[Behind the Design] A Home That Grows With Your Family: Three Houses Designed Around How You Actually Live

A home that grows with your family — that's what we set out to design. Most architects design around square meters. We design around time.

How your mornings feel. Where your children will play at three years old, and where they'll study at fifteen. How the light should fall on a Sunday afternoon when you have nowhere to be.

These are three houses we designed for three very different families in Japan — and what each one taught us about what a home is really for.

── Modern Japanese House Design & Spatial Philosophy by Architectural Solutions Design Office (ASDO), an Architect Office Based in Tokyo. 

1. Two Brothers, One House — Bringing the Light Upstairs

Two brothers, both working full-time, came to us with a simple problem: their living room was dark.

The bedrooms upstairs had good southern exposure, but neither of them was home during the day. The light was going to waste. Meanwhile, the ground-floor living room — the place they actually used to relax on weekends — felt heavy and dim.

The answer was straightforward once we saw it: move the living room to the second floor.

We stripped the layout back to what they needed for their current lifestyle: two private bedrooms on the ground floor, a small Japanese-style tatami room, and a bright, open second-floor living space that catches the afternoon sun.

We also discussed the long-term reality upfront: stairs get harder as you age. However, considering the potential for this prime urban location to be rented or adapted in the future, they felt that prioritizing their daily comfort right now was the right choice. That clarity made it possible to design without compromise.

After moving in, they told us: "It feels completely different from anything we've lived in before."

2. A House for Slowing Down — Embracing "Shakkei" and Eye Levels Made for the Future

My client, retiring and relocating to the countryside to enjoy fishing, wanted something simple: a single-story house where life could finally slow down.

The site had a beautiful row of cherry trees along the river in front. We brought the traditional Japanese concept of Shakkei (borrowed scenery) into the design — a large, minimalist opening frames the trees like a living painting you interact with every day.

The guest room presented a different kind of design challenge. They wanted a traditional Japanese tatami space, but in a standard flat layout, someone sitting on the floor looks up at anyone sitting on a living room sofa or chair. The eye levels don't match, creating an awkward psychological distance.

Rather than converting it to a Western-style room, we raised the tatami floor to create a "koagari" (raised platform) that aligns everyone's eye level perfectly. We then carved out a horigotatsu (recessed footwell) beneath the built-in desk, so guests could sit comfortably without folding their legs. It was a small decision made with the next twenty years of comfort in mind.

"Design it however you think is right," they told us. "We want you to make something you're proud of."

We took that trust seriously.

3. A House for Right Now and Ten Years From Now — Fluid Spaces for a Growing Family

A young couple, their first child just born, came to us with a distinct rhythm of life. The mother worked from home, while the father often returned late from the office. What they needed was a house where she could work, cook, and keep an eye on the baby seamlessly, without constantly shifting between isolated rooms.

We solved it with precise sightlines.

By creating a raised tatami platform adjacent to the dining area, we designed a multi-generational hub. While the baby is small, this platform functions as a safe, enclosed daybed where the mother can watch over the infant directly from the kitchen, and the father can easily see them from the dining table.

As the child reaches three or four, the space transforms into an open stage, a fort, and a reading nook. The meaning of the space changes naturally as the child grows.

Furthermore, because the house sits right next to the husband's parents' home, we carefully designed the ground floor layout — how the garden connects, where the communal spaces sit — so that three generations can interact closely without feeling crowded. In ten years, the tatami platform can transition into a quiet study space, while the children take over the upstairs bedrooms. The house rearranges itself around a family that is still evolving.

A Home Is a Container for Time

What these three families have in common is that none of them asked us to design only for the immediate present.

They asked us to design for the life they were moving toward — the quiet Sunday mornings, the changing seasons, and the spaces that adapt as the years pass.

We are a licensed Japanese architecture office based in Bunkyo, Tokyo. We work fluently in both Japanese and English, and we bring advanced 3D visualization into every project from the very first sketch — ensuring you can experience and understand the space deeply before a single nail is driven.

How We Support Your Journey: 

• Free Online Consultation: We offer complimentary initial meetings via Google Meet for clients in Japan and worldwide.

• Early-Stage Land Consultation (Complimentary): No plot yet? Bring your potential land datasheets to our online meeting. While formal zoning and legal verification require site-specific structural surveys, we can offer architectural insights from a design perspective—helping you visualize how a potential space might flow before you make an offer.

• Bilingual Coordination: Seamless navigation through complex Japanese building codes and design choices in English.

  
  

Whether you already have a plot of land or are just beginning to explore possibilities over a cup of coffee, we would be glad to talk.
