Task 2 Band 7

Cambridge IELTS 21 Academic Writing Test 1 Task 2 Band 7 Model Answer

You should spend about 40 minutes on this task. Write at least 250 words.
Write about the following topic: "The best way to provide enough homes in large cities is to build tall apartment blocks. To what extent do you agree or disagree with this statement? Give reasons for your answer and include any relevant examples from your own knowledge or experience."

The rapid urbanisation of large cities has created an urgent need for adequate housing, and some argue that constructing high-rise apartment blocks is the most effective solution. While I acknowledge that tall buildings can significantly increase housing capacity, I disagree that this is the best approach in all circumstances. Other strategies, such as suburban expansion and urban regeneration, are equally important in addressing the housing crisis.

On the one hand, building tall apartment blocks offers a practical and efficient way to accommodate growing populations in densely populated cities. High-rise developments make optimal use of limited land, allowing thousands of residents to live within a small geographical area. This is particularly beneficial in cities like Hong Kong and Singapore, where land scarcity is a critical issue. Furthermore, vertical living can reduce urban sprawl, thereby preserving green belts and agricultural land on the outskirts of cities. Tall buildings also support the development of public transport infrastructure, as a high population density justifies investment in underground trains and bus networks.

However, relying solely on high-rise construction presents significant drawbacks. Firstly, building upwards often leads to overcrowding and places immense strain on existing infrastructure, such as water supply, sewage systems, and road networks. Many residents in tall apartment blocks may feel isolated or experience poor mental health due to limited access to green spaces and natural light. Moreover, high-rise living can erode community cohesion, as residents often have little interaction with their neighbours. For example, in many Chinese megacities, although tower blocks have provided housing for millions, social isolation and a lack of community spirit have become growing concerns among urban planners.

In my view, a more balanced approach is necessary. In addition to building upwards, authorities should consider expanding suburban areas with well-designed housing estates that include parks and communal facilities. Another effective strategy is urban regeneration, whereby derelict industrial or commercial buildings are converted into residential units. This not only provides homes but also revitalises neglected neighbourhoods. Cities like London and Melbourne have successfully implemented such mixed-use redevelopment projects, which have increased housing supply while maintaining community character.

In conclusion, while tall apartment blocks are a valuable tool in tackling housing shortages, they are not the definitive solution. A comprehensive strategy that combines vertical construction with suburban expansion and urban renewal would be far more sustainable and beneficial in the long term.


Why this answer scores Band 7.0:

CriteriaHow the sample meets Band 7.0 requirements
Task ResponseClearly addresses the prompt with a balanced position (disagrees with "best way" but acknowledges benefits). Fully developed arguments with relevant examples from Hong Kong, Singapore, Chinese megacities, London, and Melbourne.
Coherence & CohesionStrong paragraph structure: introduction → benefits of tall buildings → drawbacks → alternative solutions → conclusion. Uses a range of cohesive devices: On the one hand, Furthermore, However, Moreover, In my view, In conclusion. Logical flow throughout.
Lexical ResourceGood range of vocabulary: rapid urbanisation, adequate housing, high-rise developments, urban sprawl, preserving green belts, strain on infrastructure, erode community cohesion, derelict, revitalises, mixed-use redevelopment. Uses collocations naturally (population density, public transport infrastructure, mental health).
Grammatical Range & AccuracyVaried sentence structures including complex sentences with relative clauses (where land scarcity is a critical issue), conditional structures, and passive voice (are converted). Good control of tenses. Minor errors only.

Why this is Band 7.0 (not 6.5 or 7.5):

AspectBand 6.5Band 7.0Band 7.5+
PositionClear but simplisticClear with nuanceSophisticated and fully developed

What holds this back from Band 7.5:

IssueExplanation
Vocabulary could be more sophisticatedWords like good, bad, important are avoided, but phrases like valuable tool and definitive solution could be replaced with more academic alternatives (panacea, optimal strategy).
Examples need more analysisThe examples (Hong Kong, London) are mentioned but not explained in depth. A Band 7.5+ would elaborate on why these examples support the argument.
Some repetitionHousing and tall buildings are repeated frequently. Synonyms like accommodation, residential units, dwellings, high-rises could add variety.
Conclusion could be strongerA Band 7.5+ conclusion would not just summarise but also offer a final compelling thought or recommendation.

Key tips for achieving Band 7.0 in Task 2:

  1. Address all parts of the prompt – In this case, you must state your position clearly (to what extent do you agree?).

  2. Structure with 4-5 paragraphs – Introduction, 2-3 body paragraphs (each with a clear topic sentence), and a conclusion.

  3. Use specific examples – Avoid vague statements; use real cities, policies, or general knowledge to support arguments.

  4. Show a range of vocabulary – Use topic-specific terms (urban planning, infrastructure, regeneration, density) and avoid repetition.

  5. Use complex sentences – Combine ideas with relative clauses, conditional sentences, and cause-effect structures.

  6. Write at least 250 words – Aim for 270-290 words for Band 7+.


Quick checklist for Band 7.0 Task 2:

  • Clear position in introduction

  • Balanced discussion (if discussing both sides)

  • Each paragraph has one main idea

  • Topic sentences are clear

    Band Score 5.5The best way to build enough home in big cities is to provide tall apartment blocks. I completely agree with this statement and I will explain the reasons and include examples. Making enough homes for people in a large cities is build tall apartment blocks because in a large city there is a lot of opportunities for people and they gather for their bright future from different areas and population increasing day by day by the area of cities is stable its not increasing. So to balance this huge population accommodation build tall apartment is a very good idea . For instance if we have a small area we can not make more houses but we can make the building taller and it can hold more people. Another reason it built tall buildings give us more space in building we can enjoy the weather of upper level wind and nature , we can enjoy the view of the city. The populations are increasing day by day but the land we use for grow crops and other thinks is not increasing so building the tall buildings give us more land to use them for our well being . And making more home make the city more disruption and gathering so making tall apartments is the solution and we can see it in out cities. To conclude building more tall home is the best solution for adjust people and its has some benefits we have more land to use grow crops and use them for well being.
