Earlier this month, I was asked to share my insights on the essential factors in designing, planning, and executing building projects in London. As an architect specializing in high-end residential design, I often guide clients through the complexities of budgeting, planning permissions, and sustainability considerations. Below, I’ve outlined key questions and my responses, which I hope will provide valuable guidance to anyone embarking on a new build, renovation, or extension.
1.What is the most important factor a client should consider, when planning for costs in new builds or renovations and extensions in London? i.e costs per square meter or planning permissions.
When planning for costs in new builds, renovations, or extensions in London, the most important factor a client should consider is comprehensive budgeting for all associated costs. This includes not only the obvious costs like construction and materials but also the often-overlooked expenses related to consultants and regulatory requirements. Here are some key points to consider:
Consultant Fees:
Before construction begins, clients should budget for various consultant fees, such as:
Measured Survey
Architect Fees
Planning Fees
Party Wall Surveyor
Structural Engineer
Fire Strategy
Asbestos Survey and Removal
CDM Advisor
Regulatory Costs:
Once construction starts, additional costs include:
Building Control Fees: These need to be appointed and paid by the homeowner.
Time Implications:
The time required for each consultant’s work and regulatory approvals can also impact the overall timeline and budget.
By accounting for these factors early in the planning process, clients can avoid frustration and disappointment later on. This comprehensive approach ensures that all potential costs are considered, leading to a more accurate and realistic budget.
Lastly, always have a contingency budget to cover unexpected costs that may arise.
2. Pre-Application Advice: Are the costs the same compared to different areas of London for similar types of builds?
While the costs for planning and pre-planning advice are generally consistent across London, the ease of obtaining planning permission can vary significantly. In some areas, pre-planning advice is mandatory, adding both time and cost to the project. Conversely, other areas may not require this step, making the process quicker and potentially less expensive.
3. If the planning takes time to be granted, what should a client keep in mind regarding costs?
Clients should carefully plan the timing of their project to avoid overlapping costs. For instance, if they need to rent accommodation while construction is ongoing, this can add to their expenses if booked in advance with a very strict date in mind. Some tasks, like technical drawings, tendering, and structural or party wall agreements, can begin while waiting for planning permission. However, if the project is complex and planning permission is uncertain, additional time may be needed to amend the project. This can result in more hours billed by consultants and other professionals, as well as the risk that contractors may not be available to adjust to a new start date or timeline.
3. Unique Challenges in London: What are the unique challenges of obtaining planning permission in conservation areas or for listed buildings in London? Are there major pitfalls that clients can avoid?
Conservation Areas are designated for their special architectural or historical interest. Any proposed changes must preserve or enhance the area’s character. Listed Buildings are legally protected due to their historical or architectural importance. Any alterations require listed building consent, which ensures that changes do not harm the building’s historic fabric among others.
Some aspect that are specially important:
Materiality: Traditional materials that match the original construction are often required. This can include sourcing period-specific bricks, timber, and roofing materials to maintain the building’s authenticity.
Architectural Integrity: Proposed alterations must respect the original architectural style and features. Modern additions should complement the existing structure rather than overshadow it. Consultation and Public Engagement: Extensive consultation with planning authorities, conservation officers, and sometimes the public is often required. This ensures that all stakeholders are on board with the proposed changes.
Trees and Greenery: Trees on the property may be protected, and the property might fall under a Tree Preservation Order (TPO), making it mandatory to preserve or replant them. This might also require a tree specialist consultant during the planning stage, potentially incurring additional costs.
Major Pitfalls to Avoid:
Ignoring Local Planning Policies: Each local planning authority (LPA) may have specific policies and guidelines for conservation areas and listed buildings. Ignoring these can lead to delays or refusals.
Inadequate Documentation: Failing to provide detailed plans, heritage impact assessments, and justifications for the proposed changes can result in applications being rejected.
Underestimating Costs and Time: The process can be more time-consuming and costly than standard planning applications due to the need for specialist materials and expertise.
Lack of Professional Advice: Engaging with architects and consultants experienced in heritage conservation is crucial. They can navigate the complexities and ensure that proposals meet all necessary criteria.
By understanding these challenges and avoiding common pitfalls, clients can better navigate the planning permission process for conservation areas and listed buildings in London. If you have any specific scenarios or further questions, feel free to ask TUB Architects.
4. Unique Approach to Design: What sets your architectural firm apart in terms of design philosophy and approach to design? Can you share any success stories or case studies?
At TUB Architects, we excel in residential projects, focusing on spatial design, storage optimization, and maximizing natural light. Our mission is to transform houses into timeless, functional, and beautiful homes that cater to our clients’ needs for years to come.

5. Sustainability Practices: How does your firm incorporate sustainability and environmental considerations into your projects, particularly in the context of urban extensions?
Given the constraints of working with period houses, often in conservation areas, we prioritize preserving the original character of the buildings while implementing improvements where possible.
To reduce our carbon footprint, we incorporate several measures, including:
Adding insulation to external walls.
Installing a new roof during a loft conversion to meet the latest regulations
Installing underfloor heating
Using heat pumps instead of boilers
Implementing Sustainable Urban Drainage Systems (SUDs) to reuse rainwater and prevent overloading public sewage systems
Utilizing high-efficiency appliances and electrical items
Installing smart thermostats to optimize heating times and zones
Employing energy-efficient lighting
Replacing faulty windows and doors to prevent air leaks and install double/triple glazed windows and doors that perform much better.
These steps help us make the buildings more efficient and environmentally friendly while respecting their historical significance.
Designing, planning, and executing a building project in London comes with unique challenges, from budgeting and regulatory approvals to planning permissions in conservation areas. By understanding these complexities and working with experienced professionals, clients can navigate the process with greater confidence and clarity.
