Fans of Henrybuilt, which crafts made-to-order systems for wardrobes, bathrooms, laundry rooms, offices and walls, might want to check out its sister company, Space Theory, when it comes to Marin next month.

Space Theory will be located in a separate 4,000-square-foot building next to Henrybuilt in Mill Valley, and is the first of five new Space Theory showrooms scheduled to open in the United States by the end of 2026.

The new Mill Valley showroom will showcase the company’s products, house a design studio and be open to the public.

Space Theory offers a complete system, including storage units, pulls, integrated lighting, modular interior accessories, countertops, backsplashes and sinks solely for the kitchen.

While Henrybuilt bills itself as “luxury-level” craftsmanship, Space Theory is billed as “premium quality” and offered at a lower price point. (Prices are listed on spacetheory.com .)

Their differences are explained by Space Theory’s proprietary software that streamlines the design and production of its kitchens, making it a simpler process and product range than Henrybuilt products, which are highly customizable, often with many handcrafted details and components.

According to a press release, Henrybuilt was the first American company to adopt the European system approach to kitchens, which is a complete solution to the traditional American parts approach, which requires pulling together many components — like cabinets, fronts, pulls, counters, lighting and appliances — from many different suppliers.

Although Henrybuilt and Space Theory are separate companies, their products are manufactured in the same Seattle shop by the same people.

According to Scott Hudson, the founder and chief executive officer of both Henrybuilt and Space Theory, separating the companies has been positive.

“As it has turned out, the two brands are extraordinarily sympathetic and reinforcing of each other,” he said in the press release. “Space Theory focuses on software automation and design efficiencies in ways that are not always possible or appropriate with Henrybuilt, which offers a more hands-on design experience. We have a growing number of clients who have chosen both Henrybuilt and Space Theory for their homes, and architecture and design firms know they have the operational backing of Henrybuilt when they work with Space Theory, even though it’s at a lower price point.”

• Details: Space Theory will be open from 11 a.m. to 5 p.m. weekdays starting Feb. 27 at 360 Miller Ave. in Mill Valley. Call 415-802-0901 or go to spacetheory.com/page/mill-valley . Free design consultations are from 2 to 4 p.m. Fridays.

Grow a green thumb

Gardeners who want to develop greener thumbs should check out Plantilio.com , an online resource that was established 27 years ago.

According to the company’s press release, the free rebranded site promises to give gardeners “everything they need to grow bountiful harvests of beautiful flowers, herbs and vegetables.”

Plantilio adds that, for beginner gardeners, it “helps by shortening the learning curve and taking the guesswork out of creating a beautiful garden from the initial life cycle creation to the first blooms.”

On the site, there’s a helpful propagation guide for plants, along with specific techniques for various propagation methods (for example: hardwood or softwood cuttings of deciduous plants, runners, corms, divisions and rhizomes).

There are guides for succulents, houseplants and repotting plants with helpful close-up photographs, along with companion planting guides.

Pruning guides cover techniques for pruning plants — such as euphorbia, bee balm, coneflowers, hellebores and many more — to keep the garden looking neat and healthy and make you look good, too. Skills are always in style.

Maybe you just want to learn about a specific plant. In the site’s plant section, it’ll display photos, care instructions, if it’s toxic to pets or people, wildlife value, tips on pruning and pest control, and links to a few varieties.

Enter your zip code and Plantilio will pull up a planting schedule with specific dates for herbs and vegetables.
