About Horizon Tŷ Preswyl

Mae Horizon yn dŷ unllawr â ffrâm bren wedi'i ddylunio ar gyfer byw cyfforddus yn y tymor hir. Mae bondo'r teras, to'r cartbort a waliau'r talcen yn rhannu'r un dyfnder gweledol, sy'n creu silwét syml a chlir. Mae dyluniad strwythurol gofalus yn cuddio'r holl golofnau mewnol o fewn y waliau, felly mae'r tu mewn yn parhau'n agored ac eang. Mae dwy ystafell wely, ystafell fyw, ystafell fwyta, cegin ac ystafell westeion yn cysylltu heb goridorau. Mae ffenestri mawr sy'n wynebu'r de yn agor allan i deras ac yn uno'r gofod dan do ac yn yr awyr agored. Cadwyd deunyddiau a lliwiau i'r lleiafswm.

Design Challenge: To achieve a beauty that is both simple and striking, the palette of materials and colours was intentionally kept to a minimum, both inside and out. The plan is organised around a clear and efficient circulation, allowing daily life to unfold naturally and without stress. Designed from a long-term perspective, the house supports comfort and ease as its residents grow older, offering a timeless living environment that will remain graceful for decades to come.
Research: The large south facing sash windows connect seamlessly to the spacious outdoor terrace, creating a rich living space where the indoors and outdoors merge as one. The facade, which serves as the building’s face, has been designed with meticulous calculations of vertical and horizontal balance to achieve a form recognised as universally beautiful.
Inspiration: This is a project for a single storey timber framed house. Designed under the philosophy of a timeless design that will never look dated, even decades from now, it achieves a beauty that is both simple and striking, capturing the hearts of all who see it.
By eliminating all superfluous elements, this design exudes a timeless beauty that will continue to be cherished for generations to come.
Project Duration: Project Duration : From June 2018 to February 2025 / Project location : Tokyo(Japan)
Operation Flow: The plan comprises two bedrooms, a living room, dining room, and kitchen, together with a guest room, dressing room, bathroom, and toilet. The spaces connect seamlessly without relying on corridors, creating a circulation plan that is both simple and highly efficient. Furthermore, through meticulous structural design, all interior columns are concealed within the walls, allowing for a spacious and open plan interior.
