Exterior Plans That Satisfy Homeowners! The Appeal of Visualizing Exterior Plans with LRTK

Introduction: Ideal exterior plans, but the problem of "hard to imagine"

When planning an ideal exterior (landscaping) layout for a new build or renovation, many clients (homeowners) struggle to picture the finished result in their minds. Even when shown drawings or perspective renderings (expected-completion images), it is not uncommon for them to worry, "What will it actually look like when it's finished?" Features such as gate posts, fences, the width of the approach, or the height of plantings may seem perfect on paper, but once completed on site people often feel, "This is not what I imagined…".

Mismatches caused by this difficulty in imagining the finished product can lead to homeowner regret and may result in additional work or touch-ups after construction. In fact, surveys of people with exterior construction experience have reported a fair number of cases where they were disappointed because the design on completion "didn't match their image". Even if considerable time and money were spent creating the ideal garden or parking space, satisfaction is greatly reduced if the finished product differs from what was imagined.

So how can we eliminate the anxiety and regret caused by this "difficulty imagining the finished image"? This article introduces the solution attracting attention: AR (augmented reality) technology and the use of "LRTK," which enables high-precision on-site visualization with a smartphone. We explain key points for reproducing the post-completion appearance at real size on site—something that drawings or photos alone could not convey—so homeowners can be convinced by exterior proposals.

Regrets caused by the gap between drawings and reality

One typical cause of homeowner regret in exterior planning is the gap between drawings or perspective renderings and the actual result. While it may be easy for professional designers to interpret the finished form from plan views or CAD drawings, it is not simple for ordinary homeowners to imagine a three-dimensional result from only flat drawings. Also, a sense of scale on paper often differs from what a person experiences when standing in the space.

For example, an approach (path to the entrance) that looked spacious on the drawing may feel "narrower than expected" when actually walked, or a carport chosen from a catalog may feel "surprisingly large and oppressive" compared to the building. The height and position of a fence might seem fine by the numbers on a plan, yet after completion people sometimes regret, "It blocks the view too much and feels oppressive" or "I should have made it a bit higher." Lighting brightness and the volume of plantings are also hard to imagine on paper, and it's not uncommon for homeowners to think "Huh?" only after seeing the real thing.

To avoid such regrets from these gaps, designers try to convey the finished image as much as possible using perspective drawings, models, and so on. Even so, they could not fully reproduce the site's atmosphere or harmony with the surroundings, and ultimately had to rely on the homeowner's imagination. As a result, there remained a risk that homeowners would end up feeling disappointed, thinking, "It turned out different from what I expected…."

Exterior proposals that let you "place and view" with AR

A solution that has emerged is a new style of exterior proposal using AR (augmented reality) display. With AR technology, you can use a smartphone or tablet to "try placing" virtual exterior components on the real site through the device screen. Gate posts, fences, plants, and garden lights appear composited into the camera view as if they actually exist there.

With this "place and view" proposal, homeowners can hold a smartphone over their own yard or parking area and check various design options in real time. Instead of imagining in their heads, they can see and compare on the spot, making it easier to intuitively choose a plan that feels right. For example, if you're torn between gate-post design A and B, you can display each in AR in front of the actual entrance to compare how they harmonize with the building and how their heights look. Textures and presence that are hard to judge from catalog photos or drawings can be confirmed at actual scale, greatly easing homeowner uncertainty.

Another benefit of AR proposals is that the homeowner can experience the evaluation process firsthand. Traditionally, homeowners only "viewed" plans presented by designers, but with AR they can move the smartphone themselves and freely check perspectives like "How does it look from this viewpoint?" or "What will it feel like when the gate is opened?" The "place and view" process elevates the homeowner from a passive observer to the main participant in plan creation, guiding them to a satisfying choice.

Specific examples of proposals visible with AR: gate posts, lighting, plantings, carports…

What kinds of exterior elements can actually be previewed on site with AR? Here are some specific proposal examples using AR displays.

• Gate posts and gates: The gate area, which can be considered the face of the house, can change impression dramatically depending on design and height. Displaying gate posts or gates in AR allows you to check their balance with the building and walls on site. If the gate post has nighttime lighting, you can even simulate how the lights look after dark.

• Fences and walls: Privacy fences and boundary walls can be confirmed in AR at actual length and height. Since you can assess how the view from the garden changes and whether the height is sufficient on site, you can reduce later regrets like "A slightly lower height would have felt less oppressive."

• Approach and paving: The shape and width of the approach to the entrance and the design of paving stones can be overlaid onto the ground in AR. You can check whether a curved path complements the garden or whether the flow from the parking area is smooth, using real dimensional perception. This lets you verify in advance the risk of feeling "hard to walk on" or "too narrow" after completion.

• Plantings and specimen trees: Plant and tree placement requires consideration of future growth. AR can visualize the height and volume after the chosen species grow. You can decide species and placement while checking how a tree looks from the living-room window and how sunlight and shadows fall. The overall impression the greenery gives to the garden is immediately obvious with AR.

• Carports and garages: Because garages and carports are large structures, it's important to grasp their presence beforehand. AR display of a carport on site lets you confirm whether the roof height or pillar positions will interfere with parking, and how well the structure harmonizes with the building façade. By simulating parking, you can also check door opening clearance and the circulation for exiting the vehicle.

As shown above, this method's strength is that every exterior element—from gate posts to plantings and parking equipment—can be reproduced on site in AR and evaluated. Details and overall cohesion that were unclear on paper become concrete when you view life-size images on site. This enables homeowners to choose plans while vividly imagining their "post-completion lifestyle," leading to highly satisfying exterior design.

The value of "non-shifting AR" achieved by LRTK’s high-precision positioning

For AR-based exterior proposals to be used with confidence, the positional accuracy of the displayed 3D models is critically important. Conventional smartphone AR recognizes the surroundings using camera images and the device's sensors, but when aligning in wide outdoor spaces small errors or shifts can occur. If a model is off by several tens of centimeters (several dozen inches) when displaying a plan across an entire yard, accurate image confirmation becomes impossible.

This is where LRTK's centimeter-level high-precision positioning demonstrates its power. LRTK leverages satellite positioning technology called RTK-GNSS and is a next-generation surveying system that can determine position with errors down to a few centimeters (a few inches) on a smartphone. While standard GPS is said to have errors on the order of several meters (several feet), LRTK achieves high on-site positioning accuracy by attaching a dedicated device to the smartphone and using correction information. By combining this high-precision positioning with AR display, you can overlay virtual models onto the actual site with pinpoint accuracy.

The value of high-precision, "non-shifting AR" is immeasurable. Homeowners gain the reassurance that the AR display in front of them shows the exact position and size of the final construction. You can accurately check details such as "Does this gate post extend beyond the property boundary?" or "Is the distance between the carport pillar and the house wall as shown on the plans?" Whereas conventional AR often provided only a rough guideline of "around here," LRTK allows placement with errors of just a few centimeters (a few inches) or less, so the layout shown on site matches the drawings.

Also, because the AR display remains stably non-shifting, long review sessions and whole-site inspections can be performed without stress. In typical AR, model positions can drift and require readjustment after changing viewpoint or time passing, but models fixed by LRTK position information stay correctly placed no matter how the homeowner walks around and views them from various angles. This technical reliability brings additional peace of mind and trust to both homeowners and proposers, leading to the conviction that "it will be built just as we saw it in AR."

Meetings with customers change! A proposal style experienced on site

AR + LRTK exterior proposals fundamentally change the meeting process with clients. Traditionally, exterior meetings involved spreading drawings and catalogs in an office or showroom and sometimes explaining with perspective drawings. With this technology, the style shifts to bringing clients to the actual site (in front of their house or in their yard) and letting them experience the proposal on a smartphone.

For example, a designer or sales representative visits the client's home and, while showing the AR screen on a smartphone, says in real time, "If we install a fence here 1.2 m (3.9 ft) high, it will look like this," or "Changing the gate post to a stone finish changes the impression like this." The client sees a life-size image and can immediately give candid feedback or request, "I'd prefer it a little lower after all." The representative can instantly revise the plan and show it again in AR—this makes it possible to build the plan together on the spot.

By incorporating on-site AR experiences, client understanding and satisfaction increase dramatically. There is no need to rely on imagination, so explanations can be shorter and still effective, and the elimination of "post-completion surprises" strengthens trust. For clients, being able to confirm plans on the real canvas of their home makes it easier to concretely envision their new life and more exciting. For proposers, being able to adjust proposals on the spot while receiving reactions reduces later rework and the number of meetings, improving efficiency. As the saying goes, seeing is believing: the process of showing and convincing evolves the traditional explanation-led negotiation into a more effective form.

Smoother design, sales, and construction: data sharing with LRTK Cloud

Using AR for exterior proposals not only deepens homeowner understanding but also positively impacts internal workflows and construction scheduling for proposers. LRTK includes cloud integration (LRTK Cloud), allowing data collected on-site and plans created there to be immediately saved and shared in the cloud. This enables designers, salespeople, and construction staff to share the same information in real time.

Concretely, the following benefits can be expected:

• Designers: The 3D models and layout information used for AR proposals on site are saved to the cloud, reducing the need to recreate drawings after returning to the office. Details of the plan the homeowner chose on the spot (gate-post position, height, materials, etc.) remain as data, preventing record or transmission errors and smoothing incorporation into design documents.

• Sales representatives: With the latest plan information always available in the cloud, sharing meeting contents and handing over clients becomes easier. For example, when a homeowner later asks a question, the sales rep can immediately refer to AR screen captures or dimensional data shown on site, enabling accurate follow-up. Consistent information management from proposal to contract leads to improved customer service quality.

• Construction teams: Using the high-precision surveying data and confirmed plan position information obtained with LRTK, on-site marking (layout staking) can be expedited. Because staking and equipment placement can be performed exactly where agreed with the homeowner, misunderstandings like "the installed position differs from what we were told" are less likely. Accessing cloud information also allows construction teams to understand the intended finished image and design intent in advance, facilitating smoother work planning. As a result, design, sales, and construction can operate as an integrated team, improving overall efficiency and quality.

Moreover, data accumulated on LRTK Cloud is useful for future maintenance and renovation planning. Even after completion, if you lack drawings or need to consult the original person in charge, you can access the cloud to confirm the surveying data and the positions of installed items. By establishing this information-sharing infrastructure, all processes related to the exterior become seamlessly connected, enabling a reassuring service for both homeowners and contractors.

Conclusion: The era of exterior proposals that "show and convince"

From an era of relying solely on drawings to an era of showing life-size finished images to gain agreement—exterior proposals are undergoing a major transformation. Visualizing exterior plans with AR + LRTK not only removes homeowner anxiety and increases satisfaction but also revolutionizes proposers’ workflows and construction accuracy. By having technology firmly support parts that were previously left to the homeowner's imagination, we can reduce regrets like "This isn't what I wanted" and increase delight in "I'm glad we had this done!"

Exteriors influence a home's impression and daily life satisfaction, so adopting AR as a powerful visual tool in the proposal process is likely to become the new standard. In fact, advanced exterior contractors and homebuilders are beginning to use AR simulation as a sales tool to differentiate themselves. AR proposals that embody the phrase "seeing is believing" will increasingly be recognized as an approach that builds stronger trust with homeowners and maximizes the value of exterior work.

We, too, want to realize happy exterior design for both homeowners and proposers through the latest "show and convince" proposals. If you are involved in exterior planning, why not consider the benefits of AR visualization so you don't miss this new wave?

Bonus: Smartphone surveying and AR exterior proposals with LRTK

You may be interested but think, "High-precision AR sounds specialized and difficult." However, with LRTK you can intuitively perform surveying to AR display using only a smartphone. Attach the dedicated compact receiver "LRTK Phone" to an iPhone or iPad and launch the LRTK app to complete setup. Then follow on-screen prompts to measure points or load design data from the cloud for AR display—the site itself becomes the stage for proposals.

Traditionally, surveying with centimeter-level accuracy (cm level accuracy (half-inch accuracy)) required specialized surveying equipment and skilled technicians, but LRTK automates difficult operations in the app and provides a user interface anyone can use. The ability to start easily on a smartphone without expensive equipment is another appeal. For example, designers and exterior planners who adopt LRTK can survey the site themselves and immediately provide AR proposals, dramatically increasing proposal speed. For homeowners, seeing a concrete vision from the first proposal makes a big difference in peace of mind.

Thus, smartphone surveying + AR proposals using LRTK are becoming a new standard in the exterior industry. Please take advantage of the benefits produced by high-precision positioning × AR to realize exterior plans that put smiles on both homeowners' and proposers' faces.
