Overview
The D Plan
A real home office, built in.
A real home office means a door that closes, walls that block kitchen noise, and a desk that isn't your dining table. The D Plan's flex room sits on the ground floor next to the garage — away from the bedrooms and the main living level — the layout difference that turns "working from home" into actually working from home.
For two-earner households, it also means two productive workspaces under one roof — the flex room for one, a bedroom or the primary for the other — without converting the kitchen island into a call centre.
Plan layout
Three levels, four rooms that can host a closed door.
Ground floor: side-by-side double garage with EV rough-in, direct interior access, and the dedicated flex room next door.
Main level: open kitchen, dining and living, with quartz counters, oak cabinetry, a full appliance package, a powder room, and a balcony off the living area.
Upper level: three full bedrooms and 2.5 baths. The primary stretches the width of the home, with its own ensuite and walk-in closet.
Above it all: your private 675 sq ft rooftop patio — the largest at Addition — with gas BBQ hookup.
Rooftop + AC included
A 675 sq ft rooftop, AC, and EV-ready garage. Standard.
Every D Plan keeps the inclusions Addition is known for: private rooftop patio with gas BBQ hookup, central AC + heat pump, EV-rough-in side-by-side garage, Samsung appliance package, quartz counters, chevron-tile showers, and a Step Code 4 building envelope.
Nothing on the spec sheet is sold as an "upgrade". The rooftop is the largest of any plan; the AC is real central air, not a portable workaround.
Flex room, six ways
One room, many lives.
The reason the flex room earns its square footage: it doesn't lock you into one use. As your work, family and routines shift, the room shifts with them.
Home office
Doored, quiet, separable. Far enough from the kitchen for real video calls; close enough to step away between meetings.
Kids' playroom
Toys, art tables and Lego stay contained — leaving the main living floor for adults at the end of the day.
Guest space
Visiting parents, weekend friends, or an au-pair stay close — without giving up a kid's bedroom upstairs.
Home gym
A Peloton, a rowing machine, a yoga mat and a mirror. Workouts that don't get rearranged around the living room.
Hobby studio
A workbench, a craft station, a music corner, a podcast booth. Mess and gear stay out of shared rooms.
Storage + utility
Sometimes it's just the room that absorbs life — bikes, seasonal bins, an extra fridge for game days.

Frequently Asked
The D Plan, answered.
The most common questions about the 3 bedroom + flex layout — the flex room itself, who it suits, the rooftop, garage, AC, energy efficiency, and Phase 2 / Phase 3 availability.
What is a flex room?
A flex room is an enclosed bonus room – separate from the bedrooms – on the ground floor next to the garage. At Addition it serves equally well as a home office, guest room, gym, playroom, hobby space or storage – depending on what your household needs now and later.
How big is the D Plan?
1,645 sq ft of interior space across three levels, plus a 675 sq ft private rooftop patio – the largest layout at Addition.
How many bedrooms and bathrooms does the D Plan have?
3 bedrooms upstairs, a ground-floor flex room, and 2.5 bathrooms – a powder room on the main living level and an ensuite off the primary.
Where is the flex room located?
On the ground floor next to the side-by-side double garage – physically separated from the kitchen, living area and the three upstairs bedrooms, so it stays quiet during video calls and bedtime.
Is the D Plan good for work-from-home buyers?
Yes – this is the layout it was built for. A doored room, separated from main living and the bedrooms, with its own walls to block kitchen and household noise.
Can the flex room be used as a fourth bedroom?
It can be used for occasional guest stays, but it does not have a closet and isn't legally classified as a bedroom. For nightly use as a primary bedroom, one of the three upstairs bedrooms is the right answer.
Does the D Plan include a private rooftop patio?
Yes – a 675 sq ft private rooftop with gas BBQ hookup. It's the largest rooftop deck at Addition, designed for outdoor dining, lounging and entertaining.
Is air conditioning included?
Yes. Central AC + heat pump is standard on every home at Addition, including the D Plan – no upgrade fee.
Does the D Plan come with a garage?
Yes – a side-by-side double garage on the ground floor with direct interior access and an EV rough-in, situated right next to the flex room.
How energy efficient is the D Plan?
Built to BC Energy Step Code 4, one of the higher efficiency standards in the province – meaning a tighter envelope, better insulation, and lower long-term energy costs.
How many D Plans are available?
Phase 2 (now selling) includes 8 D Plans. Only 2 additional D Plans will be released in Phase 3 – 10 in total at Addition.
How does the D Plan compare to the 3 bedroom plans?
Plans A, B1 and B2 share the same standard inclusions – rooftop, AC, garage and finishes – without the ground-floor flex room. If WFH, guests or a gym are part of your life, the D Plan usually earns the difference in lived value.
