The main thing I see that is a problem is your organization of the article, in particular the title and the headings. I would replace the title Renting Office Space in Bangkok with a variation on the first subheading How to choose your Bangkok Office (research this for best title). Your subheading levels need to be consistent. You start out with a callout box with What should you consider when searching for office space in Bangkok? Which includes a number of factors to consider.
This is a good intro item as it answers the title question in one quick read.
The title for the callout box is automatically a L2. You then repeat the subtitle Things to Consider When Looking for Office Space in Bangkok as another L2 which you don't need. The first factor Price is currently bolded and underlined. You then use another callout box, with Sometimes Price Doesn't Matter You company needs to have a presence, which is followed by the second of the factors from the first callout box though you have changed it. In the first callout it is appearance and reputation, but when you list it to discuss it, you have Appearance and Name. This is bolded but not underlined. Drop the callout and add the text to the beginning of the paragraph as a transition from the last section and to introduce this section.
Make sure the content in each section is on topic. For the section on appearance and reputation (this is clearer than the term name so I'd use this) you have repeated information on choosing an inexpensive building in the first paragraph though you start by saying sometimes price doesn't matter and this section isn't on price. In terms of appearance, you only mention the lobby. What else might play a role in appearance? You mention the age of the building which could relate to appearance but could also refer to amenities, functionality, safety etc. Similarly, in the second paragraph of the section you discuss choosing a building close to a train station that is less expensive - Again, the section is not about price and you spend the rest of a large paragraph talking about the importance of being close to a train station for customers and staff. Again the section isn't about location or finding staff willing to work at the business. It is about appearance of the building and reputation. You finish the section with the following: "Please don’t underestimate the severity of Bangkok traffic, it’s no joke, and not everyone feels safe riding a motorbike to work. Let’s not forget, Thailand has the worst road fatality rates in the world." You have now introduced traffic, riding a morobike to work and Thailand's road fatality rates all of which is off topic. It is unclear whether you are talking about the reputation of the firm or of the building you choose. Since the article is about how to choose a building the reader will likely assume it is the latter.
Make sure the pictures are relevant and illustrate something specific about the article. Ex. the second picture is just a general office building and has the title Grade A office building in Bangkok (which gives it a L2 heading instead of caption), though the section before it is on building appearance and reputation so this picture doesn't add anything. Then there is a picture of a pen with the word "contract" and a couple of sentences about leasing agreements though there is no new subheading so it is still under the Appearance and Reputation section. You then have a number of questions about rent at the same subheading level as the sections.
The last section is Other Things to Consider which includes Car Parking
Typically office buildings will offer 1 car parking space per 100sq.m. of office space leased. So the manager is ok, but the rest of the staff will struggle!
Air Conditioning - if this is part of rent it can go in new leasing section. It is not currently listed in callout.
Termination - include this in new leasing agreement section. Aside from rent related factors what things are important when considering the lease?
Proximity to Restaurants - if you add a location section this can go there. Otherwise it should be listed in the callout in the order it's discussed.
Proximity to Banks - here you just say this is self explanatory. If it is that obvious you don't need to include it. Otherwise you should have some content here saying why it's important.
Go through the article and make sure everything is consistent and on topic. Add content to fill out the sections where they are incomplete. I would suggest using L3 subheadings for the the different factors since the callout introducing them is a L2. Discuss each factor in the order they are originally listed in the callout and keep the subtitles consistent with this. Say why each factor is important when deciding on a building.
Make sure each paragraph talks about only one thing which is related to the section it is in and follows from the one before, leads to the one after. Take out the link since it seems promotional especially as there aren't other ones such as one for the cheaper buildings for lease. Finally, carefully proofread the entire piece.
Hope this helps and doesn't seem too daunting. Good luck with the article.
