Think about function first
Design means planning a space so it does its job well. Before buying anything, ask: What will people do here?
- A bedroom: sleep, change clothes, store things.
- A study room: read, write, use a computer.
- A classroom: listen, discuss, move around safely.
Each job gets a zone, an area set aside for it. Put quiet zones together and noisy zones together.
Room layout and clear paths
Layout means where each piece of furniture goes. Follow three easy rules.
- Keep a path about 80 cm wide from the door to the main places.
- Put big items (bed, wardrobe) against walls to leave the middle free.
- Keep doors and windows free so they can open.
Measure the room and furniture first. Furniture that is too big makes a room feel crowded.
Light, colour and furnishings
Light
Daylight is free and good for the eyes. Put desks and reading corners near windows. Use lamps for evenings and dark corners.
Colour
Light colours (cream, pale blue, white) reflect more light and make a room look bigger. Dark colours (deep green, brown) absorb light and make it look smaller and cosier. Use one main colour, one second colour and a small bright accent such as a cushion.
Furnishings
Curtains, rugs, cushions and plants add comfort and style. Choose simple, strong, easy-to-clean things.
Improving campus spaces
A school campus is a shared space for many people. To improve it, first observe: where do students gather, where is it too hot, where is it unsafe?
- Shade trees cool the ground and clean the air.
- Benches give rest and a place to talk.
- Play and sports areas keep noisy games away from classrooms.
- Paved paths join places and keep shoes clean; add ramps for wheelchairs.
- Dustbins and a garden keep it tidy and calm.
Ask students and teachers what they need, then plan.
Drawing a floor plan
A floor plan is a drawing of a room seen from above, like a bird.
- Measure each wall in metres.
- Choose a scale, for example 1:50 (1 cm on paper = 50 cm in real life).
- Draw walls as thick lines, leave gaps for doors and windows.
- Draw furniture as simple boxes to scale.
- Write the room name and sizes.
Area of a rectangle room = length × width.
Try it: redesign your room
Measure your room with a tape. Draw it on squared paper at 1:50. Cut paper boxes for furniture at the same scale. Slide them around until the door path is clear and the desk is near the window. Then pick a colour plan.
Key formulas and definitions
- Area of room = length × width (m²)
- Plan size = real size ÷ scale (1:50 → 4 m = 8 cm)
- Clear path width ≈ 80 cm or more
- Colours: 1 main + 1 second + 1 small accent
- Zones: sleep, study, store
Worked examples
1. A room is 4 m long and 3 m wide. Find its area and its size on a 1:50 plan.
Area = 4 × 3 = 12 m². Plan: 400 cm ÷ 50 = 8 cm and 300 cm ÷ 50 = 6 cm, so an 8 cm × 6 cm rectangle.
2. A desk is 1.2 m long. How long will it be on a 1:20 plan?
120 cm ÷ 20 = 6 cm.
3. A small, dim study room feels cramped. Give two changes.
Paint the walls a light colour and move the desk to the window. Light colours reflect light and make the room look bigger, and daylight helps reading.
Common mistakes
- Buying furniture before measuring the room. It may not fit or may block the door.
- Placing furniture so the walking path is blocked. Always check the door-to-desk path.
- Using dark colours in a small, dim room. It will feel even smaller.
- Forgetting the scale on a plan, so rooms are drawn the wrong size.
