Framing - Near Completion

We're getting close to finishing up the framing. All the interior walls are in place, which makes moving through the second floor pretty exciting. Rough in for the electrical and HVAC is ongoing. There are a few framing issues to deal with to make space for the larger air ducts from the new second floor furnace. We're all doing our best to integrate everything seamlessly.

The roof is now complete and water tight with new asphalt shingles. Sun tunnels were installed in the roof for the closet, shower and hallway and will provide a generous amount of natural light in those areas.

Ceiling framing is complete in the bedroom. We decided to furr the ceiling down 5 1/2" from 9'-6" to allow a bit more flat surface area. This gives the recessed lights more room to spread out and catch the corners.


The stairs have been widened and lengthened to meet code, but also to provide more room for frequent trips up and down. The existing kitchen has been demolished and all cabinetry has been removed. All the new cabinetry has been approved so hopefully within a few weeks the installation will begin!













Framing - Roof Tie In

Today we had a site visit from our structural engineer, Eric Bunkers of Mattson Macdonald & Young. He was on site to review the construction so far as well as provide some new insight on how to tie in the new roof with the existing. Ultimately, it was decided that the last girder truss would move back from the original position and the tie in would be hand framed as planned. This helps to maintain the existing roof slopes and minimizes the view of the addition from the street.


The bonus room above the garage is completely framed in and all trusses are set for both dormers. We revised the headers underneath the dormers to 3- 2x4's in order to keep the window head height consistant throughout. This way we'll be able to get a desk or storage under each window sill.





Skylight openings were cut into the roof trusses during fabrication. Once skylights are on site, then the rough opening will be framed and they will be set in place.

Framing - Trusses & Second Floor

The prefabricated roof trusses have been set on the new 8'-0" second floor walls. All the rough openings have been measured and framed for exterior windows. The skylight in the bathroom was considered when manufacturing the truss design so only the rough opening will have to be adjusted.

The existing roof is still mostly intact, but will be removed once the framing and sheathing is in place.

Framing - Trusses & Floor Joists

The garage roof trusses have arrived and been set. Aligning the new fascia board with the existing has been the driving detail behind the height of the garage trusses and bonus room walls. Making these align required careful attention to the existing conditions and how they match up with the bonus room above the garage.




Framing - First Floor & Garage

The foundation walls have been back filled and framing of the first floor and garage has begun.








Foundation Walls

Excavation has begun and the footings have been poured! The garage and back porch were carefully removed to allow access to the existing foundation wall and footings. Originally, our footings were designed to be placed 4'-0" below ground. Given the soil type on the site and throughout the area, footing were revised to a dimension of 30"W x 10"D and placed at 7'-0" below grade. Two positive results came of the situation: 1. New footings tie-in at the existing, which allows for the existing basement to be expanded. 2. The footings are extremely stable! We could probably build a small high rise on these walls.

Demolition

Demolition began pretty quietly by taking down the existing fence and pergola. Snow was moved out to make room for the heating blankets.
