The finished home after the four-room addition and redesign, with white siding, black trim and a rust-toned accent wall

Project case study

Four rooms added, the whole house redesigned

Four new rooms and a redesigned exterior on an existing home, photographed stage by stage: the original house, the framing, the sheathed envelope, the weather barrier, and the finished exterior.

About this addition

This project added four rooms to an existing home and redesigned the house around them. The new rooflines, the tall siding and the rust accent wall give the finished house a different shape from the one we started with. The tall front is a facade that changes how the house looks. It is not an extra storey.

An addition like this lives or dies on the connection between old and new: the structural tie-in, the roofline, and making sure the finished result reads as one house rather than two. The photographs below run in the order the work happened, taken on site rather than staged for the site.

This is the kind of work covered under additions and extensions generally: matched rooflines and finishes, with the structural work engineered properly.

Stage by stage

How the addition went up

Five stages, in order. Select any photo to view it full size.

1. Before

Stage 1 of 5

The original home, with brick on the front, before any work began.

2. Framing

Stage 2 of 5

Framing for the added rooms going up beside the existing house. This is the stage that sets the new footprint and ties the addition structurally into the home.

3. Roof & envelope

Stage 3 of 5

Roof trusses set and walls sheathed in OSB. The new roofline and tall front walls are visible for the first time.

4. Weather barrier

Stage 4 of 5

Wrapped in housewrap and ready for cladding, with the old brick coming off the front in preparation for the new exterior. Getting the building wrapped promptly protects the framing while the exterior finish is planned and ordered.

5. Complete

Stage 5 of 5

The finished home: white siding top to bottom, black trim and windows, and a rust-toned vertical accent at the gable end carried down beside the garage.
