome to 4289 Castle Ave. Located on a 15000+ square foot corner lot, in the heart of Spring Hill. Built in 1990. As you enter the home you are greeted by a formal dining room and billiard room. Moving forward is a big open living room and kitchen with custom wood cabinets, built in oven and plenty of counter space. The living room features a wood burning fireplace equipped with vents that blow the heat out into the room. This is Florida and you may only use it a few time a year. However, what you will take advantage of is the very large lanai with vinyl windows and a beautiful screened in, self cleaning swimming pool. You will also find in the lanai an air conditioned home office or additional room to use for whatever you choose. There are also three very large bedrooms and two full bathrooms. All bedroom have walk-in closets. Additionally, there is a huge laundry room with a ton of storage in-between the main home and the in-law suite/guest suite (Added 2006). Call it what you want but it is literally another home, designed fully AUD with it's own entrance from the side of the house. As you enter from either the outside or from the main home, you walk into a very large open kitchen/living room and half bath. Towards the back are two large bedrooms and full bath. The oversized two car garage features an electric vehicle charging station. A few updates worth mentioning for piece of mind are a new water heater was installed in the main home in 2025. Dual AC units installed in 2019, and a brand new roof will be installed on the entire home before closing and you can pick the color if you like. This home truly does have what's needed for multigenerational living or long term guests. This is a one of a kind and must see.
