Project Description:

Goals:

  1. Demo existing patio deck.

  4. Implement 4-8-4 cascading stair system and landing pad from main deck to ground level.
  5. Implement 27' long custom flower box array.
  6. Attach decking with hidden fastener system.
  7. Implement low voltage LED lighting system on posts, stair risers and flower boxes.

MLC Assessment:

  1. Existing house structure is in good condition for the project.
  2. Locations of existing underground utilities and ledge pose a design challenge.
  3. Existing balcony frame and drainage system needs rework.
  4. Balcony stair stringers in advanced state of decay and need to be replaced.
  5. Existing furnace intakes/exhausts, dryer vent do not meet code and need to be relocated.
  6. Irrigation plumbing needs to be relocated.
