Protecting Your Watercraft Investment

If you own waterfront property on Lake Coeur d'Alene, Hayden Lake, or another North Idaho lake, a boathouse is more than a luxury—it's protection for your significant watercraft investment.

At Peterson Construction, we build custom [boathouses](/services/boathouse-construction) that combine functionality with stunning design.

Why Build a Boathouse?

Protection from Elements

**Sun damage**: UV rays fade upholstery and damage fiberglass

**Weather**: Hail, wind-blown debris, and heavy rain take their toll

**Winter**: Covered storage protects from snow and ice

Security

A boathouse with lockable doors protects against theft and vandalism.

Convenience

Boat is always ready to launch

No trailering required

Storage for water toys, gear, and equipment

Property Value

A quality boathouse significantly increases waterfront property value.
