We meet you, visit your site and discuss your brief whilst familiarising ourselves with the way you live to inform the desired outcomes for your project. Other considerations such as budgets and timeframes are also discussed, as well as forecasting the need for wider consultants and strategies for appointing the right contractor.

This initial meeting is followed by a Feasibility Study where we prepare multiple design options that are informed by detailed site analysis, planning constraints and sustainability opportunities. We meet again to review these options, running through which elements work for you and are to be explored further.

Stage 1

Following our review of the Feasibility Study, we use survey information to develop your favoured feasibility option / ideas from each option and transfer these in to scaled drawings. For us, this is the most important stage of the project where we explore the design in greater detail and establish the grounding concepts such as materiality and glazing strategies.

We frequently advocate engaging the local planning authority at an early stage and this is an ideal point to submit a pre-application if deemed necessary. This collaborative approach allows us to collate the planner’s feedback in to the scheme’s further development.

Having agreed the concept design, we use this stage to assemble the required planning documents and add the required details to our drawings to support a planning application. This is the point where plan arrangements and materiality are finalised alongside input from any consultants to ensure local policies are taken in to account.

Given our experience working with many different building types, we proactively monitor the planning / listed building consent applications to maintain a constant dialogue with the local planning authority.

The planning drawings are used as a base for adding further detailing to our layouts, elevations and sections to ensure the ideas discussed at our initial meeting are incorporated in to the design. This is a collaborative process where we explore the final quality of finishes and bespoke solutions for sustainable technologies and structural solutions to be integrated within the scheme.

We prepare a building regulations package, collaborate with consultants and prepare a set of tender information to be priced by carefully selected contractors.

This is the exciting point in the project where ideas on paper begin to take shape in reality. A Contract Administrator will administer the building contract to certify sums paid to the contractor and milestones in the build process. We can carry out this role or it can be outsourced whilst we maintain a focus on the quality of workmanship and realisation of the scheme’s initial concepts.

We always seek to be involved in site works so we can work with the wider project team to answer any questions and chair regular progress meetings on site. This allows us to keep updated and monitor any adjustments that may effect the project’s value or timescale.

Stage 5

Your keys are handed over and you have the freedom to enjoy your new project first hand. We remain in touch for a pre-agreed period to assist yourselves and the contractor with resolving any defects that come to light.

Once all defects are resolved we issue a final certificate to conclude the building contract. It is always nice to hear how clients are enjoying their home so we can take this feedback forward in to our future projects.
