ADU (Accessory Dwelling Unit) Real Estate Cost Calculator Website Template

Quick summary

Casita is a lead generation landing page template designed for ADU builders who convert garages, guest houses, and vacant lots into income-producing dwellings. It leads with a live ROI calculator, guides visitors through three escalating project showcases in a zigzag gallery layout, and closes with a focused lead capture form. The editorial warmth of the Sunset Mesa color system makes every section feel inviting and trustworthy.

Who this template is for

This template is built for service businesses in the ADU renovation and construction space. It speaks directly to the homeowners those businesses need to reach and gives the business a polished, credible first impression.

• ADU builders, contractors, and renovation crews offering garage, basement, or ground-up accessory dwelling unit conversions
• Real estate investors and small landlords evaluating the return on investment of a backyard dwelling conversion
• Homeowners with unused structures who need a clear picture of costs, rental income, and payback timelines before committing

What problem this template solves

Most homeowners with unused square footage feel stuck between curiosity and commitment. They want numbers before they talk to anyone. A generic contractor website gives them nothing concrete, so they leave.

• Visitors arrive unsure whether an ADU project will pencil out financially, and there is no quick way to find out
• The gap between a homeowner's vague idea and a contractor's first site visit is wide, and most prospects fall through it
• Project photos alone do not build enough trust; buyers need to see real build timelines, achieved rents, and client stories alongside the imagery

What you get with this template

This template delivers a fully structured, single-page layout with every section pre-built and ready to customize. You get a visual flow that moves a first-time visitor from curiosity to a qualified lead without friction.

• A hero calculator section with animated estimate output, three zigzag project gallery sections, two full-width client quote bands, and a lead capture form with address input and goal selection
• An Atelier Studio visual identity using the Sunset Mesa color palette with Fraunces serif display type and DM Sans body type
• Scroll-triggered animation, a sticky bottom call-to-action bar, a marquee band, and a number counter animation built into the layout

Feature list

This template is built around interactivity and editorial presentation. Each feature below serves the core goal: turning a curious homeowner into a booked site walk.

Live ROI Calculator with Animated Output

The hero section centers on an interactive calculator titled "What's Your Backyard Worth?" Visitors enter their city, existing structure type, and approximate square footage. The tool returns a projected build cost range, estimated monthly rental income, and a payback timeline in months. Numbers animate in like figures being sketched onto vellum, anchoring expectations before the visitor scrolls.

Zigzag Project Gallery

Three completed projects are presented in an alternating left-right layout. Each section pairs a large luminous after-photo with a project story covering the original structure, scope of work, build timeline, and final rent achieved. The projects escalate in ambition from a simple garage conversion to a ground-up backyard build with a rooftop deck.

Full-Width Client Quote Bands

Narrow full-width bands appear between project sections. Each band displays a single client testimonial in terracotta italic type over a warm linen background. The effect mirrors gallery wall text and keeps social proof woven naturally into the scroll experience.

Sticky Lead Capture Call-to-Action Bar

After the first project section, a sticky bottom bar appears with the primary call to action "Get My ADU Estimate." It remains visible as the visitor scrolls, reducing the distance between intent and conversion at any point on the page.

Structured Lead Capture Form

The final section presents a "Book a Site Walk" form. It captures property address with auto-suggest input, structure type, the visitor's primary goal (rental income, family housing, or property value), and preferred contact method. The form feels like a natural continuation of the calculator rather than a cold sales ask.

GSAP ScrollTrigger Reveal Animations

Sections reveal as the visitor scrolls using GSAP ScrollTrigger. The animation cadence is deliberate and editorial, reinforcing the gallery walk creative direction without overwhelming the content.

Page sections overview

Design & branding system

The visual identity follows an Atelier Studio editorial direction. Every color, type choice, and spacing decision is built to evoke warmth, craft, and confidence, like a sketchbook left open on a worktable at golden hour.

• Sunset Mesa color palette: plaster white (#F5EDE3) as the dominant background, terracotta clay (#C4704E) for headings and primary buttons, charcoal drafting pencil (#3B3735) for body text, and pale desert sage (#B5BFA1) for tags, dividers, and hover states
• Backgrounds alternate between plaster white and warm linen (#EDE4D8) on every other zigzag section, keeping the eye moving without jarring contrast
• Typography pairs Fraunces serif for display headings with DM Sans for body copy and user interface elements, creating an editorial contrast that feels both refined and approachable

Mobile & speed optimization

The template is designed desktop-first to support the calculator interaction, with a fully responsive layout that adapts cleanly to tablet and mobile screen sizes.

• Static sections use server components to keep the initial page load light, while the calculator and sticky call-to-action bar load as client components
• The zigzag gallery stacks vertically on smaller screens, keeping project stories and photos readable without horizontal scrolling
• Scroll animations and the sticky bar are built to function correctly across device sizes, maintaining the intended experience on mobile without breaking the layout

How this template helps you convert

Every section in this template is sequenced to move a visitor one step closer to submitting their contact details. The page does not rush the ask; it earns it.

1. The hero calculator delivers instant, personalized numbers that replace vague anxiety with concrete possibility, making the visitor invested before they read a single project story
2. The escalating project gallery builds credibility progressively, each section adding more ambition and more proof, so by the third project the visitor already feels confident in the builder's capability
3. The sticky call-to-action bar and the closing lead form work together to capture intent at two different moments: the impulse decision mid-scroll and the considered decision at the end of the page
