Estate pools and indoor pool rooms
Gladwyne clients often want more than a pool: a spa, an automatic cover, a pavilion, and in many cases an indoor pool or Endless Pool for year-round use. Indoor water is a building-science project — vapor barriers, dehumidification sized to the water surface, corrosion-resistant fixtures, and drainage all get designed before framing, because retrofitting any of it means opening the room back up.
