Most projects go wrong right at the start, when big decisions get made on guesswork. So we start with numbers. Using your plans or your plot, we produce a realistic cost benchmark drawn from real Mosaic projects, so you know whether your ambition and your budget match before committing to anything further. This stage protects you from moving forward on incorrect assumptions.
Our Process
One team takes your home from first idea to front door keys
Building a bespoke home usually means finding an architect, a planning consultant, a structural engineer, a builder and a dozen trades, then hoping they all talk to each other. With Mosaic, you make one appointment. We handle the design, the planning permission, the engineering, the people and the build.
- Planning permission handled
- Architects and engineers arranged
- Trades hired and managed for you
- One point of contact throughout
Everything, covered
What end to end actually means
You hire Mosaic. We bring everyone else.
Design
Concept to detailed drawings, led by our design team or working alongside an architect you already have.
Planning permission
We prepare, submit and manage your planning application with the council, and deal with any conditions.
Structural engineering
Calculations, building regulations and technical sign off, all arranged and coordinated for you.
The right people
Surveyors, consultants and specialist trades, sourced, hired and managed by us. You never have to recruit anyone.
The build
Our team constructs your home with live cost tracking, quality inspections and a clear programme.
Handover
Professional snagging, final checks and commissioning, then the keys go in your hand.
Already have an architect or drawings? That works too. We pick your project up from wherever you are, bring the same structured approach and manage everything from that point on.
The Mosaic Method
Four stages. One straight line.
Every Mosaic project moves through the same four stages. Each one answers a simple question before you commit to the next, so you always know where you stand, what it costs and what happens next.
01
DiscoverOpinion of Probable Cost
In plain English
We tell you what your home is realistically likely to cost, before you spend money on detailed design.
Typically 1 to 2 weeksYou get: a written cost benchmark and a clear next step
A benchmarked cost assessment
A realistic, experience based view of likely build costs, matched to your proposed design or site.
A high level programme
An outline of how long your project is likely to take, from start to finish.
A clear roadmap
A straightforward plan for the next phase, so you know exactly what happens next and why.
02
DefineFeasibility Study
In plain English
We check that your plot, the planners and your budget all agree, before you commit any further.
A good idea on paper still has to work in the real world. We look at what the council is likely to approve, what your site can physically support and whether the numbers still stack up against Stage 1. At the end you get a clear written recommendation: proceed, refine or rethink. No wasted months, no nasty surprises later.
Typically 4 to 6 weeksYou get: a written feasibility recommendation
Planning and policy review
How the council is likely to respond, with any sensitivities flagged early.
Site and technical assessment
Access, ground conditions, services and neighbouring constraints, all checked.
Budget alignment check
We test the emerging design and specification against your Stage 1 cost range.
Risk identification
Planning, structural or commercial risks flagged before they become expensive.
Programme validation
We confirm the timeline is realistic, not optimistic.
Your project platform, set up
One online home for every document, decision, cost and message, from day one.
A clear recommendation
Proceed as planned, refine the design or reposition the strategy. In writing.
03
PreparePre-Construction Agreement
In plain English
We line up every drawing, every price and every tradesperson before a spade touches the ground.
This is where most builds are won or lost. We finalise the design, complete the engineering, discharge planning conditions, lock in prices with trades and build a fully sequenced construction programme. By the end, your project is not just designed, it is genuinely ready. When we start on site, nothing is left to chance.
Typically 8 to 16 weeksYou get: a build ready project and a refined cost plan
Design coordination
We work with your or our architect and engineers to resolve details and make drawings build ready.
Engineering finalised
Structural, mechanical and electrical elements reviewed and aligned to your budget.
A refined cost plan
The feasibility numbers evolve into a detailed cost plan, increasing certainty before contract.
Trades engaged early
Key subcontractors and suppliers priced and booked, validating cost and availability.
A sequenced programme
A full construction programme with critical path activities and realistic milestones.
Risks reduced upfront
Cost, programme and coordination risks identified and dealt with before breaking ground.
Construction readiness review
The project is technically aligned, commercially validated and ready for a formal building contract.
04
DeliverConstruction and Delivery
In plain English
We build your home, manage every trade on site and hand you the keys.
One accountable team takes your home from groundworks to handover. Because every earlier stage was properly controlled, the build runs to a clear programme with live cost tracking, regular quality inspections and structured updates through your project platform. You always know what is happening, what it costs and what comes next.
Duration depends on your projectYou get: your finished home, professionally handed over
Dedicated project leadership
A single accountable team overseeing everything from groundworks to completion.
Structured programme management
The build follows the agreed programme, with sequencing and critical path control.
Cost control and transparency
Ongoing cost monitoring, variation management and clear financial reporting throughout.
Your project platform
Programme, costs, approvals, documents and messages, all in one place you can check any time.
Quality management
Regular site inspections, consultant coordination and strict adherence to specification.
Clear communication
Structured updates and milestone reporting, so you are never chasing for news.
Health, safety and compliance
Full compliance with current regulations and statutory requirements, managed by us.
Handover and completion
Structured snagging, commissioning and formal handover, finished properly and ready to occupy.
Timeframes
How long does it all take?
Every home and brief is different, but here is the typical shape of a Mosaic project.
01
Discover
Opinion of Probable Cost
1 to 2 weeksFinancial clarity before you commit to anything.
02
Define
Feasibility Study
4 to 6 weeksConfirm what can be built, and that site, planning and budget align.
03
Prepare
Pre-Construction
8 to 16 weeksDesign, engineering, costs and trades finalised before site start.
04
Deliver
Construction and Handover
Project dependentA structured build with live cost, programme and quality control.
Timings vary with project complexity, planning authority response times and the level of technical coordination required. The earlier the process begins, the stronger the outcome.
Cost clarity
No surprises on cost
A bespoke build should never come with hidden extras. So here is exactly what sits outside your build contract, agreed upfront and in writing.
VAT
New build construction is typically zero rated. Where a reclaim applies, we manage the process on your behalf.
Window dressings and blinds
Chosen and fitted after handover, usually as part of interior design.
Specialist bespoke joinery
One off furniture pieces and fitted joinery beyond the core specification.
Floor coverings and soft finishes
Carpets, rugs and similar soft furnishing items.
Loose furniture and furnishings
Sofas, beds, tables and everything you would take with you if you moved.
External works and landscaping
Gardens, driveways and boundary treatments, quoted separately if you want them.
Soft finishes, furnishings and specialist joinery usually form part of a dedicated interior design package, costed and managed separately. If you would like, we can coordinate all of it within your wider project so everything still runs through one team.
Not building from scratch?
Major Extensions and Renovations
Our primary focus is bespoke new homes, but we bring exactly the same four stage process to significant extensions and full renovations. Same clarity, same cost control, same single accountable team from the first conversation to the finished space.
Stage 1 starts with a chat
Start with a conversation, not a commitment
Tell us about your plot, your plans or just your idea. We will tell you honestly what it is likely to cost and what to do next.
It costs nothing to find out where you stand.
