Step 2: Design Brief
Step # 1: Identify the Problem:
You are a builder, who has recently bought a vacant building lot in a residential subdivision.
Step # 2: Design Brief:
Design and build a residential house on the property to maximize profit from the land.
Step # 3: Investigation:
What will be the length and width of the house? 12000mm x 15000mm
How high will the house be? And how high will each floor be?
The house will be 7700mm in height, with each of the two floors being 3000mm, and the roof being 1250mm with the foundation coming above the zero point by 450mm.
What types of rooms are required?
On the first floor, the home will have an open foyer leading into a separate dining room, living room, family room, kitchen, laundry room and a 2 -piece bathroom/powder room. There is a staircase leading up to the second floor, where there will be a walkway on all sides of the opening accessing the 2 bedrooms, office, a 4 - piece bathroom and a master bedroom having a 5 - piece master bath ensuite and a walk-in closet.
Where do I use what doors?
For the entrance, I need to use exterior metal double doors, each being 810mm wide. For the back entrance, from the deck a glass sliding door is required, 1800mm wide. The kitchen, dining and living room all have a double casement archway being 1520mm wide. For all washrooms, a single door at 610mm wide is needed. Lastly, for the laundry room, family room, office and all of the bedrooms a single at 760mm wide is required. All doors are 2000mm high.
How will I make stairs?
The stairs must be 3000mm high, with each stair rising 150mm in height, by a depth/length of 300mm and a width of 1000mm. In addition, there is a landing of 2500 x 1000mm required to separate the 10 stair segments. Lastly, there must be 500mm gap in between each staircase connected to the landing.
What types of windows will I be using?
There is a double casement window with a width of 1625mm. There is a single casement window at 725mm wide. All windows are 1000mm high. What will be unique about the design of is house? The front entrance will be is protected from the elements by the second level overhang. There will also be a two-story center lobby that will welcome you into the house.
What will be used for outside finishings?
The exterior of the house will be brick, the roof covered in shingles and the foundation made of concrete.
What storage spaces are needed?
The main floor entrance must have access to a closet (1300mm x 550mm), the upstairs must have a linen closet of (1300mm x 550mm), each bedroom must also have a closet (1300mm x 550mm), and the master bedroom must have a walk-in closet (2000mm x 1500mm).
What will be the thickness of the walls?
The exterior walls will have a thickness of 150mm and the interior walls will have a thickness of 115mm.
What materials are available for the landscaping?
Astro-Turf, Small Stones, Sticks, Fake Flowers, Fake Trees, Fake bushes, Plastic and interlocking for the driveway and rear patio.
How big is the lot for landscaping?
The lot is 25000 x 25000mm, and after the house is built will allow for 5000mm of space on either side of the house and in the back. The front will have 8000mm available for landscaping and parking.
Step 3: Solution Draft:
See Auto CAD drawings attached. NOTE: The following is based on a show model of the house with a 1:25 ratio between house and model. (Not all same materials would be used for the real house) Shape is same to scale. (Auto CAD drawing are in the regular size, thus must be divided by 25 for the model)
Step 4: Material List
-Masonite 1000mm x 1000mm th-10mm height-18mm
-Hot Glue Gun Rods (With Resin)
-Wood Sticks(As Provided)
-0.5” Finishing Nails
-Small Fake flowers/trees/shrubs
-Dowel (4mm radius)
- Interlocking Tiles
-0.5” Finishing Nails
Step 5: Tool List
-L-Shaped Meter Stick
Spacers at 16mm
Step 6: Cutting List
Step 7: Fabrication
Cut all foundation pieces on the miter saw as indicated in the Foundation Cutting List using the meter stick, pencil, and square to mark out the pieces in the wood.
On the base measure and mark a rectangle 318mm from the front and 198mm from the back and two sides using the meter stick, pencil, and square.
Using the auto cad drawings organize the foundation pieces into the correct positions inside the rectangle and using the hot glue gun to secure them together and the L-Shaped measuring stick to keep them square.
(Note: Glue the inside edges to each other without gluing under the foundation pieces)
Cut a wood plank to fit from either side of the foundation wall the width of the house.
Glue in the wood plank in the middle so it is flush at the top of the foundation walls.
Measure and cut 2 pieces out of wood with the same thickness to fit from the base to the support beam.
Glue them in 1/3 of the way from each wall to support the support beam.
Using the wood sticks, use Miter scissors to cut them on angles and the Band saw for straight cuts, cut the pieces so they fit in the middle of the foundation, so as to maintain the shape of the house.
Glue them in the same way as the foundation was glued in.
Going the opposite direction of the foundation support beam, measure, cut and glue in cross beams to fit 16mm apart, starting at the side of the house.
Make all 14 walls by first cutting the pieces in the Wall Cutting List.
Next for each wall start with 2 C1’s and 30 C2’s.
Take 2 C2’s and make a rectangular frame with the C1’s so the C1 pieces are glued over the C2 pieces.
All walls are glued with the thickness side of the planks facing out.
Starting with one side, space 16mm and glue in the next C2.
Continue spacing and gluing from the same side until the wall is complete.
Repeat for the other 13 walls. 7 walls will be on the first floor and 7 for the second.
Cut to fit all of the exterior and interior walls on the Floor Plan Auto CAD drawing out of the full walls using the miter scissors.
Another C2 piece is required to end any wall that has cords extending past the previous stud.
This situation will arise if/when a cut is made in-between any 2 studs that is not right up against the last stud of that wall.
Cut and Glue all windows and doors according to the diagrams/specifications for construction for each of those items.
To make a window you need to glue the 40mm pieces outside of the widths given for each particular window to make a frame that has an exact height of 40mm.
To make a door you need to glue the 80mm pieces outside of the widths given for each particular door to make a frame that has an exact height of 80mm and has one open side.
Mark where each door and window will go on your walls using a meter stick, square and pencil. Refer to the floor plan Auto CAD drawing to get exact measurements. Install all windows and doors.
To install a door take the measurement of where it is to goes in the wall and remove any studs in the way of the door. Cut the bottom to the width of the door.
Glue the door in at the bottom. For the top of the door glue a beam horizontally between the 2 studs remaining.
Cut 4cm sticks to fit in vertically in between the beam and the top cord above the door.
Insert them with 16mm spacing above the door.
To install windows measure 40mm from the bottom of the wall up and make a line across.
Remove the studs that are in the indicated spot for the window.
Make 2 horizontal beams to fit and place and glue one in just under the 40mm line.
Glue the window in the indicated spot.
Glue a beam horizontally on top.
Measure the space from the bottom cord to the first beam and the top beam to the top cord.
Cut the removed vertical beams to those lengths (30mm and 40mm) and glue them in at 16mm spacing.
Mark and glue all finished walls to the top of the cross beams in there correct places using the meter stick, pencil square and L-Shaped Meter Stick.
Measure and draw the outline for the staircases on wood with a thickness of 20mm.
Each riser being 6mm and each stair being 12mm in depth. Make 2 staircases with 10.
Cut the wood on the outlines drawn, and then cut each piece in the middle through the thickness.
Each stair must be 40mm wide so cut a total of 20 planks at 40mm.
Cut and Glue sticks to fit onto each stair.
Cut and Glue a 100mm x 40mm frame for the landings of the stairs.
Cover the top with sticks by cutting to fit and then gluing them on.
According to the Auto CAD drawing mark out and glue in insert the stairs and landings in and outside of the house Cut and glue one picket to each stair on the side that is furthest from the wall.
Cut to fit half sticks to lie across the dowel segments as a handrail and glue them into place.
Cut and glue together the wooden sticks to fit the perimeter of the second floor and tape it onto the top of the first floor.
Mark, cut, and then glue sticks on top of the perimeter of the first floor with the wide face of the stick facing down.
Repeat step 6
Repeat steps 8-12 for the second floor Mark and cut out a 4cm by 4 cm square hole in the center of the 2nd floor in the cross beams using the miter scissors.
Connect each of the now unsupported crossbeams in the floor on each side of the hole by cutting to fit and then gluing a stick on the underside of the second floor.
Build four perimeter frames of front porch and one of the back deck according to the dimensions on the First Floor Auto CAD drawing out of sticks.
Cut to fit sticks to cover the top of one of the porch frames and the deck.
Glue all four of the perimeter frames of the front porch together with the top layer being the one that is covered. Glue the complete front porch into place according to the First Floor Auto CAD drawing.
Glue an O2 onto the underside of the back deck at the two corners furthest away from the house Glue the complete back deck into place according to the First Floor Auto CAD drawing.
Measure and draw the outline for the staircases on wood with a thickness of 20mm.
Each riser being 6mm and each stair being 12mm in depth. Make 2 staircases each with 3 risers.
Cut the wood on the outlines drawn, and then cut each piece in the middle through the thickness. The front porch staircase should have a width of 6 cm and the back should have a width of 3 cm.
Cut and Glue sticks to fit onto each stair. Once the staircases are complete glue them into place according to the First Floor Auto CAD drawing.
Glue an O2 vertically to each corner of the front porch and back deck and on every stair leading up. Measure, cut and glue a half stick over top of the O2’S.
Construct the rectangular frame for the roof by measuring cutting to fit a rectangle with a 5cm overhang on each side of the house.
Going the opposite direction of the foundation support beam measure, cut, and then glue in cross beams to fit 16mm apart, starting at the side of the house leaving the 5cm over hang open at over the sides of the house.
Measure, Cut and Glue in 5cm sticks 16mm apart from one another all along the open sides of the roof rafters.
Make a 3 sided rectangle using a sticks that reach 50mm in height, that is 1/3 the width of the roof and lies in the direct middle.
Cut to fit sticks to connect all four corners of the roof frame to the corners of the roof support beam.
Measure, cut and glue sticks extending from the left side of each rafter of the roof to the roof support beam or corner support beams.
Measure, cut and glue sticks extending from the left side of the 5 cm side overhang sticks to the roof support beam or corner support beams.
Clean up the glue.
Draw out the landscaping on the maisonite base using a meter stick, square, and pencil.
To make the slope of the grass mark lines 5 cm apart all around the area where there will be grass.
Cut to fit each O1 to fit the distance between the house and end of the property along each line.
Mark and then cut all of the cardboard rectangles in half along the distance between opposite corners the exacto knife.
Glue down each of the cardboard squares on the 5 cm lines so that to extend from the top of the foundation to the edge of the surface.
Cut cardboard and mould to create slopes around your project.
Cut and glue grass turf to fit on the slope leaving some overhang to wrap underneath the maisonite board.
Build flower beds by gluing 3 layers of small stones to form barriers in front of the all first floor windows on the back and sides of the house.
Insert fake flowers into the flower beds.
Glue fake bushes anywhere else around the house where the grass meets the foundation.
Cut to fit and glue down segments out of the stone tiles to fit the shape of the interlocking.
Grout the cracks.
Using a sponge wipe off any excess grout over the stones tiles. Insert small stones under the back porch.
Glue down any trees and other objects that you may have to place around the house.
Step 8: Staircase
Step 9: Evaluation
The first flaw in our design was that we did not glue in the stairs at a 90 degree angle which leaves a 1mm gap between the wall and the left side of the stairs leading up from the first floor to the landing The second flaw in our design is that we did not use full-length pieces to cover the front porch resulting in having to use wood filler to cover the cracks in between the sticks. Despite our best efforts the seam is still very evident and looks very ugly. The third mistake was that we made was that we did not sand the tops of the handrails on a 45-degree angle leaving space in between the handrail and the pickets. The fourth and largest mistake of this entire project was that we were not very careful when gluing the pieces together and so as a result, there is excess glue left on top of the seam. This was a careless mistake and we’re very ashamed of ourselves. We believe that we would have paid more attention to what we were doing we most likely would have been able to do a neater job and not of had to go back and cut off excess glue. On the bright side, the extra glue reinforces the attachment of each stick making our house more durable and less likely to break in the event falling (or smashing).
We have a be nice policy.
Please be positive and constructive.
