Bloooom, by Zaltt. A private visual workspace for architects
Stop drafting options just to see if they work.
The early design phase is a mess of fluid ideas, tight deadlines, and grey boxes. Bloooom lets you test materials, light, and form directly over your sketches and massing, before your team spends billable hours drawing them. Your lines stay locked. Your style stays yours. Your work stays in your building.
Built for the Sunday-night pre-app dread, and the quiet worry about where client sketches end up.
- Your lines stay locked
- Learns your studio's hand (Enterprise)
- Private, down to the plug (Enterprise)
From instinct to decision
Type what you want to see. Watch it appear.
Ask for a concept the way you would brief a colleague, in plain words, and watch it rendered in front of you. The film shows the whole journey in 48 seconds: from a written idea to a finished study, without leaving the browser.
The friction we pretend doesn't exist
Every option you test today costs billable hours. Most of them get thrown out.
The over-modelling trap
Your team spends billable hours modelling detail for a client option that might get thrown out the minute they see it. You are burning project fee to test an aesthetic hunch.
The grey-box blindspot
It is hard to judge a concept staring at raw massing and wireframes. You want to feel how a timber-clad first floor sits on a heavy masonry base, but your tools make you wait until the drawing stage to see it.
The quiet NDA panic
Somewhere in your office, someone is uploading a confidential client sketch to a public AI site just to see it rendered. Every upload is a leak, and a liability, waiting to happen.
The concept loop
From grey block to decision, in one sitting.
Concept iteration for architects, rebuilt as a habit loop: four short steps you run dozens of times a day, without leaving the browser. Start from a written brief or from your own sketch.
Start where you are
- A pre-app deadline looms and the north elevation is still a grey box
- Open Bloooom in any browser on your office network
- No render engine to boot, no visualisation specialist to brief
Drop in a sketch
- Drag in a hand sketch, a SketchUp block-out, or a clay view
- Your wall lines and volumes lock in place
- Say it the way you would to a colleague: "handmade red brick, soft winter light"
Watch the options roll
- Concept studies come back in moments, in your studio's style
- Same proportions every time; only the materials and light change
- Test dozens of brick bonds and cladding finishes in one afternoon
It learns your hand
- Every study you keep teaches Bloooom your studio's taste
- Each loop through brings it closer to your signature
- Your youngest assistant tests options that carry the partners' eye
Your drawing stays yours
Drop in a sketch. See the material, not the grey box.
Start from your own hand sketch instead of a blank prompt, and Bloooom wraps your exact lines in real materials and light. Drag the handle: the sketch, and the study you get back.
Same lines, locked
One drawing, four material passes. The geometry never moves; only the study changes.
"handmade red brick, winter light"
Your practice's moat
Anyone can buy software. Nobody else has your archive.
Every sketch, detail, and finished render your studio has produced is design equity. Bloooom learns from it, privately, so the studies it returns look like your work, not the internet's average. Your style model belongs to your practice and never trains anyone else's.
The Enterprise station at a glance. Cloud tiers run in Zaltt's cloud; the tier matrix below shows exactly where each tier lives.
Where your work lives
Three tiers. No fine print about where your work goes.
We don't hide where your unbuilt ideas go. "Never leaves your building" is a strong claim, so we scope it precisely: it applies to the Enterprise on-premise station only, never to a cloud deployment.
Unplugged. The cloud tools go dark. Bloooom keeps rendering.

In plain terms
What is Bloooom?
Bloooom is a private visual workspace for architecture studios. It sits upstream of your CAD and BIM tools: you drop in a sketch or massing view, describe the materials and light you want to try, and get back concept studies in your studio's own style, with your lines locked. On the Enterprise tier, it runs entirely on a box inside your office.
Bloooom is built by Zaltt, a creative studio working where the physical and the digital meet. The studio renders by hand, and builds tools. Bloooom is the first of them.
| Bloooom | Public AI tools | Traditional rendering | |
|---|---|---|---|
| Early concept speed | Real-time options | Fast, but the lines go wrong | Slow: model everything first |
| Your lines | Locked to your sketch | Warped and redrawn | Exact, but hours of setup |
| Your style | Learned from your archive | The internet's average | Built by hand, every time |
| Your confidential work | Enterprise: never leaves your building | Uploaded to public servers | Stays local |
| Getting started | One box, whole studio | Per-seat subscriptions | Licenses and specialists |
The architect behind it
Built by an architect, for architects.
Unmesh Lele
Founder, Zaltt
An architect at heart, an HCI specialist, and a designer fueled by fresh espresso and raw paper. Spatial design is where my passion sits, especially when it comes to giving great ideas the visual presence they need to succeed. That desire to elevate every concept led me to found Zaltt. Blending paper sketches, 3D software, advanced rendering, and physical maquette work, I craft every visual published here to elevate spatial thinking and bring compelling concepts to life.
Questions architects ask
Frequently asked questions
What is Bloooom?
Bloooom is a private visual workspace for architecture studios. You drop in a sketch or massing view, describe the materials and light you want to try, and it returns concept studies in your studio's own style, with your lines locked. Its Enterprise tier runs entirely on a box inside your office.
Does it replace our CAD and BIM tools?
No. Bloooom sits upstream of them. It is designed to help you test ideas, material pairings, and volumes quickly, before you invest time and fee in coordinated technical drawings. You keep modelling exactly as you do today.
Will it redraw or distort our design?
No. Unlike public AI tools that rewrite your image, Bloooom keeps your lines locked. Your floor plates, wall lines, and volumes stay exactly where you drew them. Think of it as an interactive cladding and lighting study laid directly over your sketch.
How is Bloooom different from Midjourney or other AI image tools?
Three ways. It learns your studio's style from your own archive rather than scraped web images, so studies come back looking like your work. It locks your lines instead of hallucinating a new building. And on the Enterprise tier, your work never leaves your office, while public tools require uploading to someone else's servers.
Is our confidential work secure?
On the Enterprise tier, yes, physically so: the software runs on a box inside your building, connected only to your internal network, and nothing is sent to the internet. You can pull the network cable out of the wall and it keeps working. Cloud tiers are private but run in Zaltt's cloud, and we say so plainly.
Does Bloooom train on my firm's data?
Your images train only your own firm's private style model. They are never used to train shared models or any other studio's model, on any tier. On the Enterprise tier, training runs on your own hardware and the trained model belongs to your firm.
Do we need rendering specialists to use it?
No. If you can describe a material palette to a colleague, you can drive Bloooom. You write what you want to test in plain language, like "handmade local red brick, Flemish bond, dark bronze window trim, soft winter daylight," and drop in a hand sketch, a SketchUp block-out, or a clay view.
How much does Bloooom cost?
Enterprise stations are quoted per practice, based on the number of trained styles and hardware. Secure a station and we will walk you through it. Pricing for the cloud tiers will be published when they launch.
We are installing studio stations with a first cohort of UK practices this quarter.
We handle the installation, plug the station into your network, and set it up on your built portfolio, so your team can start testing ideas in your signature style from day one.
