## Insights
- [What a home renovation costs in Bangkok](https://8kunya.com/insights/home-renovation-cost/): A full renovation of a Bangkok condominium or house costs between ฿15,000 and ฿30,000 per square metre in 2026, so ฿1.2 – 2.4 million for an 80 m² unit. A kitchen alone runs ฿250,000 – 800,000, a bathroom ฿150,000 – 450,000. Work takes six to twelve weeks on site, plus two to four weeks of building permissions. The single biggest cost driver is joinery, then stone, then how much of the electrical and plumbing has to be replaced.
- [What interior design costs per square metre in Bangkok](https://8kunya.com/insights/interior-design-cost-per-sqm/): In Bangkok in 2026, interior design alone costs ฿1,000 – 1,500 per square metre for a full set of drawings and material boards. Design and build together, with the studio constructing what it draws, costs ฿12,000 – 28,000 per square metre for a condominium, ฿15,000 – 35,000 for a house, ฿9,000 – 18,000 for an office and ฿20,000 – 45,000 for a restaurant. A 75 m² condominium designed and built in the middle of its range costs about ฿1.5 million.
- [How to lay out a bedroom that actually works](https://8kunya.com/insights/bedroom-layout/): A bedroom works when there is 60 cm of clear floor on the sides of the bed you get out of, 70 cm in front of a wardrobe so the doors open, and the bed does not face a door that opens straight onto it. In a 10 m² Bangkok condominium bedroom that means a 5-foot bed against the long wall and a 60 cm deep built-in wardrobe on the wall opposite the window. From 14 m² a 6-foot bed with two bedside tables fits; from 20 m² a walk-in wardrobe or a desk becomes possible.
- [Designing a Buddha room or prayer shelf in a condominium](https://8kunya.com/insights/buddha-room/): A Buddha room or prayer shelf should face east or north, sit against a solid wall rather than under a beam or opposite a bathroom door, and stand higher than the head of anyone seated in the room. In a condominium the studio usually builds a niche 60 – 120 cm wide and 35 – 45 cm deep at a height of 150 – 170 cm to the shelf, with a warm light above. A built-in prayer niche costs ฿35,000 – 120,000; a separate Buddha room of 4 – 6 m² with joinery and lighting costs ฿180,000 – 450,000.
- [Fitting out a new condominium in Bangkok: what to do first](https://8kunya.com/insights/condo-fit-out/): Fitting out a new Bangkok condominium takes four to six weeks of design and six to ten weeks on site, and costs ฿12,000 – 28,000 per square metre for design and build, or ฿8,000 – 15,000 per square metre if the developer's kitchen and bathrooms are kept and only joinery, lighting and finishes are added. Do the ceiling, lighting and electrical points first, then built-in wardrobes and the kitchen, then floors and paint, then loose furniture. Changing electrical points after the joinery is in is the most common and most expensive mistake.
- [Renovating an older condominium: costs, permissions and what to expect](https://8kunya.com/insights/condo-renovation/): Renovating a Bangkok condominium costs ฿15,000 – 30,000 per square metre for a full strip-out with new electrics, plumbing, wet areas and joinery, and takes six to twelve weeks on site after two to four weeks of juristic office permissions. In a unit older than twenty years expect to replace the electrical board and circuits, the water pipes and the bathroom waterproofing, whatever else is done; these three items cost ฿250,000 – 450,000 for an 80 m² unit and are the reason a cheap renovation is a short one.
- [Office interior design in Bangkok: space per person, cost and timeline](https://8kunya.com/insights/office-interior/): A Bangkok office fit-out costs ฿9,000 – 18,000 per square metre in 2026 for design and build including partitions, ceilings, lighting, flooring, power and data, meeting rooms and a pantry; loose furniture adds ฿15,000 – 40,000 per workstation. Plan 8 – 10 m² per person in open plan and 12 – 14 m² per person once meeting rooms and a pantry are included. A 300 m² office for 25 people takes four to six weeks of design and six to eight weeks on site, so sign the lease with at least three months before the move.
- [Restaurant design in Bangkok: seats per square metre, cost and how fast it can open](https://8kunya.com/insights/restaurant-design/): A restaurant in Bangkok seats roughly one cover per 1.2 – 1.6 m² of front of house for casual dining and one per 1.8 – 2.2 m² for fine dining, with the kitchen and back of house taking 30 – 40 percent of the total area. Front-of-house design and build costs ฿20,000 – 45,000 per square metre in 2026, the kitchen fit-out ฿12,000 – 25,000 per square metre plus equipment, and a bar counter from the atelier ฿150,000 – 600,000. A 200 m² restaurant takes six to ten weeks on site if every finish is fixed before demolition; Prego opened in one month.
- [Built-in furniture in Bangkok: what it costs per metre and how to specify it](https://8kunya.com/insights/built-in-furniture-cost/): Built-in furniture in Bangkok is priced by the linear metre of run, at full height. In 2026 laminate is ฿9,000 – 14,000 per linear metre, veneer or lacquer ฿16,000 – 28,000, and kitchen cabinets ฿14,000 – 26,000 including carcass, fronts and hardware but not stone or appliances. A television wall runs ฿80,000 – 300,000. Lead time is three to five weeks from approved drawings, and hinges and runners from Blum, Hettich or Häfele should be named in the quotation.
- [Partitioning a room in a Bangkok condominium: walls, glass, sliding screens and what each costs](https://8kunya.com/insights/room-partition/): Dividing a Bangkok condominium costs ฿3,500 – 7,000 per square metre for a gypsum wall on steel studs, ฿9,000 – 18,000 per square metre for framed glass, and ฿6,000 – 12,000 per linear metre for a timber slat screen. Allow a further ฿15,000 – 40,000 to carry air conditioning and lighting into the new room. Most juristic offices permit lightweight partitions but refuse blockwork, and a sealed new bedroom needs its own return air path or it will be uncomfortable.
- [A walk-in closet in a Bangkok condominium: minimum size, layouts and cost](https://8kunya.com/insights/walk-in-closet/): A walk-in closet needs 1.5 m of width for a single-sided run and 2.1 m for a double-sided one, both with a clear aisle of at least 90 cm. Hanging rails sit at 1.05 m for shirts and 1.75 m for long items, and a wardrobe needs 60 cm of internal depth. In 2026 the joinery costs ฿9,000 – 14,000 per linear metre in laminate and ฿16,000 – 28,000 in veneer or lacquer, so a 6 m double-sided closet is ฿54,000 – 168,000.
- [Extending a house in Bangkok: rear kitchen extensions, permits, structure and cost](https://8kunya.com/insights/home-extension/): A rear kitchen extension of 12 – 20 m² is the commonest house extension in Bangkok. Structure on its own micropiles costs ฿15,000 – 25,000 per square metre, and fit-out a further ฿15,000 – 35,000 per square metre, so ฿400,000 – 1,000,000 for a 16 m² room. Anything above 5 m², or any work touching the structure, needs a permit under the Building Control Act; allow ninety days. A wall with openings must sit 2 m from the boundary.
- [Designing a kitchen in Bangkok: layout, ventilation, materials and cost](https://8kunya.com/insights/kitchen-design/): A Bangkok kitchen usually works as two rooms: a Western kitchen open to the living space, and a Thai kitchen behind it that takes the heat and the smoke. Cabinets cost ฿14,000 – 26,000 per linear metre in 2026, a quartz worktop ฿4,500 – 9,000 per metre and sintered stone more. Allow 90 cm between runs in a galley and 100 – 120 cm around an island. In a condominium plan the hood first, because most buildings forbid a new duct through the façade.
- [Designing a café in Bangkok: seats per square metre, counter flow, cost and opening date](https://8kunya.com/insights/cafe-design/): A Bangkok café seats one customer per 1.5 – 2.0 m² of front of house, so a 100 m² shop with 65 m² of seating takes 32 – 43 covers. Fit-out costs ฿20,000 – 45,000 per square metre in 2026, plus ฿400,000 – 1,200,000 of equipment. A two-group espresso machine needs its own 20 A circuit and softened water. Six to ten weeks on site is realistic, and the licences should run in parallel with the build, not after it.
