Working With Homeowners

Nine Zero specialises in bespoke timber windows and doors for larger projects, collaborating closely with homeowners across London and the South West to ensure every detail is right from the very beginning.

Whether you’re building a brand-new home, adding an extension or carrying out a refurbishment, choosing the right windows and doors is one of the most important decisions you’ll make. The right products will have a significant impact on energy efficiency, security, long-term value and overall performance for decades to come.

Is Nine Zero the right partner for your project?

Our homeowner service is designed for people making a long-term investment in their property.

Typically, we work on projects such as:

  • Self-build homes
  • New-build residential properties
  • Extensions
  • Home refurbishments
  • Conservation property renovations
  • High-end residential developments

Many of our clients have already appointed an architect or designer before they speak to us. Others are introduced to us by the architect themselves, allowing us to become involved early in the project and help shape the right window and door specification from the outset.

Rather than simply manufacturing products, we become part of your wider project team, helping ensure your timber windows and doors complement both your property’s design and your practical requirements.

A collaborative approach from beginning to end


We work closely with everyone involved in your project, including architects, builders, and contractors, to ensure every aspect of your window and door package is considered. From confirming technical specifications and dimensions to discussing glazing, finishes, colours and performance requirements, we’ll make the process as straightforward as possible.

For larger residential projects, director-level involvement is also available, providing additional expertise and reassurance throughout the design and specification stages.

Understanding your vision


At the start of every project, our team will take the time to understand your needs, your property’s architectural style and what matters most to you. Perhaps you’re creating a contemporary family home filled with natural light. Maybe you’re extending a period property and want new timber windows that sit comfortably alongside the original architecture. Or perhaps you’re transforming a conservation property where maintaining character is just as important as improving thermal performance.

Whatever your goals, we’ll work with you to find the right balance between aesthetics, functionality, and long-term performance. Every timber window and door we make is made to order, allowing you to create a solution that feels completely at home within your property.

Keeping your project moving


We understand how important reliable communication and dependable lead times are. Our team works hard to ensure your project progresses smoothly, providing clear quotations, detailed specifications and realistic production schedules from the outset.

Our timber windows and doors are crafted in Cornwall by our expert team, allowing us to maintain exceptional quality while quickly delivering products that support your construction programme. Throughout your project, you’ll also have direct access to knowledgeable specialists who can answer questions, provide updates and ensure everything stays on track.
