Built into every project

An AI project manager that knows UK building — and your build

Five assistants embedded where you work: stage guidance on the project overview, budget sense-checks on the budget, programme drafting on the schedule, planning triage before you commit, and healthy-home advice room by room.

The Problem

Why Home Projects Need More Than a Tracker

Tracking tells you where you are. It doesn't tell you what good looks like at each stage — or what's about to go wrong.

Every Stage Is Your First Time

A builder has poured a hundred foundations; you're pouring your first. What inspections need booking? What should be on site before the groundworkers arrive? Which questions expose a corner about to be cut? Generic articles don't know your project — so you learn by expensive mistake.

Budgets Fail on the Lines That Aren't There

Most budget blowouts aren't overspending on lines you planned — they're the lines you never wrote: building control fees, scaffolding overruns, skips, temporary services, making-good the landscaping. By the time they surface, contingency is gone.

Planning Rules Read Like a Legal Exam

Permitted development limits, prior approval schemes, conservation-area carve-outs, Article 4 directions — getting it wrong risks enforcement against a finished extension. Getting a definitive answer usually means fees and weeks of waiting before you even know which route you're on.

The Solution

Five Assistants, One Build Companion

Each assistant lives on the tab where its job happens, and answers from your real project data — not from a blank chat box.

Project Assistant

Pick your current stage — say, foundations — and get an ordered checklist, the materials to have ready, Building Regulations points with Approved Document references, the building-control inspections to book, sharp questions for your builder, and the mistakes homeowners make at exactly this point. One click turns the checklist into real tasks in your programme.

Budget Review

Reads your actual budget lines and flags what looks under- or over-provisioned against typical UK cost expectations, lists the commonly forgotten items missing from your budget, checks VAT treatment against your project type, and recommends a contingency level — every figure framed as a sense-check to validate, never a quote.

Programme Builder & Review

No schedule yet? Describe the build and get a complete UK-sequenced draft programme — phases, tasks, durations, dependencies — applied straight onto your Gantt in one click. Already have one? Get a health check: missing stages, sequencing risks, and durations that look optimistic.

Planning Check

Describe the proposed work, tick the constraints that apply, and get a first-pass triage: likely permitted development or likely needs permission, the factors driving the answer, what to submit, and typical timelines — always routed to a Lawful Development Certificate or pre-application advice for written certainty.

Healthy Home

Ventilation, damp and mould, overheating, air quality and VOCs, light and noise — room-aware recommendations with the Approved Documents that apply, what to look for in products, red flags to act on, and when to bring in a professional.

From Answer to Action

Assistant output doesn't sit in a chat window. Checklists become tasks in your phases. Draft programmes become your actual Gantt. Guidance lands in the tool you manage the build with — where it changes what happens on site.

Why It's Different

Context, Curation, and Guardrails

The three things a generic chatbot can't give you.

Grounded in Your Project, Not Generic Advice

The assistants read your real phases, tasks, budget position, rooms, and milestones before answering. Guidance about 'your foundations' means the foundations in your programme, at your stage, with your numbers.

A Curated UK Knowledge Base, Dated and Sourced

Answers draw on a maintained corpus of UK reference entries — Approved Documents, permitted-development limits, building-control processes, grant schemes like the £7,500 Boiler Upgrade Scheme, and VAT reliefs — each verified on a stated date, so time-sensitive figures come with their 'as of' date instead of stale confidence.

Guidance With Guardrails

The assistants never produce structural calculations or planning determinations. They tell you when a structural engineer, architect, Part P electrician, Gas Safe engineer, or building control must be involved — because knowing when to call the professional is part of good guidance.
