Assembly Interiors
Courtney's design specs are credited by multiple builders as the reason their projects ran ahead of schedule.
The standout pattern from 24 reviews is that clients describe her as cost-neutral or cost-positive: multiple customers specifically mention that avoiding unnecessary builder upgrades or having tightly-scoped specs covered the design fee and then some, which is a more concrete value claim than most design consultancies can point to. She works across residential renovations, new home builds with volume builders, commercial fitouts, and has delivered remote online design consultations internationally — so if your job sits outside a straight renovation brief, it's worth contacting her directly to confirm scope before assuming she won't take it on.

About Assembly Interiors
Courtney is the sole designer and principal behind Assembly Interiors, and her name appears across virtually every review — she's the person you'll work with from first brief to final presentation. Her core work is residential interior design: kitchen, bathroom, laundry, and living space renovations where she produces detailed design specifications, realistic colour renders, and full material and finishes schedules. Builders and tradespeople mention specifically that her documentation makes quoting and trade coordination easier, with one builder noting it helped a project finish ahead of schedule — an unusual credential for a designer to carry. Reviews suggest she's particularly well-suited to homeowners building with volume builders (she's been cited by name in Boutique Homes selections appointments), undertaking multi-room renovations, or simply trying to avoid the decision fatigue that comes with choosing tiles, flooring, and fittings simultaneously. She's also taken on commercial fitouts — a restaurant and bar popup, and an office redesign for Keypath Education — and has worked remotely with an overseas client in the UAE, sourcing products locally to that market. For renovation clients, customers most often mention that her practical guidance helped them avoid unnecessary builder upgrades, meaning her fee can offset itself financially before a tile is laid.
Best for: homeowners renovating kitchens, bathrooms, or multiple rooms who want a detailed design specification ready for builders; people building with a volume builder who need guidance through a selections day; and clients who want ongoing designer support throughout the construction process rather than a one-off consultation.

Who will I actually work with at Assembly Interiors?+
Every one of the 24 Google reviews names Courtney personally as the designer on the project — this is a sole-practitioner studio, so you'll work directly with her from the initial discovery meeting through to final design presentation. There's no junior designer or account manager in between. Clients describe her as accessible for ongoing questions even after the design is delivered, which is worth confirming when you discuss scope.
What does the design process typically look like?+
Based on what customers describe across multiple reviews, Courtney typically starts with a discovery conversation to understand your brief, style preferences, and budget. She then prepares a design concept including realistic colour renders and a detailed specifications document covering materials, finishes, tiles, flooring, and fittings. Clients building with volume builders mention she also attends or supports selections appointments. The final package is designed to be handed directly to builders or tradespeople, which multiple reviewers say reduced confusion and helped projects run more efficiently.
Can Assembly Interiors help if I'm building with a volume builder like Boutique Homes?+
Yes — at least one review specifically names Boutique Homes as the builder Courtney worked alongside, and the customer describes her role as guiding them through a full selections day covering colours, tiles, flooring, fittings, and finishes in a single session. Reviews suggest this is a genuine niche for her, with clients noting she helped them avoid costly upgrades they didn't need and made selections decisions feel manageable rather than overwhelming. If you're heading into a selections appointment with a volume builder, this is one of the clearer use cases in her review history.
Does Assembly Interiors only work locally on the Mornington Peninsula?+
The studio is based in Frankston and multiple reviews reference Peninsula and Bayside projects specifically. However, reviews also show she has worked with clients remotely — one customer based in the UAE describes receiving a full room redesign online, including sourcing products from UAE-based stores. Commercial projects in Melbourne are also mentioned. If you're outside the immediate area, it's worth asking about her remote service offering directly.
Is hiring an interior designer likely to pay for itself on a renovation?+
Several customers — including two in separate reviews — specifically mention that Courtney's guidance helped them avoid unnecessary builder upgrades, and that this saving offset or exceeded her design fee. One client also notes that her detailed specifications allowed a carpenter to complete works ahead of schedule, which can reduce trade costs. These are customer accounts rather than guaranteed outcomes, but the pattern appears in enough reviews to be worth discussing when you enquire — ask her how she approaches budget conversations during the brief.
