#21 "30 Frequently Asked Questions About Interior Perspective Requests": A Complete Guide for Beginners to Avoid Confusion and Know Before Ordering
― A summary of common stumbling blocks in architectural and CG perspective production: Interior Perspective (Living Space) Edition ―
When requesting interior perspectives, many people say, "I don't know what or how much information I need to provide."
This is because there are more decision-making points unique to interiors than you might imagine—such as furniture placement, material selection, brightness and lighting atmosphere, and how to incorporate a sense of daily life—making the initial areas of uncertainty more complex than for exteriors.
Therefore, in this article, we have compiled 30 of the "most frequently asked questions" before requesting interior perspectives, especially for residential spaces like houses and apartments.
We cover everything you need to know as a first step, including necessary materials, how to think about composition, tips for staging, and how to consider costs.
An interior perspective is not just about drawing a space, but a collaborative process of creating "what kind of lifestyle and experience to capture."We have summarized only the basics in an easy-to-understand way so that even beginners can proceed with confidence, so please use this as a checklist before your meeting.
The questions are arranged according to the
"Quote → Production → Delivery" flow, but if you only want to read about specific concerns, you can select the necessary items from the table of contents.Please proceed in an order that is easy for you to read, according to your own situation.

▼ Questions before requesting
Q1. What materials are required for interior perspective production?
A1. The basics are these three items: floor plans, elevation drawings, and finish schedules. If you have not only PDFs but also CAD data (DXF or DWG) for the drawings, reproducibility will be higher and production will proceed more smoothly.
In some cases, if you have a 3D model, it can be repurposed.
Also, if there are specific requirements for custom-made or loose furniture, sharing as much information as you have will improve accuracy.
Q2. Can I request a perspective even if the drawings are not finalized?
A2. It is possible to produce them even if the drawings are not completely ready.
However, it is very important to share at the beginning which parts are undecided and what kind of additional information might come up in the future. We will build the space based on the confirmed scope and use temporary settings for the parts you are unsure about.
Since significant changes to drawings during production lead to major rework, it is also a key point to summarize the information that is already decided as a direction at the beginning.
Q3. Do I need to decide on the furniture layout?
A3. If the furniture layout is decided, we will reflect that content; if you are unsure, we can propose a layout that fits the space.
Since furniture placement greatly influences the impression of an interior, sharing your intentions and goals—such as "I want it to look spacious" or "I want it to feel calm"—will make it easier to create the optimal configuration.
We will make detailed adjustments as necessary, but it is smoother to decide on the general layout policy at the beginning.
Q4. What should I do if the materials are not decided?
A4. You can proceed with production even at a stage where materials are undecided.
However, sharing one or two reference photos with a similar image will allow us to accurately grasp the direction at the initial stage.
Elements such as color, texture, and brightness greatly affect the impression of the space, so
telling us your preferred taste or tendencies you want to avoid—such as "I prefer it bright" or "I like calm tones"—using photos or images will increase reproducibility.
It is also possible to adjust the final material selection at the stage before finishing.

▼ About how to convey your wishes
Q5. How much should I verbalize my desired taste?
A5. It is fine if you cannot verbalize your desired taste in detail.
Even just using words that indicate a general direction, such as "hotel-like," "Scandinavian-leaning," or "natural and bright," is enough to grasp the worldview.
Sharing a few photos of spaces you like is the most accurate method.
We will read the color, texture, and atmosphere from the photos and appropriately assemble the tone of the entire space.
Even if you cannot verbalize it, sharing the "atmosphere you are aiming for" at the beginning will make the direction of the finish clearer.
Q6. How should I convey my wishes if I have few reference images?
A6. It is not a problem even if you have few reference images.
If you have even one image that says "this is close to the atmosphere," we can grasp the direction at the initial stage.
Even if you cannot prepare any images at all, sharing a few keywords such as "bright," "calm tone," or "minimal sense of daily life"—regarding color, brightness, texture, and the degree of daily life—will help determine the direction.
Based on the information provided, we can also proceed while proposing multiple atmosphere patterns.
Q7. Can I specify the presence or absence of a sense of daily life and the amount of furniture?
A7. We can make detailed adjustments according to your wishes.
Since the impression of the space changes significantly depending on the direction—such as "I want it to be organized like a hotel" or "I want to bring out a realistic sense of daily life"—sharing your intent at the beginning will help us get closer to your wishes.
The amount of furniture, the taste of small items, and the presence or absence of a sense of daily life require an optimal balance depending on the purpose (for advertising, for sales materials, for review, etc.).
If you tell us the purpose, we can propose the most effective configuration for showing the space.
Q8. Is it okay to have abstract wishes like "bright" or "calm atmosphere"?
A8. Abstract expressions like "bright" or "calm atmosphere" are fine, but since the impression of even the same "bright" can change significantly depending on the color temperature and illuminance of the light, having specific information that shows the direction, such as images, will make the initial understanding much faster.
If you haven't solidified your image, we can present multiple lighting patterns and atmosphere proposals for you to choose from.
Even rough preferences can be sufficiently shaped, so please feel free to share them.
Q9. What is the best way to convey the view outside the window?
A9. The way to convey it depends on how much you want to reproduce the view outside the window.
If you want to reflect the actual view, a photo taken from the window is the most accurate method. Since we can grasp the orientation and height of the building as well as the surrounding environment, we can also appropriately reproduce how light enters the room.
On the other hand, if you want to create an ideal view, sharing reference images with a similar atmosphere is sufficient.
Since the brightness, color temperature, and background density outside the window greatly affect the impression of the interior, deciding on the direction early will stabilize the overall finish.

▼ Questions about costs
Q10. What criteria are used to determine the estimate? (Interior specific)
A10. Estimates are largely determined by "volume of the space" and "complexity of the content." Also, since the amount of decoration affects the man-hours, the more complete the drawings, specifications, and reference images are, the higher the reproducibility and the more accurately the estimate can be calculated.
Q11. In what cases are additional costs likely to occur?
A11. Additional costs are likely to occur in cases where the work process changes significantly. Specifically, this includes "changing the angle," "changing the space/structure," "completely replacing furniture," and "changing the lighting plan."
These are items that tend to increase man-hours because they require rebuilding the model or re-rendering.
On the other hand, minor adjustments or fine-tuning of the direction can often be handled without additional costs.
Q12. Does changing furniture affect the price?
A12. Yes, it may affect the price.
If existing 3D models can be reused, additional costs can be kept down, but if original furniture needs to be reproduced from scratch or if detailed work is required, the number of processes increases, which is reflected in the cost.
Also, if major changes are made during production, rework is likely to occur, so if there is a possibility of changes, sharing them early will make the overall progress smoother.
Q13. What is the market price per interior cut?
The market price for one interior cut produced at GRUND is often in the 100,000 to 200,000 yen range.
However, it varies depending on the volume of the space and the amount of work required for reproduction for the project you are requesting.
Interior visuals tend to have more detailed work than exteriors, such as reproducing material textures, designing light, and optimizing furniture placement, which tends to increase the number of processes.
We will provide an accurate quote after reviewing materials such as drawings, specifications, and reference images.
Q14. Does the cost change if I request interior and exterior at the same time?
A14. By requesting interior and exterior at the same time, there are cases where it becomes easier to share the overall worldview and streamline progress. However, since the necessary processes and work content differ significantly between interior and exterior,
it does not become a flat-rate price like a so-called set discount. Since there are parts that can be streamlined if the overall composition is visible, we will propose the optimal form after reviewing the materials.
📌 Please also see this article for market prices and guidelines for costs.
▼ Questions about angles and composition
Q15. How should I decide the angle?
A15. The angle is determined by what you want to show as the main subject in the space. If you share which elements you want to center on, such as the kitchen, dining room, or living room, we can propose a composition that best conveys the spaciousness and flow of the space.
Q16. Is it possible to have multiple angles proposed?
A16. Yes, it is possible.
To grasp the characteristics of the space, it is common practice to present about three initial proposals at the early stage.
Also, since the optimal angle varies greatly depending on the purpose, such as for advertising, sales, or design review, sharing the objective will improve the accuracy of the composition.
If you would like an "angle hunt" to find the appropriate angle for your production goals, please let us know in advance.
Q17. Can I add perspectives from different angles using the same model?
A17. Yes, it is possible.
Once a spatial model is built, the process of generating different angles using the same data can be done relatively efficiently. This is also a good method if you want to change how the space is presented for different purposes, such as for advertising, sales, or design review.
Regarding costs, the additional amount will vary depending on the number of angles and the level of detail.
If you share the number of cuts required and your objectives, we can provide a proposal that fits your budget.
Q18. Can you make the room look larger than it actually is?
A18. It is possible to "create a spacious effect" using a wide-angle lens style.
However, if it is stretched too much, the sense of reality is lost, so it is important to find a balance within a range that does not feel unnatural.
Q19. Can you also provide suggestions for furniture layout?
A19. Of course, that is possible.
In interior perspectives, furniture placement is one of the most important points that greatly influences the impression of the space, so we can propose the optimal layout from a professional perspective. We will adjust it according to your goals, such as wanting to make it look spacious or creating a sense of luxury.
📌 This is a quick-read article about typical angles.
▼ Questions about the production process
Q20. What can be confirmed at the white model stage?
A20. The white model is the stage where you can confirm the "skeleton" of the space itself, the shape, size, and placement of furniture and accessories, and the overall atmosphere of the visuals.
The purpose of this stage is to refine the appearance of the space and objects purely, without being distracted by textures or colors.
If the composition and layout are firmly established here, the subsequent material setting, lighting adjustment, and finishing will proceed smoothly.
Q21. How much can I leave the selection of furniture and decorations to you?
A21. You can leave a fairly wide range of furniture and decoration selection to us.
If you just share "what kind of taste you want" at the beginning, we can consistently propose everything from furniture and lighting to accessories.
Furthermore, if you tell us which parts you want to leave to us and which parts you are particular about, we can make selections that meet your preferences.
Q22. Can you reproduce the furniture and home appliances I already own in the perspective?
A22. Yes, it is possible.
If you provide photos and dimensions, we can approximate the shapes. The "unique presence" of actual items, such as "highly designed furniture," "special home appliances," or "items that add a sense of daily life," is very effective as an accent for the space.
Q23. Can you switch between daytime, evening, and night views?
A23. Yes, by adjusting the "color temperature" and "intensity" of the light, we can accurately reproduce the atmosphere of each time of day.
Since the optimal tone varies depending on the purpose, such as for advertising, sales, or design review, the optimal tone changes depending on the purpose, so if you share your objective, we can propose the most effective time-of-day expression.
Q24. What is the most important factor that influences the atmosphere in an interior perspective?
A24. It is the handling of indoor lighting.
The impression of a space changes significantly depending on the color temperature of the lighting, how the light hits, and the depth of the shadows. Since textures are also strongly affected by light, sharing the lighting plan and color direction early on will lead to a more stable finish.
Q25. Are there any tricks to make a space look larger?
A25. By adjusting the camera position, angle of view, and furniture placement, you can make a space feel larger than it actually is. Simply reducing the amount of furniture or creating more space in the flow lines can significantly change the impression.
Since widening the camera angle too much can create a gap with reality, we adjust it while finding a balance that makes the space look naturally spacious without feeling unnatural.
Q26. Are there any points to keep in mind when summarizing revision instructions?
A26. Writing specific instructions directly onto screen captures is the most effective way to communicate.
Rather than using vague phrasing, it is more effective to identify the target by saying, "I want to change this part to X."
When multiple people are reviewing, various opinions may arise, so one key point is to consolidate your requests as much as possible before sharing them.
Q27. When requesting multiple cuts, in what order does the production proceed?
A27. First, we determine the common world view (materials, brightness, and taste), and then we decide the composition for each cut.
Once the spatial model is complete, the same data can be used to efficiently develop multiple cuts.
By finishing the "main cut" first to establish a standard, it becomes easier to maintain overall consistency and proceed smoothly with subsequent cuts.
▼ Regarding Delivery and Data
Q28. What is the average turnaround time for an interior perspective?
A28. While it depends on the size of the space and the amount of furniture, it generally takes about 2 to 3 weeks.
The more confirmed information you have, such as drawings, specifications, and reference images, the more smoothly the process can proceed.
Q29. Can I choose the delivery data format?
A29. Yes, you can.
Generally, JPEG or PNG are the most requested formats.
It is possible to adjust the size and color tone to suit your intended use, and we can also accommodate detailed requests such as adjusting margins to match your presentation materials.
In some cases, we can provide 3D model data for a fee, so please let us know before production begins if you are considering this.
Q30. Can you provide separate data for print and web use?
A30. Yes, we can.
We will prepare high-resolution, wide-color-gamut data for print, and lightweight data for web use.
If you specify the intended use, we can output the data with settings appropriate for each.
📌 Please see here for an explanation of the optimal delivery formats for each purpose.
Summary
These are the 30 most frequently asked questions when requesting interior perspectives.
Interior perspectives are visuals that express not only the space itself but also the time spent there and the atmosphere.
That is why, by knowing "what information is needed" and "what the decision points are" before making a request, it becomes easier to share your vision with the production team, and communication becomes significantly smoother.
I hope these 30 questions serve as a small guide for those considering interior perspectives.
By understanding the necessary materials, composition, and production concepts from the start, you can proceed with peace of mind.
