Constructing Sturdy Bones on the This Previous Home Harmony Cape Venture

Lincoln and Megan Pasquina took a daring path after they determined so as to add on to their vintage Cape in Harmony, MA. Working with architect Andrew Sidford, they settled on a design for his or her addition that merges fashionable model with the home’s conventional type.

On the coronary heart of the brand new plan is a high-ceilinged, open household room with a view onto the yard. “As you step by from the kitchen into the brand new household room, you’ll have vaulted ceilings and a wall of glass,” says TOH host Kevin O’Connor. “That’s the transition between outdated and new.” That wall of glass is greater than a visible deal with, nevertheless. It additionally does vital structural work. “It’s attempting to carry all that tumbler, nevertheless it additionally has to carry up the roofline above it,” says Kevin. TOH common contractor Tom Silva provides, “It’s important to take into consideration the burden, clearly, however you even have to consider the lateral power of the wind towards it. So it must be actually stiff.”

The dramatic fashionable addition additionally means giving the outdated home a brand new ridge beam. “We’re altering the pitch of the unique roof, and lengthening its size to seize that new addition.

So we’re placing a brand new backbone into the outdated home,” says Kevin. Key to each structural components is using engineered lumber: manufactured beams and posts that supply power and stiffness that’s more durable to get from common sawn wooden.

Making the Many of the View

Engineered posts and beams create a powerful wall to assist massive window openings. To satisfy the window wall’s structural necessities, Tom and Kevin used laminated veneer lumber (LVL) for the highest beam and headers, and parallel strand lumber (PSL) for the posts.

They fixed the posts to the beam with hardened structural metal screws, and hung the decrease window headers from the posts utilizing blind-nailed metal connectors. Sheathing the wall with structural panels ensured the required shear power.

Marrying Previous Construction with New

Rather than the home’s authentic 2X10 ridge beam, Tom and Kevin put in a built-up beam utilizing three LVLs. Constructing the beam on the bottom would have been simpler, however the hefty meeting would have been an excessive amount of for the telehandler to elevate on the finish of its growth extension.

So Tom and Kevin pieced the beam collectively in place. To account for the roof pitch, they offset the middle piece above the others. “When you observe the pitch of the rafters, the middle LVL pushes as much as keep within the aircraft of the roof,” Tom explains. “So whenever you lay the sheathing on the roof, you have got nailing on the prime, and your sheathing isn’t floating within the air.”
