Sample Thailand Associate Architect — Main Architecture Practice Questions

Try these sample questions to review concepts for the Thailand Associate Architect — Main Architecture exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 50+ question experience with AI tutoring.

1Which relationship defines Floor Area Ratio (FAR / อัตราส่วนพื้นที่อาคารรวมต่อพื้นที่ดิน)?

A.Counted total building floor area divided by site area

B.Building footprint divided by site area

C.Open space divided by counted total floor area

D.Net usable floor area divided by gross floor area

Explanation: FAR compares the floor area counted under the applicable planning rules with the site area. It measures development intensity across floors; it is different from the proportion of land covered by the building footprint.

2In Bangkok planning terminology, what is the denominator when calculating Open Space Ratio (OSR / อัตราส่วนของพื้นที่ว่างต่อพื้นที่อาคารรวม)?

A.The total site area

B.The building footprint

C.The total building floor area counted by the applicable plan

D.The net rentable floor area

Explanation: OSR expresses required open space as a percentage of the building floor area counted by the plan. It should not be confused with open space expressed as a percentage of site area, and the plan's definitions determine which areas qualify.

3A 2,000 m² site has a permitted FAR of 5:1. Considering the FAR limit alone, with no bonus floor area, what is the maximum counted total floor area?

A.4,000 m²

B.7,500 m²

C.12,500 m²

D.10,000 m²

Explanation: Multiply the site area by the permitted FAR: 2,000 × 5 = 10,000 m². This is an FAR ceiling; setbacks, open-space requirements, access and other controls may reduce what can actually be built.

4For this exercise, a development has 8,000 m² of counted total floor area and a minimum OSR of 10%. How much qualifying open space is required?

A.800 m²

B.400 m²

C.1,600 m²

D.200 m²

Explanation: Required open space is 8,000 × 0.10 = 800 m². The percentage applies to counted floor area, and the proposed open space must also satisfy the applicable plan's definition.

5Which pair of seasonal wind systems should inform an initial natural-ventilation study for Thailand?

A.Northwest and southeast monsoons

B.A year-round southwest monsoon

C.A year-round northeast monsoon

D.Southwest and northeast monsoons

Explanation: Thailand experiences seasonal southwest and northeast monsoons. Local wind records, terrain and nearby buildings still need investigation; the northeast monsoon can bring substantial rain to the Gulf-facing south rather than uniformly dry weather throughout the country.

6A sun-path study identifies high-altitude midday sun as the main unwanted exposure on a south-facing window. Which external device most directly provides a horizontal cutoff angle?

A.Vertical fins perpendicular to the facade

B.A vertical screen beside the window jamb

C.A reflective coating with no projecting shade

D.A horizontal overhang above the window

Explanation: A horizontal overhang above the opening intercepts high-altitude sunlight before it reaches the glass. Its depth and position should be calculated from the actual sun angles and window geometry rather than selected from orientation alone.

7Under Thailand's building accessibility regulation, as amended in B.E. 2564, what is the maximum slope for the ramp specified by its general ramp provision?

A.1:12

B.1:6

C.1:8

D.1:10

Explanation: The regulation limits the ramp slope to 1:12, meaning one unit of rise for twelve units of horizontal run. Slope is only one requirement: clear width, landings, handrails and edge protection must also be checked.

8An accessible ramp is proposed as a single uninterrupted 9 m sloping run. Under Thailand's accessibility regulation as amended in B.E. 2564, which revision addresses the ramp-run length requirement?

A.Keep the run and add a handrail at its midpoint

B.Keep the run and increase its width

C.Divide it into runs of at most 9 m with a 1 m landing

D.Divide it into runs of at most 6 m with an intervening landing at least 1.50 m long

Explanation: The amended provision limits each sloping run to 6 m and requires a landing at least 1.50 m long between runs when the ramp is longer. Handrails and width remain separate requirements and do not replace the landing.

9What minimum diameter of clear wheelchair turning space does Thailand's building accessibility regulation require inside an accessible toilet?

A.1.20 m

B.1.80 m

C.1.50 m

D.0.90 m

Explanation: The regulation requires clear space allowing a wheelchair to turn within a circle at least 1.50 m in diameter. This is a turning-space requirement, not a statement that a complete toilet room can be only 1.50 m square; fixtures, transfer space and door operation require additional planning.

10Which distinction should guide the use of warning and directional tactile walking-surface indicators?

A.Warning indicators are for outdoor routes and directional indicators are for indoor routes

B.Warning indicators identify every material change and directional indicators identify lighting changes

C.Warning indicators replace handrails and directional indicators replace signs

D.Warning indicators alert users to a hazard or decision point; directional indicators guide travel along a route

Explanation: Warning and directional indicators communicate different information through detectable surface patterns. Their placement must follow the applicable accessibility details so that a warning cannot be mistaken for an instruction to continue walking.

Thailand Associate Architect — Main Architecture: Suggested Study Strategy

1Read the Council's current Main Architecture outline and sitting-specific Subject 11 design brief, then practice producing the requested drawings and design reasoning.

2For building-code calculations, identify the building category, measurement datum, applicable clause and any additional local controls before selecting a number.

3Distinguish material properties from complete-assembly performance, and coordinate structure, building services, accessibility and environmental design.

4Read the Council's current ethics rules, including the B.E. 2569 amendment, and distinguish actual professional involvement from signing work without review or responsibility.

5Use the Council's registration timetable for exact subject times and check eligibility, required training and licensing charges directly with the Council.

Frequently Asked Questions

Which Thai architectural licensing assessment does this bank cover?

It covers selected topics for the standard Associate Architect route in Main Architecture (ระดับภาคีสถาปนิก สาขาสถาปัตยกรรมหลัก), administered by สภาสถาปนิก. It does not combine the separate interior, landscape and urban architecture assessments or higher licensing tiers.

Is the official assessment a 50-question English MCQ test?

No. Fifty is the size of our practice bank. The Council's subjects include actual design work, and its rules allow subjective and/or objective written questions and interviews when prescribed. The published 2026 design brief is in Thai. Our English-language MCQ study adaptation is not an official translation or a simulation of the official format or language environment.

What eligibility and post-exam steps should candidates check?

Candidates need Council membership and confirmed eligibility in the relevant branch, including acceptance of their educational qualifications through the Council's process. The B.E. 2566 examination rules require eligible members to apply for their first test within one year of the eligibility announcement. Successful candidates must apply for the license, complete the required training and pay the applicable charges; passing practice questions does not confer a license.

What are the written pass mark and retake fee?

The Council's B.E. 2566 rules set at least 60% in each written subject, allow passed written-subject results to be retained for up to four years, and set THB 2,000 for a first examination application and THB 1,000 for a retake application. These are examination charges; other licensing costs are separate.

Are the topic percentages official examination weights?

No. They describe how OpenExamPrep allocated these 50 study questions. The currently linked Council outline lists the three subjects and their content but does not state the 30%, 36% and 34% practice allocation used here. Continue practicing design production and the full official scope alongside these selected MCQs.
