Design and Planning Permission

When considering a home extension, it’s natural to feel uncertain about design ideas. We understand these concerns and are here to simplify the process. Our team collaborates with you to transform your vision into a tangible design, addressing any apprehensions you may have. Are you worried about aesthetic cohesion or functionality?

Rest assured, we will help with your designs that not only meet regulations but also enhance the beauty and practicality of your home. With a diverse portfolio and a commitment to client satisfaction.


Navigating Planning Applications:

Planning applications are a pivotal aspect of any home extension project, requiring careful consideration and adherence to local regulations. In Edinburgh, the approval process involves compliance with specific zoning laws and regulations. New Haven Building Company, with its extensive experience, guides clients through this intricate process, ensuring that their proposed extensions meet all legal requirements. By navigating the complexities of planning applications, we help clients avoid delays and ensure a smooth transition from the planning phase to the construction phase.

Understanding Local Regulations:

Edinburgh’s local regulations play a significant role in shaping the planning and design of home extensions. It’s crucial to comprehend and comply with these regulations to ensure the successful approval of the proposed project. We don’t expect you to know all the ins and outs of this subject and the changes that happen over time. That’s why you come to us, so we can lead the way.

Minimising Pitfalls:

The planning phase can be rife with potential pitfalls. By leveraging our experience, we can proactively address potential issues that could lead to planning rejections or costly revisions. This risk mitigation strategy enhances the likelihood of a successful planning application and contributes to cost savings by avoiding common pitfalls that may arise during the construction process.

Communication with Local Authorities:

Effective communication with local authorities is paramount during the planning phase. Not all planning applications are straightforward and negotiating with local authorities to address concerns and fulfil specific planning requirements can be required. Acting as a liaison between clients and regulatory bodies can contribute to the smooth progression of the planning application.

When contemplating a home extension, understanding the costs involved is crucial for effective planning. Key considerations include:

1. Size and Complexity:

The scale and intricacy of the extension significantly impact costs. Larger or more intricate designs often require more resources and labour, influencing the overall expense.

2. Materials and Finishes:

The choice of materials, fixtures, and finishes plays a substantial role in cost determination. High-end materials typically result in a higher overall budget.

3. Design Complexity:

Unusual or intricate designs may require specialized architectural or engineering expertise, affecting costs. Simpler designs are generally more cost-effective.

4. Location:

Regional variations in labour and material costs can impact the overall budget. Understanding local market rates is essential for accurate cost estimations.

5. Planning and Permissions:

Costs associated with obtaining necessary permits and complying with local regulations should be factored in. Professional guidance in this area can help streamline the process.

6. Project Management:

Consider the need for project management services. Professional project management ensures efficient coordination, potentially saving both time and money.

7. Contingency Fund:

It’s advisable to allocate a contingency fund for unexpected expenses or changes during construction. A contingency helps manage unforeseen challenges without compromising the project.

8. Accessibility:

The accessibility of the construction site can impact costs. Limited access may require additional equipment or labour, contributing to the overall budget.

9. Timeline:

The duration of the project influences labour costs and other associated expenses. Faster timelines may incur additional costs but could result in overall savings.

10. Quality of Construction:

Investing in high-quality construction is essential for the longevity and value of the extension. Cutting corners on construction quality may lead to long-term issues.



1. Unforeseen Structural Issues:

Hidden structural problems discovered during construction can lead to unexpected expenses. Conducting a thorough pre-construction survey can help identify potential issues in advance.

2. Changes in Design or Scope:

Alterations to the original design or the scope of the project mid-construction can significantly impact costs. Carefully finalise the design before commencing construction to minimize changes.

3. Poor Planning:

Inadequate planning, including inaccurate initial cost estimates, can overrun budget. Engage professionals for detailed and realistic cost assessments from the outset.

4. Unexpected Site Conditions:

Unforeseen site conditions, such as poor soil quality or drainage issues, can necessitate costly adjustments. Conducting a site analysis before construction can help anticipate and address these challenges.

5. Price Fluctuations:

Fluctuations in the cost of materials and labor can impact the overall budget. Consider locking in prices with suppliers and contractors to mitigate the risk of cost increases.

See What Our Customers Are Saying

Had a very good experience with Ross and his team. They did an excellent job relocating our kitchen, transforming our dining room into a kitchen-diner and creating a new study where our old galley kitchen was. The job involved some tricky drainage and pipe work, which they carried out without a hitch.

They also fitted a fantastic new wooden floor throughout the study, kitchen-diner and extending right through the hallway, which looks and feels great. I particularly appreciated that they managed to do this all within the original timescale for the job because the floor was a bit of a late request from me after work had already started.

Without exception the work Ross and his team have done for us has been of a high quality and very reasonably priced. Communication was also good. Unlike some other companies I have dealt with he actually gets back to you. Overall I would definitely recommend New Haven Building Company for any kind of home renovation work.

Alan W

Newhaven Building Company recently completed a garage conversion for us. The work was completed well ahead of schedule, within budget and we’re delighted with the results. Ross and his team did a great job, kept us updated throughout and also went to great lengths to minimise mess and disruption both inside and out (to the point that some neighbours pointed out how tidy they are!).

Every aspect of the work was covered by Newhaven, so we had no need to involve any other tradespeople ourselves. I’d also not hesitate to recommend all the other guys Ross had involved in the work…roofer, painter, electrician, plasterer, carpet fitter….all were great.

The end result is a full finished garage conversion exactly as we’d hoped for. I wouldn’t hesitate to recommend Newhaven Building Company to anyone.

Richard Brown

I just wanted to say how delighted we are with the work that Ross and his team have done. Knocking down a conservatory, making a new sun room and transforming our kitchen and dining room into one amazing light space.
They were such quick and efficient at the work and it was completed well ahead of schedule. Ross and his team are such hard workers and really professional. Ross project managed the whole thing so it was seamless from start to finish. They were so tidy despite the disruptive work they were doing and very reliable.
I wouldn’t hesitate to recommend them to do any building work and think you would be daft to go anywhere else!!
