Main contractor for architect-designed projects in Hertfordshire

If you already have an architect and a developed design, JBP can build it. We manage the site, trades, programme and handover across Hertfordshire, Bedfordshire and North London.

Who it’s for

A construction partner for your architect-led project

You have an architect and a design you’re happy with. Now you need a builder who will follow it, ask the right questions early and run a well-organised site.

Your architect stays in charge of the design and we build to their drawings and specification. Before we start, we agree in writing what is and isn’t included, so there are no surprises later.

01

Pre-construction review

We go through the drawings, specification and site before pricing, and flag anything missing or unclear before it holds up ordering or work on site.

02

Running the site

We plan the order of work, manage the trades and make sure the structure, services and finishes fit together.

03

Programme and progress

You and your architect get regular updates on progress, what’s coming up and any decisions we need from you.

04

Quality and completion

We arrange inspections, finish any outstanding work and hand over the documents you need. Any defects are logged and put right.

What we do on your project is set out in the building contract. To start, send us the drawings, the specification and your target start date.

Our process

How traditional construction works

It starts with your architect’s drawings.

Share the design

Send the drawings, specification, location and intended programme.

Review the information

We check for missing details, access issues and anything unclear in the scope.

Agree the appointment

We agree the price, the programme and who is responsible for what.

Deliver and hand over

We build it, keep you updated and finish every item on the list.

Beaumont Mews

At Beaumont Mews, retained historic fabric, structural repairs and difficult ground conditions meant the construction work had to be carefully coordinated. The case study shows the kind of detail that needs attention before and during a complex build.

Before you start

Traditional construction FAQs

Need advice on your specific project? Talk to the JBP team.

Do I need complete drawings before contacting JBP?

No. We can help work out what’s missing. To give you a firm price, though, we’ll need a clear scope and specification.

Can you work with our existing architect?

Yes, that’s how this route works. We agree with your architect how instructions, queries and design changes will be handled.

How is this different from design and build?

With traditional construction you appoint the architect and the builder separately. With design and build, one company is responsible for both the design and the build. Your contract sets out exactly who does what.
