Stage 0-1:

Site Investigation, Client Brief and Measured Survey:


Measured surveys are essential for projects involving existing buildings. Accurate drawings are crucial for informed decision-making and effective design. The measured survey serves as the foundation for all subsequent drawings.

The survey records building information included plans, elevations, key heights, and dimensions, encompassing ceiling heights, stairs/steps, windows, and door sizes, resulting in a precise set of drafted CAD (computer-aided-design) drawings.

We conduct a thorough site evaluation, gathering all relevant information, including planning history, homeowners’ surveys, underground utilities, sewerage services, and any existing property issues. This comprehensive assessment ensures a complete understanding of the site, allowing for informed decisions throughout the design and construction process.

Following the site survey, we collaboratively create a comprehensive client brief that encapsulates your unique needs, preferences, and aspirations for your new extension, remodelling, renovation or interior layout modifications. This document serves as the cornerstone of the design process, ensuring that every proposed design aligns with the vision for your transformed home.

Stage 2-3:

Scheme Design with Planning Application:


This stage fosters a continuous feedback loop between us, the architects, and you, the homeowners, as we work together to refine and collaborate on a design that aligns with your needs and aesthetic preferences. We strive to present two to three distinct design options, each thoughtfully responding to your brief, the existing house, and the unique characteristics of the site.

We provide outline cost estimates and assess whether a planning application is necessary or if the project falls under homeowner permitted development rights. We prepare clear, high-quality drawing packages for Planning Application Submission, effectively conveying the proposed project while showcasing the home extension or renovation design quality. When required, we create compelling Design and Access statements in support of the Planning Application and complete all necessary forms and documents for submission.

With over a decade of experience with Bath, Bristol, Wiltshire, and Somerset Planning Departments, our extensive expertise ensures that your project meets all regulatory requirements. We also assist with Lawful Development Certificates and Conservation Area Consent applications.

Stage 4:

Building Regulation Drawings (“Light Technical Drawings”):


To guarantee that the proposed works adhere to all applicable Building Regulations, we prepare the necessary drawings for submission to Building Control. This technical package provides essential detailing information to facilitate construction and ensure compliance with current Building Regulations. It is well-suited for “typical or standard works” that do not involve unconventional materials, design features, or elements.

Building Control Approval can be obtained through either “Full Plans” or “Building Notice.” For all but the most minor projects, the “Full Plans” method is strongly recommended. This comprehensive drawing package serves as a valuable tool for obtaining contractor/builder quotes as it provides an outline of the project’s construction methodology.

Construction Details/Technical Drawings:


These drawings provide a more comprehensive guide to the building’s construction, empowering contractors to navigate the  “junctions” of the structure and ensure the highest quality of finishes in critical areas.

It creates specific details for the roof edges, cladding, windows details, thresholds and more. These drawings are essential for elements that deviate from standard construction practices, such as timber cladding, flush thresholds, green or zinc roofs, large dormers, special windows, or timber structures.  We draw these details to precisely convey the assembly of these building materials and elements, facilitating a swift and efficient construction process on-site.  This comprehensive approach is recommended for all projects, except for the most straightforward ones.

For enhanced cost certainty during the quoting process, we can provide a comprehensive Specification/Schedule of Works, delving into even greater depths of detail.

CGI – Architectural Visualisations and VR:


Enhance your understanding of the project’s scale and spatial arrangement before construction begins with our architectural visualisation service. We can simulate sunlight to allow you to visualise the light within the space. Additionally, we can provide renderings of the spaces and potential furniture layouts to aid in your design decisions. External renderings are also available, showcasing the impact of the construction and extensions on the overall property. This service is particularly beneficial for clients seeking confirmation of the spaces’ appearance and feel before construction commences.

This optional three-dimensional service is offered to all our homeowner clients who require design assistance, as it facilitates effective communication and design development. We can produce multiple images throughout the design process to ensure clarity of discussion and decision-making.

For an even more immersive experience, we offer Virtual Reality (VR) modelling with headset presentations. This allows clients to virtually walk through the proposed space, exploring it from various angles and gaining a clear sense of scale and proportion. The fully furnished VR models provide a realistic representation of the finished space, enabling clients to truly envision their dream home.
