After a pleasure flight departing ZZZ; upon our return; we were unable to lower the landing gear for a 'land' landing. After a number of attempts to cycle the circuit breaker and the landing gear switch; I made the decision that the safest course of action was to set the plane down on the fuselage in the grass to the east of Runway 36 at ZZZ. The landing was uneventful and we slid to a stop in about 200 ft. No injuries occurred on either occupant and no damage occurred to the plane as the fuselage is a water hull and lands quite smoothly on the keel. We brought out several floor jacks; lifted the plane; pushed the gear down manually and engaged the down locks. We taxied the plane back to the hangar after the occurrence.
GA pilot reported the failure of the landing gear to extend; resulting in gear up landing on the grass surface adjacent to the runway.
