What is the typical timeframe for architectural projects?

Most residential projects follow a predictable 5-6 month journey from initial survey through planning permission to building regulations approval. More complex projects or those in sensitive planning areas may require additional time, which we'll discuss during your initial consultation.

How much does architectural design typically cost?

Our services are structured into packages to accommodate different needs and budgets. The Foundation Service starts from £1,000 for straightforward extensions, while comprehensive packages for larger projects range from £2,000 to £10,000 depending on scale and complexity. We provide detailed fee proposals following initial consultations.

What areas do you cover?

We primarily serve Solihull, Birmingham, and surrounding areas of the West Midlands, with particular expertise in these local planning authorities. We have especially strong experience in Solihull neighborhoods including Knowle, Dorridge, and Balsall Common, and Birmingham areas including Moseley, Kings Heath, Edgbaston, and Harborne.

Do I need planning permission for my project?

Many projects can proceed under Permitted Development rights without full planning permission. During your initial consultation, we'll assess your property's specific circumstances including any constraints like conservation area status, previous planning conditions, or Article 4 directions that might affect your permitted development rights. We'll provide clear guidance on whether planning permission is required and the optimal strategy for your project.

What is the difference between planning permission and building regulations?

Planning permission concerns the appearance, size, and impact of your development, and is granted by the local authority planning department. Building regulations address technical performance including structural stability, fire safety, energy efficiency, and accessibility, ensuring the building is safe and compliant with national standards. Most projects require both planning permission (or permitted development confirmation) and building regulations approval.

How does your 3D visualization technology work?

We create detailed three-dimensional computer models using Building Information Modeling (BIM) software and advanced rendering tools. These visualizations can be explored on screen or through our Oculus Quest VR headsets during in-home design presentations, providing an immersive walkthrough experience. This technology helps clients understand spatial relationships that are difficult to comprehend from traditional drawings, leading to more confident decision-making.

Will you recommend builders for our project?

Yes, we maintain relationships with 15 quality-vetted builders throughout the West Midlands and can recommend contractors suited to your specific project. Our builder selection criteria includes at least 5 years' trading history, verified client references, appropriate insurance coverage, and demonstrated quality control processes. We can help manage the tender process to ensure you receive accurate, comparable quotes based on our detailed documentation.

What makes your architectural process different from other firms?

Our comprehensive 9-stage process includes unique elements like in-home immersive design presentations rather than office meetings, virtual reality walkthroughs instead of confusing blueprints, and face-to-face design evolution instead of email exchanges. We've achieved planning approval rates of 98% in Solihull and 93% in Birmingham through our deep understanding of local planning policies and requirements.

What are your core values and approach?

Our core values include: Comprehensive Expertise - providing end-to-end architectural solutions under one roof; Personalized Service - rejecting digital-only interactions in favor of face-to-face engagement; Technical Excellence - maintaining unwavering commitment to planning success and regulatory compliance; Visual Communication - using advanced visualization technology to help clients experience spaces before construction; and Local Knowledge - leveraging our deep familiarity with West Midlands planning authorities.

Benefits of First-Floor and Side Extensions

A first-floor or side extension from McTernan Design can significantly enhance your home’s functionality, visual appeal, and market value. Whether you need extra bedrooms, a modern bathroom, or a home office, our extensions offer the ideal solution for expanding your living space without compromising outdoor areas.

Increased Living Space: A first-floor extension provides additional rooms, ideal for growing families needing extra bedrooms or a new bathroom. A side extension can create an open-plan kitchen, dining area, or additional living room, optimising your home's layout and flow.
Enhanced Market Value: Adding extra space through a side or first-floor extension can significantly increase your property’s market value. Homes with spacious, modern layouts are highly sought after in competitive markets like Solihull and the West Midlands.
Improved Aesthetics and Integration: Our custom design process ensures that your extension seamlessly integrates with your home’s existing architecture, enhancing both its appearance and practicality. We work closely with you to create designs that complement your property’s style while meeting your needs.
Flexible Use of Space: First-floor and side extensions are perfect for creating multifunctional spaces such as home offices, playrooms, or additional guest rooms. This adaptability allows your home to evolve with your lifestyle, accommodating changing needs over time.
Remote Working Solutions: With the rise of remote working, a first-floor extension can provide a dedicated office space away from the main living areas, offering a quiet and productive environment.

Planning Permission for Side and First-Floor Extensions

Planning permission requirements can vary depending on your property's location, design, and existing constraints. McTernan Design offers personalised guidance on planning permission specific to Solihull, Birmingham, and the wider West Midlands.

Do I Need Planning Permission to Build Above My Garage? Generally, building a first-floor extension above a garage requires planning permission, especially if it impacts the external appearance or footprint of your home. We handle the planning process for you, ensuring that all designs meet Local Authority criteria and maximise the potential of your property.
Permitted Development Rights: Many side extensions can be carried out under Permitted Development Rights, especially if they meet specific size and design criteria. However, obtaining a Lawful Development Certificate is recommended to confirm compliance and avoid potential issues during future property sales.
Designated Areas: If your home is in a Conservation Area, Green Belt, or is a listed property, additional planning considerations will apply. Our team navigates these complexities, creating designs that respect local planning policies while delivering your vision.
