DIY apartment interior design or a turnkey service?

Should you design your apartment interior yourself or hire a turnkey service? Short answer: DIY suits you if you have time, a clear taste and a simple apartment; turnkey suits you if you need optimised function, proper electrical and plumbing work and one accountable point of contact from drawing to handover. This article compares both options objectively so you can weigh them for your situation.

DIY interior design: control, but hidden risks

Advantages:

• Full control to your personal taste, independent of a design firm’s schedule.
• Saves the design fee if you can produce the layout yourself.
• The satisfaction of building your home with your own hands.

Common downsides:

• Easy to get function wrong: furniture placed against the circulation flow, too little storage, sizes that don’t fit the space.
• Electrical and plumbing are the hard, risky parts: badly placed wiring, sockets and water lines are expensive to fix later.
• Piecemeal buying tends to overspend and lacks consistency in style, colour and material.
• No one is accountable for the whole when something goes wrong.

Turnkey design service: thorough, but pick the right firm

Advantages:

• Professional team: trained architects offering several schemes through a proper interior design process to fit your taste and area.
• Deep material and function knowledge: advice on materials, care and budget-fit functional layout.
• Proper electrical and plumbing: wiring and water lines calculated to be safe and tidy.
• Overall consistency: living room, bedrooms and kitchen all coherent in style.

Points to note:

• There is a design fee.
• Some firms exploit an owner’s lack of knowledge to over-specify and inflate prices. Choose a reputable firm with a transparent estimate.

Advice for choosing well

If you go turnkey, study the firm’s track record, insist on a transparent line-by-line estimate and clarify the warranty policy before signing. A single-point design-build model brings design, production and construction under one accountable roof — reducing finger-pointing when the drawing and the site disagree.

AIC follows this model for its turnkey apartment interior service, with over 10 years in the trade (predecessor Nhan Viet from 2016, AIC founded in 2019), two in-house workshops (1,200 m² and 600 m²), and a BOQ estimate drafted in about 4 hours so you can size your budget before deciding. Every project is handed over with a warranty of up to 24 months and a scheduled maintenance plan. If you plan to do most of it yourself, the A-to-Z apartment fit-out guide will help you follow the standard sequence.

Frequently asked questions

Does DIY interior design really save money?

You save the design fee, but you risk extra costs fixing function, wiring, plumbing and inconsistent piecemeal purchases. For a complex apartment, the initial saving can be offset by later remediation.

How do I avoid a firm that over-specifies and inflates prices?

Demand a transparent line-by-line BOQ with clear quantities and unit prices, compare several firms, and review real projects they have delivered.

Does turnkey include construction?

With a design-build firm, turnkey includes both design and construction under one point of contact. Confirm the exact scope (design, build, loose furniture) in the contract.
