Custom Pool Builder on the Main Line
Main Line pools are often placed into sloped, wooded lots where grading, drainage and tree protection decide the location. Endless Pools also fit well in lower levels and pool rooms in larger stone homes. We handle the drawings, the local permits and the build, and price your project at a free on-site walkthrough.
Build your estimatePools for Main Line homes
Main Line homes are often 1900s–1940s stone colonials, Tudors and estates with plaster walls and deep stone foundations.
- Pool location set after grading and tree review, not before.
- Indoor Endless Pool rooms planned with ventilation and moisture control for older houses.
What affects projects on the Main Line
- Several Main Line neighborhoods fall under historic review, which can add a design approval step before the building permit.
- Mature trees and steep lots often bring tree protection and grading review into the plan.
Additions that read as original
Main Line architecture is unforgiving — Tudor half-timbering, Colonial Revival cornices, Wissahickon schist, slate roofs, and true divided-light windows. A new wing that misses the brick coursing, the mortar color, or the roof pitch announces itself forever. We source matching stone and millwork, replicate trim profiles, and detail the transition so the addition is invisible from the street.
Permits & local rules on the Main Line
Plans are reviewed by the Lower Merion, Radnor or Tredyffrin code office, depending on your address. We file and track every permit for you.
- Step 1. Zoning review: setbacks, lot coverage and height limits set by the Main Line's local zoning rules.
- Step 2. Building permit filed with the township or borough code office serving the Main Line (Pennsylvania Uniform Construction Code), using our in-house drawings.
- Step 3. Pool permit with barrier and fencing requirements, including self-closing gates.
- Step 4. Electrical permit and bonding inspection for pumps, heaters and lighting.
- Step 5. Stormwater and setback review for the pool and surrounding patio.
Exact requirements depend on your property. We confirm them with the local office at your walkthrough.
