Building and Massing Presentation Module #4: Height Ratios and Unit Calculations
A
So
what
do
we
need
to
balance
when
we're
considering
building
height
the
you
know,
relationship
between
building
height
and
public
amenities,
the
number
of
parking
spaces
that
we
have
the
amount
of
area
we
can
dedicate
to
alternative
transportation?
All
of
these
things
are
based
on
how
much
land
we
dedicate
to
which
purpose,
and
so
I
want
to
explore
the
relationship
between
building
height
and
unit
count
and
look
at
how
that
affects
the
open
space
available
on
properties.
Just
take
one
view,
a
couple
of
parameters
and
look
at
how
they
interact.
A
A
A
This
is
just
a
model
to
help
us
understand
how
building
elevation
and
proportion
of
mix
of
building
elevations
affects
unit
count.
No
one
is
proposing
that
there
be
eight
story:
buildings
throughout
the
district,
certainly
not
throughout
the
entire
gateway
area,
and
so
this
is
for
modeling
purposes
only.
A
We
also
wanted
to
look
at
what
happens
if
you
limit
it
to
six
stories
so,
instead
of
allowing
for
eight
stories
in
the
barrel
district
that
is
currently
allowed.
What,
if
we
said,
six
stories
was
the
max
in
the
barrel
district
100
percent,
four
stories
100
six
stories,
so
the
proportions
changing.
So
these
proportions
are
the
same
with
four
and
four
six
and
eight
as
they
are
with
four
five
and
six.
A
A
Now.
The
first
thing
you
may
be
thinking
to
yourself
was:
that's
not
a
very
big
difference,
so
why
all
the
consternation
over
eight
stories
versus
some
lower
number?
I
think
that's
a
really
good
question
that
we
need
to
explore
and
that's
part
of
the
reason
why
we're
looking
at
this,
you
might
also
be
looking
at
the
four
story.
Unit
count.
A
100
4
stories
provides
3269
units
in
this
model.
Now
this
model
fixed
for
things
like
you
know,
average
unit,
size
and
so
on
and
so
forth.
So
these
are
all
relative
to
each
other,
and
so
you
might
be
thinking
to
yourself
well
3200
versus
3500,
that's
pretty
good
trade
off
too,
and
so
why
are
we
talking
about
larger
footprints,
larger
buildings?
We
should
be
just
focusing
on
four
stories
and
moving
forward.
A
I
wanted
to
look
at
the
lot
coverage
and
community
open
space,
that's
related
to
getting
to
those
those
unit
counts
and
so
fixing
for
unit
count,
in
this
case,
44
units
on
a
30
000
square
foot
site
we're
going
to
vary
the
building
footprint
based
on
the
number
of
floors
here
in
this
exercise,
and
so
you'll
see
in
this
plan,
gray
is
going
to
reflect
buildings.
So
lot
coverage
is
gray.
A
Open
space
is
going
to
be
green
right
now
you
see
the
parcel
that
we're
going
to
be
playing
with
here
in
green
and
black
gives
you
a
reference
for
the
sidewalk
and
we're
going
to
be
looking
at
site
plan
view
and
build
an
elevation.
So
this
is
going
to
be
the
side
view
and
there's
going
to
be
the
top
view
of
these
buildings
in
these
different
scenarios.
A
So
looking
at
a
three-story
building
three-story
building
in
order
to
hit
44
units
on
a
30,
000
square
foot
lot
with
the
parameters
that
we
used
takes
up.
100
of
the
lot
coverage
there's
almost
zero
open
space
in
this
model,
and
so
you
can
get
that
44
units
on
a
30,
000
square
foot
site
by
covering
the
entire
thing.
A
A
Looking
at
a
five-story
building,
you
only
have
59
of
the
lot
covered.
The
remainder
of
that
lot
is
open
for
other
uses,
still
getting
the
44
units
on
that
30
000
square
foot
lot.
So
when
I
go
back
to
the
example
of
the
model
where
it
showed
that
you
can
get
just
about
the
same
number
of
units,
all
of
the
things
being
equal
out
of
100
4
stories
versus
a
mix
of
four
six
and
eight
or
a
mix
of
four
five
and
six,
that
is
true,
you
can
get
about
the
same
number
of
housing
units.
A
The
question
that
you
have
to
ask
then
next
is
how
much
of
that
space
in
this
area.
Do
I
want
to
dedicate
to
getting
those
housing
units?
So
here's
where
we
need
to
weigh
the
policy
decisions
against
providing
more
housing,
finding
more
open
space
or
providing
other
amenities
within
the
community,
now
reflect
this
green
space.
Here,
that's
on
this
five-story
building.
Some
of
that
could
be
dedicated
to
the
uses
on
that
site,
so
you
might
have
some
private
recreation
space
for
the
users
of
that
site.
A
But
one
of
the
core
features
of
this
program
is
that
these
these
new
developments
will
also
contribute
to
the
public
realm
and
so
we'd
be
able
to
get
a
tot
lot
or
maybe
a
nice.
You
know
corner
parklet
or
a
seating
area
or
you
know
expanded
sidewalks.
So
these
kinds
of
public
amenities
can
come
out
of
allowing
for
taller
buildings
that
free
up
more
of
the
site
for
other
uses.
