House Building in Dunwoody, GA

The frame is the part of a new house most people forget once the drywall is up, yet it decides how solid the floors feel, how straight the walls look and whether the roof stays true for decades. In a house building project in Dunwoody, a good share of the planning goes into framing and the building envelope that wraps it.

The floor plan, the finishes and the order of work all rest on that structure.

Floor systems, walls and roof framing

Floors in new homes are often built with engineered I-joists or open-web floor trusses rather than solid lumber. Both span farther and stay flatter, and open-web trusses leave room for ducts and pipes to pass through without cutting. Walls are framed from studs, with headers over openings sized for the loads above. Roofs use either factory-built trusses, which go up quickly and are engineered for the specific design, or site-framed rafters, which allow vaulted ceilings and attic rooms.

The interior layout should be settled before the framing drawings are final. A room that grows by two feet can change joist spans, beam sizes and roof framing, and the work sequence assumes the layout will not move once walls stand.

Wrapping the frame: the building envelope

Once sheathing is on, envelope work begins. A weather-resistive barrier covers the walls, lapped so water runs down and out. Windows and doors are flashed into that barrier, with sill pans or flashing that sends any water back outside. The roof gets underlayment and its covering, with flashing at walls, chimneys and valleys. When those steps are complete, the house is dried in, and interior work can proceed with far less risk of water damage.

Structural reviews, long-lead orders and site access

Before pricing, three items get a close look. The drawings should show beams, posts, hold-downs and point loads clearly enough that the framer is not guessing. Trusses, windows, exterior doors and custom cabinets are listed with their order deadlines, since all of them take time to arrive. And the route onto the lot is checked so truss deliveries, which can come on long trailers, and other materials can reach the house and be lifted into place.

Choosing floors with the plan dimensions in mind

Flooring selection affects work long before installation. The stair rise, door heights and cabinet toe kicks shown on the plans are set around a finished floor height, so changing from carpet to thick tile can leave a short step at the top of a stair. Openings in the floor matter too, since a floor register, a floor outlet or an island gas line has to be placed precisely before the subfloor or slab is finished. Choosing floors early lets the frame and subfloor be built for them.

Fixtures, exterior cladding and windows

Lighting and plumbing fixtures, exterior materials and the window and door package make up the remaining big selections. Fixture choices set rough-in heights and box positions. Siding, brick or stone determine trim depth and how windows are flashed and finished outside. Window style and size shape both the facade and the light indoors. Some families find that a well-framed room addition in Dunwoody solves their space problem without a new house.

Before the final walk-through, the site deserves its own review: final grading sloping away from the foundation, downspouts discharging clear of the house, and site planning items such as walkways and the driveway finished as drawn.

Dunwoody inspections and owner permits

Dunwoody is in DeKalb County, and permits run through Permits & Inspections in Community Development. The city’s code calls for an underground plumbing inspection after the trench is dug and the pipe is laid, before any backfill goes in.

According to the city’s permits and inspections FAQs, the city issues permits to owners only if they hold a contractor’s license or occupy the home being altered, and it does not accept photos in place of inspections.

Questions about framing, inspections and dry-in

What is the difference between roof trusses and rafters?

Trusses are engineered and built in a factory for the specific roof, then set in place on site. They go up quickly and span long distances. Rafters are cut and assembled on site, which allows vaulted ceilings or usable attic space but takes more labor. The roof design and the rooms below usually decide which makes sense.

Can photos replace a plumbing inspection on a Dunwoody project?

No. The city states that it does not accept photos in place of inspections. Its code also calls for an underground plumbing inspection after the trench is dug and the pipe is laid, before any backfill, so the trench has to stay open until that inspection has been completed.

What does it mean when a new house is dried in?

The roof covering, wall weather barrier, windows and exterior doors are installed and flashed, so rain no longer reaches the interior framing. It is an important milestone because insulation, drywall and other interior work can then go ahead without exposing materials to water. Drying in normally follows framing closely.
