We practice a Strategic Home Design, which focuses on how to lower build cost while maximising light and space.

The main component of strategic home design is "good design". Good design is the key to lowering building costs, while maintaining a high quality build. Where good design is concerned cheap is not cheerful. If you know what you want and just need someone to draw it up cheaply for you then we are not the right company for you.

We have been to thousands of homes in over 19 years of professional experience. We know what designs work best and will show you creative ways to save while building your dream home.

We offer you 3 design options with unlimited changes prior to planning permission as standard.

We have a very high planning success rate, so most of our planning applications are approved.

We are cost conscious and can design to suit your budget.

Give us a call and experience our revolutionary design service and reasonable fees for yourself.

Review of Siproj Architecture by Ernest Evwaraye

I found Siproj to be very creative and flexible. I have used them twice now- once for a new kitchen and also to refurb my basement space. Both times they were able to produce stunning results within my budget. Really impressed with how they were able to create extra space in my home through their excellent redesign work. They saw potential that i couldn't see. Would definitely recommend!

We had a considerable extension built into the back of our house. Siproj Architecture dealt with all aspects of drawing up the plans and planning permissions. The extension is fabulous. Better than we could have hoped. We are very happy with the professional and friendly service that Siproj architecture provided

Review of Siproj Architecture by Ruth Cain

This person (it is one woman, Igho Tabor, not a firm) has been disbarred from the ARG and RIBA for professional misconduct but continues to trade as an architect. To call her unprofessional would be an understatement; she failed to complete work on her contracted project with me which required significant remedial work, forced the issue to RIBA arbitration, provided a lot of personal abuse during the process including comments to the arbitrator on my housekeeping and parenting, and blamed me for the entire situation. She employs 'contractors' who are beyond incompetent and cannot even hang a blind. They also drank all the alcohol in my house and broke a lot of things. Luckily RIBA found against her in the matter, although at that point allowed her to produce a few 'expenses' she had not previously claimed. She also then failed to provide the payment required by RIBA until I threatened her with a court action. I see that other clients obtained CCJs against her and went unpaid. She continued to tell lies about being a broke 'single parent' (she is not) even at her misconduct hearing, the details of which are available online. This woman is an out and out fraud and blames everyone else for her own incompetence. I am glad to see that she has since been disbarred, as I wouldn't want anyone else to have to go through her nonsense. It's a significant concern that she is still practicing. AVOID OR YOU WILL REGRET IT.

The reviewer above is my son's friends' mother, so I'm limited in my response. The piece above cannot really be classified as a review, but rather as a Statement of Hate. If you are interested in using my architectural design services, and take advantage of 18 years of experience in residential design and our 95% planning success rate, I strongly recommend that you ignore the above statement of hate and speak to me directly. Trust in your inherent ability to decide what is good for you.

Igho was the first and very prompt to respond to my posting. She was equally enthusiastic and had great ideas for our project when she visited . She was very clear about the whole process and the fees.

The director of the firm - who is also the firm's architect- recently visited us to discuss design options. Her ideas are exciting and innovative and she came across as an enthusiastic, honest and committed person and her company's fees are reasonable. She made it clear that she is interested in ' smaller' projects so we knew exactly where we stood with her from the outset.
If you are looking for somebody who has artistic flair then this is the person for you.
