For context, the average cost of a 4-room BTO renovation in 2025 is projected to fall between $51,000 and $61,800 — though the final figure ultimately hinges on how extensive your works are.

At first glance, you’d hardly guess that this renovation came in at under $30K. And isn’t that the dream? A home that looks effortlessly refined — without the hefty price tag.
This 4-room BTO in Yishun embraces soft curves and warm tones to create a calm, cosy atmosphere. Throughout the home, cost-effective materials like laminates were used to mimic the look of pricier finishes — a smart, budget-friendly approach that still achieves a polished, cohesive look.
A series of matching arches unify the living room and hallway, visually expanding the space without structural changes. Here, the designers went with straightforward carpentry and lighting details, such as cove lights and a simple false ceiling.
The galley kitchen keeps things functional and fuss-free, with warm wood tones and light cabinetry that brighten up the space. A clear glass partition neatly separates the service yard without blocking light, preserving the kitchen’s open feel.

This home in Tengah proves how thoughtful carpentry can completely transform a space. The kitchen and entryway are unified through uniform mint-green cabinetry that lends a soft, refreshing character to the interior.
A glossy green subway-tile backsplash adds texture and visual depth, balancing beautifully with the wood-toned upper cabinets and warm ambient lighting.
Custom-built for collectors, the full-length feature wall turns the dining area into a display-worthy centrepiece. Rows of backlit glass shelves showcase the homeowners’ figurine collection like a gallery, while alternating mint-green and white panels keep the look fresh and contemporary.
Beyond aesthetics, the feature wall also conceals the entrance to the corridor, streamlining the layout. Instead of a conventional sofa-and-TV setup, the homeowners opted for a simple dining arrangement and loose furnishings — a practical way to keep renovation costs in check without compromising style.

This sleek living-dining setup shows how simplicity and good lighting can make a compact layout feel elegant. Warm neutral tones, floor-to-ceiling curtains and a marble-effect dining tabletop give the space a refined, condo-like polish without major structural work.
A half-wall glass partition between the living room and study enhances openness, while a matching sliding glass door along the corridor keeps natural light streaming through.
A built-in banquette anchors the dining space, and a custom partition wall with cut-outs offers privacy while allowing for cross-wind ventilation through the home.
The wood-tone finishes, recessed shelving and geometric pendant lights subtly define the area while keeping the layout open and airy.
The galley kitchen pairs light-toned upper cabinets with dark woodgrain bases for contrast, finished with a clean glass backsplash and under-cabinet lighting. A curved countertop at the entry softens the edges of the space, creating a smoother transition between kitchen and living zones.

The TV feature wall pulls double duty here — providing privacy between zones while setting the tone for the home’s soft, sculptural aesthetic.
Thoughtfully designed cut-outs allow cross-wind ventilation to flow through the living area, while rounded corners, display niches and a built-in console keep the look seamless.
On the other side of the partition, a custom bench provides a practical spot for wearing and removing shoes. Matching display niches mirror those in the living area for design continuity, while a flushed door conceals the household shelter.
The open-concept kitchen is designed for effortless flow, with a dry kitchen flushed neatly along the wall and a dining table integrated with the kitchen island. A soft arch defines the transition into the service yard, tying the space together with a sense of visual rhythm.
Two rooms were combined to create a spacious master bedroom, with a gentle archway once again marking the transition between the sleeping area and the study.
Beside the bed, a built-in vanity with a full-height mirror adds both function and visual depth, complementing the home’s softly layered aesthetic.
On the opposite side, a rattan-inspired wardrobe with rounded edges brings texture and warmth into the space. A central display column showcases the homeowners’ PopMart figurine collection — a playful touch that personalises the serene, neutral palette.

A sleek teal-toned TV feature wall anchors the living space, while the glass partition behind it separates the adjoining study without breaking visual flow. Natural light filters through both areas, creating a bright, connected atmosphere.
The fully see-through glass partition defines the study and makes the whole communal space feel larger and more open. Teal-toned carpentry carries through the home, adding a touch of colour and cohesion to the neutral palette.
A world map feature wall brings a personal touch to the living area — with photos pinned beside each destination the homeowners have visited, it becomes a visual diary of their travels. Beside it, an arched niche showcases keepsakes collected from those journeys, while custom carpentry along the side conceals the household shelter and adds extra storage.
The dry kitchen sits neatly along the wall beside the dining area, its warm wood finishes balancing the cool teal tones. Beyond the streamlined cabinetry, this setup offers everyday convenience — perfect for grabbing a drink, brewing coffee, or putting together a quick snack without heading into the main kitchen.
In the main kitchen area, the teal cabinetry theme continues, paired with dark wood and marble-effect backsplash. Overhead cabinets and under-cabinet lighting enhance both storage and ambience.
The bedroom takes on a softer palette, with muted turquoise walls — and even the ceiling — painted in the same hue for a fully enveloping, restful feel.
Built-in wardrobes and a bedside niche keep essentials within reach while maintaining clean lines and a cohesive flow.

A mix of soft curves and clean lines gives this home a contemporary yet inviting feel. Warm wooden tones and tactile textures set the foundation, while pops of colour from the decorative pieces introduce an eclectic charm that enlivens the neutral palette.
In the bedroom, the vanity is seamlessly built into the wardrobe, keeping the layout compact and functional without sacrificing aesthetics. The clever integration of storage and built-ins contributes to the home’s sleek, tailored look.
Each bathroom in this home takes on a distinct theme — one bright and minimal, the other bold and expressive — showcasing how subtle shifts in tone and material can completely transform a space.
Though much of the home’s charm lies in its furnishings and decor, the higher renovation cost likely stems from the custom carpentry, spatial reconfiguration, and detailed finishings that bring everything together so precisely.

A soothing blend of Scandinavian and farmhouse influences gives this home its inviting, lived-in warmth. The consistent use of curves — seen in the ceiling, partition wall, and sofa — softens the look, while warm wood tones tie the open-plan layout together seamlessly.
A curved privacy partition with circular cut-outs allows light and cross-ventilation to flow through, creating a gentle sense of division between the entryway and living zones.
Here, built-in cabinetry with a bench makes wearing and removing shoes effortless, complemented by custom niches with under-cabinet lighting for displaying or airing them after use.
The homeowners also chose patterned floor tiles to subtly demarcate the transition from the entrance to the main living area.
The kitchen continues the theme of thoughtful detailing with patterned tiles that mark the boundary between wet and dry zones. A terracotta-toned kit kat backsplash adds warmth and visual texture, standing out beautifully against the otherwise neutral carpentry.
Instead of placing the sink within the master bathroom, it’s positioned just outside — freeing up interior space while maintaining a streamlined, practical flow. The consistent use of clean lines, wood accents, and a neutral palette keeps the look cohesive.
Green kit kat tiles set the tone for the master bathroom, lending a subtle touch of luxury to daily routines.
Across every corner of this home, it’s the intricate, well-considered details — from curved joinery to tailored storage and material transitions — that justify its $80,000 renovation cost.

Marble-look floor tiles and a matching TV feature wall create a sense of grandeur in this Tengah BTO, while warm LED strip lighting behind the display cabinet and open shelves enhances the overall luxe ambience.
The homeowner used a cohesive blue theme that extends from the foyer to the kitchen, tying the two zones together visually.
The kitchen and service yard have been seamlessly combined into a galley layout, with full-height blue cabinetry offering ample storage. The washer and dryer are concealed within the cabinetry for a cleaner, more integrated look.
A glass sliding door is tucked neatly into the cabinetry when not in use — a thoughtful detail that allows the kitchen to be enclosed during heavy cooking, yet remain open and spacious otherwise.
While the living and kitchen areas feature extensive built-ins and premium finishes, only the essential works were carried out in the bedrooms and bathrooms — allowing the renovation budget to focus on the home’s most visually striking zones.

This home is the first project on this list to cross the $100K mark — a budget typically more common among executive flats or older flats that require a full overhaul. For this BTO at Towner Road, however, the higher cost comes down to the extensive custom works and spatial reconfiguration.
Patterned tiles mark the transition from the entryway to the living area, setting a distinct visual boundary while adding character. A false ceiling with cove lighting subtly lowers the ceiling height at the entrance, creating the illusion of greater height throughout the rest of the home. Warm wooden tones complete the calm, cohesive palette.
The original living room was used as the dining area. A built-in banquette seat with storage underneath anchors the area and maximises space efficiency, complemented by a soft pendant light that centres the setting.

One of the common bedrooms was hacked down to be used as the living room. A structural wall that couldn’t be removed was cleverly integrated into the layout — a custom island counter now sits beside it, defining the zones without closing them off.
Custom bi-fold doors in matching wood tones add a seamless touch to the home’s overall aesthetic while keeping sightlines clean and unobstructed.

At $145,000, this renovation takes things up a notch — showcasing how a BTO can achieve the look and feel of a luxury apartment through cohesive lighting, textures, and meticulous detailing.
A rich palette of dark wood tones paired with warm ambient lighting creates a soft golden glow that extends throughout the home. The seamless carpentry and concealed storage maintain the sleek, uncluttered aesthetic.
The showstopper here is the indoor tree feature encased in glass — a statement piece that evokes the atmosphere of a high-end gallery or museum. Muted furniture tones, such as the grey sofa and dining chairs, lend a quiet, understated elegance to the open-plan space.
A clean, streamlined kitchen design with see-through upper cabinets showcases neatly arranged glassware — balancing functionality with display. The use of warm lighting here mirrors the overall mood of the home, tying each zone together visually.
In the master bedroom, open shelving doubles as both storage and display for the homeowner’s handbag collection, while also serving as a divider between the sleeping and dressing zones.
The sink and vanity was also shifted outside the master bathroom to enhance spatial flow and daily convenience.
By embracing shadow and contrast, this home achieves a timeless balance — moody yet calm, dramatic yet quietly luxurious in its restraint.
