Innovative Extensions Crafted with Exceptional Architecture


Our Soho architects create smart, sustainable extensions that suit your space perfectly.

Wraparound Home Extension

Wraparound


We specialise in wrap-around extensions. This is a popular way to expand and transform properties. This extension combines a rear and side addition. It creates an L-shape that expands ground-floor space. This is ideal for open-plan kitchens, living spaces, or adaptable rooms that fit modern lifestyles. We handle everything from design and planning permission to construction.

Single Storey Home Extension

Single Storey


A single-storey extension can really boost space in your Soho property. It can be added to the back or side of the property. This addition offers more space for a modern kitchen, a living area, or a home office. This extension improves the flow inside and makes the property more practical. Our architectural team makes it easy for you to get great results that suit your property.

Multistorey Extension

Multi Storey


A multi-storey extension in Soho can provide a lot of space. You can use it for extra bedrooms, bigger living areas, or more bathrooms. Building up on your property lets you make the most of it without losing any garden space. We take care of everything. This includes planning, permissions, and construction. We ensure your extension fits well with the current architecture.

Side Return Home Extension

Side Return


A side return extension utilises the unused space beside your home. You often find this addon in Victorian and Edwardian buildings in Soho. Clients can extend into this narrow area to make a wider, open-plan kitchen. This change will let in more natural light. Our architects are experts in side return extensions. These designs boost functionality and add to the property’s value.

Rear Home extension

Rear Extension


A rear extension expands the back of your property. This gives you room for an open-plan kitchen, a larger dining area, or a more spacious living room. This is ideal for clients looking to improve their ground floor. These extensions boost natural light and link indoor and outdoor spaces smoothly. We create rear extensions that match your home’s style. They also boost efficiency and value.

Seamless Home Extensions from Concept to Completion


Our team of architects, designers, and builders in Soho creates stylish and practical home extensions. We handle each stage, from the first meeting to the final build, with care and precision.

FAQ

An architect is required for extensions, as they deal with planning detailed drawings that are essential considerations.

Some individuals do entrust contractors with project design and construction, but this approach can come with risks.
Having an architect involved in renovations ensures that your home addition is compliant with regulations, although there’s no legal requirement to hire one for any project.

There’s no legal requirement to involve an architect in your application for your extension’s planning permission.

That being said, architects can be incredibly useful and save you a lot of time and money in the long run for moving your extension ahead.

While architects are not required to offer their services for free, we do not charge for an initial consultation. This initial meeting allows for a discussion about your project requirements. However, you should anticipate paying for any detailed design or advice beyond this initial conversation.

Typically, from engagement, we aim to produce draft documentation within a 14-day period.

Sustainable Extension Architecture Strategies in Soho

Soho, a vibrant and historic district in London, seamlessly blends culture, architecture, and community. The growing demand for property extensions highlights the need for sustainable architecture that respects Soho’s heritage while embracing modern development.

At Payte Architects London, we understand the unique balance required in this area. Our sustainable extension architecture strategies emphasise energy efficiency, sustainable materials, innovative design, community involvement, and green spaces — ensuring extensions enhance functionality and aesthetics while preserving the district’s historic charm.

Comprehensive Understanding of Extension Architecture

Extension architecture involves adding or modifying structures to expand living or working spaces. In Soho, where properties boast unique characteristics, well-designed extensions significantly enhance both functionality and aesthetic appeal.

Payte Architects London specialises in crafting thoughtful extensions that respect and complement existing architecture while aligning with Soho’s distinctive urban character.

The Critical Role of Sustainability in Extension Architecture

Sustainability minimises environmental impact and maximises efficiency in extension architecture.

In Soho, where tradition and innovation must co-exist, Payte Architects London ensures sustainable practices are at the heart of our designs — reducing carbon footprints, conserving resources, and promoting healthier environments.

Effective Strategies for Sustainable Extension Architecture in Soho

Our team at Payte Architects London applies a wide range of sustainable strategies — enhancing energy efficiency, selecting responsible materials, applying innovative architectural solutions, and engaging the community.

These methods reduce environmental impact and ensure extensions blend seamlessly into Soho’s historic urban fabric.

Enhancing Energy Efficiency in Extension Architecture

Energy efficiency is a cornerstone of sustainable design. Payte Architects London integrates technologies and materials that reduce energy use, improve thermal performance, and lower utility costs — ensuring long-term sustainability and comfort.

Implementing High-Performance Insulation for Energy Efficiency

We implement high-performance insulation tailored to heritage properties, using breathable natural materials to maintain character while improving comfort.

Our loft conversions and internal upgrades in Soho utilise innovative yet sympathetic techniques that meet both sustainability goals and conservation standards.

Upgrading to Energy-Efficient Windows for Enhanced Performance

At Payte Architects London, we incorporate energy-efficient windows designed to preserve the character of Soho’s heritage homes.

Our team often recommends heritage-style glazing with double or triple glazing to reduce energy loss while keeping in line with period aesthetics.

Installing Efficient Heating and Cooling Systems for Optimal Comfort

We install systems such as underfloor heating and air/ground-source heat pumps — ideal for discreet integration into extensions. Our space-efficient HVAC solutions reduce energy use and contribute to low-impact living in Soho’s compact properties.

Utilising Sustainable and Locally Sourced Materials

Payte Architects London champions the use of sustainable and locally sourced materials, aligning with both environmental standards and the visual continuity of Soho’s architectural legacy.

Choosing materials with a low carbon footprint supports both sustainability and authenticity.

Prioritising Local Sourcing for Sustainable Extensions

We prioritise local sourcing by specifying materials like London Stock Brick, sustainable timber, and reclaimed materials.

These not only reduce emissions but also harmonise beautifully with Soho’s architectural language.

Integrating Recycled Materials for Eco-Friendly Extensions

Recycled steel, aluminium, reclaimed timber and architectural salvage elements are increasingly integrated into our designs at Payte Architects London — creating characterful, environmentally conscious extensions that reduce landfill and celebrate sustainable innovation.

Embracing Innovative Design Solutions for Sustainability

At Payte Architects London, our innovative design solutions incorporate sustainability as a central principle.

We blend passive strategies with advanced construction methods to deliver forward-thinking, functional spaces within the tight constraints of Soho’s architecture.

Implementing Passive Design Strategies for Energy Efficiency

Passive solar gain, natural cross-ventilation, and daylight optimisation are integral to our designs. These techniques reduce reliance on artificial energy sources while creating a healthy, uplifting indoor environment.

Utilising Modular and Prefabricated Elements for Sustainable Construction

Modular components allow us to minimise on-site disruption in Soho’s narrow streets. Off-site construction and prefabrication offer speed, precision, and waste reduction — a forward-looking approach Payte Architects London uses to enhance sustainability and project efficiency.

Fostering Community Engagement in Extension Projects

We believe in collaborative, community-oriented design. Payte Architects London actively incorporates public consultation into extension planning to ensure community needs are understood and respected, supporting harmonious development in Soho.

Conducting Public Consultations for Community Alignment

Consultation sessions help our team align architectural proposals with local values. By fostering open dialogue, we promote community ownership and generate positive support for our sustainable designs.

Hosting Collaborative Design Workshops for Inclusive Planning

Collaborative workshops allow us to co-create solutions that reflect Soho’s cultural richness.

Payte Architects London believes that the best designs result from shared ideas and collective visioning.

Navigating Regulatory Frameworks and Policy Support

Our expertise in planning policy enables smooth navigation of Soho’s regulatory landscape. Payte Architects London supports clients through each stage — from applications to compliance — ensuring projects are efficient, lawful, and sustainable.

Securing Planning Permissions for Sustainable Extensions

With a deep understanding of conservation area guidelines, we tailor extensions to align with planning requirements while preserving architectural integrity. This precision reduces delays and enhances approval success.

Complying with Building Regulations for Safe and Sustainable Extensions

All Payte Architects London designs meet stringent building regulations, encompassing structural safety, energy efficiency, and indoor air quality — ensuring long-lasting, high-performing extensions.

Leveraging Government Incentives for Sustainable Extensions

Our team helps clients explore available incentives such as Green Homes Grants and tax relief schemes for energy upgrades. These options make sustainable extensions more accessible and cost-effective in Soho’s competitive property landscape.

Conclusion

At Payte Architects London, we bring deep local knowledge and sustainable innovation to every extension project in Soho.

By combining thoughtful design, advanced materials, and community collaboration, we help homeowners and developers create spaces that are functional, future-focused, and respectful of Soho’s heritage.
