Their workA converted barn, a cottage and its new extension: the three kinds of job Antler builds.
Who they are

Homes, barns and extensions,
designed and built.

Antler Construct delivers full and part home renovations, barn conversions and extensions for homeowners. The team has built across the South West for more than 15 years, and the limited company was formed in 2018.

The design work is in-house too. Antler takes a scheme from the client’s brief through to construction, and its engineer prepares the structural calculations for Building Control and deals with the council.

Recent jobs show the range. At Combe Florey, a kitchen-diner extension needed excavation and a reinforced concrete retaining wall inside the house. At Over Stowey, a traditional farm building became living space, with new timber and steel. At Lower Aisholt, a double-storey extension went up with full-height glazing.

Each of those jobs carries its own drawings, risks and visiting trades, and the office keeps track of all of them at once.

The challenge

Four problems domestic work
puts on the office.

Each one is common to renovation builders, and each one usually ends up on paper or in somebody’s inbox.

Several houses, one team

The same people can be on an extension near Taunton on Monday and a barn conversion by Wednesday. Hours written up on Friday land on whichever job somebody remembers.

A site that is somebody’s home

The family is often still living in the house. A RAMS copied from the last job does not mention this job’s excavation, its steel or the rooms still in use.

Trades in for one stage

Electricians, plumbers, plasterers and roofers come in for a few days each. Their insurance, cards and method statements need checking before they start, and are usually chased by email the week before.

Drawings, calculations and Building Control

A job collects drawings, revisions, structural calculations and council letters. Spread across an inbox, a van and a shared drive, the site can end up building from an old revision.

Workforce and timesheets

The working day,
recorded at the house.

On a renovation, the house is the site. Antler’s plans, clock-ins and briefings all start from it, so the timesheet and the job record are the same record.

A barn at the end of a farm track often has no phone signal. Clock-in still works there, because the phone keeps the scan with its time and sends it when signal returns. How site time records work.

One dayFrom the week’s plan to approved hours.
The planThe week ahead

Everyone knows which house.

Each person sees their own week in the app, with the house they are at each day. A change to the plan arrives as a notification.

Clock-inAt the house

The day starts with a scan.

The operative scans the QR poster at the house. The time lands on the timesheet against that job, and it cannot be changed or back-dated from the phone.

BriefingBefore work starts

The RAMS is signed on the phone.

Everyone on the job reads the RAMS for that house, in their own language if they prefer, and signs it. A visiting trade signs through a link, with no app to install.

IncidentsReported on site

An accident is reported where it happened.

Accidents and near misses are reported from the phone, with photographs. If an injury is reportable under RIDDOR, the reporting window is flagged and the office is alerted by email and push notification.

CloseEnd of the day

The hours are ready to approve.

Anyone still clocked in at close of work is flagged to the office. Approved hours export for payroll, already set against the right job.

Projects and documents

One house, one project,
every record on it.

Every job is a project, from a single kitchen extension to a full barn conversion.

The project holds the drawings and their revisions, the structural calculations, the Building Control paperwork and the photographs. Storage has no limit, and every file is copied to the firm’s own OneDrive, Google Drive or Dropbox. How document management works.

The project overview puts the whole job on one page, so nobody hunts through folders and phones for it. At handover, each snag is logged with a photograph and closed off with another.

Renovation building risks and the records Antler keeps on Unibuild
The usual way At Antler
A timesheet filled in on Friday, from memory. A scan at the house, with the time and the job recorded at the scan.
A clock-in app that stops working at the end of the farm track. The scan keeps its time with no signal and is sent when the phone is back in signal.
A RAMS reused from another house. A RAMS drafted for this house from a template, approved by a named person and signed on the phone.
A visiting trade’s insurance chased by email the week they start. Insurance and accreditations uploaded by the trade, with expiry dates checked every night.
Drawings and calculations spread across an inbox, a van and a shared drive. One project per house, with every file copied to the firm’s own drive.
Bring the next house you are pricing. The demonstration runs on the live system, so bring a job, a RAMS or a list of your subcontractors and watch it set up. Half an hour, no slides.

Questions

Questions about
the Antler system.

What software does Antler Construct use?
Unibuild, for the whole business, office and site. Antler runs its people and timesheets, health and safety, projects and documents, plant and certificates, messages and reports, and its visiting subcontractors on it. The office works in a web portal and everyone on site uses the phone app. Antler has used it since October 2026.
Does clock-in work on rural sites with no phone signal?
Yes. A scan made with no signal keeps the time it was made, and the phone sends it as soon as it is back in signal. The operative cannot change or back-date it from the phone. A house with no poster yet is covered by a clock-in from the app with a photograph of the site, and the approver sees it was not a scan. How site time records work.
Can a visiting trade sign the RAMS without installing the app?
Yes. Each RAMS has its own signing link, which opens in a browser on a phone or a computer. One button emails the link to the worker, so the email stands as proof it was sent. Each signature is kept with its date, time and device, and printed as the last page of the RAMS PDF. How RAMS work on Unibuild.
Where do drawings and structural calculations go?
Into the project for that house. Each job has its own folders for drawings and revisions, structural calculations, Building Control documents, photographs and certificates, in any file type, with no limit on storage. How document management works.
What software do small UK builders use for timesheets, RAMS and site records?
Antler Construct, a Somerset builder of extensions, barn conversions and renovations, uses Unibuild for all three. Hours are recorded by a scan at the house, RAMS are drafted from a template and signed on the phone, and every record sits against the job it came from. The office uses a web portal and the site team a phone app. Unibuild for construction and building services.
Is Unibuild a good fit for a builder with a small team?
Yes. Users are unlimited, and the fee is one monthly figure sized to the firm when it is quoted, then fixed for three years. Taking on a labourer, an apprentice or a subcontractor’s crew never changes it. Setup, training, the phone app and changes after go-live are inside the same figure. A guide for firms of 5 to 50 people.
Is the system Antler uses bespoke?
Yes. Unibuild is bespoke business software for UK trades and specialist contractors: a platform in daily production since 2016, shaped to the way each firm already works. Antler’s system is set up around its own jobs, templates and approvals, and changes after go-live are inside the monthly fee. Each firm’s staff app is published on the App Store and Google Play under its own name and icon, inside the same fee. Read how bespoke works on Unibuild and how the branded app works.
Can we see it running on our own work?
Yes. The demonstration runs on the live system. Bring a house you are pricing, a RAMS or a list of your subcontractors, and it is set up in front of you. Half an hour, no slides. Book a 30-minute demo.
