build on

use a past success as a base for more progress

B2

What does "build on sth" mean?

To build on something means to take an existing success, achievement, or positive situation and use it as a platform to go even further. The idea is one of forward momentum — you are not starting from zero, but rather treating what you have already achieved as a foundation for the next stage. This phrasal verb carries a naturally optimistic, forward-looking tone, which is why it appears so often in business strategy, sports commentary, education, and motivational contexts. It is slightly different from simply 'using' something: building on implies that what came before actively propels you towards something greater. You will often hear it paired with words like success, progress, momentum, strengths, and experience, or followed by a clause like 'what we've achieved so far'.

Examples

How to use it

build on + noun phrase

The most common pattern — a person, team, or organisation uses a named achievement or quality as a springboard for further progress.

The company needs to build on its recent success if it wants to expand into new markets.

modal + build on + noun phrase

Very frequently appears after modal or intentional verbs like 'need to', 'want to', 'must', and 'hope to', reflecting the forward-looking nature of the phrase.

We must build on our strengths rather than focusing too much on what went wrong.

build on + what-clause

When the base for progress is described more fully, a 'what'-clause after 'on' is a natural and common alternative to a single noun.

The new manager wants to build on what the previous team achieved over the last two years.

build on + pronoun (it / this / that)

Pronouns always come after 'on', never between 'build' and 'on', since the verb is inseparable.

The first quarter results were encouraging — now we just have to build on them.

be building on + noun phrase

The present continuous form is used to show that the process of using a foundation for further growth is actively underway.

She is building on her early-career experience to move into a more senior leadership role.

Common Mistakes

Trying to separate the verb

Unlike some phrasal verbs, 'build on' cannot be split — the object must always come after 'on', never between 'build' and 'on'. This applies to nouns, pronouns, and clauses alike.

✗ We need to build our progress on.
✓ We need to build on our progress.
Confusing 'build on' with 'build up'

'Build up' focuses on gradually increasing or accumulating something, often from a low starting point. 'Build on' specifically means using an existing achievement as a base to go further — the starting point is already a positive one.

✗ After months of training, she finally built on her fitness levels enough to compete.
✓ After months of training, she finally built up her fitness levels enough to compete.
Using 'build on' in the passive

Because the object of this phrasal verb follows the preposition 'on', it cannot naturally be moved to the subject position, making passive constructions awkward. It is best to keep 'build on' in the active voice.

✗ The success was built on by the team for the next campaign.
✓ The team built on their success for the next campaign.

Usage

This phrasal verb is neutral in register and works in both spoken and written English. It is especially common in business, sports, and educational contexts when talking about using past achievements as a springboard for further progress.

Frequently Asked Questions

What kinds of things can you 'build on'? Can it be anything?

The object is almost always something positive — a success, achievement, skill, relationship, or strong performance. The logic is that it serves as a foundation for something even better. You would not typically 'build on' a failure or a negative situation, as the phrasal verb carries an inherently forward-looking, optimistic tone.

Does 'build on' always refer to literal building or construction?

No — in this sense, 'build on' is entirely metaphorical. It has nothing to do with physical buildings or construction. It describes using a positive situation or result as a platform for further progress, much like a builder uses a solid foundation to construct something taller.

Can I use 'build on' in the past tense to talk about historical progress?

Yes, the past simple works very naturally: 'The company built on its early gains to become a market leader.' You can also use the present perfect to connect past progress to the present: 'They have built on last year's results to achieve record profits this quarter.'

Is 'build on' suitable for formal writing, like reports or essays?

Yes, it works well in both formal and informal contexts. You will find it in business reports, academic writing, speeches, and everyday conversation. It is neutral in register, so there is no need to replace it with a more formal alternative when writing professionally.

What is the difference between 'build on' and 'draw on'?

'Draw on' means to make use of a source or resource — for example, drawing on your experience to solve a problem. 'Build on' goes a step further: it implies that the existing achievement or quality is a launching pad that actively carries you to a higher level of progress, not just something you tap into.
