【Full house renovation project schedule, budget and process reference】
Share
Hong Kong's whole-home renovation projects involve a wide range of projects, with no standardized timeline, budget, or process. A full-home renovation typically involves multiple stages, including demolition, plumbing, plastering, carpentry, painting, custom-made furniture, and final inspection. The duration and budget vary depending on the unit size, design requirements, and quality of materials used. The average reference price for renovations in Hong Kong for 2024-2025 is approximately $1,000 per square foot, with actual prices fluctuating between $600 and $1,200. This includes not only construction fees but also project management costs. Construction times range from as fast as 40 days for smaller units to three months or more for larger ones.

A 300-square-foot home typically consists of a one-bedroom apartment. Whole-house renovations or renovations typically focus on organization, practicality, and simplicity. Renovation procedures include complete removal of existing renovations, wall and floor leveling, plumbing and electrical wiring repairs, basic plastering repairs, painting, and simple carpentry. The budget is approximately $150,000-$180,000, with custom furniture costing a minimum of $40,000-$60,000. A typical construction period is approximately 1-1.5 months. Design details such as open kitchens, hidden storage, and fold-out beds can be added to the budget to avoid overspending on the total cost due to upgrades.

400 square feet is common in one- to two-bedroom units in urban areas. The renovation process and projects include demolition, re-installation of plumbing and electrical appliances, whole-house plastering, tile laying, upgrading doors and windows, kitchen and bathroom renovations, painting, cabinet making, home lighting installation, etc. The budget fluctuates from $250,000 to $320,000, depending on the materials used and the complexity of the design. The market usually costs around $300,000 or more (including custom-made furniture and high-end materials, it reaches $360,000-$380,000). The construction period is generally 45-70 working days (2-2.5 months). The shortage of custom-made furniture or bricks may delay the construction.

A 600-square-foot apartment is a mainstream unit for mid-sized families, offering a wide range of renovation options. The design allows for separate living rooms and bedrooms, and the kitchen and bathroom layouts can be significantly modified. The typical budget is $380,000-$580,000, which can increase due to window additions, partition changes, and custom furniture installations. Typical quotes include plastering costs of $80,000-$100,000, plumbing and electrical work starting at $70,000, custom furniture starting at $100,000, and painting starting at $30,000. The typical construction period is approximately 2-3 months, but the more complex the design and the higher-quality materials used, the longer the construction period.

Units over 800 square feet are often found in private buildings or duplexes, and the overall renovation is extensive. Medium to large-scale users prioritize design and zoning. Costs for full-house demolition, plumbing, plastering, room partitions, hallway details, bathroom renovations, kitchen remodeling, storage additions, air conditioning installation, and custom furniture are all higher. The budget is approximately $500,000-$750,000. The total price can increase further if high-end materials are used and specialized processes (such as smart home and eco-friendly materials) are outsourced. The standard construction period is approximately three months, but can easily extend to 100 working days. Be aware of the housing estate's requirements for scaffolding and special engineering arrangements.
1000 square feet unit full house decoration:
1,000 square feet is considered a luxury/large unit, with a living room, master bedroom, guest bedroom, study, two bathrooms, and an open kitchen being the most common design features.

Summary of the whole house decoration process and key points:
- The general process is: design consultation → demolition of old decoration → water and electricity/mud and water renovation → custom carpentry → painting and beautification → equipment installation → final construction acceptance → move-in/maintenance follow-up.
- Budget preparation should be based on one's own needs and financial budget arrangements, and more than 10% of flexible budget should be reserved in advance to prevent sudden price increases.
- It is recommended to choose a one-stop design and decoration team to clearly define the management and responsibility of the entire process. The quotation and contract content must list the details to avoid disputes and protracted construction.
- Try to communicate the desired effect in advance through drawings/3D designs. For custom materials, allow for production and delivery time (usually 2-6 weeks).
- When choosing a quotation, you should pay attention to whether it contains hidden charges, customer protection clauses, etc.
