Harrow Architectural Design Process

1. Design

Here at Detailed Planning, we have a team of trained designers that are specialised in creating amazing spaces for all types of briefs. We understand the cost of developing a property, so we’re sensitive to our costs and guidance. We aim to help you stretch your money enough to get the best results! Read More Here

2. Get Approved

We are experts at obtaining planning consent in Harrow. If your house benefits from permitted development rights, we’ll complete the necessary drawing and documents to demonstrate your proposal falls within permitted development guidance. Should your house extension require planning consent, we can give you the best chance of planning consent by acting as your agent throughout the process. Read More Here

3. Technical

This is the stage where the detailed technical drawings are carried out by our design team. We believe in providing extra detail so your builder constructs your project with the quality it deserves. Remember, in order for a project to go accordingly, having a good, detailed set of drawings is crucial. Read More Here

4. Ready. Set. Go

At last! Your dream home is now ready to go under construction! This is all very exciting and you now have all the relevant drawings to hand. At this point of the project, we provide a continued support service, so feel free to call us whenever you like. All that’s left to do now is grab a cup of tea and relax!

Harrow Extension Case Study

This house extension project in Harrow exceeded our client’s expectations and created a space for their family to enjoy for years to come.

Excellent service. Paul is very thorough and took his time to make his decisions and explain them to me. He is friendly and helpful and has a ‘can do’ attitude.

Would definitely recommend for any detailed drawings required, we got them in late in the day to provide building regs drawings, were really efficient in completing within the required timescales and went into a lot of detail to make sure everything was right.

I felt in very capable hands and expertly advised. I’d highly recommend Detailed Planning. Our new loft conversion has maximised the space available to us. 

Why Choose Our Harrow Architectural Designer Services?

Understanding Your Project Goals

When we begin, we’ll take time to understand your brief; you may also have ideas of how your house extension will look. We’ll take this into consideration but also consider costs, planning constraints and buildability. There’s no point in designing something that can’t be built!

Striving to Create Quality Spaces

Our number one goal is to create spaces that meet requirements and go beyond the expectations of our clients. We love to hear that our clients are enjoying their new extension and this gives us the energy to go on.

Believe In Quality Design for Everyone

Good design should not be limited to some Architects only. We are here to provide excellent architectural environments to all, at a more realistic cost compared with some architect fees.

Pushing Technical Detail

Every house extension project is unique and ensuring it is buildable should be considered from the outset. Should we provide technical drawings, we’ll make sure risks on site are reduced by considering all parts of your project. This should lead to overall cost savings and minimised delays.

High Planning Success Rate

We never take on a project where the principle of the development seems unlikely to be approved. During the design, we’ll use our knowledge and check planning policies to give your application the best chance of success. We have worked with many authorities and understand how planning applications are decided.

Flexible Design Approach

We are not fixed to one design style; therefore we can be used for realist house extension design to ultra contemporary. We will listen to your brief and design a bespoke extension meeting your needs.

Architectural Services in Harrow FAQs

What Is The Difference Between an Architect and an Architectural Designer?

Something that gets asked often and can get mixed up is the difference between an architect and an architectural designer. The main difference between the two is that an architect is fully licensed and has earned their academic qualifications and license.

There is a rigorous 7-part registration exam administered by NCARB to complete to become an architect whereas architectural designers are non-chartered, partially qualified architects. It is important to do your research and browse around when choosing your architect to ensure that they offer exactly what you’re looking for.

What Does an Architect Do?

The role of an architect is the designing, mapping of detailed construction drawings and planning the construction phase. They must ensure that all their work is safe and functional for the people who will be using them. This could be for any building type but it is important to ensure that all work is completed to a high and safe standard.

What is the Process to Hire An Architect?

When it comes to hiring an architect, you will need to start with your planning application with your chosen architect and then sign a contract with them. Your contract should specify the work to be carried out and the project schedule or the renovation or work. You should also discuss your project plans and budget to not only make sure that it is achievable, but to get a clearer idea should your budget or plan be unattainable.

What Services Do Architects Offer?

As Harrow architects, our services usually include: concept design creation, construction document planning, and construction administration. Additional architectural services that we may provide can include: feasibility studies, architectural programming, and domestic project manager roles.

For more information regarding our architectural services, please be sure to give us a call today.

What Are the Important Questions to Ask Architects?

It’s never wrong to ask questions. In fact, the more you ask the more you’ll know and get to understand about your project. Some examples of the questions you may wish to ask or consider when choosing your architects include:

  1. Do you have any references or projects I can look at? – This will help you determine their skill, expertise, and how much more experience they have. 
  2. How long should I expect it to take to complete the project?
  3. What would be the start date of this? 
  4. Can I be helpful in any way during the project? 
  5. What are the other costs that need to be covered throughout the project? 
  6. Are there any limitations or issues that I should be aware of? 
  7. Ask your architect what they think of the project and if they have any suggestions – it could improve the final result or set your expectations straight.
  8. Ask the architect if they have professional indemnity insurance – it’s important to hold adequate insurance if anything should go wrong. 
  9. Ask your architect about the relationship with the contractor – it is important to know this as a good relationship won’t compromise design liability or the success of your project. 
  10. Who is your design team made up of? This will help you to understand who will be taking care of or involved in your project.
