Deep River, Connecticut
Deep River Residence
A low modern house on a shelf of blasted ledge above the Connecticut River. Everything on it is exposed, which means nothing on it can be fixed later.
Hanby Lontine Architects designed it out of Kent. It is a single long bar in the woods — board-formed concrete below, stained wood and glass above, a flat roof drained by bent metal scuppers, and a courtyard cut into the middle of it. There is no trim in the conventional sense. Wall meets floor at a reveal. Ceilings run into slot diffusers painted black. The stair is painted flatstock with kerfs cut at a quarter and a half inch and no visible seams anywhere.
Detailing like that removes a builder's margin for error entirely. On a traditional house, casing and base cover the difference between the drawing and the framing. Here there is nothing to cover it with. Every plane has to be right when it's built.
The site had to be made before the house could be. It was ledge, and it came out by drill and blast — weeks of it — before a single footing could be poured.
Twenty-one field sketches came out of the architect over two years: the scupper, the slab step, the stair kerfs, the drainboard milled into the laundry counter, the house numbers, and a roof opening drawn around a tree. That is what a house with no trim asks for.
Making the Site
The House in the Woods
- Base
- Exposed architectural concrete, formed for finish
- Walls
- Stained wood rain screen, held 1¾″ off the sheathing
- Roof
- Flat, fully adhered EPDM, bent galvanized scuppers
- Reveals
- ¼″ and ½″ kerfs, no visible seams
- Air
- Linear slot diffusers, painted black, run into the ceiling plane
- Site
- Ledge, drilled and blasted before any footing
An opening for the tree
Sheet SK-02, issued March 2022, is titled opening for the tree. It draws a rectangular hole cut clean through the roof of the entry link, and a planter cut into the terrace directly below it, so that a Japanese maple can stand inside the house and grow out through the top of it.
It works only if the two openings agree. The roof curb, the beam it sits beside, the waterproofing that has to turn up all four sides, the planter walls, the drainage under them and the paving around them all had to be set out from the same centreline — on a flat EPDM roof, where a leak has nowhere to go.
Concrete You Walk Through
Concrete you intend to look at is a different material from concrete you intend to bury. Form layout, tie spacing, pour sequence and vibration all become finish decisions, and a cold joint in the wrong place is permanent. These treads were cast, not clad — there is no second chance on a stair like that.
