Room Additions with Zephyr Thomas

Zephyr Thomas handles room additions projects from A to Z. We deal with all of the hassles including obtaining your township’s permits and inspections. Think of it as bundling all aspects of your project into one, and forget all the worries of contracting separate companies to complete your one job. We have our own employees construct your foundation, build your room, and take care of any plumbing or electrical needs. Want wall to wall windows for a beautiful view of the outdoors? Or maybe slider windows with large patio doors for some interior wall space? Choose from dozens of options and let us help you with design ideas, or create your own personal vision of your room and we will take it from there! We can make your dreams a reality! If you’re interested in 4 season sunroom additions, check out our options!

An addition can offer a large amount of opportunity for storage, entertainment, and beauty in your home. Home additions can become space for:

  • A personal gym
  • Greenhouse/indoor garden
  • Spa room
  • Reading nook
  • In-home movie theatre/ TV room
  • Hobby or craft room
  • Children’s playroom
  • Rumpus room
  • Meditation room
  • Mudroom
  • Or anything else you can imagine!

4-Season Room Addition

I retired from NYC Government after 44 years of service this past June and relocated to Lancaster to be near my Grandchildren. We decided to add an additional room onto our home in passing on Harrisburg Pike came across the Zephyr Thomas Company. When we stopped in they had an amazing showroom, treated us like family and discussed our every need. Construction, product, electrical, heating, and air conditioning, cable run, windows, concrete, doors, township and state requirements, we spent some time and " what a reliable company". We talked about price and reliability of staff, proudly all skilled labor. There was no need for me to go elsewhere and boy what a wonderful job they did. They handled everything including dealing with my homeowners association. This company was spectacular in every respect. Great job guys and hope this is printed. You make me proud and your reliability, they were great.

- Arnold Pack

If you want the best workmanship and customer service use Zephyr Thomas because they are the BEST. They made the addition of my three seasons room an enjoyable and delightful experience. I will only be calling them for my future needs in any home improvement areas!!!!
