What we solve

Your project is in safe hands throughout the entirety of the project lifespan.

Enquiries arrive as a problem rather than a building: a refusal to overturn, a listing to work with, a green belt site with a value case. Open any service to see what it involves.

Technical design
Building regs and construction packages
+
Project image

We help to execute both straight forward and complex technical drawing and Building Regulations packages and do not shy away from construction detailing which can be effectively priced by a QS and delivered by a contractor. In some instances our technical drawing suites for complex sites can amount to many hundreds of annotated and buildable construction drawings which are NBS compliance and operate within shared BIM environments.

Coordination between disciplines including structural, services, fire engineering teams, security, specialist consultants, surveying teams

Concept design
Options appraisal, massing studies, precedent
+
Project image

Early-stage options tested against the defined brief, the site and the planning position, so the direction is chosen by the team with as much information supporting it as possible. We are able to integrate deep rooted development knowledge to ensure the scheme is deliverable and explores various use cases to achieve attractive GDV and outcomes.

Options appraisal testing use-cases
Precedent and policy review at a local and national level (LP, SPD, NPPF etc.)
Establish stakeholder relationships

Feasibility studies
Pre-purchase and land acquisition advice
+
Project image

We have a track record of testing both feasibility work architecturally, but also through the lens of other disciplines to ensure planning sensitivies and opportunities are analysed

Pre-purchase and land acquisition advice
Capacity and constraints testing
Viability and feasibility testing to present a suite of options to the client or developer
Local and national constraints including AONB, Green Belt, Conservation Area, Article 4, SPD, Housing Supply and Case Law

Masterplanning
Site-wide plans and multi-unit development
+
Project image

In conjunction with viability assessment and feasibility work, as part of a wider conceptual brief, we have a track record in adding value to masterplans through intelligent planning strategy, architectural design and viability testing.

Acting as contract administrator through construction - valuations, instructions and inspections - so the built result matches what was consented.

Multidisciplinary work
Leading consultant teams across practices
+
Project image

Complex sites rarely call for one discipline. We have extensive experience acting for consortiums, leading teams of 30+ professionals across more than five disciplines - structural and M&E engineers, planning specialists, heritage advisors, quantity surveyors, scientific analysts, party wall surveyors and more - with our practice as the single point of contact throughout. On our largest diplomatic commissions, teams of over thirty consultants working across multiple languages are commonplace, producing bilingual reporting that can run to 3,000 pages at each RIBA stage. Clients get complete accountability for it: the whole consortium remains security-vetted, and background checks, action logs and structured reporting mean the hierarchy can be traced at every stage.

Security clearance
Vetted delivery for embassy and diplomatic sites
+
Project image

Diplomatic and government commissions carry requirements that sit outside ordinary planning and design work - vetted personnel, controlled handling of sensitive drawings and information, and the ability to work within secure, often still-occupied embassy buildings. Our core team holds the security clearances this work demands, and we extend vetting to the wider consultant team as each project requires, so a mission or government client can appoint one practice for both the building and its security obligations. Every individual working on a cleared project is background-checked and logged before they set foot on site, with that record maintained for the life of the commission. Moreover, we ensure from the top down that values are aligned and that the long-term relationships these projects demand are maintained.

11
Planning strategy & evidence
Pre-application strategy for contentious sites
+
Project image

Difficult sites can be won or lost before an application is ever submitted. We build the planning strategy alongside the design - financial modelling and viability assessments, market demand assessments, pre-application engagement, committee-facing evidence, and the specialist reports that give a contentious scheme its footing, from heritage statements to technical evidence prepared for sites others have already been refused on. Where a scheme is likely to be tested, we prepare the evidence base to withstand that scrutiny from the outset, rather than assembling it in response to an objection. Not only do we succeed where others fail, we add value to your site. An exceptional case in point is an increase in site GDV from around £500,000 to a market disposal value north of £20,000,000 post build-cost.

12
International & cross-border projects
Design and delivery beyond the UK
+
Project image

Not every client or every site of ours sits inside the UK. We deliver projects for overseas clients and on international sites, coordinating design and construction information across jurisdictions, time zones and, where required, languages - currently including live work in Jeddah alongside our London and Home Counties commissions. We also work with international clients, including governments, on projects in London. The same RIBA 0–7 lead-consultant model applies wherever the site is, adapted to the local planning and regulatory framework rather than exported wholesale, and in some instances worked in tandem with international models.

13
BIM services
In-house modelling to ISO 19650 standard
+
Project image

We deliver in Revit and the wider Autodesk suite, maintaining our own in-house BIM-trained personnel rather than outsourcing the model. Working in a shared federated model to BS EN ISO 19650 allows every discipline - architectural, structural, M&E - to design against the same live information, with clash detection catching conflicts on screen rather than on site. Combined with survey data and the wider software toolset, it means design, coordination and construction information stay accurate and current across every RIBA stage, for one consultant team or thirty.
