+# Version 008 — licensed Tesla and daylight walkthrough
+
+15 September 2026. Marcus selected the existing Tesla Model 3 by 7K Studio, then asked for more sunlight to walk around in daylight.
+
+The licensed model replaces the handmade Model Y-inspired placeholder in a private Blender revision and the whole-site Unreal prototype. The original artist geometry, interior, wheels and shaders are retained in Blender, with a simplified fast display. All 31 tour chapters match v007. Unreal uses the reduced artist geometry and adapted PBR materials, with slot assignment by imported material name. A simple car collision box blocks walking; eight floor traces and normal entry movement passed.
+
+Unreal daylight uses a higher neutral sun, brighter sky, reduced native fog and adaptive exposure. Inspection found the old Blender haze volume had imported as an opaque enclosing cube, blocking sunlight and the sky. That non-colliding export was removed; Unreal's native atmosphere/fog now handle the environment. The sun also pointed upward because of positional Rotator argument ordering. An explicit look-at rotation now points the sunlight downward from the northeast, at approximately 52.5 degrees elevation; its forward vector was verified. Actual daylight captures were reviewed.

 ## Pending wall-integrated bed requirement

 A 11 September 2026 note requests that the bed be rigidly built into wall framing with a considered load path, quiet isolation and Eight Sleep access. This was recorded without a geometry edit in decisions/2026-09-11-bed-wall-integrated.md. The v007 presentation retains the current free-standing bed; incorporate the wall-integrated platform in the next bedroom design revision, with its fixings and load path still subject to engineering.

+<main><div class="intro"><p class="updated">Started September 2026 · Concept design · A project for the coming years</p>
+<h1>A home that can grow.</h1><p class="lede">A simple family homestead in Samford Valley, Queensland. Warm timber, soft clay walls, solar power, food gardens and room to change my mind.</p>
+<p>I want to spend the next few years getting this house right. Inspired by Derek Sivers’ article <a href="https://sive.rs/fit">Building without predicting</a>, the starting point is a few straightforward spaces, with future additions left visible as outlines. The house should adapt to life as it unfolds.</p>
+<blockquote>“All buildings are predictions. All predictions are wrong.”<cite>— Stewart Brand</cite></blockquote>
+<p>The current model brings together a central kitchen, dining and living space, an adjacent parents’ bedroom, a quiet meditation room, an outdoor sauna and shower, and a garage with a workbench and bike storage. Container-enclosed rainwater storage, solar panels, a greenhouse and garden beds are part of the homesteading idea.</p></div>

+<div class="intro"><h2>Space for everyday life</h2><p>The plan brings together a covered place to train, an outdoor table for ten, a shared oval garden and gently curving walks ending at a quiet bench. The former table-tennis deck has become a flowering garden. A clear breakfast counter, pantry and freezer storage, and a garden harvest bench make everyday food preparation easier.</p><p>A separate 10 × 10 metre area is reserved for basketball later. It is shown as a dashed outline on the plan; the court surface and hoop have not been built into the concept. The future dwelling spaces also remain outlines.</p><p>The Blender inspection tour has 31 chapters and lasts 2 minutes 35 seconds, with updated views of the garden layout, future pavilions and kitchen.</p></div>
+<div class="intro"><h2>Where the project goes next</h2>
+<p>The Blender house is the working concept, now accompanied by a short presentation film and a walkable whole-site Unreal prototype. The next step is to refine that prototype for a smooth, packaged client experience.</p>
+<ol class="roadmap"><li><strong>Keep refining the house.</strong> Test room proportions, circulation, materials, storage and where future buildings belong.</li><li><strong>Bring in the real site.</strong> Add boundary and contour surveys, site photographs and LiDAR when a property is available.</li><li><strong>Develop coordinated plans.</strong> Bring architectural, structural and services models together with the landscape and access design.</li><li><strong>Develop the Unreal experience.</strong> Refine materials and performance, add interactions and camera tours, then package and test the walkthrough for clients.</li><li><strong>Record the build.</strong> Keep dated decisions, construction photographs and revised models as the house becomes real.</li></ol>
+<p><a href="images/concept-site-plan.svg">View the updated concept site plan &rarr;</a></p>
+<p class="note">These images are early design studies. The terrain is illustrative; surveyed land, LiDAR and construction drawings have not been added yet.</p>
+<h2>Tesla and a daylight walkthrough</h2><p>15 September 2026 — The garage now uses an existing Tesla Model 3 by <a href="https://www.blendkit.com/asset-gallery-detail/1fc56739-2fd9-447e-b2c1-fee5d9e276b7/">7K Studio</a>. The Unreal walkthrough has clear daytime lighting. The licensed scene is stored privately; the public repository retains the earlier distributable model. The film above remains version 007.</p><figure><a href="images/v008-tesla-garage.png"><img src="images/v008-tesla-garage.png" alt="7K Studio Tesla Model 3 in the timber and clay garage, rendered in Blender" width="1600" height="1000" loading="lazy"></a><figcaption>The imported artist model in Blender, with the existing workshop and bikes.</figcaption></figure><figure><a href="images/v008-daylight-overview.png"><img src="images/v008-daylight-overview.png" alt="Actual Unreal Engine daylight view of the homestead" width="1600" height="900" loading="lazy"></a><figcaption>Actual Unreal Engine daylight scene. Walking and Tesla collision have been tested.</figcaption></figure><h2>Project journal</h2><p><strong>12 September 2026 — Presentation and walking prototype.</strong> Refined the Blender scene, created a short client concept film and imported the full site into Unreal Engine with a walking character, collision and lighting. This is an evolving design study; the Unreal project is not yet a packaged client application.</p><p><strong>10 September 2026 — Garden Buddha.</strong> Added a seated stone Buddha beside the meditation pavilion and a 31st tour chapter. The updated Blender model, plan, render and design context are saved in the public project repository.</p><p><strong>10 September 2026 — Container water storage.</strong> Replaced the exposed water tanks with a dark-green container-style enclosure, updated the service path and tour, and added exterior and cutaway renders. The <a href="https://git.rehbock.xyz/marcus/samford-valley-home">project repository is now public</a>, including Blender models, design context and revision history.</p><p><strong>10 September 2026 — A home held together by its garden.</strong> Removed the table-tennis deck, aligned the pavilions and added an oval garden court, curved covered breezeway, smooth paths and thirteen flowering beds. Updated the camera tour and saved the design history, Blender models and supporting files in a private Git repository.</p><p><strong>10 September 2026 — Movement, meals and a detailed kitchen.</strong> Added the training area, ten-place outdoor table and tea counter, table tennis, a future basketball reserve, garden walking loop, quiet bench and convenient food storage. Refined the kitchen with an oven, induction, copper cookware and a marble island. Updated the site plan and saved the 30-chapter Blender tour as milestone v003.</p><p><strong>10 September 2026 — Bedroom comfort.</strong> Added an Eight Sleep-style bed-cooling system, blackout curtains and air conditioning. The updated Blender tour opens in the bedroom; the curtains have a saved closed position for night-time studies.</p><p><strong>10 September 2026 — First saved milestone.</strong> Full Blender homestead and two-minute camera tour; a reading corner with 163 books; a solar-powered garage study; and the first actual Unreal Engine meditation-room render. Working files and a dated snapshot are stored on my server.</p>
