Two-storey Extensions

A two-storey extension is an efficient way to add significant space to both floors of your home. Most two-storey extensions are designed to create an additional bedroom accessed from the existing landing, often with an en-suite, and to enlarge the kitchen or provide a new utility room, downstairs toilet, or home office on the ground floor.

How We Can Help

We provide detailed architectural design plans for two-storey extensions, tailored to meet your needs and the specific layout of your home our comprehensive plans including
everything required for covering everything needed for building regulations approval and accurate construction pricing.

Because most two-storey extensions require formal planning applications, we manage the entire process for you—from preparing and submitting documents to liaising with planning officers and making any necessary amendments to support approval.

With years of practical experience and in-depth knowledge of local planning policy, we deliver clear, buildable plans that meet both building control approval standards and homeowner expectations.

Choose Your Extension

Looking to expand your home? Whether it’s extra bedrooms, a spacious open-plan kitchen, a practical utility room, or a dedicated home office, we’ll help you make the most of your space. We take the time to understand your vision and lifestyle needs, offering guidance on the type of extension that will add both function and value to your home. No two projects are the same, your goals shape our approach.

Consultation

Site Survey

At this stage, we’ll begin with a comprehensive site survey to gather accurate measurements and identify any site-specific constraints. This ensures we can produce precise plans that meet planning and building regulation requirements. The survey also helps us fully understand the physical context of your property. Once complete, we’ll have a detailed discussion about your goals and preferred layout, allowing us to shape the initial set of drawings to closely match your vision and project requirements from the very beginning.

Provisional Design

After the site survey and initial consultation, we’ll begin work on your provisional design, tailored to your requirements and the information gathered on site. This first set of drawings will include detailed existing and proposed floor plans and elevations, offering a clear overview of the planned changes. The design process is flexible, allowing your ideas to evolve as you review the plans. Once shared with you, we’ll take your feedback on board and make any necessary amendments, working closely with you to refine the drawings until you are completely satisfied with the final design.

Finalising the Plans

Once the design is finalised, we’ll proceed based on your project’s needs. If planning permission is required, we will prepare and submit the full application on your behalf, managing all communication with the local planning authority and making any necessary amendments. If planning is not required, we will produce detailed Building Regulations drawings. These include all the technical specifications needed for Building Control approval and for builders to provide accurate quotations. They also serve as construction drawings, guiding the build on site and ensuring the work complies with current building regulations.

Project Support

Our involvement continues beyond the approval of your extension plans and the start of construction. We remain available throughout the build to respond promptly to any queries from Building Control regarding compliance, ensuring your project proceeds without unnecessary delays. We also provide ongoing support to your builder should any questions arise on site. In some cases, unforeseen conditions may be uncovered during construction that require minor design adjustments. When this occurs, we are on hand to offer timely, practical solutions to keep the project progressing smoothly and in line with regulations.
