Anvitam | Sustainable Architecture & Ecological Design Studio

Anvitam is a sustainable architecture and ecological design studio based in Vadodara, Gujarat. Led by principal architect Archana Gavas, we design zero-carbon farm retreats, eco-resorts, food forests, and wellness sanctuaries globally, blending permaculture and biophilic design to restore ecosystems.

Regenerative Architecture & Permaculture Masterplanning

Our architectural studio integrates natural building materials, climate-resilient engineering, and syntropic agroforestry to construct buildings that work with nature. We believe in designing projects that restore local ecosystems rather than depleting them. From greywater recycling systems and passive solar cooling to vernacular earth construction, our design solutions are tailored to local climates, local materials, and traditional wisdom combined with modern engineering.

Permaculture Design & Consultation Services

We provide full permaculture masterplanning for agricultural land, eco-communities, and private estates. Our designs optimize water resources, maximize soil health, and integrate edible landscapes using organic and regenerative principles. Our work ranges from backyard gardens in Gujarat to large-scale ecological masterplanning worldwide.

Sustainable Resort & Farm Retreat Design

We design boutique eco-resorts, wellness sanctuaries, and homestays that offer low-impact, high-experience stays. Our designs prioritize locally sourced stone, lime plaster, bamboo, and rammed earth to match the natural landscape. We collaborate with developers to construct resorts that generate zero waste, harvest 100% of rainwater, and run on solar energy.

Natural Building Craft & Vernacular Architecture

Anvitam is committed to reviving ancient Indian construction techniques, such as red oxide flooring, lime plaster, mud walls, and traditional terracotta tile roofs. We show how alternative building materials outperform modern concrete in keeping buildings cool, reducing carbon footprint, and enhancing occupant health and indoor air quality.

Syntropic Agroforestry & Food Forests

We design multi-layered food forests and syntropic agroforestry systems that provide organic food security and restore biodiversity. By replicating native forest structures, we create self-sustaining agricultural ecosystems that require minimal irrigation and zero chemical fertilizers.

Biophilic Design Philosophy & Archana Gavas

Led by principal architect Archana Gavas, Anvitam is built on the core philosophy of biophilic and regenerative design. We do not just build structures; we design environments that foster a deep connection between human occupants and the natural world. Our design workflow analyzes solar paths, local wind patterns, and hydrological maps of the site to craft spaces that remain naturally cool in hot summers and warm in winters, minimizing reliance on mechanical heating and air conditioning systems.

Vernacular Earth Building & Natural Plasters

We specialize in using locally sourced building elements like clay, straw, lime, stone, and bamboo. Our architecture studio actively replaces toxic industrial materials such as cement plasters and synthetic paints with breathable alternatives like lime plasters, mud renders, and natural oils. These materials are not only fully biodegradable but also regulate indoor humidity and air quality, creating healthier, non-toxic living environments for families and guests.

Global Eco Architecture Studio based in Nadiad & Vadodara

While our physical studio is located at Santram Mandir Road in Nadiad, Gujarat, we consult on sustainable developments, food forests, and eco resorts globally. Our diverse team works with farm owners, hospitality brands, and community organizations to bring permaculture and biophilic principles into mainstream commercial and residential developments. We believe that sustainable architecture is not a luxury, but a necessity for the future of our planet.

Why I Stopped Buying CenturyPly & Greenply Doors

Published on 15 July 2026 by Archana Gavas

An architect explains why she stopped specifying CenturyPly and Greenply doors and windows, what problems homeowners overlook, and better alternatives.

Why I Stopped Buying CenturyPly & Greenply Doors

Let me guess.

You picked your door wood because it "looked premium" in CenturyPly catalogue.

Why I stopped buying Doors and Windows From CenturyPly or Greenply

CenturyPly

Nobody told you it was going to swell shut every monsoon.

Nobody told you termites were going to eat through it in four years.

Nobody told you the wood that works perfectly in Shimla will fail completely in Kochi.

Here's the truth nobody in the furniture showroom will say out loud: there is no single "best wood" for doors and windows.

There's only the best wood for your climate, your budget, and your maintenance habits.

In this guide, I'm going to walk you through exactly how to pick the right wood, the way I do it for clients, not the way a salesman does it for a commission.

We'll cover:


  1. What actually decides whether a wood door lasts 5 years or 50
  2. Hardwood vs softwood, explained without the textbook language
  3. Best wood for doors and windows by climate like humid, dry, coastal, cold
  4. A worldwide wood comparison table (teak, oak, walnut, mahogany, acacia, mango, beech, maple, cedar)
  5. Termite and weather resistance, ranked honestly
  6. What it actually costs, and where people overpay
  7. How to care for the wood you already have


By the end, you'll know more about choosing door and window wood than most people who sell it to you. Let's go.

Key Takeaways (TL;DR)


  1. The single biggest factor in climate-appropriate wood selection is moisture movement, not looks or price.
  2. Teak is still the best wood for doors and windows in humid, coastal, and tropical regions because of its natural oils and termite resistance.
  3. Oak wood and maple wood perform better in cold, dry climates where teak's natural oils aren't even necessary.
  4. Hardwood vs softwood for doors isn't about "better or worse", as softwoods work fine for internal doors in dry climates; they fail fast in humid ones.
  5. Sustainable wood for doors and windows doesn't mean weaker wood. Acacia wood and mango wood are strong, renewable, and far cheaper than teak.
  6. The cheapest wood upfront is almost always the most expensive wood over 15 years, once you count warping, replacement, and repair.
  7. Ask about moisture content and seasoning before you ask about the species. A poorly seasoned teak door will still warp.


What Actually Decides the Right Wood?

Everyone starts by asking, "which wood looks best?"

Wrong question.

which wood looks best?

which wood looks best?

The right question is: how much does this wood move when the air around it changes?

Wood is not "dead" material. It's still breathing, years after the tree was cut. It absorbs moisture in humid air and releases it in dry air.

That constant swelling and shrinking is what warps doors, jams windows, and cracks frames.

So the real decision comes down to three things:


  1. Climate — how much humidity swing does this wood have to survive, season after season?
  2. Exposure — is this an exterior door taking direct rain and sun, or an internal door in a dry room?
  3. Maintenance appetite — are you someone who will polish and reseal wood every year, or someone who wants to install it and forget it?


Get these three right, and almost any wood will last decades.

Get them wrong, and even the most expensive teak door will crack.

The Honest Difference between Hardwood vs Softwood for Doors

People treat "hardwood" like a promise of quality. It isn't. It's just a botanical category.

Hardwoods (teak, oak, walnut, mahogany, mango, acacia, beech, maple) come from slow-growing, broad-leaved trees. Denser grain, more natural resistance to moisture and pests, heavier, and usually costlier.

Hardwoods (teak, oak, walnut, mahogany, mango, acacia, beech, maple)

Hardwoods

Softwoods (pine, cedar, fir, spruce) come from faster-growing conifers. Lighter, cheaper, easier to work with, and perfectly fine for dry-climate interiors but they generally need chemical treatment to survive humid or termite-prone regions.

Softwoods (pine, cedar, fir, spruce)

Softwoods

Here's the part nobody explains: softwood isn't automatically worse. Cedar, for instance, is a softwood, and it's still one of the best weather-resistant woods for windows in cold, dry climates because of its natural oils and rot resistance.

So "hardwood vs softwood for doors" isn't really the debate. The real debate is does this specific species suit this specific climate.

Best Wood for Doors and Windows by Climate

This is the section that actually saves you money. Skip it, and you're gambling.

1. Humid and Tropical Climates (Coastal India, Kerala, Southeast Asia, Florida, parts of Australia)

If you've ever asked which wood is best for doors and windows in a humid climate, the answer almost every architect will give you is teak.

Teak wood contains natural oils and silica that repel water and termites without any chemical treatment. It's dense, it barely swells, and it can sit in monsoon humidity for decades without rotting.

Teak wood

Teak wood

This is exactly why teak wood dominates the market for the best wood for doors and windows in tropical regions, from Kerala homes to Southeast Asian resorts.

Mahogany wood

Mahogany wood

Close alternatives: Mahogany wood (slightly less water-resistant than teak, but beautiful grain and good for both interior and exterior doors) and Sapele, a teak-like African hardwood increasingly used where teak has gotten expensive.

2. Dry and Cold Climates (North India, Central Europe, most of North America)

Here, moisture swing isn't the enemy, as the wood doesn't need heavy natural oils to survive.

Oak wood

Oak wood

Oak wood is the classic choice here. It's strong, holds paint and stain beautifully, and is widely available across Europe and North America.

Maple wood

Maple wood

Maple wood and beech wood are excellent for interior doors and window frames in dry climates, both machine well, take a smooth polish, and cost less than oak or walnut.

Walnut wood

Walnut wood

Walnut wood is the premium choice for statement front doors and furniture in these regions. Gorgeous dark grain, but it's an investment piece more than a practical everyday door wood.

3. Coastal and Salt-Air Climates

Sal wood

Sal wood

Salt air accelerates corrosion of hardware and speeds up wood degradation. Teak still wins here because of its oil content, but Sal wood (a strong, water-resistant Indian hardwood) is a solid, more affordable regional alternative.

4. Budget-Conscious, Any Climate

acacia wood

acacia wood

This is where acacia wood and mango wood come in. Both are fast-growing, sustainable, genuinely strong, and cost a fraction of teak.

mango wood

mango wood

They're not ideal for constant direct rain exposure without a protective coat, but for internal doors, window frames, and furniture, they're some of the smartest sustainable wood for doors and windows choices available today.

Notice the pattern: there is no single winner. Teak wins in humidity. Oak wins in dry cold. Cedar quietly wins where you'd never expect a softwood to win.

The "best" wood is the one matched to where it's going to live.

Which is the best Termite-Resistant Wood for Doors

If termites are your real fear and in most of India, they should be, here's the honest ranking:

Which is the best Termite-Resistant Wood for Doors

Which is the best Termite-Resistant Wood for Doors


  1. Teak — natural silica content makes it genuinely termite-resistant, not just termite-tolerant.
  2. Sal wood — a strong regional performer, especially for exterior doors.
  3. Mahogany — good resistance, especially when properly seasoned.
  4. Acacia and mango wood — moderate resistance; benefit hugely from a chemical borate treatment before installation.
  5. Pine and untreated softwoods — poor resistance on their own; almost always need chemical treatment in termite-prone zones.


If a supplier tells you any wood is "100% termite-proof," that's your cue to ask more questions, not fewer.

What Does the Right Wood Actually Cost?

Prices shift constantly, but as a general shape:


  1. Budget interior doors (pine, mango, treated softwood): lower end of the market, but expect a 10–15 year lifespan before real repairs.
  2. Mid-range (acacia, beech, maple): balanced cost-to-durability ratio, best for interior doors and window frames in moderate climates.
  3. Premium (oak, walnut, sal, mahogany): higher upfront cost, 30–50 year lifespan with basic care.
  4. Top-tier (teak): highest upfront cost, but often the cheapest option over 40+ years in humid climates, because it barely needs replacing.


Where High-End Homes and Builders Actually Use These Woods

teak front doors

Luxury coastal villas in Kerala and Goa still default to solid teak front doors, not because it's trendy, but because nothing else survives a monsoon that well without constant upkeep.

walnut front-door

walnut front-door

In colder markets across Europe and North America, oak and walnut dominate front-door specifications, which is partly for looks, but mostly because those species don't need heavy oil content to resist the local climate.

acacia wood

acacia wood

And increasingly, architects working on budget-conscious, sustainability-focused homes are specifying acacia wood and mango wood for interior doors and furniture, because they grow fast, cost less, and still perform well indoors.

If you haven't already, this is a good moment to read why I stopped recommending mainstream cement walls for most climates, or why sustainable bricks are quietly becoming the smarter first choice for new builds.

The Honest Downsides Because I'm Not Selling You Anything


  1. Teak is expensive, and genuine, well-seasoned teak is getting harder to source ethically. Always ask where it's from.


Teak

  1. Acacia and mango wood need a proper protective coat and occasional resealing, or they'll show wear faster than hardwoods like oak.

  1. Any wood, installed without proper seasoning, will warp regardless of species. Seasoning and moisture content matter as much as the species name.

  1. Softwoods like pine, left untreated, are a genuine termite risk in humid regions - don't use them for exterior doors in tropical climates no matter how tempting the price is.

  1. Sliding doors and large window installations put extra stress on frame wood — go a size class stronger than you think you need.

None of these are reasons to avoid wood. They're reasons to choose the right wood and install it properly.

How to Actually Take Care of Wood Doors, Windows, and Furniture

A Quick Word on Front Doors, Composite Doors, and Modern Alternatives

composite doors

composite doors

If you genuinely can't source or maintain solid hardwood, composite doors which are engineered from wood fibre, insulating foam, and a protective skin are a reasonable modern alternative for front door replacement, especially in colder climates where insulation matters as much as moisture resistance.

uPVC door vs traditional door

uPVC door vs traditional door

They won't have the same soul as a solid teak or oak door, but they solve the maintenance problem for people who want to install once and forget it.

For everything else like wood wall panels, outdoor furniture, kitchen furniture, office furniture, the same climate-first logic applies.

Match the wood to where it's actually going to live, not to what looks best in a showroom light.

Conclusion

Here's what I want you to walk away with.

Choosing wood for doors and windows was never supposed to be a "pick what looks nice" decision. It's a climate decision first, a durability decision second, and only then a design decision.

Teak vs Oak  vs mango wood

Teak vs Oak vs mango wood


  1. Teak earns its price tag in humid, coastal regions.
  2. Oak and walnut earn theirs in cold, dry ones.
  3. Acacia and mango wood earn their place as smart, sustainable choices when budget matters more than a 60-year lifespan.


None of these woods are "better" in isolation. They're better for a place. Match the wood to the climate, season it properly, maintain it honestly, and it will outlast the building trends around it.

If you're planning a build right now and aren't sure which wood actually suits your site, climate, and budget, send me your plans. I'll walk through it with you, one door at a time.

P.S. — If this changed how you think about wood, you'll probably feel the same way after reading why I stopped recommending mainstream cement walls for most Indian climates, or why more smart homeowners are quietly switching to green, sustainable compound walls instead of the default. Both follow the exact same logic as this article.
