Different Home Additions Cost In Villanova, PA

The Cost Of A Bump-Out Addition

According to HomeAdvisor, the expenses associated with expanding a room can vary from $85 to $210 per square foot. This estimate encompasses the construction of the foundation, reinforcement of walls, installation of new roofing material, and completion of all required finishing work.

Bump-outs offer a fantastic opportunity to enhance the appearance and functionality of your home. They are particularly effective in creating practical spaces like kitchens and breakfast nooks, while also adding a touch of elegance to smaller areas such as master bedroom dressing rooms. 

With bump-outs, you can elevate both the style and usability of your living space. According to Manta, a bump-out addition in Villanova, PA, in 2023 will cost around $57,500.

The Cost Of A Deck Addition

Adding a deck is a fantastic investment. It’s a cost-effective solution that’s about $20 to $50 per square foot.

For a luxurious outdoor space, we suggest opting for composite or hardwood materials rather than the commonly used pressure-treated wood, cedar, or redwood. Notable composite decking brands like Trex and TimberTech offer excellent options.

A small wooden deck usually costs around $10,000. However, a larger composite deck consisting of two levels, premier railings, and lighting can cost up to $50,000.

The Cost Of A Walk-Out Basement Addition

Constructing a walk-out basement can present challenges and incur significant costs. The more budget-friendly route starts at $20,000, while more lavish renovations can reach up to $50,000.

Usually, the market value of a finished basement amounts to about 50%-60% of the value of the main level area. When it comes time to sell, for every dollar you’ve invested in a finished basement, you can expect to recoup $0.79. While it may not be the most lucrative endeavor, it still commands a level of respect.

Although walk-out basements require a sloped terrain, it is not a common feature in Villanova, PA. As an alternative, walk-up basements can be considered as a viable option for expanding a home.
