Boat House

Photography by Benjamin Benschneider.

A waterfront accessory structure that replaced a dilapidated boat storage shed. 

The genesis of this project was a failing retaining wall at the base of a 1970's waterfront house built on a steep slope.  The boat house had to be removed for the replacement of the wall so clients asked that the boat house be replaced with a new structure containing additional living space.

Water access was not possible because of the shallow water and existing docks so access to the site was limited to a stairway alongside the existing house.  All materials had to be hand-carried down the stairs.

The project was further complicated by a utility easement on the water-side that limited the footprint of the structure as well as soil conditions that mandated pipe piles to support the retaining wall and structure.

The solution is a two story-volume that wraps over the retaining wall providing an entry on the upper floor. A second-story balcony is hung on the side of the structure and can be removed if access to the buried utilities is required.

The project includes a PV array on the roof of the existing house and a PV array on the roof of the boat hoist on the dock.  The structure has a green roof and a rain-screen exterior.  Heating is provided by a gas-fired boiler providing hydronic heating.

The general contractor was Toepfer General Contractors.
