Extension Checklist 

14th March 2024

Have you been looking at starting an extension project at your home? Do you know where to start? Have you read up on all the nuances associated with getting an extension added to your home? More than likely, you have read hundreds of articles that vaguely tell you little bits and pieces you need to know without giving you a full-rounded idea of what an extension project should look like. 

Our team here at Detailed Planning have been offering extensions to homeowners across London for several years; during this time, we have seen all the issues homeowners come across, generally before they come to us after issues with other companies. 

One of the most important things to our team is that we can offer you a clear and concise brief of how to manage your extension project; it is supposed to be an exciting and fun time expanding your home; let our team at Detailed Planning provide you with everything you need to ensure a smooth process. 

Establishing A Clear Brief 

The significance of providing architects with a clear brief cannot be overstated, as it serves as the foundational blueprint guiding the entire architectural project. This brief should encompass the client’s aspirations, functional requirements, and specific design preferences and constraints. 

Key elements that are imperative to include within the brief include the project’s objectives, desired outcomes, space and usage requirements, stylistic preferences, sustainability considerations, and budgetary limitations. 

By articulating these critical components, clients can ensure that architects have a comprehensive understanding of their vision, enabling the creation of a design that is not only aesthetically pleasing but also functionally and economically viable.

Gathering Existing Property Information 

Understanding the constraints associated with a property is a crucial initial step in any architectural project. These constraints include legal restrictions, covenants imposed on the property, and any plans that detail previous developments or alterations. 

To gather this essential information, clients should thoroughly review property deeds, consult local planning authorities, and, if available, access historical building plans. Once collated, this information should be meticulously organised and provided to the architect. 

This comprehensive understanding of the property’s limitations and potential informs the design process and helps navigate legal and regulatory frameworks, ensuring the proposed developments are feasible and compliant. 

Setting A Realistic Budget 

Establishing a clear budget is paramount in architectural projects, as it dictates the design and construction’s scope, materials, and complexity. A realistic budget ensures project aspirations align with financial constraints, preventing costly overruns and delays. 

To set a viable budget, clients should consider all potential expenses, including materials, labour, professional fees, and contingency funds for unforeseen costs. Conducting market research and obtaining preliminary quotes to gauge average costs is also advisable. 

Communicating this budget transparently with your architect and construction team is crucial; it enables them to tailor designs and proposals that respect financial boundaries while striving to meet project objectives. 

Open and ongoing dialogue about the budget throughout the project can help manage expectations and facilitate necessary adjustments promptly.

Collaborative Design & Development 

The collaborative synergy between clients and architects during the design and development phase holds immense value, as it lays the foundation for a project that truly reflects the client’s vision while harnessing the architect’s creativity and expertise. 

Engaging closely with your architect, sharing ideas, and providing feedback ensures that every design aspect is considered and refined. Allowing ample time for this process and avoiding the urge to rush decisions is crucial. 

A thoughtful, unrushed approach facilitates a deeper exploration of design options, innovative solutions, and careful consideration of functionality and aesthetics. 

This collaborative journey enriches the design outcome and fosters a sense of shared ownership and satisfaction in the final project.

Navigating Planning Permissions 

Navigating planning permissions is a critical aspect of any construction or renovation project, serving as a regulatory framework to ensure that developments adhere to local planning policies and guidelines. 

The importance of obtaining these permissions cannot be understated, as they validate the legality of the project, helping to avoid potential legal complications and ensuring that the development is in harmony with community standards and infrastructure capabilities. 

The process typically begins with a thorough assessment of local planning requirements, followed by preparing detailed plans and documents that outline the proposed development. 

These are then submitted to the local planning authority for review. Engaging in pre-application discussions can provide valuable insights and increase the likelihood of approval. It’s essential to monitor the application’s progress and be prepared to respond to any queries or requests for additional information. 

Securing planning permissions is a pivotal step that paves the way for a project to proceed with confidence and compliance.

Engage With Your Builders & Conduct A Technical Phase 

Early engagement with builders is paramount in ensuring the seamless execution of your project, as it allows for the integration of practical construction insights and cost considerations into the design phase. 

To shortlist potential builders, focus on their previous work quality, reliability, financial stability, and client testimonials. Once shortlisted, the technical phase becomes crucial, requiring meticulous attention to building regulations, structural calculations, and detailed specifications to ensure safety, sustainability, and compliance. 

It’s also essential to understand and address party wall agreements if your project impacts adjoining properties and to familiarise yourself with building control requirements, which ensure that the construction meets national standards. 

Navigating these aspects effectively lays a robust foundation for your project, minimising the risk of delays and ensuring that the build is conducted to the highest standards.

Manage Any Planning Approval Conditions 

Managing conditions included in the planning approval is essential in moving your project forward post-approval. These conditions often specify adjustments or additional details required to comply with planning policies. 

To address these, meticulously review each condition and prepare the documentation or modifications that respond directly to the stipulations. This may involve detailed drawings, material samples, or specific construction methodologies. 

Once prepared, these responses must be submitted to the local planning authority for final approval, ensuring that all conditions are met satisfactorily. Maintaining open communication with the planning officers is advisable, as well as seeking clarification and guidance as needed to ensure your submissions align with their expectations. 

Successfully managing and fulfilling these conditions demonstrates compliance and facilitates a smoother transition to the construction phase of your project.

Finalise Contracts And Start Your Project 

Finalising the contract with your chosen builder is a pivotal moment that marks the transition from planning to action in your project. Ensuring the contract meticulously outlines the scope of work, timelines, payment schedules, and any specific terms agreed upon to safeguard both parties’ interests is critical. 

Before signing, a pre-project checklist should be diligently reviewed to confirm that all necessary approvals, including planning permissions, building regulations, and other relevant consents, are securely in place. 

This proactive approach prevents potential legal or procedural setbacks once construction commences. By thoroughly addressing these prerequisites, you set a solid foundation for your project to proceed smoothly, with clear expectations and a structured framework guiding the path forward.

Site Inspection And Completion Certificates 

Site inspections play a crucial role in maintaining the quality and integrity of a construction project, serving as regular checkpoints to ensure that the work conforms to the plans, building regulations, and quality standards. 

These inspections, conducted by either a building control body or an approved inspector, allow for the early identification and rectification of any issues, ensuring the project’s smooth progression. A completion certificate is issued upon the successful completion of the project and satisfactory final inspection.

This certificate is a vital document that confirms the project has met all the necessary building control standards and regulations, signifying that the project is compliant and safe for occupancy.

Obtaining this certificate is a crucial final step in the construction process, marking the project’s formal conclusion and allowing it to be used or occupied as intended.
