CONCEPT AND SKETCH DESIGN
This is the most creative work stage and can be extremely exciting for you and for us as Architects. The concept is normally developed following an extensive site analysis and ensuring we have a clear understanding of your brief. For inspiration have a look at some of our favourite projects here.

The concept and design stage is a very important stage; the best buildings focus on the concept throughout the following work stages. We normally develop 2D plans based on the concept and work closely with you to ensure you understand the concept and embrace the plans. We then develop a 3D model which enables you to see the building for the first time. These models are also used in Virtual Reality (VR) to test the design. We can then invite you to our office to experience the full VR and better understand the design:
This design phase will normally take place over a number of weeks with several design meetings until we are all content. Understanding you and your requirements and getting these into this stage is normally undertaken as a percentage of the anticipated construction cost.
We are able to produce physical models at an additional cost, which can help you to better understand the design or provide a visual aid during presentations to members of the public and Parish Councils.

PRE-PLANNING APPLICATIONS
We like to work as closely as possible with the Planning Department and recommend the pre-application process. This gives us a way of testing the water with our concept and design and the opportunity to meet the planning officer.
This stage is not necessary, but we find that it can be very informative and help to steer the design proposals towards a successful outcome. Generally, the more design information that can be submitted, the more informative the feedback.
The aim is to receive a positive response from the planning officer to give you the confidence to develop the proposals into a Planning Application. Typically we will provide A Location Plan, Block Plan, Site Plan, 2D Plans, 3D images, A3 booklet.
This pre-application is normally undertaken as part of the Concept and Sketch Design stage.

PLANNING APPLICATIONS
Once the Concept and Sketch Design process are complete and the pre-application response is received, we begin developing the proposals for a Planning Application.
This may include making some design amendments to satisfy the planning officer’s feedback.
At this stage, we will provide, A Location Plan, Block Plan, Site Plan, 1:100 Scale 2D Plans, 1:100 2D Elevations, 3D images, A3 Planning Booklet incorporating the Design and Access Statement.
The majority of projects we design are in sensitive locations such as coastal or rural areas and require Visual Impact Assessments to demonstrate that the impact of the design has been considered within the immediate environment and wider context.
Photomontages of the proposal help to portray how the building will appear from the main public vantage points. We have close relationships with all the consultants you are likely to need throughout your project, such as Planning Consultants, Landscape Architects, Ecologists, Arboriculturalists, and Land Contamination Specialists.

This enables us to organise and manage your consultants, freeing you to enjoy the process. This work stage is normally undertaken as a percentage of the anticipated construction cost.
PARISH COUNCIL PRESENTATIONS
Where a project is controversial or on a sensitive site, we often present proposals to the Parish Council prior to a planning application being submitted. A 10-minute presentation followed by questions enables the Councillors to better understand the proposal and provide us with valuable feedback.
This is the first time that your project is presented in front of the public. We can also attend the Parish Council meeting when the planning application is considered to answer any questions that may arise.
This process can be useful to appease a planning officer’s concerns about a project and can also help to reinforce their support. If required, this stage is normally undertaken on an hourly rate basis.
NEGOTIATING APPROVALS
ARCO₂ stays in contact with the planning officer throughout the determination period. Occasionally, planning applications become drawn out due to unexpected comments from statutory consultees such as Highways Officers, Tree Officers, Conservation Officers, the Environment Agency, or the Parish Council.
We may need to undertake additional work to satisfy these consultees, which will be undertaken on an hourly rate basis.
BUILDING REGULATIONS
After celebrating your planning approval, you are still some way off starting your exciting construction project. The Building Regulations require us to demonstrate to Building Control how the Approved Documents have been met. This entails A detailed 2D Site Plan, 1:50 Scale 2D Plans, 1:20 2D Sections, 1:50 2D Elevations, and a Written Specification.
We also need to produce U-Value Calculations and liaise with a SAP Assessor to provide a design stage SAP Calculation and an EPC. We work with a Structural Engineer who will provide calculations and drawings.
The amount of work that we produce for this stage is comparable to that of the Concept and Sketch Design and Planning Application stages combined. This work stage is normally undertaken as a percentage of the anticipated construction cost.
CONSTRUCTION WORKING DRAWINGS
This is the largest and most vital stage, and normally requires quite a lot of your input. We prepare the detailed drawings and specifications that allow your contractor to price the work and most importantly construct your project.
Typically, we will provide a 1:50 Scale Plan and Section Details (detailed instructions), 1:20 Scale Sections, Door and Window Schedules, Mechanical and Electrical Plans, Floor Finish Plans, and a detailed written specification.

The specification is often combined with the Building Regulations Specification to help the contractor understand the Building Regulation requirements. This work stage is normally undertaken as a percentage of the anticipated construction cost.
We are also able to perform interior design services (in-built furniture, kitchen design, shelving, fittings, internal elevations, sanitaryware design, tile layouts), which can be undertaken on an hourly rate basis.
COST CONTROL
You may wish to employ a quantity surveyor during the pre-tender stages to ascertain the likely construction cost, which can be undertaken at the sketch and planning stages.
Alternatively, the square-metre rate used for recent similar projects can also be a useful guide for construction costs. We normally work with quantity surveyors post planning and at the Building Regulations phase when more detail is known.
A quantity surveyor may also be beneficial when negotiating a price with a contractor, as they can prepare a breakdown of costs for you to compare. We have close relationships with a number of quantity surveyors and are able to organise and manage them for you.
TENDER PROCESS
During this work stage, we identify a number of contracting firms and invite them to tender. The contractors that are able to tender will then be sent the Tender Package and have five weeks in which to prepare their prices and submit their tender.
We normally shortlist two contractors, compare their costs, and invite them in for an interview. The winning contractor may be chosen based upon cost, start date, completion date, quality, and who you think you can work with. We will also make our recommendation to you. This work stage is normally undertaken as a percentage of the anticipated construction cost.
Tenders are becoming increasingly unpopular as many contractors are busy and prefer to work on a negotiated price, but can still be useful to test the market.
We suggest sending Tender Packages to a minimum of five contractors; however, we often find that we may only receive two tenders back. This means it can be difficult to make direct comparisons and be satisfied that the market has been truly tested.
