A
Portico / Deck Design in Oakville Ontario
This
project is in Old Oakville Ontario. We were asked to come up with
concepts and structural details to change the facade of this home. They
wanted a design strong enough to stand out in this very
prominent area near the water. We came up with the concept of
using the existing porch as a base for the new entrance portico-deck.
This is what we started with.
As it turned out, the previous owner of the home did not get
a permit to add on the porch, however the basement was accessible and
was a suitable frost wall to support the structure. It did necessitate
a permit application for the existing structure prior to building the
new atop it--and of course attending comittee of adjustment.
The existing situation had
an arched roof structure for decoration and a good deal of slope on the
patio, which enables water to drain, but had to be accomadated in the
design. The clients did mention it was slippery in the winter so we
settled upon an internal roofing system to allow a functional deck
above, and a dry area below.
Here
are the elevations we settled upon. Evestroughs bring the water out of
the floor structure. Architectural built up columns with trelliswork
inside designed to be lit from the interior and sculped laminated
oversized braces for structure and a decorative look.
The rails are trimmed for a custom look on thee exterior,
however code prohibited applying it on the internal face. From the
interior of the deck the most visible feature is the view, hardwood
decking and architectural appeal of the woodwork detailing.
These are some of the structural details that your building
department expects. Basically, everything the builder will do must be
detailed so that the inspector can assure safety and structural
suitability.
Framing
details must show spans, sizes of the lumber and direction of joists
and decking. Here we mounted the decking diagonally for additional
strength. When combined with the oversized braces this structure would
stand even after the home was blown down by a hurricane.
This is our detail for sealing decks from within. We use an
architctural membrane to roof the internal framing and that drains into
an evestrough.
Other details necessary for permits... connection to the
existing home, beams, hand rail post connections and post connection to
existing patio.
The final product... (copper evestrough and drain feature
were awaiting a tradesman at the time of this photo shoot). Comittee of
adjustment delayed this project right through the summer. That is a
lesson for everyone--get the plans done far in advance of when you want
to build. The closer to spring, the less chance you will have to get a
designer to accept your project--and less chance of it being when you
expect it.
The
front elevation of the finished project. We used TigerDeck Decking and
all materials were prefinished with Benjamin Moore ArborCote prior to
installation. The client shouldn't have to re-finish this for nearly a
decade. Oil the decking with an approved product and that's it.
Expect
a project like this to cost between $1200-1800 with concepts and
detailing. Your local building department may require BCIN Stamps in
Ontario, and or Engineering Stamp if you are in California or Florida
due to Hurricane or Seismic Factors.
This project
was designed by Lawrence Winterburn and the builder was Dan Maragno,
our Builder in Oakville Ontario.
