Department of Architecture

The department of Architecture was formally established during the 2008/2009 academic session as one of the four foundation departments of the College of Environmental Sciences. It set out to provide a two-tier training programme in Architecture in line with existing training paradigm in Nigeria leading to the award of Bachelor of Science and Master of Science Degrees respectively.

The department took off with the first tier five-year Bachelor of Science programme in the 2008/2009 academic session with an initial enrolment of 19 students under the headship of Dr. Olusegun Oriye and supported by a couple of other Architects. From the initial enrolment of 19 students at its commencement in 2008/2009, the students’ population has grown to one-hundred and seventy five in 2015/2016 at the department.

Over the eight years of its existence, the department has continuously enjoyed full accreditation and re-accreditation by both the National Universities Commission (NUC) and the Architects Registration Council of Nigeria (ARCON) for the Bachelor of Science degree programme. Three sets have been graduated from 2012/2013 to 2014/2015 with the certification of ARCON Jurors each year. The department has thus established a B.Sc. programme in Architecture with full academic and professional accreditations.

Just recently, both the NUC and ARCON approved a new four year curriculum for the B.Sc. programme which has come into effect from the 2015/2016 session with the new intakes for the session.

The humble progress made by the department thus includes:

1. Resource verification visit and approval by the National University Commission.

2. Accreditation of the Architecture B.Sc. programme by the NUC.

3. Accreditation of the Architecture B.Sc. programme by the NIA/ARCON.

4. Resource verification visit for the Architecture M.Sc. programme by the NUC.

5. Resource verification/accreditation visit for the Architecture M.Sc. programme by NIA/ARCON.

6. Accreditation of the Architecture M.Sc. programme by ARCON.

7. We have had the NIA/ARCON Jurors visit us twice. The department has in place the Architecture B.Sc. programme that is accredited both by the academic NUC and the professional NIA/ARCON regulatory bodies. In addition, it has secured the approval of the NUC and ARCON to commence the Architecture M.Sc. programme.

8. It has graduated five sets – 2012/2013, 2013/2014 and 2014/2015, with its first class award in 2014/2015. We have put in place a department that was the first private university in Nigeria to have the NUC accreditation at the first go and the second university in Nigeria to achieve same. The department of Architecture has created good reports with both academic and professional regulatory bodies.

9. The department commenced the M.Sc. programme in 2014/2015 academic session.


Departments of Building and Quantity Surveying

The department of Building and Quantity Surveying was established in October of the 2009/2010 academic session. It runs two programmes.

1. Building, B.Sc. started with five students. In the 2010/2011 academic session, nine students were admitted and two were enrolled in 2011/2012 session. In the session 2012/2013, two students were admitted by direct entry to join the class of the existing students enrolled in 2011/2012 session at 200 level. Eight students enrolled at 100 level in the 2012/2013 academic session.

2. Quantity Surveying, B.Sc. was established in 2009/2010 academic session. It started with four students. In the 2010/2011 academic session, three students were admitted while a student was enrolled in 2011/2012 session. In the 2012/2013 academic session, three students enrolled at 100 level.

Building and Quantity Surveying

The department is planning to make the programmes relevant to the economic development of Osun State and Nigeria in general. New initiatives are being planned in collaboration with the department of Building and Quantity Surveying of other universities, especially Obafemi Awolowo University leading ultimately to an academic excellence.

The pioneer Head of Department was Dr. A. F. Lawal in 2009 to 2013. This immediately followed by the appointment of Bldr. B. Fasuyi from 2013 to 2015 and then by Dr. P.O. Lawal as the HOD from 2015/2016 till the end of 2016/2017 session.

Dr. P.O. Lawal also coordinates the seminar programme of the department. The HOD is assisted by course advisers.

Decisions are jointly made by the Head of department and other members of staff. To achieve this, staff meetings are called regularly to deliberate on critical issues pertaining to the smooth running of the department.

The two academic programmes within the department aim to develop and produce competent practicing construction professionals. In addition, students will be equipped with the right skills, knowledge, understanding, and attitude necessary to effectively practice, eventually providing efficient and effective manpower for the building  industry nationally and internationally.

Department of Estate Management

Estate Management, B.Sc. was introduced in 2008 under the College of Environmental Science leading to the establishment of a full-fledged Department of Estate Management for the 2008/2009 academic session.

The Department has since its establishment offered undergraduate programme in Estate Management. The department considers its abiding duty to be that of providing a sound education in Estate Surveying and Valuation discipline, such education is intended to satisfy the need of varied classes of candidates whose services may be needed by the public, as well as the private sectors.

As a study of the use, management, and development of land and other natural resources, the general philosophy is to optimize the use of land among competing claims having regards to public good, fair share by current owners of interest in the land and facilitate economic development.

Moreover, graduates in the discipline are exposed to the fundamental principles of economics, valuation, land law, law of tort, law of contract, building construction, surveying, account, architectural graphics, town and country planning, management and computer studies (to increase the ICT  base of the students).

The Department started with three academic staff in 2008 and an enrolment of ten (10) students. By 2012/2013 session, the Department had grown in size to 49 students and nine (9) academic staff of which two (2) are professors, and the other seven (7) are senior Lecturers, Lecturer I, Lecturer II and Assistant Lecturer.

Over the past eight years, Estate Surveying and Valuation Department has continuously fully enjoyed accreditation and Re-accreditation by both the National Universities Commission (NUC) and Estate Surveyors and Valuers Registration Board of Nigeria (ESVARBON) for the Bachelor of Sciences Degree Programme.

Estate Management

In its continuous implementation of the mandate, the department has graduated five sets (2012/2013 Session, 2013/2014 Session and 2014/2015 Session, 2015/2016 session, 2016/2017session with the certification of ESVARBON and NUC.

The Department has with this feat fully established a B.Sc. Programme in Estate Management with full academic and Professional accreditations.

The gallant academic products from the department are doing well in their respective fields both academically and professionally.

The intention of the department is to train Nigerians and non-Nigerians to a level of acquiring sound academic and professional excellence. The five-year degree programme aims at equipping students with institutional, analytical, and management tools with which our towns and cities can utilise their land resources for sustainable development.

At the moment, the quality of academic has improved as more academics and professionals are showing deep interest in the actualization of the vision of the department at large.

The department, from its initial enrollment of 10 students at the start of the 2008/2009 academic session, rose by 95 in the 2015/2016 academic session. An academic proposal to float a Master of Science degree in Estate Management, as well as a Doctor of Philosophy programme in Estate  Management has been submitted to the Academic Planning Unit for implementation.
