First time user of the forum...I will be installing hardwoods in our main level (1100 sqft) in a few weeks. My question is regarding layout of the planks. The Entry way is a long narrow hall (4' x 15'), at the ens there is a kitchen to the right and family room to the left creating a 'T' transition. Wondering if cahnging the orientation of the planks so that the floor runs longitudinally in all areas would be OK or if there was a better way to lay the flooring.

Any help is appreciated.

Your floor joists/trusses are going to dictate the direction of the flooring, unless you add more plywood or block between the joists from below to add more strength.

The subfloor is two layers of 5/8" plywood so hopefully that will be enough support. Still wondering how it would look if the direction of planks cahnged 90 degrees at the open entrances to the rooms. thanks

1 1/4 in. of plywood subfloor is certainly enough to nail to. I would check for ridgidness of the floor system: what are the joists 2x8- 2x10 obviously the bigger the joist the more ridgid the floor will be and you would also want to consider the spacing of these joists and the support underneath (girder placement) before deciding.Bridging or blocking can be utilized for strenght as well. I change direction of the flooring to allow for patterns and such on occasion. Check your floor and be honest with yourself before making a decision. If still in doubt have a pro come out and take a look. Advice is free in most cases.
