Who we work with

A wider team, on every project.

Nine disciplines, coordinated by us, appointed as your project needs them.

No residential project is delivered by architects alone. Every scheme needs engineers, surveyors and specialists at different moments, and getting the right one at the right time is most of what keeps a project moving.

We have worked with the same group of consultants for years. They are appointed as each project needs them and coordinated by us, so you get the expertise of a large practice without paying for its overhead, and one point of contact rather than nine. If you have your own consultants, builders or engineers, we're happy to work with them too.

01

Trusted builders

Builders we know and trust, invited to price your project at tender, all on the same drawings and specification.

02

Planning consultants

Over the years we've built up a network of trusted planning consultants who were planning officers at different councils. Their advice can give you a quick first read on a site, and when a formal pre-application with the council is the right next step, we can prepare and submit that too. Where a site has been refused before, they help us build a strong case before anyone redesigns blindly.

How we work

One practice, start to finish.

On site. The chartered architect who drew it is the one who inspects it, values the work and signs the certificates.

We work through the RIBA Plan of Work, and we charge by stage, so you commit one phase at a time rather than to the whole project on day one.

0–1

Appraisal & brief

The plotwise report by DZP, site appraisal, measured survey and the brief. Establishing what is possible and what it is worth before design begins.

2–3

Design & planning

Concept design and an early cost estimate from a quantity surveyor, then the planning application or lawful development certificate, and discharge of conditions once consent arrives.

4

Technical design & tender

Construction drawings and Building Regulations approval, the detailed specification, the tender and the building contract. Principal Designer duties under CDM 2015.

5–6

Construction & handover

Site oversight and contract administration, then the handover pack and the defects period.

7

Use

Once you've moved in, we're still here: help during the defects period, and after that by agreement.
