deVol Simon Cox kitchen in a glasshouse addition

Why this glasshouse kitchen works

A glasshouse kitchen addition sounds like a dream until you remember basic science: glass can overheat, glare can fry your eyeballs, and winter can turn your breakfast nook into a refrigerated display case. The genius of this project is that it treats “pretty” and “practical” like best friends instead of rivals.

The result is a bright, garden-facing kitchen that still behaves like a real kitchenone where you can cook, host, spill something, wipe it up, and keep moving (instead of tiptoeing around like you’re in a museum).

It’s not just a sunroomit’s a working room

The space reads like a modern conservatory, but it functions like an everyday hub: a place to prep food, store essentials, seat guests, and connect the house to the outdoors. That’s the secret sauce: it’s designed for life, not just for photos.

Simon vs. Sebastian: the name confusion

Let’s clear up the bit that makes design nerds gently twitch: many people search for “deVol Simon Cox kitchen,” but the cabinetry line tied to this look is widely known as the Sebastian Cox Kitchen by deVOL. If you’ve been wondering whether Simon is a person, a place, or a particularly stylish sourdough starterwelcome to the club.

Here’s the takeaway: regardless of how the phrase is circulating, the defining traits stay the same. Think: textured wood fronts, a handcrafted feel, and a palette that looks both earthy and intentionallike someone with excellent taste made a mood board and actually followed it.

What makes the “Cox” look recognizable

• Visible wood texture (not glossy perfectionmore “touch me” than “don’t touch”)
• Moody, inky finishes paired with lighter natural tones
• Handmade-style details that feel collected over time
• Practical beauty: design features that also do a job

Anatomy of the glasshouse addition

The architectural move that makes this kitchen unforgettable is the glasshouse addition itself: a greenhouse-like extension that adds square footage without turning the home into a generic box. It’s the kind of addition that looks like it always belonged therejust… with better lighting.

Key architectural choices that matter

• Steel-framed glazing for crisp lines and a refined, industrial edge
• A strong “anchor” wall (in this case, a stone wall) to keep the room grounded
• Thoughtful proportions so the ceiling height and glass planes feel intentional
• Clear connection to garden views so the outdoors becomes part of the room

Without something solid and weighty, an all-glass space can feel like you’re floating in a snow globe. The stone element is what gives this kind of kitchen addition emotional gravityplus it’s a visual counterbalance to all that transparency.

Materials: concrete, copper, steel, and beech

The “deVol Simon Cox kitchen in a glasshouse addition” aesthetic is basically a four-material band that somehow never argues: concrete, copper, black steel, and pale beechwood. Each one brings something different to the party.

Concrete: calm, durable, and quietly dramatic

Concrete floors and countertops create a seamless, modern backdrop. In a glass-heavy room, concrete also acts like a visual “exhale”a steady surface that doesn’t compete with the garden views. Bonus: it’s extremely forgiving of busy life, especially when the kitchen doubles as an entertaining zone.

Copper: warmth without going “farmhouse sign”

Copper details are the cheat code for warmth. Used in small doseslike around finger pulls or hardware accentsit prevents the palette from feeling cold or overly industrial. It’s the design equivalent of adding a dash of chili flakes: you don’t want a whole spoonful, but you do want to notice it.

Black steel: structure and definition

Steel-framed windows and doors outline the glass like a crisp ink drawing. In bright spaces, black frames add definition and keep everything from blurring into one big “light blob.”

Beechwood: texture that reads as craftsmanship

Beechwoodespecially when used with a visibly textured finishadds the handmade, grounded quality that many modern kitchens lack. It’s also a smart match for a glasshouse addition: wood brings softness and tactility to a space that could otherwise feel all hard surfaces and reflections.

Comfort engineering: heat, glare, and real-life usability

A glasshouse kitchen addition can be heavenly… or it can feel like you’re sautéing onions inside a pair of sunglasses. Comfort comes down to three things: managing temperature swings, controlling glare, and handling humidity like an adult.

1) Temperature control without killing the vibe

The best glasshouse additions don’t rely on “hope” as the primary HVAC strategy. They consider orientation, shading, and thermal mass earlybecause glass can gain heat quickly and lose it just as fast.

• Shading matters: overhangs, taller side walls, exterior shades, or strategic plantings can reduce summer overheating.
• Thermal mass helps: materials like concrete can stabilize indoor temperatures by absorbing and releasing heat gradually.
• Radiant heat can be your best friend: underfloor heating is often used in glass-heavy rooms to keep winter comfort steady from the ground up.

2) Glare control (because you deserve to see your cutting board)

Window coverings are not a design failure. They are a design completion. If your glasshouse kitchen addition faces strong sun, plan for treatments that control glare and heat gain without blocking the view entirely.

• Solar shades for daytime glare
• Operable blinds or cellular shades for cold nights
• Exterior awnings or screens for the most effective sun control

3) Humidity and condensation: the unglamorous truth

Kitchens create moisture. Glass gets cold. Nature does the math. In a glasshouse kitchen, ventilation is non-negotiableespecially if you cook often, boil pasta like it’s your love language, or keep plants that transpire like they’re training for a marathon.

Practical moves include a high-quality range hood that actually vents outdoors, operable windows or vents for cross-breezes, andif neededa dehumidifier during shoulder seasons. The goal isn’t to eliminate humidity; it’s to keep it in a range where your glass doesn’t constantly look like it’s having an emotional moment.

Layout lessons: cooking + entertaining without chaos

This is where the project gets especially instructive for anyone dreaming of a glasshouse kitchen: the layout supports real hosting. The island isn’t just a “statement piece.” It’s a workhorse.

Design cues worth stealing

• An island parallel to the anchor wall creates a natural prep lane and a social lane.
• Storage where you need it (cookbooks, pantry, trash, dishwasher) keeps the workflow tight.
• “Hide the chaos” zones (tall pantry cabinets, integrated appliances) let the space look calm even when dinner is a full-contact sport.

If you entertain, the best layout trick is simple: give the cook a forward-facing position. Nobody wants to host a party while staring at a backsplash like it owes them money.

How to recreate the look in an American home

You don’t need a historic stone cottage (or a design-savvy mood board that lives on your dining table for months) to borrow this concept. You need a good plan, realistic expectations, and a willingness to solve the boring stuff so the pretty stuff can shine.

Step 1: Choose the right “glass room” type

• Three-season room: typically not fully insulated; great for mild climates or occasional use.
• Four-season room: insulated and conditioned; better for year-round kitchens or dining spaces.
• Solarium-style build: more glass coverage; gorgeous, but it demands serious performance planning.

Step 2: Borrow the palette, not the problems

Love the look of concrete? Greatconsider concrete-look porcelain for easier maintenance. Want the copper warmth? Use copper-accent hardware or a single feature element rather than turning your kitchen into a penny collection.

Step 3: Think like a building scientist (just a little)

The most stylish glasshouse kitchen addition is the one you can actually use in August and January. Plan for:

• High-performance glazing (and the right solar heat gain strategy for your climate)
• Exterior shading when possible
• A ventilation plan that accounts for cooking moisture
• Temperature zoning (so the glass room doesn’t bully the rest of your house)

Step 4: Make it feel “collected,” not cataloged

The deVOL-style charm that American design sites keep pointing to is the old-meets-new mix: vintage or unusual pieces layered into a functional kitchen. Think: a sturdy table instead of an oversized island, open shelves that hold real dishes, and lighting that feels like it has a backstory (even if you bought it last Tuesday).

Common mistakes (and how to avoid them)

Mistake 1: Too much glass, not enough strategy

More glass isn’t always better. If your addition is all glazing and no shading plan, you’re essentially building a very expensive toaster oven. Balance transparent walls with insulated surfaces where you can, and always think about the sun’s path.

Mistake 2: Forgetting the “kitchen” part

If your glasshouse kitchen looks beautiful but has nowhere for the trash, no pantry plan, and no landing space by the oven, it’s not a kitchenit’s a stage set. Work backward from daily routines (coffee, lunches, weeknight cooking) and build the layout for that.

Mistake 3: Underestimating cleaning and maintenance

Glass shows everything: fingerprints, pollen, rain spots, and that one mysterious smudge that appears the minute guests arrive. Choose finishes that can handle frequent wipe-downs, and accept that a glasshouse addition comes with a little more upkeep than a standard room. The view is the payoff.

Mistake 4: Ignoring condensation risk

Condensation is common in glass-heavy rooms when indoor humidity meets cold surfaces. The fix is usually a mix of better ventilation, steady interior temperatures, and humidity managementnot panic-buying replacement windows on a Tuesday night.

FAQ

Is a glasshouse kitchen addition energy efficient?

It can beif it’s designed with performance in mind. Orientation, glazing specs, shading, and insulation details matter. Without them, it may be less efficient than a conventional addition.

What cabinets give the closest “deVOL Cox” feel?

Look for cabinetry with visible wood texture, simple profiles, and hardware that feels substantial (brass, copper, blackened metal). The goal is “handcrafted character,” not high-gloss perfection.

Can I do this in a hot climate?

Yesbut shading is everything. Exterior screens, deep overhangs, and glazing optimized for solar control can make the space comfortable. Plan ventilation and cooling early.

What’s the best countertop choice for a glass-heavy room?

Concrete (or concrete-look materials) works well visually because it’s calm and matte. Quartz, porcelain slab, and honed stone can also work if they’re chosen to reduce glare and handle real kitchen use.

What’s the biggest “don’t”?

Don’t design a glasshouse kitchen like a sunroom and then expect it to behave like a standard kitchen. Treat it as a kitchen firstthen make it beautiful.

Real-World Experiences: Living With a deVol-Style Glasshouse Kitchen Addition (500+ Words)

Let’s talk about what happens after the photoshoot, when the applause dies down and somebody has to actually boil pasta in this glass-wrapped beauty. The day-to-day experience of a glasshouse kitchen addition is equal parts delightful andhow do we say this gentlyhonest.

First, the light. Morning coffee in a glasshouse kitchen hits different. Even on gray days, the room tends to feel brighter than the rest of the house, which can make it the default “where humans gather” zone. People often describe it as having a subtle mood-lifting effect, the way a sunny breakfast nook doesexcept dialed up, because you’re basically sitting inside the sunlight. Plants love it, too. If you’ve always wanted to keep herbs alive without performing daily rituals and apologies, this setup is your moment.

Second, the connection to the outdoors. A glasshouse kitchen doesn’t just give you a viewit makes weather part of the ambiance. Rain becomes background theater. Snow looks cinematic. A breezy day reminds you to secure your napkins before they attempt flight. And if you cook for friends and family, the garden backdrop instantly adds “effortless hosting energy,” even if you are, in fact, sweating and whispering “please brown faster” at a pan of onions.

Third, comfort is a relationship, not a one-time decision. On sunny winter days, the space can feel naturally warmsometimes surprisingly soespecially if you’ve got thermal mass in the floor or counters. But the flip side is summer. Without shading and ventilation, a glasshouse kitchen can heat up quickly. People who love these rooms long-term typically develop small habits: pulling shades during peak sun, cracking a vent window, running a ceiling fan, or timing heavy cooking for mornings and evenings in the hottest months. It’s not hard; it’s just… a lifestyle. (Like owning a white couch.)

Fourth, humidity management becomes part of the homeowner vocabulary. Kitchens create steam. Add plants and you’ve basically opened a tiny spa. The owners who feel happiest in glass-heavy additions usually have a strong vented range hood, some operable windows, and a plan for shoulder seasons when outdoor temps swing. If condensation appears, it’s often treated as a signal to tweak airflow and humidityrather than a full-blown emergency. In other words: you learn to respond like a calm adult, not like someone who just discovered water behaves like water.

Fifth, cleaning is the trade-off you knowingly accept. Glass shows everything. Pollen season will introduce itself. Rain may leave spots. And fingerprints will arrive like tiny unsolicited signatures from everyone who walks by. The good news? Many people find the maintenance predictable: a quick weekly wipe, a deeper monthly clean, and seasonal attention when weather changes. It’s more work than a regular room, but it’s not unmanageableespecially when you’re rewarded with a room that feels bigger than it is, brighter than it should be, and more connected to nature than most kitchens ever get.

Finally, the “deVol Cox” look itself tends to age well in daily life. Textured wood and warm metals don’t demand perfection; they handle wear gracefully. Matte surfaces show fewer smudges than glossy ones. And a kitchen that mixes vintage-feeling elements with modern performance often feels more personal over time, not lessbecause it invites real use. You can host, cook, and live in it without feeling like you’re constantly ruining the aesthetic. That, honestly, is the highest compliment a kitchen can earn.
