What's the Difference in terms of Site Development? ## Below we explore the differences between the products TestFit offers **For a detailed explanation, please take a look at the [product comparison](https://www.testfit.io/pricing?hsLang=en) page** --- ### Parking Solver If you are utilizing ***Parking Solver*** you will only have access to the presets seen below: ![](https://support.testfit.io/hs-fs/hubfs/image-png-Mar-11-2026-01-55-50-9590-PM.png?width=340&height=782&name=image-png-Mar-11-2026-01-55-50-9590-PM.png) It's very common to start a site with one of the following presets: - Surface Parking - Park  - Impervious Once the site is created with one of those base layers, a [Region](https://support.testfit.io/knowledge/fundamentals?hsLang=en#regions) or a [Space](https://support.testfit.io/knowledge/how-do-i-add-a-space-to-a-site-building/park/chalet/impervious-area-?hsLang=en) can be applied. ![RegionSpace1](https://support.testfit.io/hs-fs/hubfs/RegionSpace1.gif?width=670&height=377&name=RegionSpace1.gif)**You can create unlimited deals with these massing presets.  Take a look at [this article](https://support.testfit.io/knowledge/how-do-i-add-a-space-to-a-site-building/park/chalet/impervious-area-0?hsLang=en) for a detailed walkthrough on adding spaces to your site.** **The [Parking Solver Overview Article](https://support.testfit.io/knowledge/testfit-urban-planner-overview?hsLang=en) is a great resource as well** --- ### Site Solver You have the same mass based capabilities as seen above, until a ***Premium Preset*** is applied to a site or region. Make sure you have the ***Show premium presets*** option enabled: ![](https://support.testfit.io/hs-fs/hubfs/image-png-Mar-11-2026-01-57-03-1995-PM.png?width=332&height=102&name=image-png-Mar-11-2026-01-57-03-1995-PM.png) Once you select your preset, you will then be prompted  to use a credit. ![](https://support.testfit.io/hs-fs/hubfs/image-png-Oct-29-2025-06-28-40-6624-PM.png?width=327&height=163&name=image-png-Oct-29-2025-06-28-40-6624-PM.png)   The premium presets contain high detail attributes that allow for a more granular solve. **![](https://support.testfit.io/hs-fs/hubfs/image-png-Oct-29-2025-06-35-59-7656-PM.png?width=670&height=450&name=image-png-Oct-29-2025-06-35-59-7656-PM.png)** --- **For an in-depth look into the functionality of each typology, select it from the list below:** [Higher Density](https://support.testfit.io/knowledge/site-development?hsLang=en#higher-density) [Lower Density](https://support.testfit.io/knowledge/site-development?hsLang=en#lower-density) [Garden](https://support.testfit.io/knowledge/site-development?hsLang=en#garden) [Industrial](https://support.testfit.io/knowledge/site-development?hsLang=en#industrial) [Datacenters](https://support.testfit.io/knowledge/site-development?hsLang=en#datacenters) [Generative Design](https://support.testfit.io/knowledge/site-development?hsLang=en#generative-design) [Parking](https://support.testfit.io/knowledge/site-development?hsLang=en#parking) [Retail](https://support.testfit.io/knowledge/site-development?hsLang=en#retail) [Core-Based](https://support.testfit.io/knowledge/site-development?hsLang=en#core-based) -
