Other considerations and costs
- Taxes and permit fees are not included.
- Pre-fabricated kits may be available, however the exterior installation may require customizing that could negate the potential savings of a pre-fab kit.
DIY considerations
- This project requires a high level of carpentry skills, particularly in cutting the structural pieces to a possibly uneven terrain-landing situation, and furthermore joining many separate pieces and a handrail with attractive and secure results.
- Partial DIY is possible by taking on the minor concrete work.
