Mono X team designed my first home and it was my best decision ever to have worked with them. It’s been 1.5 years since I moved in, and I am still enjoying every bit of the house.

F.A.Q.

What is the average HDB/Condo renovation cost in Singapore (2026) ?

The overall home renovation cost in Singapore varies based on whether it is a resale or BTO unit type, structural condition, and customized scopes (carpentry, plumbing and electrical etc.).

Below is a ranged reference of an average budget for the various property types:

Property Type	Budget Range
Condo / Landed Property	$ 30,000 - $ 120,000 +
5 Room Resale HDB	$ 80,000 - $ 95,000 +
4 Room Resale HDB	$ 70,000 - $ 85,000 +
3 Room Resale HDB	$ 50,000 - $ 65,000 +
5 Room BTO HDB	$ 60,000 - $ 70,000 +
4 Room BTO HDB	$ 50,000 - $ 60,000 +
3 Room BTO HDB	$ 40,000 - $ 50,000 +

Cost variations may incur due to some of the following reasons:

Evolving Material Selections

Eg. Upgrading tiles. Laminate specs, or countertop materials during the detailed design phases.

Scope Revisions

Eg Adjusting cabinetry lengths or adding custom features

Site Discrepancies

Eg. Actual on site measurements differing from architectural floor plans once keys are released

Hardware Upgrades

E.g. Transitioning to high-load architectural fixtures (Blum / Hafele systems)

While minor site adjustments are natural - especially in resale HDB and condo units - we recommend maintaining a 10% to 15% budget contingency. Mono X prevents predatory hidden variation orders by providing transparent, fully itemized line-item pricing before construction begins.
Ideally, you should engage an interior designer in Singapore 3 to 6 months prior to your estimated key collection date (or immediately upon purchasing a resale property).

Starting space planning early allows you to align your lifestyle requirements with an accurate renovation budget before committing to construction. It also streamlines the timeline for material selection, technical drawings, and HDB permit submissions, preventing costly project delays.
The interior design market in Singapore has a low barrier to entry, leaving homeowners vulnerable to inexperienced firms or unaccredited sub-contractors. Infrastructural works involving ACMV ( air-conditioning ), electrical wiring, plumbing, and structural masonry require strict technical oversight to comply with safety codes and building regulations.

Mono X is a HDB registered renovation contractor ( Directory of Renovation Contractors Registration No. HB-07-6560F). Our team is also architecturally trained with decades of combined experience, ensuring structural integrity, safety compliance, and legal peace of mind throughout your project.
On average, physical construction timelines in Singapore follow these standard windows:
Property Type
Typical Construction Timeline
Condo
6 - 16 Weeks +
HDB Resale Flat
8 - 16 Weeks
New HDB BTO Flat
6 - 12 Weeks
Note: These figures reflect physical site works. You should allocate an additional 4 to 6 weeks prior to construction for spatial conceptualization, 3D detailing, material sourcing, and obtaining official HDB/MCST renovation permits.
Whether you are seeking Japandi interior designer, warm minimalism, or modern luxury, Mono X executes a wide range of aesthetics across HDB, condo and landed properties.

However, we treat style as a natural byproduct of architectural functionality - not just surface decoration. Behind every aesthetic choice, we engineer custom carpentry, spatial proportions, and ergonomic layouts designed to serve your daily convenience while maintaining a timeless visual appeal.
Basic interior styling focuses primarily on surface aesthetics - such as paint colours, loose furniture selection, and decoration finishes. Architectural space planning, by contrast, addresses the core structural volume of your home. At Mono X, our design process is grounded in architectural principles: optimizing circulatory flow, balancing spatial proportions, refining lighting temperature, and applying chromatic psychology. This ensures your home isn't just visually appealing, but structurally sound, highly functional, and adaptable to your future needs.
Yes, HDB requires an official renovation permit for any works that alter the flat's structural or utility infrastructure.

Some examples of works requiring an HDB permit:

Hacking non-structural internal walls, floor tile replacement/re-screeding, bathroom sanitary overhauls, utility relocation, and window/glazing replacements.

Some examples are works NOT requiring an HDB permit:

Painting, wallpaper application, vinyl/laminate overlays (over existing tile), installing loose furniture, or built-in carpentry that does not alter structural walls.

All permit applications must be submitted electronically by an HDB registered renovation contractor prior to starting works.
