There are a few key factors you need to consider to determine whether your property will be suitable for a loft conversion. Firstly, you need to measure the height of the roof space.

1. Quality Loft Conversions in North London
Many homeowners are choosing to convert their loft space into additional living
space and to maximise the equity in their home, but how do you know if your home
is suitable for a loft conversion, and how do you go about making the most of the
space available? Our quick guide to loft conversions gives you the vital information
you need to make the right decisions…
Is my property suitable for a loft conversion?
There are a few key factors you need to consider to determine whether your property
will be suitable for a loft conversion. Firstly, you need to measure the height of the
roof space. You need around 2.3 metres (approximately 7ft 6in) to allow enough
headroom. The steeper the ‘pitch’ of the roof the better – a steeper roof will allow for
more headroom. If you don’t have enough headroom in the existing space it may be
possible to raise the roof or ceiling, although this is obviously subject to planning
consent and will increase the cost of the project. You’ll also need to consider
windows. Velux® windows fit into the existing slope of the roof whereas dormer
windows can add additional headroom by extending outwards from your roof. The
extent to which you make any changes to the exterior of the property in terms of look
and feel, extensions to the existing roof line, and the locality in which you live may
have an impact on planning requirements. An expert in the field will be able to
advise you on this.
Do I need a specialist company or architect?
You will get the best results by using an architect and/or structural engineer to draw
up the plans, and using a builder with experience in loft conversions. The architect
will normally draw up plans for the building and the structural engineer deals with
scientific and mathematical aspects of ensuring the building is structurally
sound. Architects and structural engineers often work together within the same
organisation or may subcontract work to each other. Look for qualified and
experienced professionals, and when it comes to your builder, check that they are
registered with a professional association such as the Federation of Master Builders
which requires strict standards of quality and best practice. Specialist companies will
also have the skills required to plan the best use of the limited space you may have,
taking into account key structural features such as roof joists and load-bearing walls
along with the best approaches to access; plus they will have the expertise to fit
specialist window types and understand the complexities of plumbing and wiring in
roof spaces. We’d recommend calling in an expert very early in the process as they
will be able to clearly establish the options in terms of the feasibility of the project,
use of space and access arrangements before you make any firm decisions. So,
what other information do you need to know? Well, we’ve prepared a checklist of
key questions for anyone considering a loft conversion below.

2. Loft conversion checklist:
1. Is there enough headroom? You’ll need approximately 2.3 metres at the highest
point.
2. Do you want to add a bathroom? If so will your plumbing system cope with the
extra pressure requirements for piping water up an additional level?
3. Similarly, will your central heating system cope with any additional radiators?
4. What kind of windows do you want or need? Which sides of the property will
provide the best light and/or views?
5. Will you need planning permission? You are permitted to undertake certain
developments to your property without seeking planning permission under ‘Permitted
Development Rights’ legislation (2008), although it’s always best to check with your
local authority as the complex criteria apply. Remember, if your building is protected
or is located in a protected area you may be subject to additional regulations. A
good builder or architect will be able to provide advice on this.
6. If you are in a terraced or semi-detached property you may need to give notice to
your neighbours of your proposed changes under the Party Wall Act (1996). Your
builder will be able to advise on whether this is necessary.
7. Does the loft space have wiring in place or will additional electrical work be
needed?
8. How will we access the space? Is there room for a staircase and if so where will it
be placed?
9. Will the soundproofing, insulation and ventilation be sufficient? Again, your builder
will be able to advice on this.
